"Note to CATV system installer: This reminder is provided to call the CATV system installer's attention to Section 820-40 of the NEC which provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical. Example of Antenna Grounding as per National Electrical Code, ANSI/NFPA 70 ANTENNA LEAD IN WIRE GROUND CLAMP ANTENNA DISCHARGE UNIT (NEC SECTION 810-20) ELECTRIC SERVICE EQUIPMENT GROUNDING CONDUCTORS (NEC SECTION 810-21) GROUND CLAMPS POWER SERVICE GROUNDING ELECTRODE SYSTEM (NEC ART 250. PART H) NEC - NATIONAL ELECTRICAL CODE 10) Ventilation -- Slots and openings in the cabinet are provided for ventilation and to ensure reliable operation of the product and to protect it from overheating, and these openings must not be blocked or covered. The openings should never be blocked by placing the product on a bed, sofa, rug, or other similar surface. This product should not be placed in a built-in installation such as a bookcase or rack unless proper ventilation is provided or the manufacturer's instructions have been adhered to. 11) Power Sources -- This product should be operated only from the type of power source indicated on the marking label. If you are not sure of the type of power supply to your home, consult your product dealer or local power company. For products intended to operate from battery power, or other sources, refer to the operating instructions. 12) Grounding or Polarization -- This product may be equipped with a polarized alternating-current line plug (a plug having one blade wider than the other). This plug will fit into the power outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug. 13) Power-Cord Protection -- Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the product. 14) Outdoor Antenna Grounding -- If an outside antenna or cable system is connected to the product, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and builtup static charges. Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information with regard to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode. 15) Lightning -- For added protection for this product during a lightning storm, or when it is left unattended and unused for long periods of time, unplug it from the wall outlet and disconnect the antenna or cable system. This will prevent damage to the product due to lightning and power-line surges. 16) Power Lines -- An outside antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them might be fatal. 17) Overloading -- Do not overload wall outlets, extension cords, or integral convenience receptacles as this can result in risk of fire or electric shock. 18) Object and Liquid Entry -- Never push objects of any kind into this product through openings as they may touch dangerous voltage points or short-out parts that could result in a fire or electric shock. Never spill liquid of any kind on the product. 19) Servicing -- Do not attempt to service this product yourself as opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel. 20) Damage Requiring Service -- Unplug this product from the wall outlet and refer servicing to qualified service personnel under the following conditions: a) when the power-supply cord or plug is damaged. b) if liquid has been spilled, or objects have fallen into the product. c) if the product has been exposed to rain or water. d) if the product does not operate normally by following the operating instructions. Adjust only those controls that are covered by the operating instructions as an improper adjustment of other controls may result in damage and will often require extensive work by a qualified technician to restore the product to its normal operation. e) if the product has been dropped or damaged in any way. f) when the product exhibits a distinct change in performance ­ this indicates a need for service. 21) Replacement Parts -- When replacement parts are required, be sure the service technician has used replacement parts specified by the manufacturer or have the same characteristics as the original part.

It is completely unconnected with timecode clocks, etc. There must be one, and only one, word clock master device in a digital audio system. The DM-24 is capable of acting as a word clock master or as a slave. WARNING There should be one, and only one, word clock master in a setup. Multiple word clocks in a setup may result in noise. which can damage monitoring equipment (speakers and amplifiers). · The integral ADAT interface · Either of the two DIGITAL IN interfaces · Either of the slots occupied by an optional digital interface card. In the case of an AES/EBU interface card, any of the four stereo signal pairs may be individually selectable as the word clock source. · If two DM-24 units are being cascaded, the clock source on a cascaded DM-24 will always be the cascade master DM-24 unit. The master of the cascade chain can select its clock from any available source. The clock can be at 44.1 kHz or 48 kHz or 88.1kHz or 96kHz with some variation possible for varispeed, etc. at ±6%. NOTE Check with the other equipment that you are using to see whether it can be a master or slave, and work out which device will be your word clock master. If the DM-24 is to be a word clock slave in your system, it can accept word clocks from the following sources: · An external clock connected through the dedicated connector · The TDIF-1 interfaces When the DM-24 is linked to an external word clock, it can only use a base frequency clock. Even when many external devices are operating at high sampling frequencies, they output such a base frequency clock. If the external device does not do so, and only outputs a high sampling frequency clock, the DM-24 must be used as the word clock master for the system. TASCAM DM-24 Reference Manual 11 2 ­ User interface Scope of controls The DM-24 has three main types of control screen: system screens, which control parameters for the whole of the system, "global" control screens which affect a certain parameter for a number of channels or modules at once, and the "module" control screens controlling all the parameters for one module. Global screens As the name suggests, the "global" screens allow you to see all the parameters for many channels (the prepost settings for Aux 3 in this example), and to edit them using the POD system as explained here ("PODs" on page 13). Sometimes a key will have two labels. The function described by the lower label (white on blue) is accessed by pressing the SHIFT key so that the SHIFT indicator is lit, and then pressing the appropriate key. In this example, the EXT. CTRL key becomes the MIDI/MC key when the SHIFT indicator is lit. The SHIFT key is a "smart" key. Pressing and releasing it within a short time (somewhat less than half a second) latches it on and off as shown by the indicator being lit. These global display screens are selected using the SCREEN MODE keys to the right of the display screen. Pressing and holding the key for more than about half a second and then releasing it will cause the indicator to go out when the key is released (non-latching). While the SHIFT indicator is lit, the shifted function (the white on blue) is always active. Module screens Alternatively, the screen can be used to show and set the parameters of one module (similar to a channel strip on a conventional console). However, since the number of parameters and features available on the DM-24 is more than a single screen can display, four screens are available for each module, accessed through the soft keys ("Soft keys" on page 15). To use a module: 1 2 Press the MODULE key situated to the left of the display. Use the soft keys ("Soft keys" on page 15) to select a sub-screen (DYNAMICS, EQ, AUX or SETUP). 4 Press the SEL key of the module you want to edit. The screen changes to show the settings for the selected module: 3 Press the FADER LAYER key containing the module whose parameters you want to edit. 12 TASCAM DM-24 Reference Manual 2 ­ User interface--Scope of controls 5 Use the cursor keys, the soft keys and the PODs to make changes to the module's parameters. See below for details. PODs The DM-24 features four rotary controls immediately below the screen, called PODs. These are used as "soft" controls to adjust parameters; that is, they have no fixed assignment to control any single parameter in the console, but are used to control a parameter which is currently highlighted on screen. The POD controls have no end-stop, but are continuously moveable. The value of the parameter controlled by the POD is shown by the graphical onscreen representation of the control. As part of the POD system, cursor keys are included, which move the cursor to the appropriate part of the screen. In addition, the dial can usually be used to move the cursor around the screen. Usually when we mention that the cursor keys can be used for navigation, the dial can also be used, even when this is not explicitly stated. Use the § and ¶ keys or the dial to move the cursor row (shown by a blinking box surrounding the row) up and down. Sometimes in some global screens (as shown here) the box does not cover the full width of When a number of on-screen controls are highlighted by a box surrounding the row containing up to four on-screen knobs, the appropriate PODs are used to control the on-screen controls. If the row also contains on-screen buttons, these are "pushed" by using the Ó and Á keys or dial to navigate to the button in the row (if necessary), and then pressing the ENTER key. a screen row, and the Ó and Á keys or dial must be used to move the box within the row. Fine value settings using the PODs By pressing and holding the 2ND F. key while turning a POD, the value set using the POD can be changed more precisely. This feature is useful when the parameter being changed has many possible values (for example, the digital delay setting) which are first set using the default "coarse" setting, and then fine-tuned using the fine mode with the 2ND F. key. This feature can also be used with the rotary encoders ("Rotary encoders (ring LEDs)" on page 15) to set values entered using these controls with more precision. There is also an option setting which allows PODs and encoders to be used for fine setting of values without the use of the 2ND F. key ("ENCODER OPERATION MODE" on page 20). If this is enabled, pressing the 2ND F. key and turning the POD or encoder changes values in "coarse" or accelerated mode. TASCAM DM-24 Reference Manual 13 2 ­ User interface--Scope of controls Other ways of changing values The JOG/DATA dial can also be used to change parameter values. ENTER key to confirm the value set with the dial. Alternatively, if the parameter is an on-off switching button or a checkbox (a number of checkboxes can be checked individually), press the ENTER key when the cursor is next to the button or checkbox. Checkboxes Radio buttons Parameter values edited without the ENTER key. On/off button If the parameter is a "radio button" (one of a number of alternative options), simply highlight another radio button in the same group, and press the ENTER key to change the state of the buttons in the group. NOTE 1 Use the cursor keys to move the cursor (sometimes shown by a blinking thick box surrounding the parameter to be changed, and sometimes by a symbol beside the parameter to be changed. When the parameter to be changed is highlighted as described above, use the entry dial to set the value (it starts to flash), and the In some screens, (for example the module screens), the active area is marked by a flashing box. The dial is then used for navigation, rather than for setting values. There are other screens, where the dial is chiefly, but not exclusively, used for navigation (e.g. the OPTION SETUP screen ("SETUP" on page 20). If the dial is used for numerical data entry in such cases, it is necessary to press ENTER (the value flashes) before starting to edit the value with the dial, and ENTER once again after editing to confirm the value. 2 Using the faders to change values In the global screens, there is often a special onscreen button, allowing the setting of the values in the screen directly using the faders. To enable this feature, turn the on-screen FADER CONTROL button to ON. The name of this button is prefixed by the title of the screen (here it is an AUX LEVEL screen which is being edited). When the button is turned on: · The faders move to reflect the values set for the current parameter · The fader layer key starts to flash (if it is a channel module layer and not the master layer--see "Fader layers" on page 18). This flashing key shows that the faders are not currently acting as channel faders and that moving the faders will change the currently selected parameter, not the module's signal level. · Moving the fader of a channel changes the value of the current parameter. · Using the POD to change the value of a channel's parameter moves the corresponding fader if the layer is active. If the layer is not active, the fader will be moved to the new position when the layer is made active. The status of the fader control setting is memorized between screens (and even when the DM-24 is turned off and on again). It is therefore possible for the faders to move when the screen is changed. The layer continues flashing as long as the faders are not controlling the channel levels. 14 TASCAM DM-24 Reference Manual 2 ­ User interface--Rotary encoders (ring LEDs) Soft keys At the bottom of a display screen, there may be some "tabs" displayed, which lead to further related screens or pre-defined action. The four keys at the bottom of the screen, beside the PODs, are used as "soft keys" to jump to the screens shown on the "tabs". In this example, the MONITOR and OSC/COM tabs are controlled by soft keys 2 and 3. NOTE It is also possible to jump to the different screens by repeated presses of the key which brings up the screen (in this case, the MONITOR key). These keys are sometimes used to perform a unique "one-off" action, as shown in this screen, where the oscillator can be turned on and off using soft key 1. Soft key pull-up menus In a few screens, for example, the library screens, where many soft keys are used for the "one-off" actions, a soft key (usually soft key 1) is used to bring up a small menu at the bottom of the screen: When such a menu pops up, either the dial or the POD corresponding to the soft key (usually POD 1) is used to select the desired option (which is highlighted in inverse video). Use either the ENTER key or the soft key which was used to pull up the menu to make the selection from the menu. Rotary encoders (ring LEDs) These controls allow you to set commonly-used parameters such as EQ parameters, pan and balance, and Aux send levels. These are not dedicated controls, as the parameters which may be controlled using them are changed using selection keys, but their action is confined to fewer parameters than the POD controls. Like the PODs, these controls are continuously moveable, and have no end-stop. Unlike the PODs, though, the parameters that they control may not necessarily be shown on screen. In order to gain an indication of the current value, the eleven LED indicators arranged in a ring around the knob light to show the current value, as explained in the sections below. These encoders have three different functions: · EQ controls and pan controls to control the EQ settings (gain, frequency and Q) as well as the current channel pan/balance of the currently active module. In this mode none of the encoder indicators (to the left of the encoders) is lit, and the band controlled is determined by the appropriate EQUALIZER key. TASCAM DM-24 Reference Manual 15 2 ­ User interface--Rotary encoders (ring LEDs) · EQ gain controls, where the gain of the four EQ bands is adjusted using these encoders. The encoder EQ GAIN indicator is lit in this case. · AUX send level controls, where either the encoder AUX 1 through 4 indicators or the AUX 5 and 6 indicators are lit (in the latter case, only the two leftmost encoders have any function). See the appropriate section on module operations ("Module operations" on page 49) for full details of the parameters controlled here. NOTE The option described in "Fine value settings using the PODs" on page 13 also affects the operation of these encoders when used in conjunction with the 2ND F. key. Encoders used as EQ gain controls When the encoders are used as EQ gain controls, a unity gain (neither cut nor boost) is represented by the sixth (center) LED being lit, and the two LEDs at the extreme clockwise and counterclockwise positions "half-lit" (dimmed). = on = dimmed = off If the EQ band is set as a high-pass for low-pass filter or is used as a notch filter (depending on the band), all LEDs around the rotary encoder are off: = on = dimmed = off When the encoder is near the center position, but not quite there, the LED next to the center is lit, as well as the "end" LED on the appropriate side: = on = dimmed = off When the encoder is turned either clockwise or counterclockwise, to boost or cut the gain respectively, the end LEDs go out, and the LEDs on the appropriate side of the center light (the more the cut or boost, the more LEDs will light). "Half steps" are shown by dimmed LEDs at the end of the chain. The illustrations below show a relatively small amount of gain applied, and then a little more gain: = on = dimmed = off = on = dimmed = off Encoders used as EQ frequency controls When the encoders are used to set the frequency controlled by an EQ band, only one or at most two LEDs are lit at any one time. As the knob is turned clockwise, the ring LEDs light in turn, representing the position of the knob "pointer". For greater accuracy, intermediate values are shown by two LEDs being lit simultaneously, as in the illustration below: = on = dimmed = off Encoders used as Q controls The Q of an EQ band refers to the width of the filter when it is in notch or peak mode (but not in shelf or 16 TASCAM DM-24 Reference Manual 2 ­ User interface--Rotary encoders (ring LEDs) filter mode). Low Q values affect a wide portion of the spectrum, as shown below: = on = dimmed = off and high values affect a narrow frequency band: = on = dimmed = off Note that "intermediate values" are shown on the encoders by dimmed LEDs, as above. The LED pattern in Q mode is always symmetrical about the upper center indicator. Encoders used as pan controls When the encoders are used to make pan settings, the center pan position is represented in the same way as unity gain on the EQ gain controls: = on = dimmed = off When the pan position is moved to either the left or the right of center, one (or two, to represent intermediate settings) LEDs light to show the current pan position. The illustrations below show the pan position at the hard left position, and then at a position just right of hard left. = on = dimmed = off "Almost center" positions are shown in a similar way to the "almost unity" gain position (that is, the center LED is lit, along with the LED immediately next to it, with the end LED on that side being dimmed). = on = dimmed = off = on = dimmed = off Encoders used as aux send controls When the encoders are used as aux send controls and the control is turned clockwise, the LEDs light up, following the "pointer" of the knob. The number of LEDs lit depends on the aux send level relative to unity position (0.0dB). Below this position, the LEDs light clockwise, with intermediate positions shown by dimmed LEDs: = on = dimmed = off = on = dimmed = off At the 0.0dB point, the LEDs representing values below this point are dimmed, and the "0" LED lights. = on = dimmed = off When aux sends are set above the 0.0dB level, the LEDs above the unity point light in sequence (intermediate positions shown by dimmed LEDs), with the LEDs below the unity point being dimmed. The diagram here shows a setting just below maximum (9.6dB): = on = dimmed = off TASCAM DM-24 Reference Manual 17 2 ­ User interface--Fader layers When two aux channels are linked together, the encoders work in a slightly different way for the selected channel. The first encoder (GAIN) controls the pan for the first two aux sends (1-2 or 5-6) and the second (FREQ) controls the level for these sends. The third (Q) and fourth (PAN) control the pan and level respectively for aux sends 3-4 in the first AUX encoder setting (they have no effect in the second AUX encoder setting). The operation of the pan settings is as described for channel operations ("Encoders used as pan controls" on page 17). Fader layers The DM-24 has sixteen physical "channel" faders and one master fader. However, it is capable of accepting more inputs than faders (up to 32 channels), and also has eight output busses and six aux sends, which are often controlled on conventional mixers using their own faders. LAYER 1­16 17­32 MASTER 1 1 17 B1 To allow the sixteen faders to control the different parts of the console, the faders are arranged in "layers". The layers are arranged as follows (as shown above each fader on the console itself): 2 2 18 B2 3 3 19 B3 4 4 20 B4 5 5 21 B5 6 6 22 B6 7 7 23 B7 8 8 24 B8 9 9 25 A1 10 10 26 A2 11 11 27 A3 12 12 28 A4 13 13 29 A5 14 15 30 A6 15 15 31 -- 16 16 32 -- Ma M M M a. Master fader Use the LAYER STATUS keys located to the right of the master fader, to switch between the three fader layers. The selected key lights and the keys are of different colors, as shown in the table above, so that it is easy to see which layer is currently active, even from a distance. These fader layers also affect the use of the module REC keys (used for arming the tracks of external control devices), the SEL keys, and the MUTE keys. When the fader layer is selected, the faders move to show the current status of the layer. Machine control keys As well as the keys controlling the DM-24 functions, there are also dedicated keys to control external devices connected to the DM-24. Among these keys there are dedicated transport keys which allow basic transport control, as well as controls for auto punch and repeat control of external devices. There are also REC keys at the top of each channel strip, which are used to arm tracks on a connected device. See "Machine Control/Location" on page 80 for full details. A strip of location keys to the right of the display mode keys controls the location facilities on the connected machine. When these keys are used for location, the DISPLAY MODE keys take on their NUMERIC ENTRY functions. The digits entered with these keys are labelled at the left of the keys. These keys are also used to enter digits when naming or renaming library entries ("Setting and editing titles" on page 101). Automation keys The DM-24 has self-contained automation facilities. The dedicated keys to control these functions are all colored purple for easy identification. These keys are the AUTOMATION block by the transport controls, and the purple key near the rotary encoders. There is a separate "shift" key to control the second function of some of the automation keys (and the 18 TASCAM DM-24 Reference Manual 2 ­ User interface--Automation keys undo/redo function of the library. This key is the 2ND F. key (above and to the left of the rotary encoders). These second functions are labeled below the key in inverse lettering: To use these second functions, press and hold the 2ND F. key and press the key whose second function is to be used. The AUTOMATION UNDO key is used in automation operations in order to undo any unwanted changes to automated mixes. The operation of the automation facilities is explained in a separate manual. and press to access Press and hold this key this key this function (KEEP) Automation status As explained in the automation manual, the automation engine can be turned on or off in the main automation screen. When the automation engine is enabled, the word AUTO appears at the top of the screen, together with any automation mode currently enabled. TASCAM DM-24 Reference Manual 19 3 ­ System-wide options The DM-24 provides a number of options which control the overall functionality of the console. These are accessed through the OPTION and DIGITAL screens. Within these screens, you can (in the OPTION screen): · Set up various interface preferences · Set up the way in which soloing works · Set up timecode preferences for synchronization with other units and in the DIGITAL screen · Set up the word sync clock · Choose the digital input and output formats · Define and make settings for the optional slot cards These options are described in detail below: OPTION screen To access the OPTION screen: 1 2 Press the SHIFT key so that the indicator is lit. Press the AUX 1-2/OPTION key. The screen changes to show the OPTION screen. There are four screens available using the soft keys immediately below the display: SETUP, PREFERENCES, SOLO and SYNC/TC. SETUP The following options are available from this screen: ENCODER OPERATION MODE When using the encoders ("Rotary encoders (ring LEDs)" on page 15), or the PODs, the parameter being edited may sometimes have too many values to allow easy setting using the encoder (for example, there are 127 different pan positions). Using the 1Step setting, one "click" of the encoders corresponds to one step in the parameter values. Using the Coarse option allows the changing of the parameter values to be accelerated, with fewer clicks of the encoder. Holding down the 2ND F. key while turning the POD or encoder reverses the usual acceleration mode (if 1Step is chosen, 2ND F. + POD/encoder = accelerated, and if Coarse is chosen, 2ND F. + POD/encoder = accelerated. Use the § and ¶ cursor keys (or dial) to move the cursor to the appropriate fields, and then press the ENTER key to change the value. UPPER BAR DISPLAY This parameter has two options: TIMECODE and SYSTEM. When set to TIMECODE, the top right field of the display shows incoming timecode, and when set to SYSTEM, certain system parameters (clock source, solo mode, etc.) are displayed. LIBRARY DIRECT KEY OPERATION This parameter controls the type of library accessed by the RECALL and STORE, and the + and ­ keys in the LIBRARY section to the left of the screen. There are six choices: Snapshot refers to the overall mixer settings, Gate/Expand to the dynamics processor settings for gate and expander effects, Comp to the dynamics processor settings for compression effects, EQ to the equalization setting library, and Effect1 and Effect2 to the first and second internal effector settings, respectively. If the +/- Key Direct box is checked, this allows instant recall of a library entry selected using the + and ­ keys. LOCATE DISPLAY MODE This parameter determines how a location entry will be shown on the display: in the timecode position (TIMECODE DISPLAY) or as a separate popup display in the center of the screen (LCD Screen Popup). OL/STATUS LED TYPE The OL/STATUS LED indicators above each fader can serve one of two purposes: firstly, if either of the two "overload" options 20 TASCAM DM-24 Reference Manual
