INSPECTION Your SDP-20 was carefully packed at the factory in packaging designed to protect the units in shipment. Before installing and using your unit, carefully examine the packaging and all contents for any signs of physical damage that may have occurred in transit. (Note: Nady Systems is not responsible for shipping damage. If the unit is damaged, do not return to us, but notify your dealer and the shipping company immediately to make a claim. Such claims must be made by the consignee in a timely manner.) CONTENTS: · Instruction manual · SDP-20 (verify that the unit's serial number is same as shown on shipping carton) · AC Power cord · Warranty Card RACK MOUNTING The SDP-20 fits into one standard 19" rack unit of space (1 3/4"). Parts of the unit can become very warm during use. This is normal during operation. Care should be taken to ensure that there is enough space around the unit for cooling (at least 12" or 30cm). Do not place the SDP-20 on high temperature devices such as power amplifiers, etc., or the unit may overheat in operation. Also, do not place the unit on speakers as this may cause them to move and/or fall due to speaker vibrations. Although the unit's chassis is shielded against radio frequency (RF) and electromagnetic interference (EMI), extremely high fields of RF and EMI should be avoided. POWER CONNECTION The SDP-20 has an internal power supply and is designed to operate from an external AC source. Power requirements for electrical equipment differ from area to area. Be sure to confirm that the voltage selected by the voltage selector switch on the back panel is proper for your area (120VAC/60 Hz or 230VAC/50Hz) per the information below: Europe (except UK): 230V, 50Hz UK and Australia: 240V, 50Hz USA and Canada: 120V, 60 Hz For other areas, please check with local authorities. When ready to operate, plug the AC cord into the power source. Make sure that the unit is turned off before connecting to the AC power source to avoid possible loud transients which can damage your speakers or your ears, especially when monitoring with headphones. 4 CONTROLS AND CONNECTORS (12) (13) FRONT PANEL (1) (2) (3) (4) (5) (6a) (6b) (7) (8) (9) (10) (11) 7. UP/LEFT & 250HZ EQ SELECT KEY Use this key in NORMAL/EDIT/EQ MODE to select effect type, edit parameters, or edit EQ parameters. When the corresponding LED lights, the EQ parameters in this frequency range can be changed and the PROGRAM/VARIATION DISPLAY (6a) will indicate present value (64 = 0dB, 127 = +12dB and 0 = -12dB) 8. DOWN/RIGHT & 1KHZ EQ SELECT KEY Use this key in NORMAL/EDIT/EQ MODE to select effect type, edit parameters, or edit EQ parameters. When the corresponding LED lights, the EQ parameters in this frequency range can be changed and the PROGRAM/VARIATION DISPLAY (6a) will indicate present value (64 = 0dB, 127 = +12dB and 0 = -12dB) 9. EDIT/SAVE/LOAD/EQ SELECTOR & 5KHZ EQ SELECT KEY Use this key to change MODES. The MODE selected is indicated on the MODE DISPLAY (6b). When the corresponding LED lights, the EQ parameters in this frequency range can be changed and the PROGRAM/VARIATION DISPLAY (6a) will indicate present value (64 = 0dB, 127 = +12dB and 0 = -12dB) 10. BYPASS/ENTER & 16KHZ EQ SELECT KEY Use this key to turn effect on or off. With BYPASS selected (effect off), both the EFFECT TYPE DISPLAY (4) and the PARAMETER DISPLAY (5) will be off and the PROGRAM/VARIATION DISPLAY (6a) will indicate "OFF". In SAVE/LOAD MODE, this functions as the confirm key (ENTER). (Note: In OFF state, the EQ is not off and can still be edited.) When the corresponding LED lights, the EQ parameters in this frequency range can be changed and the PROGRAM/VARIATION DISPLAY (6a) will indicate present value (64 = 0dB, 127 = +12dB and 0 = -12dB) 11. MIDI SELECT KEY Use this key to select MIDI control mode. The corresponding LED indicator will light and the PROGRAM/VARIATION DISPLAY (6a) will display "256" to indicate that the unit is in MIDI control mode. 12. VALUE ADJUSTMENT CONTROL Use this control to select effects, edit effect parameters and edit EQ parameters. 13. POWER SWITCH Use this switch to power unit ON or OFF. The integrated LED will light when the unit is ON. Before turning on this unit, verify connection to the proper voltage AC source, check all connections and turn down the level controls of equipment connected to the outputs. 1. INPUT GAIN CONTROL Adjusts the input level of the audio signal to the unit. 2. OUTPUT LEVEL CONTROL Adjusts the output signal from the unit to match the differing requirements of connected equipment. 3. INPUT LEVEL DISPLAY 6-segment stereo LED display indicates the level input to the unit. 4. EFFECT TYPE DISPLAY 8 LED display indicates which of 8 possible effect types has been selected. 5. PARAMETER DISPLAY Each effect has up to 6 editable parameters. The effect type selected is indicated by the 3 LEDs in the column on the left side of this display. The LED above the 6 columns to the right indicates the editable parameter selected for the chosen effect. This display is only valid in EDIT MODE.
