We think you'll find your Echo Indigo product to be an extremely flexible, high-performance audio tool for your Laptop. Box contents When you opened the box, you should have found the following: · An Indigo, Indigo io, or Indigo dj CardBus adapter · A CD-ROM containing: · Windows Me/2000/XP driver · Mac OS X driver · .PDF Users Guide · Quick Start guide · A six foot audio connection cable (Indigo io & dj only) System Requirements In order to enjoy your Indigo product on a Windows-based laptop, you'll need the following: · A laptop computer running Windows Me, 2000, or XP with a Type II CardBus slot · A minimum 128Mb of RAM (256Mb highly recommended) · Peripheral audio equipment, such as headphones, studio monitors, microphones, musical instruments, etc. 6 Installation Complete installation consists of installing the Windows driver into your system, installing the CardBus card and, if necessary, installing professional audio software. Driver installation Before you can use your Indigo product in your laptop computer, you will need to install the driver. To install the driver, just insert the Echo Indigo CD-ROM into your laptop. The Main Install Window should automatically appear; if it does not, go to My Computer and double-click on your CD-Rom drive. Now, select "Install Windows Driver," and follow the on-screen directions. Please note that Indigo, Indigo io, and Indigo dj work with Windows Me, 2000, and XP; previous versions of Windows are not supported. 7 Hardware installation Once the driver is installed, insert your Indigo product into your laptop. Simply insert the card into any available CardBus slot. It's OK to insert the card while your computer is turned on. Windows should detect that you have installed new hardware. Follow the onscreen directions; your Indigo product should be automatically recognized. For Windows XP, you should select the option "Install the software automatically." Note: this version of the WDM driver has not been digitally signed by Microsoft; for Windows 2000 and XP, you will need to confirm that you want to install an unsigned driver. Once the hardware is installed, a small "Safely Remove Hardware" icon will appear in the system "tray" (usually on the lower right-hand side of the screen). In addition, the blue power indicator on your Indigo will light up. The "Safely remove hardware" icon If you want to remove the card with your computer turned on, the card must first be disabled. To do this, click on the "Safely Remove Hardware" icon in the tray, and select "Safely remove Echo Indigo". You will get a message when it is safe to remove it. Failure to disable the card before removing it could potentially damage the card or the computer. If you purchased an Indigo io or Indigo dj, you also received a 6 foot cable with RCA and 1/4" connectors. Now would be a good time to use this cable to connect your Indigo product to your other audio gear, and to connect a set of headphones. 8 Windows default audio playback device Your Indigo product will automatically be set up as the default Windows audio playback device. To confirm or change this, you need to access the "Sounds and Audio Devices" control panel. The following examples are for the original Echo Indigo product, but apply to Indigo io and Indigo dj as well. Simply select "Start/Control Panel" and open the "Sounds and Audio Devices" control panel. Then, select the "Audio" tab. If you just installed the hardware, you should see "Indigo 1-2 Virtual Out" as the default playback device: If you aren't hearing any audio out of your Indigo, you can use this control panel to make sure that Indigo is selected as your default playback device. These directions are for Windows XP; accessing this control panel under other versions of Windows will be slightly different. 9 Professional audio software To audio software, the Indigo hardware appears as a group of stereo wave devices. You can view the list of these devices either from within your audio software or from the Windows control panel. You'll find these same input and output options available when using your audio recording/editing software, with the devices assignable on a per-track basis. See your software owner's manual for details on how to make these device assignments. NOTE: Some audio software applications require an input device, so we have provided a "dummy" input for Indigo and Indigo dj. You will not be able to record with Indigo or Indigo dj. If you do try to record from the dummy input, you will record silence. This completes the hardware and software installation for your Indigo product. 10 Virtual Outputs Most audio cards with a pair of analog outputs will appear to software as having just that, a single pair of outputs. When one application appropriates the card for its use, all other software is "locked-out" from using the card at the same time. Quite often, musicians find it useful to play back from multiple applications simultaneously. A good example would be playing back digital audio while at the same time using a software synthesizer for MIDI. Another example would be using multi-track editing software. Before multiple tracks can be played back on a stereo device, they must be mixed down within the software to the two output tracks. This takes up extra CPU cycles that might otherwise be dedicated to software effects or some other task. Your Indigo product gets around this by combining the use of "virtual" outputs with its "multi-client" drivers. Indigo, Indigo io, and Indigo dj appear to software as if they have eight separate outputs. These are mixed together with the on-board DSP to produce the actual or "physical" outputs that connect to external equipment without any CPU intervention. Any virtual output can be sent to any actual output along with any combination of other virtual outputs. The levels and routing of the virtual outputs are fully controllable with the Console, which is described later in this manual. An example of this would be using Tascam's GigaStudio with Cakewalk's SONAR. GigaStudio could be set up to play back through Indigo's outputs 7 & 8. SONAR, which combines MIDI sequencing with digital playback, could then play back its MIDI output through GigaStudio while using Indigo's outputs 1 through 6 for six separate tracks of digital output. This gives your Indigo product most of the advantages of products with eight separate analog outputs, without the added expense of the extra converters or having to use an external mixer to mix the outputs down to a final pair of stereo outputs. 11 Console3 A "virtual control surface" application called Console3 is included with the Indigo driver. The Console allows you to control the audio playback functions of your Echo Indigo product, and it brings these controls to a single easy-to-use location. If you're curious, the name "Console3" means that this is Echo's thirdgeneration design for a software console. Running the Console Once you have run the installer, you will find the console under your Start menu under the group "Echo Digital Audio." Here, you have two options for running the console: "Show all Console3 windows" and "Start the tray icon." If you select "Start the tray icon," a red "Echo" icon will be placed on your system tray. This is called the launcher. Double-clicking the launcher icon will display a console window for each Echo card in your system. If you only want to open a console window for one of your Echo cards, rightclicking the launcher icon will display a menu that lists the cards in your system. Select the card corresponding to the console you want to display. If you want to make sure that the tray icon will always be there, then select "Auto-start the tray icon." If you select "Remove from tray," the icon will vanish. All of your open console windows will close as well. 12 Console Window The basic metaphor for the console interface is a digital mixing board, and it works in terms of output busses. An output bus is a stereo pair of outputs on your hardware. For example, analog outputs 1 and 2 are an output bus. The console window allows you to control what is mixed and sent to that output bus. With Indigo io you will also be able to control input monitoring. 13 Bus select (Indigo dj only) The bus select panel is the area in the middle right of the Console. Each bus has its own button marked with an A (for analog) and a channel number pair. The button in the "down" position is the currently active bus. Clicking on an output bus button simply selects the settings that are displayed. In this case Analog out 3/4 (A 3-4) is the active bus. This means all parameters such as volume, pan, and mute apply to the audio coming out Analog outputs 3 and 4 of Indigo dj. To select an output bus, click on one of the buttons. Alternatively, you can use the function keys F1 and F2. Master Output Bus Control The master bus control is the area on the bottom right of the Console. The example above shows the Indigo dj Console. At the bottom is the label "Analog out 3/4." This indicates you are currently controlling everything mixed to analog outputs 3 and 4. Indigo and Indigo io only have controls for Analog out 1/2. The mute buttons and faders affect everything being mixed to this bus. Holding down the Ctrl key and clicking on a fader will set that fader to 0 dB, and clicking on the readout below the fader will allow you to enter a numerical value for the fader setting. The gang button, marked with a "G," sets the gang mode. If you are in gang mode, the mute buttons will work together for the left and right channels; for example, clicking the mute on one channel activates the mute button on the other channel. Also, ganging the faders ties them together so they will maintain their relative placement with regard to each other. Holding down the Shift key reverses the state of the gang button; that is, if the gang button is down, holding down shift puts you in non-ganged mode and vice versa. 14 Analog Inputs (Indigo io only) The controls for the analog inputs are on the left side of the Console and have the label "Analog in" at the bottom. There is one strip, or input monitor, corresponding to each of Indigo io's two physical analog inputs. 15 At the top is the peak meter for this channel, labeled in decibels. Under the peak meter is the monitor pan slider; this pans the input channel between the two channels of the output bus. Holding down the Ctrl key and clicking on a pan slider will set the slider to the center position. Note that this does not affect your recording. Below the pan slider is the monitor mute. This controls whether or not you want this input channel to be mixed directly out to the currently selected output bus. Again, this does not affect recording. This is followed by the monitor fader, which controls the input monitor level. Like the pan and mute controls, this does not affect your record level. Also, clicking on the readout below the fader will allow you to numerically enter a fader setting. The analog inputs also have gang buttons, and their operation is the same as the gang button for the master outputs. Playback Strips The controls for the level of audio being played by an application are found in the middle of the Console and have the label "Virtual out" at the bottom. Each Indigo Console has multiple playback strips ­ one for each virtual output. Each playback strip allows you to pan, mute and change the level of the audio signal that is being sent to your Indigo product's physical outputs. Each virtual output can be mixed in any combination to your Indigo product's analog outputs. Adjusting Playback Volume Output volume adjustments are made in the digital domain. When you lower a volume fader below 0dB, you are actually decreasing the number of available bits, thereby taking away from the potential dynamic range of the system. Therefore, we suggest that whenever possible you leave the output faders set to 0dB, and perform any necessary attenuation with the volume knob on your Indigo product or with an external mixer. When the playback volume controls are set to 0dB and the input signal approaches the maximum pre-clipping level, you can achieve the full 24-bit dynamic range of the system. 16 Console Sessions Console settings can be saved as a console session to be reloaded later. All volume levels, pan settings, mutes and gang settings are saved. To save a console session, click the "Save" button in the console. To load a previously saved session, click the "Load" button in the console. The current session can be "fast saved" by pressing the F key; this will overwrite the most recently opened session file with the current settings. By default, a directory with your card name is created, and all sessions for that card are saved to it. Sessions are not cross-compatible between different types of hardware; for example, an Indigo io session cannot be used with Indigo dj. The various options available in the "Settings" dialog are not saved as part of the console session. 17 Console Settings Clicking the Settings button at the top of the Console shows a dialog box for altering console settings. The Settings dialog gives you four different tabs to choose from: "Driver," "Console," "GSIF," and "About." Driver tab Here you can do two things: lock the sample rate and tell the driver whether or not to synchronize wave devices. Locking the sample rate Locking the sample rate can be very important, since Windows will frequently try to set the hardware to the highest supported sample rate. Then, Windows sample rate converts between that rate and the rate at which you are playing or recording. For instance, you may be trying to play at 44.1 kHz, but Windows sets the hardware to 96 kHz and converts between the two. This is undesirable because you may be trying to do a digital transfer at a specific rate. In addition, sample rate conversion will reduce your audio quality and consume a great deal of CPU power. Locking the sample rate forces Windows to only use the hardware at the locked rate. In general, we recommend you set the sample rate first in your audio application. Then, lock that same rate within the console. Locking the sample rate is not really necessary for applications that do not use the legacy wave/MME interface (such as SONAR, Cubase, etc.). 18 Synchronize wave devices This is mainly for developers who are using tools like Visual Basic or Delphi and want the inputs and outputs to be totally independent. Unless you have a good reason to turn it off, you should leave this switch on. Also, if you are running multiple applications on one card and you can't get it to work, try un-checking this box. Console tab The console pane lets you control settings that effect console sessions and the view of the console. Load last session when console starts Checking the box causes the last console session you had open to be loaded when you re-open the console. Auto-save session when console exits Checking this box automatically saves the currently opened console session when exiting the console. Always on top Checking this box causes the console to always remain in front of other windows, even when it is not in focus. 19 GSIF This window allows you to set the latency of GigaStudio in terms of samples. Select the value here that provides the best tradeoff between performance and reliability. These settings have no effect on any applications other than GigaStudio. About This displays the console version and driver version numbers. We feel that this is the single most exciting feature of the console. 20
