Output Controls; Adjusting Record And Playback Levels; Synchronizing Multiple Devices - Echo Darla Owner's Manual

Remember that all of the inputs are continuously monitored by all of the
outputs at some level. The degree of attenuation (or muting) of that level is
set by the monitor controls. The console program constantly maintains a
level setting for each of the 8 monitor paths it controls. Clicking on an
output selection button simply selects the settings that are displayed.

Output Controls

The right hand side of the console is dedicated to the controls for output
channels one through eight. The available controls are: Gang, Mute, Solo,
meter on/off and volume slider.

Adjusting Record and Playback Levels

Darla's output volume adjustments are made in the digital domain. When
you lower a volume slider; you are actually decreasing the number of
available bits, thereby taking away from the potential dynamic range of the
system. To avoid this, we suggest that whenever possible you leave the
output sliders set to their maximum positions, and perform any necessary
attenuation on your external mixer. When the Darla playback volume
controls are set to maximum and the input signal approaches the maximum
pre-clipping level, you can achieve the full 20-bit dynamic range of the
system.

Synchronizing Multiple Devices

Darla is designed to work alongside other audio equipment within a
complete Windows system. If you are planning on using Darla with other
audio equipment, please note the following:
The Darla Windows drivers (echogals.drv and echogals.inf) included in this
package supports multiple Darlas within the same system. In addition, your
new Darla will operate with Layla and Gina. Darla can also peacefully
coexist with audio equipment from other manufacturers, but be aware that
operating alongside another product is not the same as operating with it.
Darla does not support external synchronization. In order for accurate
synchronization to occur, all audio products in your system must support
some form of synchronization such as Midi Time Code, S/PDIF or Word
