can run from the audio system's own isolated 'dirty' power supply, or from an external power supply.

Up to 255 different spiels can be stored on each Digital Audio Repeater. These can be any length

from 1/35th of a second on up. They can be accessed at random through the serial port or through the
AUX PORT. The AUX PORT can be told to use a 'one of eight' style selection, or a parallel 8 bit binary
input.

If DR-300 or DR-400 cards are used in a basic audio system, you can use their Voltage Controlled

Amplifiers (VCAs) to change the volume of the output from each card. Each card has its own 0 to 10
volt input for the VCA, or you can attach the VCA to one of eight VCA BUS lines if you need to control
the volume of more than one card at a time.

The following illustrates the four Digital Audio Repeater / Mixer card options. (The GLOBAL / MIX BUS

structure of each card is shown in the GLOBAL LISTEN mode.)
