AC-3 Operation
AC-3 is an audio compression system (designed by Dolby Labs) that
transports up to 6 audio channels. The AC-3 signal is compressed and
passed through a single AES transport stream, and a special decoder is
required. The DMIX-41 can
not mix AC-3, audio, but it can pass and
switch up to four AC-3 streams under the following conditions:
•
Inputs are not equipped with SRCs (sample rate converters).
•
Remote control “input mute” switches are connected. Refer to
DMIX-41 Remote Control ” section for details.
•
The unit is set for 24-bit processing. Refer to the “ DMIX-41
Internal Jumpers ” section for details.

Basic — Mixing Workstation Audio
In this application, digital audio from two workstations is
combined, mixed in the DMIX-41, and recorded on DAT. The
DAC provides monitoring capability. Remote switching is not
required. If the DMIX is equipped with SRCs, inputs can be
asynchronous. If the DMIX is
not equipped with SRCs, all
inputs must be synchronous.
