Two backplanes are presently available for the AAV-HD-DMUX and AAV-SD-DMUX.

The AAV-DMUX-C1 is the standard backplane/ connector module with BNC video electrical
inputs and outputs. A 25 pin d-sub type connector is provided for the analog and AES3 audio
inputs and outputs. The pin configuration used is the industry standard TASCAM DA-88 type
so that commercially available 'snakes' may be used.
The AAV-HD-DMUX-C6 is a backplane with series resistors for the analogue outputs to allow
the module to be used with 600 ohm lines. This module should only be used when there is
requirement for a matched impedance as it also introduces a 6 dB level reduction. The
module can not produce analogue audio signals higher than +18 dBu when the outputs are
correctly terminated in 600 ohm with this backplane.
The standard AAV-DMUX-C1 backplane is compatible with 600 ohm equipment, as the
module will drive a 600 ohm load without any problems. The standard backplane should be
used if there is not a requirement for matched impedance.
