Caution! There are no user-serviceable parts inside the Proceed Digital
Surround Decoder. Please contact your dealer for assistance
if you need to swap modules in order to install this or any
other option.
The pin assignments of these XLR-type male outputs conform to the inter-
national AES standard, and are as follows:
1 2
3
Pin 1: Signal ground
Pin 2: Signal + (non-inverting)
Pin 3: Signal – (inverting)
Connector ground lug: chassis ground
Refer to your power amplifier’s operating manual to verify that the pin as-
signments of its input connectors correspond to the Digital Surround De-
coder. If not, wire the cable so that the appropriate output pin connects to
the equivalent input pin, or reverse the leads of both your speaker cables to
“reverse the reversal” and restore correct polarity.
High quality single-ended outputs are also provided for compatibility with
power amplifiers lacking balanced inputs.
Connect the left and right auxiliary outputs of the Digital Surround De-
coder to the appropriate inputs on your power amplifier(s).
10 CONTROL/COMMUNICATIONS
The Digital Surround Decoder provides for robust communications be-
tween components using this module. The uppermost
comm. port is re-
served for communications with the PAV, which provides the user interface
(among other things) for the PDSD. Connect a modular RJ-11 cable (sup-
plied with the Digital Surround Decoder) between this port and the corre-
sponding port on the PAV.
Important! If you are using a PAV that was built before early 1997, your
dealer will need to perform a simple hardware update to your
PAV prior to being able to use it with the Digital Surround
Decoder. This update will provide the necessary physical
connection at the PAV end.
If your PAV already has the communication port next to its
power switch on the rear panel, then your dealer will need
only to update its EPROM with the one that came with the
PDSD for it to work seamlessly with the Digital Surround
Decoder.

Surround Decoder. Please contact your dealer for assistance
