8 Analog Audio Inputs - Balanced
The Sigma SSP supports 1pr of XLR type connectors for balanced analog
sources. They are labeled R1/L1.
NOTE: This input conforms to the AES (Audio Engineering
Society) "pin 2 = hot" convention. The pin assignments of these
XLR-type female output connectors are:
Pin 1: Signal ground
Pin 2: Signal + (non-inverting)
Pin 3: Signal – (inverting)
Connector ground lug: chassis ground
Verify that the source components are compliant with this
convention (Classé components are compliant). If not compliant,
contact your Classé dealer for assistance.
NOTE: The Balanced and Single-Ended 2-channel analog audio
inputs can be set for either digital bypass mode (all DSP processing
switched off) or converted to digital format to allow multichannel
processing, bass management, tone control and/or equalization.
If no processing is applied, analog signals remain in the analog
domain, even if not specifically set to digital bypass.
9 IR Input
Use the IR input when the front panel IR window does not have a clear
line-of-sight with the remote control, for instance, when the Sigma SSP
is installed in a cabinet. Attach this input to an infrared repeater system
to route signals from the remote control to the SSP via a mono mini-jack
(3.5mm phono).
The list of available IR command codes can also be used in macros for
sophisticated remote control systems, facilitating the control of the
SSP in the larger context of the complete system.
10 IR Output
Use the IR output to pass IR commands from an external IR transmitter
through the Sigma SSP to another component, when necessary. The
output uses a mono mini-jack (3.5mm phono) with the same properties as
the diagram in the previous section.
11 RS-232 Port
The primary purpose of the RS-232 port is to support the use of external
commands to allow remote control of the Sigma SSP by such systems as
