External Amplifi er Connections
Power & IR Control Connections
Power Control (Trigger) Connections
The Model 976 off ers two 12VDC Trigger outputs
that can be used to control compatible external
components such as amplifi ers, motorized projec-
tion screens, and blinds. When these outputs are
enabled, the Model 976 applies power (12 volts
DC) to these output jacks. By default, Trigger Out
1 is set to be activated with all inputs. This is the
recommended trigger to use to activate amplifi ers
automatically.
Use a 3.5mm mono cable to connect the Trigger Out
1 or 2 of the Model 976 to a matching “Trigger” or
“Control” input on the external component. Once
the two units are connected, the external compo-
nent will turn on when the Model 976 is on (if the
active input is set to use that trigger) and off when
the Model 976 is turned off . If the amplifi er has a
main power switch (often on the back), the power
will probably have to be turned on at this switch
before the DC trigger signal will work.
Unbalanced (RCA) outputs
The 7.2 CH outputs provide unbalanced pre-
amplifi er outputs for the front left, front right,
center, left and right side surround, left and right
rear surround, and two subwoofer speakers. If
your amplifi er(s) or powered subwoofer(s) do not
include balanced (XLR) inputs, these unbalanced
outputs should be used to connect the Model 976.
When a powered subwoofer is used, connect the
Subwoofer output jack to the Line Input jack on
your subwoofer and follow any specifi c connec-
tion and/or confi guration instructions supplied
with the subwoofer. If your subwoofer is a passive
speaker, connect one of the subwoofer output
jacks on the Model 976 to the input of the ampli-
fi er used to power the subwoofer, and then con-
nect the subwoofer speaker itself to the amplifi er.
IR Input and Output
The Model 976 includes IR input and output ports
that can be used with external IR remote sensors.
To use the Model 976’s remote when the Model
976 is concealed, connect an external IR sensor
to the IR Input. A 3.5mm mono cable may be
connected to the IR output to pass the IR signals
through to an additional concealed component,
such as a Blu-ray Disc player.
IMPORTANT NOTE: Before attempting to plug any
jacks into any power amplifi er verify that the power
amplifi er is turned off and/or disconnected from the
AC mains. Failure to do so can potentially result in
severe damage to your amplifi er and loudspeakers.
The Model 976 is a Surround Sound Processor,
and as such does not include amplifi ers. It must
be connected to one or more power ampli-
fi ers, such as Outlaw Audio’s Model 7140 or
Model 7700, so speakers can be connected to the
amplifi er(s). The Model 976 off ers two types of
pre-amplifi er outputs that can be used to connect
to those amplifi ers.
Balanced (XLR) outputs
The 7.2 CH Balanced Outputs provide XLR
balanced outputs for the front left, front right,
center, left and right surround, left and right rear
surround, and two subwoofer speakers. These XLR
connectors provide a “balanced” connection that
is better at rejecting ambient noise from sources
such as power cables. If balanced (XLR) inputs
are available on your amplifi er(s) or subwoofer(s),
these should be used to connect the Model 976 to
those components.
Amplifi er Outputs
Connect either the balanced (XLR) or unbalanced
outputs to your external amplifi er(s) and subwoofer(s). If
necessary, you may use a combination of balanced and
unbalanced connections.
Trigger Connections
Connect either Trigger 1 or Trigger 2 to a
compatible DC trigger input on an amplifi er
or other device.
IR Input/Output
Use with an external IR
remote sensor or RF-to-
IR device.
