Pre-Fader Surround Digital Monitor
Output
The pre-fader surround digital monitor
output channels are intended to connect
to metering, measurement, or other
signal monitoring equipment that requires
uninterrupted, full-level digital audio signal
sources.
Stereo Input C Direct Digital Monitor
Output
The stereo input C direct digital monitor
output is intended for use in site-specific
applications. It provides an uninterrupted,
full-level digital audio signal source that
is post-SRC and input delay in the signal
chain.
Post-Fader Surround Digital Monitor
Output
The post-fader surround digital monitor out-
put channels are designed for connection to
digital inputs on audio amplifiers associated
with monitor loudspeakers. Alternately, they
could be connected to the inputs of loud-
speakers that contain integrated amplifiers
with digital audio input capability.
Post-Fader Stereo Digital Monitor Output
The post-fader stereo digital monitor output
channels are intended to support a stereo
loudspeaker system, either by connecting
to the digital input of an amplifier associ-
ated with a set of loudspeakers or directly
to a set of amplified speakers that provide
digital inputs.
Analog Monitor Outputs
The connector labeled Analog Monitor
Outputs provides access to the Model
760-03’s 6-channel (5.1) surround and
2-channel stereo analog monitor outputs.
The surround analog monitor output chan-
nels are intended to connect to analog
inputs associated with the surround loud-
speaker system incorporated in a facility.
The stereo analog monitor output allows
support for a secondary set of stereo
monitor loudspeakers.
The analog monitor output channels are
designed for connection to audio amplifiers
associated with monitor loudspeakers or
to the inputs of loudspeakers that contain
integrated amplifiers. The analog monitor
outputs are electronically balanced and
will perform optimally when driving loads of
2000 (2 k) ohms or greater. In most appli-
cations 3-pin male XLR connectors will be
used to interface with the inputs on the as-
sociated amplifiers or amplified speakers.
In this case the + terminal would go
to pin 2 of the XLR, the – terminal to XLR
pin 3, and the shield terminal to XLR pin 1.
Balanced operation of the analog monitor
outputs is the preferred connection method
but unbalanced operation does not pose a
problem. To connect to an unbalanced load
connect the + terminal as signal high, and
only the Model 760-03’s shield terminal as
the signal low/shield. Leave the – terminal
unconnected. For correct unbalanced op-
eration, it is important not to connect – and
shield together.
The wiring scheme used by the D-submin-
iature connector complies with AES59-
2012, as made popular by TASCAM. A
wiring assembly prepared for the Model
760-03’s analog monitor outputs is identi-
cal to that of a TASCAM-type output as-
sembly. Please refer to Figure 6 for the
exact connection details. Again note that
unlike a TASCAM-type assembly, the
Model 760-03’s D-sub connectors use
4-40 threads.
