for Surround
signals that are not synchronized with re-
spect to the others connected to the Model
760-03, even if the sample rate is identical.
The only compromise is that the SRC pro-
cess adds a fixed input-to-output (group)
delay of approximately 1 millisecond, a
value that shouldn’t impact most installa-
tions. As such, it’s recommended that the
sample rate converter remain enabled.
However there might be special cases
where this resource isn’t desired and it can
be disabled.
Post-Fader Stereo Digital and
Analog Monitor Outputs
In addition to the post-fader surround digi-
tal and analog monitor outputs, separate
post-fader stereo digital and analog moni-
tor outputs are also provided. By default
the stereo outputs can be enabled by a
user. In applications where stereo monitor
loudspeakers are not connected to either
of the post-fader stereo monitor outputs,
the outputs can be disabled. This can
minimize confusion, preventing a user from
attempting to select the post-fader stereo
digital and analog monitor outputs.
Bass Management
The Model 760-03 incorporates flexible
and sonically excellent bass management
capabilities which can impact both the digi-
tal and analog post-fader monitor outputs.
It is, however, limited to functioning only at
sample rates of 44.1, 48, 88.2, and 96 kHz.
Five configuration parameters are used to
enable or disable bass management as
well as to select the characteristics of the
associated audio filters. While the settings
are simple to make, great care must be
taken in first reviewing the entire monitor
system. Only after a full understanding of
the performance of the associated sur-
round and, if present, stereo loudspeaker
systems are determined can a plan for
bass management be established.
Bass management can be enabled so that
the function is active when the surround
post-fader monitor outputs are enabled. It
can also be independently enabled so that
it can be active when the stereo post-fader
monitor outputs are enabled. By default
bass management for both outputs is
disabled. The crossover point of the bass
management filters can be selected from
among four choices: 40, 50, 60, or 80 Hz.
The slope of the low-pass and high-pass
filters associated with bass management
can be independently selected. The choic-
es are 12 dB-per-octave or 24 dB-per-
octave with the latter being the default.
Mute/Solo Bass Management
Mode
The Model 760-03’s mute/solo function can
be configured for how it performs in appli-
cations where bass management has been
enabled. This is a somewhat-esoteric topic
but can be important in certain situations.
The default setting for the mute/solo bass
management mode is for pre-bass man-
agement. This means that if a channel has
been selected for, as an example, soloing
then the bass management filters will send
any applicable low-frequency content to
the post-fader digital and analog subwoof-
er outputs. So in this case the solo function
is really an “input channel” solo since the
actual acoustical energy associated with
that channel will be reproduced by both the
main channel and subwoofer loudspeak-
ers. So while one is “soloing” a channel (or
set of channels) two or more loudspeakers
may be reproducing the signals.
