AUDIO INPUT AND OUTPUT
Signal Flow Primer
Monitoring the audio signals can be done in
either mono, stereo, or surround-sound (with
six discrete channels). The overall input vol-
ume is controlled by the
MASTER VOLUME
knob. The outputs are controlled by three sepa-
rate output level controls and toggle switches
(labeled
OUTPUT 1, 2,
and
3
). HUI uses DCAs
(digitally controlled amplifiers) to control in-
ternal signal flow completely independent of
the DAW. The signal is distributed according to
which inputs and outputs are enabled.
Stereo Monitor Mode — enabled inputs’ stereo
signals are
summed
into one stereo signal
In stereo monitor mode — with the
1:1 DIS-
CRETE
switch turned
off
— any of the three
stereo input sources may feed any of the stereo
MONITOR OUTPUTS
(
OUTPUT 1, 2,
and
3
).
Any or all of the three stereo inputs can be
monitored simultaneously. That is, it’s up to you
to disengage an input if you don’t want to moni-
tor it. Any and all of the
OUTPUTS
can be
active at once, so you can send outputs to vari-
ous pairs of speakers and various combinations
of speaker pairs and recorders.
AUDIO INPUT AND OUTPUT
1:1 Discrete Monitor Mode — enabled inputs are
not
summed
When HUI’s
1:1 DISCRETE
switch is engaged
(the LED will light), the control room section be-
comes a discrete surround matrix capable of
either standard 4.1 surround (L/R/Center/Sur-
round/subwoofer), or 5.1 surround (L/R/Center/
Surround L/Surround R/subwoofer).
You can set up your DAW audio output con-
figuration so that the various “stem” outputs
correspond to the physical outputs on the DAW
audio interface. These outputs are then patched
to HUI’s
MONITOR INPUTS 1, 2,
and
3
.
With
1:1 DISCRETE
engaged, the output
LEVEL
controls for
OUTPUTS 1, 2,
and
3
act as
trims for the respective mix stems (L/R/Center/
Surround L/Surround R/subwoofer). The
MAS-
TER VOLUME
controls the level for all three
output pairs, allowing you to trim the overall
level of separate surround amp feeds.
Keep in mind that, when in discrete mode,
output pairs share a common stereo level con-
trol and individual outputs cannot be adjusted
independently.
Note: The
DIM
and
MUTE
controls operate
on all outputs, regardless of whether HUI is in
discrete mode.
MONO
, too, sums all inputs to-
gether, regardless of mode. Refer to the audio
block diagram on page 30 for further info.
