Full-On Major League Hookup
Scenario: Any audio application with a
plethora of inputs to stereo final master. HUI is
the control room hub, so the mains or control
room outputs of the mixer and DAW feed HUI.
Source Material: Live audio, synths, sam-
plers, multitracks, DAW tracks, etc.
Outputs: HUI’s
OUTPUT 1
is fed to a head-
phone amp/mixer for further distribution to
multiple headphone pairs.
OUTPUT 2
goes to
a dubbing or mastering deck.
OUTPUT 3
is
routed to a speaker selector box so multiple
speaker pairs can be used.
Audio Hookup:
Tracking: Normally, live audio goes either to
tape or hard disk, while MIDI-sequenced
synth, samplers, etc. are used to play against
during overdub or as final mixdown “virtual”
tracks. Virtual tracks are good for saving tape
and hard disk space, and avoiding added noise
through additional audio transfer and tracking.
• The mixer mains, the mastering deck, and
the DAW feed HUI’s inputs, for control room
monitoring purposes.
• The mixer aux sends, DAW aux send buses
(available in Pro Tools 4.1, for example), and
HUI
OUTPUT 1
feed the external head-
phone mixer — all for extra and/or remote
monitoring purposes.
• HUI
OUTPUT 3
feeds a speaker selector for
A/B comparison of big vs. small speakers,
mono level-balancing, etc.
• Mics are used as: direct-to-DAW feeds for
boosting signals to line level, or as extra mic
preamps to feed line inputs on the mixer.
• The engineer’s talkback mic is set to feed all
of the monitor outputs.
• A stereo compressor/limiter feeds the in-
serts as two mono compressor/limiter units.
Digital Control Hookup: HUI MIDI I/O, as
well as MIDI sync and triggering to all instru-
ments to sync with digital audio from the DAW.
Special Notes: Use the
MONO
button in the
Control Room section to determine phase cancel-
lation during recording (i.e., mics cancelling out
each other).
MONO
is also a useful check for
stereo material that is to be aired for mono
broadcast (again, as a level balance and phase
cancellation check).
