Okay, okay… let’s run some audio through

HUI’s monitor section. If you already performed
the self-demo, then you know the faders work.
The next logical stage is to make sure that HUI
works with audio connected, and with your DAW.

The diagram below shows the simple audio

connections you’ll need to make for the audio
quick start.

1. With HUI’s power turned off, plug in one of

the following:

• A pair of powered studio monitors to 

MONI-

TOR OUTPUTS 1 on HUI’s rear panel; or…

• A pair of speakers (via a power amp) to

MONITOR OUTPUTS 1 on HUI’s rear panel;
or…

• At the very least, a pair of headphones. You’ll

plug these into — wonder of all wonders —
the 

HEADPHONES jack on HUI’s rear panel.

Now you can hear what’s happening.

2. Connect the output of a stereo audio

source (e.g., tape deck or CD player) to the 

L/R

MONITOR INPUTS 1.

3. Make sure the front panel 

MASTER VOL-

UME and LEVEL knobs are off or turned down.

4. Power up HUI by pressing the 

POWER

switch on the rear panel.

5. On HUI’s front panel, make sure the 

INPUT 1,

OUTPUT 1 and OUTPUT 3 buttons are pressed.
They’re in the 

CONTROL ROOM section; their

LEDs will light up. (Be sure the 

1:1 DISCRETE

switch is off.)

6. Turn up the 

MASTER VOLUME knob, the

LEVEL 1 knob, and the LEVEL 3 knob enough
to hear sound coming from the speakers and
headphones.

7. Set the 

TALKBACK MIC switch on the

rear panel to the 

INTERNAL position. With the

TALKBACK LEVEL knob all the way down,
press and hold the 

TALKBACK button, and

slowly turn the 

TALKBACK LEVEL knob up un-

til you can hear yourself talk in the
headphones.

TALKBACK is only assigned to OUT-

PUT 3/PHONES from the factory. You can
assign 

TALKBACK to any of the OUTPUTS

8. Repatch the audio source into various in-

puts and turn on the various front panel input
and output switches accordingly. As a precau-
tion, turn down the 

MASTER VOLUME

control while repatching cables. You’re now
checking all of the various input and output
combinations.

More information on HUI inputs and outputs

can be found in the “Audio Input and Output”
section, which begins on page 17.

If you suspect a problem with the HUI, turn

to the “Troubleshooting” section beginning on
page 25 and run the self-test.
