Quick Setup
Why You Shouldn’t Connect the Channel’s Output to a Mic Level Input.
The bottom line: you will get an unsatisfactory noise level. The Channel is designed to generate a line
level output from a mic level input. It optimizes the signal to noise ratio by giving you a strong signal far
above the preamplifier’s basic self noise level. This strong output signal can be up to 65dB higher than
the mic signal. It is perfect for a standard line input of a mixer or console but can overload a mic input. If
you have no other choice but to plug the Channel in to a mic input, turn that mic input’s gain all the way
down. If the signal still clips the input, try bringing down the Channel output level.
GATING
Shows when
the gate
is closed
or closing.
When the
light is off,
the gate is
fully open.
DEPTH
Lets you set how much attenuation the
gate will deliver. Use the lowest attenuation
that’s needed to reduce room wetness,
breath, or background noise. Usually 6 to
15dB is sufficient. Fully CCW is off.
BIG-BOTTOM
FREQ
Adjusts the
frequency
below which
enhancement
takes place.
PARAMETRIC EQ
Works like a standard parametric band
with tune, Q, and boost/cut controls.
AURAL EXCITER
FREQ
Adjusts frequency
above which
enhancement
takes place.
AURAL EXCITER
AMOUNT
Adjusts the
strength (boost) of
the Aural Exciter
effect.
BB/EQ/AX
ON
Switches the
BB/EQ/AX
on/off.
Provides full
true bypass
of the circuits
when off.
OUTPUT
Adjusts the

cessed output
level as seen
on the VU
meter.

WORD CLOCK
BNC input and output jacks.
OUTPUT CONTROL
Once all processing and equal-
ization is set where you want
it, the output level may need to
be adjusted. Do not let the peak
level frequently exceed -6dBFS.
This will make sure the digital
output carries well through sub-
sequent mixing and processing.
When using the analog output,
adjust the level to produce the
desired average output level
(0VU) as seen on the outboard
equipment’s meters.
DIGITAL AUDIO
The Channel supplies industry standard stereo
AES/EBU, S/PDIF, and TOSLINK digital audio
outputs. The single mic channel appears
on both stereo channels as a mono signal.
Sample rate and word clock options are all
available at the front panel. The word clock
selection LEDs will flash when no clock signal
is present and light solid when locked.
MIC INPUT
Works with all standard
microphones, phantom
powered or passive.
Phantom power acti-
vated from front panel.
COUGH SWITCH
Allows you to
silently mute the
output on the
fly using a hand-
held, desktop, or
floor switch.
BIG-BOTTOM
