Quick Setup
Why You Shouldn’t Connect a 230’s Output to a Mic Level Input.
The bottom line: you will get an unsatisfactory noise level. The Model 230 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 will overload a mic input. If
you turn down the 230’s output level enough to stop overloading the mic input of your mixer, then your
mixer’s preamp gain will amplify the natural noise floor far too much, causing a noisy signal.
DEPTH
Lets you set how much attenuation the
gate will deliver. Use the lowest attenu-
ation that’s needed to reduce room
wetness, breath, or background noise.
Usually 6 to 15dB is sufficient.
BIG-BOTTOM
TUNE
Adjusts the
frequency
below which
enhancement
takes place.
Helps mainly
male voices.
PARAMETRIC EQ
Works like a standard parametric band
with tune, Q, and boost/cut controls.
AURAL EXCITER
TUNE
Adjusts frequency
above which
enhancement
takes place.
AURAL EXCITER
MIX
Adjusts the
strength (boost) of
the Aural Exciter
effect.
BB/EQ/AX
ON
Switches the
equalizing
chain in and
out. Provides
full true
bypass of the
circuits.
OUTPUT
Adjusts the
final pro-
cessed output
level as seen
on the VU
meter.

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 230 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 rear panel. There is no “lock”
indicator per-se, but word clock lock is indi-
cated by the presence of digital audio at the
output. “No output means no lock.”
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
MIX
Adjusts the
strength
(boost) of the
Big Bottom
effect.
DE-ESS
THRESHOLD
Lets you set
the level
where you
want your
esses to level
off.
DE-ESSING
Shows when
the the de-
esser is work-
ing. When
the light is
on, sibilance
is being
controlled.
