Controls
(1) LIMIT/COMPRESS switch affects the
compression ratio, going from a fixed
compression ratio in Compress mode,
and shifting to a near-infinite ratio in
Limit mode.
(2) PRE-EMPHASIS trimmer adjusts the
sidechain that the compressor responds
to, but does not affect the audio directly in
any way. Set fully clockwise to the 'Default'
position, the sidechain responds to the full
frequency bandwidth of the incoming audio.
As the trimmer is turned counterclockwise,
the compressor responds less to low
frequency transients.
(3) OUTPUT GAIN knob sets the overall level sent
from the unit.
(4) VU METER displays either the amount of gain
reduction or the output level, depending on
which operation is selected.
(5) PEAK REDUCTION knob controls the
threshold of the compressor/limiter.
A maximum of 40 dB gain reduction is
available, which is likely more than any
practical scenario would require unless used
in a parallel compression setup.
(6) METER SELECT knob determines whether
the VU Meter displays the amount of gain
reduction or the output level. When set to
output level mode, a meter reading of 0 dB
corresponds to an output level of +4 or
+10 dBu, depending on the selection.
(7) POWER switch turns the unit on and off.
The LED will light to indicate the unit is
powered on.
(8) METER CALIBRATION knob allows the meter
to be adjusted for accuracy by following
these steps:
• Disconnect any audio cables from the
rear panel, then turn the unit on
• Select 'Reduction' on the Meter Select knob
• Adjust the calibration knob until the meter
reads 0 dB

Quick Start Guide
(9) STEREO LINK allows a pair of 2A-KT
units to be connected via standard
¼" TRS cable, sharing the threshold
response between them by blending the
sidechain signals. The front panel controls
should still be set the same between the
2 units, and the output levels should be
carefully balanced. To calibrate the stereo
balance, follow these steps:
• Connect the units with a short ¼" TRS
shielded cable
• Turn the Peak Reduction knob fully
counterclockwise
• Set both Meter Select knobs to show
gain reduction
• Turn both Stereo Link trimmers to the
Default setting
• Play a mono test signal into both
units simultaneously, and turn the
Peak Reduction knobs up on both units
until gain reduction registers on the meter.
Set the Peak Reduction knobs identically,
and the meters should show very similar
response to one another.
• If one unit shows more reduction
than the other, turn that unit's Stereo Link
trimmer clockwise until the meters match.
