2. GATE SC HPF/LPF: indicates & adjusts the high pass and
low pass lters of the gate side chain to allow more accurate
gating of signals.
3. GATE DEPTH: indicates and adjusts how many dB of
attenuation the gate will apply when it is closed.
4. GATE THRESHOLD: indicates and adjusts the threshold of the
gate opening/closing.
5. OPEN/HOLD/CLOSED indicators: indicate the operation of
the gate:
OPEN = gate is passing signal and audio is above the

2. COMPRESSOR GAIN: indicates and adjusts the gain of
the compressor, is used to ‘make-up’ gain lost through
compression of the signal.
3. COMPRESSOR RATIO: indicates and adjusts the compression
ratio within the compressor.
4. COMPRESSOR THRESHOLD: indicates and adjusts the
threshold of the compressor.
5. GAIN REDUCTION INDICATOR: indicates the amount of dB
attenuation applied by the compressor.
6. COMP key: toggles the compressor IN/OUT; illuminates when
