11
EXT KEY switch with yellow LED: Enables the external key signal via the EXT KEY input jack, which replaces the
incoming compressor signal as the source feed for the side chain. The side chain circuits control the gain reduction.
12
BYPASS switch with red LED: Enables a bypass condition whereby the VCA remains in-circuit, fixed at unity gain.
The gain reduction meter continues to operate with BYPASS enabled.
13
GATE switch with green LED: This switch selects channel operation as compressor mode (switch = disabled) or
gate mode (switch = enabled).
14
SIDE CHAIN FREQUENCY control knob: Selects the frequency at which the band pass filter acts on the side chain
signals, see Item 8 above. The filter can be used to make the compression frequency selective. Additionally, there is a solo
function (see Item 10 above) that places the filtered side chain onto the compressor’s solo bus output or, optionally, the
main output (SIP mode).
15
ATTEN DEPTH meter (dB): Dedicated attenuation depth (gain reduction) meter that displays the amount of
attenuation being applied by the compressor or gate, depending on which mode is selected. The meter comprises 10 LEDs,
scaled from -2dB to -20dB in 2dB increments. The compressor gain control will not affect the gain reduction meter reading.
16
HARD KNEE switch: Used in combination with the VINTAGE switch to provide four compressor operating modes,
see “Compressor” on page 19.
17
VINTAGE switches: See HARD KNEE above.
18
GATE HOLD control knob: Minimises chattering in conjunction with internal hysteresis, see “Intelligent threshold
shift (i-TS)” on page 29. Once the signal is detected as below threshold, this control defines a waiting period before the
gate starts to close.
19
ATTACK control knob: Adjusts the time it takes the compressor to respond or the gate to open after an over
threshold signal, depending on which is selected.
20
LINK switch with yellow LED: Each adjacent pair of channels has an intermediate LINK switch that, when
enabled links them together, see “Stereo and multiple channel operation - linking” on page 17.
