Adjusts reaction time of the compressor after the signal crosses the
threshold. Unlike most compressors, you rotate this control clockwise for
faster attack (as with the original hardware).
Note: For DYNA and OPTA LA-2A compressor effects, the footswitch LED for
the selected Comp blinks rapidly when Attack is rotated, indicating the knob
has no effect.
Ratio
Adjusts the amount of compression of the signal after it passes the threshold.
This works differently for each compressor type, and is not used on the DYNA
compressor effect.
• DYNA – Unused. The footswitch LED for the Comp blinks rapidly when
Ratio is rotated, indicating the knob has no effect.
• OPTO LA-2A – Adjusts the compression ratio. The original hardware had
only two ratios, controlled by the COMP/LIMIT switch. We’ve added more
compression ratios for greater flexibility. Set this control to 4:1 to match the
COMP setting on the original hardware. Set this control to 20:1 to match the
LIMIT mode settings on the original hardware (the ALL setting is the same
as the 20:1 setting). Set to OFF for circuit color without compression.
• FET 1176 – Adjusts the compression ratio from 4:1 to 20:1. Set to ALL for
the unique “all buttons in” response. Set to OFF for circuit color without
compression.
Release
Adjusts how long it takes for the compressor to let the signal return to
normal after compression. This works differently for each compressor effect,
and is not used on the DYNA compressor effect.
• DYNA – Unused.The footswitch LED for the Comp blinks rapidly when
Release is rotated, indicating the knob has no effect.
• OPTO LA-2A – The original hardware has no release time control. We’ve
added release settings for greater flexibility. Set at noon to match original
hardware. Rotate clockwise for faster release.
