(8) LINK / DUAL switch - Sets the 2-1176 to either dual mono or stereo linked operation. When set to
the down (DUAL) position, the 2-1176 operates as two separate compressors, with the two channels
operating completely independent of one another. When set to the up (LINK) position, the two channels
of the 2-1176 act as a single stereo compressor, with equal gain reduction on both sides, even when
there is transient activity only on one channel. (

(9) Power - Turns the 2-1176 power on or off. When powered on, the purple LED immediately above the
switch lights up.
(10) BYPASS / COMP switch - Allows a comparison between the compressed signal and the non-
compressed signal. However, regardless of the position of this switch, signal continues to pass
through the 2-1176 circuitry (thus picking up the signature 2-1176 sound) and the Input and Output
knobs remain active. When in the up (BYPASS) position, a ratio of 1 (1:1, or no compression) is applied
to both channels of the 2-1176 regardless of the setting of their Ratio switches. When in the down
(COMP) position, the selected Ratio for each channel is applied.

When a Ratio of ALL is selected, distortion increases radically due to a lag time on the
attack of initial transients and there are constant changes in the attack and release times,
as well as a change in the bias points. Consequently, the meter will go wild, often resting at
maximum.

Engineers typically use the ALL Ratio on drums or on ambience or room mics. It can also be
used to “dirty” up a bass or guitar sound, or for putting vocals “in your face.”


When operating the 2-1176 in LINK mode, the Input and Output knobs should normally be
set to the same position in both channels. (


The BYPASS / COMP switch setting always affects both channels of the 2-1176,
regardless of the LINK / DUAL switch setting.

When operating the 2-1176 in LINK mode, the left channel’s Attack and Release knobs
affect both channels and the right channel’s Attack and Release controls become
non-functional. (


In order to obtain a specific amount of limiting or compression for each channel of the
2-1176, begin by setting both the Input and Output knobs to approximately “5” (their
12 o’clock positions) for unity gain. Set the Ratio as desired, then set the Attack and
Release controls to approximately “5” (their 12 o’clock positions) so that some gain
reduction is enabled. Set the Meter switch to GR so that the meter shows the amount of
gain reduction, then slowly turn the Input control up until the desired amount of gain
reduction is achieved. Finally, adjust the Attack and Release times until they are suitable
for the program material and make up any gain necessary by raising the Output knob
(set the Meter switch to +4 in order to have the meter display the final output level).
