(4) Meter - A standard VU meter that displays either the amount of gain reduction or output level for
the channel, depending upon the setting of the Meter Function switch. (

see #3 above)
Occasionally, one or both meters may require calibration. (

see page 23 for instructions for
calibrating the 2-1176 meters)
(5) Input - Determines the level of the signal entering the channel, as well as the threshold. Higher
settings will therefore result in increased amounts of limiting or compression.
(6) Output - Determines the final output level of signal leaving the channel. Once the desired amount
of limiting or compression is achieved with the use of the Input control, the Output control can be used
to make up any gain lost due to gain reduction. To set the desired output level, set the Meter Function
switch to +4 (

see #3 above) and then alter the Output knob as required.
(7) Ratio - This six-position switch determines the severity of the applied gain reduction for that
channel. (A ratio of 4:1, for example, means that whenever there is an increase of up to 4 decibels in
the loudness of the input signal, there will only be a 1 dB increase in output level, while a ratio of 8:1
means that any time there is an increase of up to 8 dB in the input signal, there will still only be a 1
dB increase in output level.) When higher ratios (12:1 or 20:1) are selected, the channel is limiting
instead of compressing. Note that higher Ratio settings also set the threshold higher. (

for more information)
The Ratio switch allows six different modes of operation for each channel of the 2-1176:
1 - Selects a 1:1 ratio (no compression).
4 - Selects a 4:1 ratio (moderate compression).
8 - Selects an 8:1 ratio (severe compression).
12 - Selects a 12:1 ratio (mild limiting).
20 - Selects a 20:1 ratio (hard limiting).
All - Implements the “All-button” or “4 button” mode (sometimes also known as “British
Mode”), in which the channel of the 2-1176 duplicates the overdrive that occurs when all four
ratio buttons on an original 1176 are pushed in simultaneously.


Setting the Ratio to 1 (1:1) disables compression altogether for that channel; however,
signal continues to pass through the channel’s circuitry. This is used to add the “color” of
the 2-1176 without any actual gain reduction. (The same effect is achieved when the 2-
1176 is placed in BYPASS mode. (

see #10 on the following page for more information)

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. (
