Output
The Output control determines the final output level from the 1176LN. Once the desired
amount of limiting is adjusted by setting the Input Control, the Output Control can be
used to set the required output level. Set the Meter switch to the Compressor (COMP)
position so that the meter reads the desired output level from the 1176LN.
Attack
The Attack control adjusts the time it takes the limiter to respond to an input signal and
instigate gain reduction. The Attack control allows for an adjustable response time of 20-
800 microseconds. The fastest attack time is achieved when the Attack Control is in its
fully CW position. The Attack knob is also a redundant “Compressor Off” control. See
Compression Ratio 1: below.
Release
The Release control allows for an adjustable release time of 50 to 1100 milliseconds.
The fastest release time is achieved when the control is in the fully CW position.
Compression Ratio
The Ratio control allows 7 different modes of operation.
BP: Bypass. This position switches the 610B output directly to the 1176LN output.
In this position the 1176LN and its associated “tone” are completely removed from the
signal chain. This feature is here so you can quickly remove the Limiter from the signal
path without having to physically move cables.
1: This position passes signal through the 1176LN with NO GAIN REDUCTION.
(This is the same as turning the Attack knob full CCW until it clicks OFF).
A common use of the 1176 for adding “color” without compression.
4: This position selects a 4:1 compression ratio.
8: This position selects an 8:1 compression ratio.
12: This position selects a 12:1 ratio (mild limiting).
20: This position selects a 20:1 ratio (hard limiting).
All: This position implements the “4 button trick”. This mode increases distortion and the
Meter goes wild, often maxing out. This is what happens when all 4 ratio push buttons on
an original 1176 are pushed in. Also know as “British Mode”.
