1176LN Controls
Input Adjusts the amount of gain reduction as well as the relative threshold. An In-
put value of ∞ (turned fully counterclockwise) yields no compression (and no
signal level). Rotate this control clockwise to increase the amount of compres-
sion.
Output Adjusts the output level (by up to 45 dB). Make sure to adjust the Output con-
trol after the desired amount of compression is achieved with the Input and At-
tack controls. To monitor the Output level, set the VU Meter to +8 or +4. The
Output control does not affect the amount of compression.
Attack Sets the amount of time (from 20–800 microseconds) that must elapse once
the input signal reaches the Threshold level before compression is applied.
Faster attack times are achieved by rotating the Attack control clockwise. The
faster the Attack, the more rapidly compression is applied to signals above
the threshold.
Release Sets the amount of time (from 50–1100 msec.) it takes for compression to
cease once the input signal drops below the threshold level. Faster release
times are achieved by rotating the Release control clockwise. Slower release
times can smooth the transition that occurs when the signal dips below the
threshold, especially useful for material with frequent peaks. However, if you
set too large of a Release time, compression for sections of audio with loud
signals may extend to lengthy sections of audio with lower signals.
Ratio These four pushbutton switches (to the left of the VU Meter) determine the com-
pression ratio. Ratios of 20:1, 12:1, 8:1, and 4:1 are provided. The 20:1
and 12:1 settings are typically used when peak-limiting is desired, while the
4:1 and 8:1 settings are used for general dynamic range compression.
