1176LN Solid-State Limiting Amplifier
The 1176LN is known for bringing out the presence and color of audio sig-
nals, adding brightness and clarity to vocals, and "bite" to drums and guitar.

tion section. Before the signal is applied to the Gain Reduction section, the au-
dio signal is attenuated by the Input stage. The amount of attenuation is con-
trolled by the input control potentiometer. The amount of gain reduction as
well as the compressor Attack and Release times are controlled by the Gain
Reduction Control circuit. After Gain Reduction a pre-amp is use to increase
the signal level. The Output Control potentiometer is then used to control the
amount of drive that is applied to the output amplifier. The 1176LN is a feed-
back style compressor since the signal level is sensed after the gain reduction
is applied to the signal.
