goes into limiting. With the Link switch out, Channels A and B oper- ate independently as two monophonic compressor/limiters.

With the Link switch in, Channel A's controls become master controls for Channels A and B, with the exception of the input/output and the +4 dBu/-10 dBV switches which will continue to operate indepen- dently. The stereo signal is processed identically by both channels to preserve proper stereo imaging.

While in stereo mode, the compressor and gate control signals are derived from a combination of Channel A and Channel B inputs. Compression and gating are not soley dependent upon the input signal present at Channel A (the master channel). For example, an input sig- nal on either Channel A or Channel B will cause compression to occur (and/or open both gates) once it rises above the threshold set by Channel A controls, even if there is no input signal present on the op- posite channel.

For stereo sidechain applications, please refer to Section 1.8.

NOISE GATE CONTROLS

The noise gate will not pass signals below the specified threshold set- ting, but signals above the threshold will pass unaffected. In a typical application, the threshold would be set just above any residual hiss or noise. Thus with no signal going through the 3630, no hiss would be audible. A signal going through the 3630 would pass through unim- peded. The hiss would also be present under these conditions, but since a strong signal is present it would tend to "mask" the hiss.

To use the 3630 solely as a noise gate, set the Ratio control to 1:1. This passes the input signal to the noise gate without processing.

Threshold (no gating to -10dBV)

Sets the level above which the noise gate will allow signals to pass. Turning the Threshold fully counter-clockwise disables the noise gate and lets the signal through unaltered.

To set the proper gate level for most applications, turn the Gate
