You might reasonably expect that the playback source such as a CD or tape player will no output level which would require compression, so you might not configure those inputs to participate in the output compression scheme. Threshold is the sensed output level above which the compressor begins to actuate. Release Time is the time in seconds to release compression at a slope of seconds per 10 dB. The range is 0.2 to 30 seconds for each output. The gate count feature attenuates all gated on inputs by a predetermined amount when more than one input is gated on. The purpose is to prevent feedback problems due to multiple open mics.
Amount is how much attenuation per additional open mic.
This feature is sometimes called a filibuster control because it can make the mixer work in a first come first served manner by limiting how many inputs may gate open simultaneously. The only parameter to set is the actual maximum number of open mics. The range is 1 to 6 with settings for each output. This involves both software and hardware setup and it also requires that the serial port of each mixer be dedicated to CLN use. Note that if an SMX mixer is going to be used on a CLN, that the SMX can not be used as a system interface.
