When this switch is depressed, the stereo after-fader signal is sent to the monitoring system. The channel LED is illuminated RED to indicate that the AFL is active.

88gain reduction metering

This meter array indicates the amount of gain reduction being applied to the alter- nate ouput. It indicates compressor, expander, and limiting activity. The source of the gain reduction can be determined by examining the expander and limiter’s LEDs. The one that is lit, is the source. If neither is lit, it is the compressor that is active.

The HPW’s alternate outputs are equipped with full featured compressors

Gain - This knob controls the amount of make up gain applied to the alternate out- put.

Ratio - This knob controls the slope of the compression. At fully clockwise (∞), the compressor acts as a limiter. Compression is effectively disabled when set to 1:1.

Threshold - When the signal exceeds the level set by this control, it is attenuated by the amount set by the ratio control.
