master
This knob controls the main level of the alternate output.
PK/Sig LED
The After-Fader signal is shown as varying GREEN intensity, while the channel clip
warning illuminates RED.
AFL
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.
gain 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.
limiter
This knob sets the threshold level at which limiting begins. The corresponding LED
will illuminate when the established threshold has been exceeded.
compressor
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.
expander
This knob sets the threshold level at which downward expansion begins.
The corresponding LED will illuminate when the established threshold has
been exceeded. The ratio is preset to 1:2.
