Operation
Front Panel Controls
AUX Level Control
Controls the AUX input level, which is bussed directly to the output. Aux signal bypasses gain riding.
Relative Gain Control
Sets the relative amount of gain maintained above the ambient level. Range is 1 dB to 24 dB of gain.
Ramp Speed Control
Sets the speed by which gain is increased/decreased to the signal once the ambient noise level is
above/below the threshold, from less than 1 dB/s (slow) to greater than 20 dB/s (fast).
Maximum Boost Control
Sets the maximum amount of gain. Range is 1 dB to 22 dB of gain.
Threshold Controls
Activity threshold is set just above typical operating level of the program material applied to the gain
processing stage of the ANS501. Ambient threshold adjusts the ambient noise input threshold from
64 dBspl to 112 dBspl.
Front Panel Switches and Indicators
