HB-2PA ‘DUCK’ Override initiates an automatic ‘DUCK’ of the HNB-B

audio sources (B+C on Front) and is adjustable from 0dB to -50dB (Off) at

10ms attack time when signal is detected and releases at 3-5 seconds

when signal is removed. This is an internal screwdriver manual ‘POT’

adjustment on the HB-2PA and is not normally end-user accessible.

Note: When the internal audio line input is activated and ‘Voltage Present’ is

detected, all audio sources (B + C) to HB-2PA are immediately ‘DUCKED’

to the amp and speakers. The audio line signal routes to the amp and is

broadcast to speakers ‘ON TOP’ of the original audio source. The input

audio level IS ADJUSTABLE and can be set different than the original

source material.
