FACILITY USAGE or FUNCTION
Audio gain Sets the level of amplification of incoming signal. Influenced by no other adjustment
Chime level Determines the level of chime tone to be injected. Influenced by no other adjustment
VOX sensitivity Sets level of audio input at which the VOX circuit is triggered. Influenced by ‘Audio gain’.
Temporarily set sensitivity to maximum, and set Vox delay to maximum to enable ‘Audio level’ to
be set using typical input signal, then reset ‘VOX sensitivity’ and then ‘VOX delay’.
VOX delay Determines the time delay between cessation of audio input signal and release of priority and/or
muting of channel. Influenced by Audio gain and VOX sensitivity. Adjust those first.
Chime frequency Sets collective pitch of chime sequence. Tones may not be adjusted individually. Influenced by
no other adjustments.
Bass cut link Cut this link to introduce a sensitivity roll-off at bass frequencies. Particularlyeffective for paging
applications.
Sensitivity link Cut link to change the scope of Audio gain adjustment to 50mV-2V, from 2V-80V RMS.
Priority/passive jumpers See relevant information on page 12
Timer duration Sets period of on-board timer within the range 2-30 seconds, after which the priority is released
and tone ceases. Influenced by no other adjustments.
Output level Sets level of audio tone output from module. Influenced by no other adjustment.
Tone generator frequency Sets audio pitch of tone generation sequence. Influenced by no other adjustments.
