APHEX switch beneath the input connection cover must be set to ON. Setting this

crisp and clear.
BASS andTREBLE Bass and treble controls are provided to adjust the high frequency and low frequency
response of the paging system. Reference positions are provided for these controls.
When set to these positions, the frequency response of the system will be flat. Set
the controls to the customer’s satisfaction. Clockwise rotation increases (boosts)
the response and counterclockwise reduces (cuts) the response. Increasing bass
and/or treble can cause output signal peaks to increase. Check the PEAK LEVEL
indicator after making bass adjustment and lower the music input volume if excess
peaking occurs.
