MUSIC VOLUME This control adjusts the level of the background music output. No reference level setting position is provided. The background music level should be set to an acceptable level without overdriving the system. When adjusting this level, the PEAK LEVEL indicator should be observed to ensure that the amplifier signal is not distorted.
MUSIC MUTE This control adjusts the level of the background music heard during a paging announcement. No reference level setting position is provided. The background music mute level should be set to the customer's satisfaction, but the page announcement must always be easily heard above the background music.
MIC VOLUME This control adjusts the level of the microphone page output. A reference level setting position is provided with this control. When set to this position, the output level of the page should be about maximum. Further adjustment can be made by observing the PEAK LEVEL indicator.
CAUTION: Microphone should not be placed near any paging loudspeakers.
RINGER VOLUME This control adjusts the level of the night ringer tone output. No reference level setting position is provided. The background music level should be set to the customer's satisfaction. When adjusting this level, the PEAK LEVEL indicator should be used to ensure that the amplifier signal is not distorted.
APHEX This control adjusts the amount of Aphex® Aural Exciter effect mixed in to the page signal. No reference position is provided for this feature. To use this function, the APHEX switch beneath the input connection cover must be set to ON. Setting this switch to OFF bypasses the Aphex effect and makes the control inoperable.With the APHEX switch turned on, make a page and rotate the control until the audio sounds crisp and clear.
BASS and TREBLE 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.
