Operation
IMPORTANT: Before plugging the amplifier into an AC outlet, turn all volume
controls to their full counterclockwise positions.
POWER IND The POWER IND LED illuminates whenever AC power is applied to the amplifier
(there is no power switch on the amplifier).
PEAK LEVEL The PEAK LEVEL LED illuminates whenever the speaker output signal level
approaches its maximum level. This indicator is used when setting volume levels.
Maximum output level is achieved when the PEAK LEVEL indicator flashes
intermittently on loud peaks of the input signal. If the indicator illuminates steadily,
the output signal volume is set too high and distortion is occurring. Decrease the
volume control for the appropriate input until the indicator flashes only
occassionally.
TEL VOLUME This control adjusts the level of the telephone page output. Further adjustment can
be made using the PEAK LEVEL indicator described above.
MUSIC VOLUME This control adjusts the level of the background music output.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. 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.
CAUTION: Microphone should not be placed near any paging loudspeakers.
RINGER VOLUME This control adjusts the level of the night ringer tone output.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. 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.
