Timeout Interval
All outputs return to default volume after a period of
inactivity (the timeout interval). The timeout interval is
set by the TIMEOUT dial, in increments of 15 seconds.
If the timeout switch is set to 0, the demonstration does
not time out. Each time a customer adjusts volume the
timeout resets. Default volume may be adjusted from
low (0) to high (9) volume level.
Audio Bus Out
The audio BUS OUTPUT feeds the currently selected audio input (MUSIC
PLAYER) to more 1714 modules in the system. Do not connect headphones to
this output. Connect a 3.5mm patch cord from the rst 1714 bus output to the
second 1714 player input, etc.
Power
Connect included 12V power supply to Power Input. Connect jumper to other
1714 units if desired.
Operation
On power up, the POWER light comes on to show normal operation. VOLUME
DOWN/UP buttons (if installed) light up when pressed and released. Press
VOLUME DOWN/UP to control volume. Rotary VOLUME knob increases volume
with clockwise rotation, push in function selects mute/un-mute. Rotating the knob
also un-mutes the audio.
