Timeout Interval
The demo timer is initiated each time a customer selects a product output to
audition. The demonstration length is set by the timeout switch, in 15 second
increments. If the switch is set to 0, then the automatic demonstration timeout
feature is disabled. After the timeout expires, all outputs are de-selected and the
volume is reset.
Power
Connect included 12V power supply to Power Input. Connect jumper to other
1715 units if desired, up to four units total.
How to Set the Gain Control
• Raise the volume controls (on the player and/or 1715) to
maximum.
• Connect a pair of headphones to the 1715 that has similar
impedance and sensitivity to the range of headphones you
wish to demonstrate.
• Turn the 1715 Gain dial (see chart below) to 1 and start the music player.
• Select a headphone position, and raise the 1715 Gain dial to the point of
distortion, then adjust it down to the desired maximum level.

Theft Detection
1715 theft detection (off by default) is compatible with most headphone models,
including models with active circuitry such as noise cancelling. Activate theft
detection using the Theft Detect switches. All devices should be tested for
proper detection behavior upon installation. If detection does not work for a
particular device, disable detection for that port. For more information go to www.
audioauthority.com/product_details/1715.
Operation
On power up, the status light blinks to show normal operation. Press a product
select button to demo headphones. The default volume level is a percentage of
the maximum, relative to the Gain setting. When the Customer Input is being
used, the Status light blinks rapidly. If used, the 1795 volume control light ring
pulses in attract mode and indicates volume levels during a demo.
