Control Output / Amp Enable
The Control Out and Amp Enable outputs are standard 1/8” mono mini-jack connections used for triggering such pieces as amplifiers,
screens, relays, etc. The output is a 100mA 5-24 VDC signal. The amp enabled output is active when the receiver is taken out of the
sleep/standby mode. The control output is active when the IR, RS-232 or Ethernet command is sent to enable the 12VDC signal. It is
disabled when the IR, RS-232 or Ethernet command is sent to disable the 12 VDC signal. Shown is the amp enable connection going
to the trigger input on an amplifier.
Control Input
One control input trigger is provided that may be used for theater events such as land-line telephone and doorbell notification. The con-
trol input trigger on the AVR 707 allows up to 24VAC or DC voltage sensing. Referred to as Page / Events, typical applications might
involve a doorbell and front door security camera. For example, when the doorbell is pressed, the AVR 707 could switch to a specific
A/V source input connected to a camera. The user may specify the duration and on screen message as part of the Page/Event. Wiring
diagrams for specific applications are available through B&K. Please see www.bkcomp.com or contact our Customer Service
Department for other specific applications.
AM / FM Antenna
The B&K receiver contains one internal AM/FM tuner. To connect the AM antenna, use the AM antenna connection block and the AM
antenna supplied. The AM connector is a ‘push pin type’ connection. Strip 1/4 inch of insulation off your AM antenna wires and insert one
wire end into each hole while holding the tabs down. Release the tabs to lock in the AM antenna wires. The FM connection is a stan-
dard screw F-type connector. Simply connect the supplied FM dipole antenna to this connection and route the leads for best reception.
Restore
Pushing in the restore button will reset all functions on the AVR 707. This feature is not active at this time.
