Headphone Jack - Headphones having a standard 1/4” stereo plug may be connected to the headphone output.
7
Control Output - 1/8” Mono Mini-jack (Tip+ Ring -) source of 12VDC 100mA output for controlling external devices, such as ampli-
fiers and projection screens. A remote control CTRL+ "Control On" command will turn on 12VDC and “CTRL-” will turn off 12VDC.
Additional control and control is available using RS-232 and Ethernet BKC-DIP.
Amp Enable - 1/8” Mono Mini-jack (Tip+ Ring -) source of 12VDC 100mA for use with automatically controlling an external device
while not in standby.

Restore - Sometimes it is advisable to restore the unit to a factory default state in order to clear problematic system operation. A
factory restore will clear all system settings, Audio and Video Preferences and Serial Macros. Restore may be selected by simulta-
neously pressing the front panel Sleep, Up and Right Encoder Knob [Master Volume]. alternately, pushing in the rear panel button
for 5 seconds will restore all settings to factory default.
9
USB 2.0 - USB 2.0 connection for use of configuring and controlling the receiver. Feature is not enabled at this time. Please see
for updates, when available.
10 RS-232 Control Port - RS-232 RJ-45 input/output for computer interface and RS-232 serial controller applications.
Ethernet Control Port - Ethernet RJ-45 input for flashing the software in the receiver. Also used for computer interface and Ethernet
control applications.
11
FM/AM Tuner - Respective connections for attaching the included AM and FM tuner antennas for internal tuner reception.
12 Coax Digital Audio Inputs - A total of 8 coax digital audio inputs for connecting coax digital audio signals from the source to the
receiver.
Coax Digital Audio Output - A single coax digital audio output for use with another audio device. The audio output is currently
sourced from the selected audio input..
13 RCA Surround Outputs - 7.1 Surround outputs for driving external power amplifiers or powered speakers.
14 RCA Analog Audio Inputs - A total of 8 stereo analog RCA inputs for use as standard input pairs. Optional Multi-Channel analog
support for use with inputs 5-7 (5.1), 5-8 (7.1). Configuration may be set and viewed using the menu or BKcSuite.
RCA Analog Record Output - A stereo pair of analog RCA outputs for use with an analog recording device.
15 Digital Optical Audio Inputs - A total of 8 optical digital audio inputs for connecting optical digital audio signals from the source to
the receiver.
Digital Optical Audio Output - A single optical digital audio output for use with another audio device. The audio output is current-
ly sourced from the selected audio input.
16 Component Video Inputs - A total of 8 component video inputs for standard and high definition video signals. Composite video
directly connects to the red RCA. S-Video is Y - green RCA, C - blue RCA using supplied S-VIDEO to RCA adapter.
Component Video Outputs - Scaled video output may be set to 720p, 1080i - default set to 1080i.
17 AVR 705 Speaker Outputs - 5-Way binding posts supply power to the Front, Surround and Center channel speakers.
18 AVR 707 Speaker Outputs - 5-Way binding posts supply power to the Front, Surround, Center and Back channel speakers.
19 IR Flashers, All IR Output and IR In - 1/8" Mini-Jack (Tip + Ring -) connections for IR routing. Flasher outputs allow routing of up
to 14 source components. All IR Output will direct all IR information being received by the unit from the Keypad input, front panel or
the 1/8" Mini-Jack IR input. IR Input allows an IR signal to be sent into the unit in order to control the receiver or for routed pass-
thru control of a connected source component.
20 Keypad Connection and IR Daisy Chaining - RJ-45 Keypad Connection provides a 12VDC power, common ground, RS-232
transmit, IR Data IN, and 12V control output trigger. The receiver will support up to 5 daisy-chained B&K keypads. The IR Chain con-
nection allows linking the receiver to a CT product for full two-way communication.
21 Three-position Phoenix Adapter - Phoenix connection for using a Page / Event system with the receiver. Feature is not enabled
at this time. Please see for updates, when available.
22 HDMI Inputs/Output - 6 input and 1 output High Definition Multimedia Interface (HDMI) connections. Connections carry both the
digital audio and digital video signal simultaneously with output resolutions of 720p, 1080i or 1080p - default set to 1080i.
23 AC Input Receptacle - For attaching the supplied AC power cord to the unit.
24 AC Fuse Holder - Holds the AC line fuse. Replace only with same type and value 12A fast blow. Note: The voltage rating label is
located on the AC fuse holder cover plate.
