B&K p/n 12698 - Manual (Page 11)

REAR PANEL
The A/V System Controller’s back panel is organized into groups of inputs and outputs for audio and video as
shown below. See back of this manual for an enlarged view.
1. AC fuse holder - Holds the AC Line fuse. Replace only with 0.5 Amp / 250 Volt Fast Blow fuse.
2. AC input receptacle - For attaching the supplied AC power cord to the A/V System Controller.
3. RS-232 input (optional)- For future interface applications.
4. Zone audio outputs - Variable level output to your external amplifiers. Note: the zone 1 outputs are identical to
the surround left and right front outputs.
5. Serial number - B&K Components, Ltd. serial number of your unit.
6. Antenna inputs - Connections for the AM and FM antennas.
7. Line inputs - connections from your audio/video sources.
Red RCA jacks - right analog audio
White RCA jacks - left analog audio
Yellow RCA jacks - composite video
4 pin din jacks - S-video
8. Line level outputs - Fixed level outputs to an audio or video recorder.
9. Zone video outputs - Variable level outputs to your video monitors.
10. IR in - Accepts input from external IR receptors. Connect an IR repeater (“home run”) to IR IN for controlling
the A/V System Controller. This method of control is useful when the front IR receptor is blocked (for example, by
a cabinet door) or to control the A/V System Controller from another room. This input is typically used in place of
an emitter attached to the front panel.
11. Control outs - Outputs that allow you to remotely control external devices. (See “Making The Connection“).
12. Digital outputs - One optical and one 3.5 mm coaxial that carry digital information from the selected digital
input of the A/V System Controller out to digital recorders, personal computers, etc.
13. Surround outputs - Variable level outputs for driving external power amplifiers or powered speakers.
14. Digital inputs - Inputs used to connect a digital audio signal from your source to the A/V System Controller.
The incoming signal may be PCM, Dolby Digital (AC-3) or DTS (Reference 20 only).
