REAR PANEL

The Pream plifier T uner’s back panel is organized into groups of inputs and outputs as shown below. See back of
this manual for an enlarged view.
1. Serial number - B&K Components, Ltd. serial number of your unit.
2. AC input receptacle - For attaching the supplied AC power cord to the Preamplifier Tuner.
3. RS232 input - Optional RS232 software is available to allow for enhanced system control and interface.
4. Control out - Output that allows you to remotely control external devices. (See “Making The Connection“).
5. IR in - Acc epts input from external IR receptors . Connec t an IR repeater (“home run”) to IR IN for controlling the
Preamplifier Tuner. This method of control is useful when the front IR receptor is blocked (for example, by a
cabinet door) or to control the Preamplifier Tuner from another room. This input is typically used in place of an
emitter attached to the front panel.
6. MONO L+R and SUB PREAMP outputs - Variable level outputs for driving external power amplifiers or
powered speakers. Mono is the summation of the L+R full range audio signals that is then processed by a
low-pass filter to reduce audio above 80 Hz to source the SUB output.
7. HIGH PASS outputs - Variable level outputs for driving external power amplifiers or powered speakers.
These outputs have been pr oces s ed through a high pas s f ilter to reduc e audio below 80 Hz. Use these outputs f or
sm all speak ers or in a sub woofer / satellite system. Note: these outputs are identical to the f ull range outputs with
the addition of a 80 Hz 12 dB / Octave high-pass filter.
8. FULL RANGE PREAMP outputs - Variable level output to your external amplifiers.
9. TAPE inputs and outputs - Fixed level output for use with an audio recorder and a return for a tape monitor.
10. Line inputs - connections from your audio sources.

- right analog audio

White RCA jacks

- left analog audio
11. Antenna inputs - Connections for the AM and FM antennas.
