REAR PANEL
The Preamplifier Tuner’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
- Accepts input from external IR receptors. Connect 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 processed through a high pass filter to reduce audio below 80 Hz. Use these outputs for
small speakers or in a sub woofer / satellite system.
Note: these outputs are identical to the full 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.
Red RCA jacks
- right analog audio
White RCA jacks
- left analog audio
11. Antenna inputs
-
Connections for the AM and FM antennas.
