The Preamplifier Tuner's back panel is organized into groups of inputs and outputs as shown above.

1. AC Input Receptacle - For attaching the supplied AC power cord to the Preamplifier Tuner. The
serial number of your unit is located below the AC input receptacle. AC line fuse rating - .5A 250V

2. RS-232 - RS-232 Two Way communication allows enhanced system control and BKcSuite inter-
face.

3. IR output - IR signals received by your Preamplifier's front panel or the Infrared Data/Signal input
pin are repeated out this IR connector 1/8” (3.5mm) mono.

4. Control I/O - Allows connections to a zone keypad/IR sensor via a 5 pin plug-in Phoenix connector. Also
supplies a control voltage for an amplifier.

+12V

- +12VDC Power to Keypad or IR Sensor

Ground

- Common Ground

RS-232 Xmit

- RS-232 One Way Transmit Out

Data In

- Infrared Data Input

CTRL Out

- 12VDC Programmable Control Out

5. FULL RANGE Balanced (XLR) output - Variable preamp outputs for driving an external power
amplifier.

Pin 1 - ground
Pin 2 - POS +
Pin 3 - NEG -

6. MONO L+R and SUB PREAMP (RCA) outputs - Variable level outputs for driving external power
amplifiers or powered speakers. Mono is the summation of the L+R full range audio signals. It is then
processed by a low-pass filter to reduce audio above 80 Hz to source the SUB output.

7. HIGH PASS (RCA) output - Variable preamp outputs for driving external power amplifiers or pow-
ered 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 subwoofer / satellite system. Note: these outputs
are identical to the full range outputs with the addition of an 80 Hz 12 dB / Octave high-pass filter.

8. FULL RANGE (RCA) output - Variable preamp outputs for driving external power amplifiers.

9. TAPE inputs and output - Line level input and fixed output for use with an audio recorder. Tape
Output supplies a return loop for the source input selected.

10. Source line inputs - Left and right 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.
