B&K 5 S2 ユーザーズマニュアル
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

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.

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.
