Kenwood KR-6340

1. The KR-6340 can function as a two or four channel receiver. It
has a built-in RM type (regular matrix), and SQ type decoders so
that it is capable of reproducing both RM and SQ encoded discs,
tapes and FM broadcasts in brilliant quadraphonic sound through
four speakers. The RM decoder enhances conventional stereo
programs by decoding the ambience found in most stereo programs
and applying it to the rear speakers. This receiver can also
reproduce discrete 4-channel tapes, and CD-4 discrete discs too,
in conjunction with the CD-4 demodulator KCD-2 (optional) which
can be simply plugged into it.
2. The KR-6340 has four amplifiers. As a 4-channel receiver these
amplifiers are made to work separately, each driving one of the
four speakers when the AMP CONTROL switch (rear panel) is set
to 4CH position. Power per channel is then 15 watts into 8 ohms
at 20 - 20,000 Hz.
As a 2-channel receiver, the amplifiers are made to work in pairs
and are capable of driving 40 watts per channel into 8 ohms at
20 - 20,000 Hz, when the AMP CONTROL switch is set to 2CH.
3. The semi·complementary directly coupled power amplifiers have
wideband and low distortion characteristics which ensure smooth,
high fidelity amplification.
4. Tone, Balance and Volume controls are designed to permit fine
adjustments of 4-channel sound to suit various program sources
and listening conditions.
5. Two pairs of speakers connecting terminals are available to permit
simultaneous listening at two different places.
6. A Double Switching Demodulator (DSD) is used in the MPX section.
This DSD method is used to prevent carrier leaks and ensure best
sound quality.
7. Interstation Muting circuit suprresses,interstation noise.
8. This receiver is equipped with FM Detector Output jack to enable
reception of FM discrete 4-channel broadcasts when this becomes
