The SM-5200H and SM-SZDOHB are quite the same except for the Panel and
knobs different in color between them,

So, this Service Manual is prepared refering to the SM-SZOOH alone: the
difference of the SM-SZOOHB against it can be made out with a reference to

FEATURES

DISTORTION-FREE POWER AMPLIFIER

The differential amplifier and direct coupled complementary
OCL circuitry in the amplifier stages provide broad band
power with minimum distortion.

EOUALIZER WITH DUAL POWER SUPPLY

[CL equalizer amplifier includes a dual power supply system
(plus 15\/ and minus 15V) to improve the signal-to»noise
ratio, assuring a greater dynamic range,

NF TYPE TONE CONTROL

Bass and treble controls permit a wide variety of tone control
and allow sound to be adjusted to personal taste and room
acoustics.

TAPE DUBBING -
Tape dubbing from Tape 2 to "Tape 1" is possible, with
the connection of two separate tape decks.

SUBSONIC FILTER
6dB octave filter effectively reduce unwanted noise at low
end of the sound spectrum.

DUAL SPEAKER OUTPUTS

Connections are provided for two separate pairs of speakers
with front mounted control for separate or combined op-
eration.
