FEATURES

Power Amplifier

The SA-8500 employs high reliability NPN & PNP silicon
power transistors. Together with the differential first stage,
all stages are direct coupled in a pure complementary OCL
circuit configuration. Careful circuit design and selection of
components results in a wide output bandwidth.

Extremely Close RIAA Equalization

RIAA deviation, which governs record playback fidelity,
is reduced to very close tolerance by stringently selected
equalizer elements. A dual DC power supply system is also
employed to provide increased acceptable input volume,
resulting in expanded dynamic range and faithful record
performance at low distortion. The PHONO 2 jacks are
equipped with a convenient level control. This permits the
level to be adjusted to match that of the cartridge con-
nected to the PHONO l jacks.

Capable of Delicate Tone Adjustments

PIONEER developed twin tone control circuits are applied
to conventional BASS and TREBLE controls. Independent
controls are provided for ultra low and ultra high fre-
quencies, allowing fine tone adjustments to be performed
according to room acoustics or cartridge frequency charac-
teristics. A TONE switch is also included to permit com-
paring the effectiveness of the tone controls.

Protection Circuit

Electronic circuitry and a relay are combined in a fast
action protection circuit which guards transistors and
speakers from damage in the event of defective connecv
tions, such as speaker terminal shorting. When DC current
appears in the output, the output circuit is instantly
opened. The protection circuit also performs a muting
function when the power switch is operated.

Program Sources which can be Enjoyed

Stereo input iacks are provided on the rear panel for two
turntables, two tape decks, a tuner, an auxiliary program
source plus a microphone, allowing for great flexibility in
operation.

Easy Tape Duplication
By connecting two tape decks, the desired programs only
can be edited from a recorded tape. The convenient DUPLI-

CATE switch also allows duplication from open reel to
cassette tape formats.

Elegant Styling Complements Performance

The front panel of this new Pioneer stereo amplifier has
been designed to combine ease of operation with handsome
appearance.
