SENSITIVE FM TUNER SECTION

The SX-525 uses modern solid state circuitry throughout its
sensitive FM front end to give you superb FM reception and
tonal quality. An FET (field effect transistor) is used in the front
end to raise sensitivity and image ration while helping to prevent
against irritating cross-modulation. The IF stretch of the front
end is equipped with IC (integrated circuit) and ceramic filters
to improve selectivity and capture ratio. Additionally, a switch-
ing type stereo demodulator is used to ensure fine separation
over the very wide frequency range, while a discriminator am-
plifier assures sharp channel separation.

EFFECTIVE FM MUTING SWITCH

To eliminate undesirable, irritating inter-station noise on FM,
the SX-525 is equipped with an FM muting switch. This circuit
is also equipped with an FET and cuts out useless, too-weak
FM station signals, leaving you with only the sound of high-

LARGE TUNING METER AND LINEAR DIAL SCALE

Station tuning is easier than ever with Pioneer's large tuning
meter and wide linear FM dial scale. The tuning meter is
especially significant in helping to achieve maximum channel
separation and tone quality. The linear dial scale is ideal for
achieving perfect reception and minimum noise and distortion.

SUPREME VERSATILITY

You have a full choice of program sources with the SX-525. All
standard program sources can be connected, iecluding two
turntables, two tape decks --reel to reel or cassette-, an auxiliary
sound source as well as a microphone. Up to two pairs of
speakers can be connected and operated individually or simul-
taneously with the SX-525 to permit easy comparison of speaker
systems or remote speaker installations.
