FEATURES

FET-EQUIPPED FM FRONT END

The FET-equipped FM tuner front end results in excellent:
sensitivity, selectivity, signal-to-nojse ratio and'a remarkable:
freedom from cross-modulation distortion and spurious;
noise.

ADVANCED FM TUNER AND STEREO SEPA-~
RATION CIRCUITS

The FM IF stage is equipped with three le (integrated
circuits) and an equal number of solid state ceramic filters
for stable operation and maximum selectivity. The PM
MPX decoder (the part that separates the two channels of
FM stereo programs) operates according to the highly
accurate time switching principle and is provided with an
integrated circuit,

EFFECTIVE FM MUTING SWITCH

Unwanted, irritating inter-station noise on FM is eliminated
by the FM MUTING switch. This circuit, equipped with an
FET, also cuts out useless, too-weak FM station signals,
leaving only strong, high»quality stations to be received.

AM TUNER WITH SENSITIVE FERRITE
ANTENNA

To provide high reception sensitivity on AM, too, a_ferrite
loopstick antenna and a tuned RF amplifier circuit are
provided.

PRECISION-ENGINEERED AMPLIFIER
CIRCUITS

The audio amplifier is characterized by its extremely wide
frequency response, its great power bandwidth, its low
distortion figures and superb signal-to-noise ratio. It is
exclusively equipped with low-noise silicon transistors.

FULL CHOICE OF PROGRAM SOURCES

All standard program sources can be connected, including
two turntables, two tape decks, and an auxiliary sound
source as well as a microphone.

TAPE-TO-TAPE DUPLICATING POSSIBLE

With the help of two (open reel or cassette) tape decks,
copies of tapes can be made easily.

UP TO THREE PAIRS OF LOUDSPEAKERS

For easy comparison of speaker systems, or for main/re-
mote speaker installations, up to three pairs of speakers can
be connected and operated individually or A+B, A+C.

VERSATILE AUXILIARY CIRCUITS

These include cl ick-stop tone controls, low and high filters
for reducing noise, a loudness switch for more natural
frequency response at low volume levels, a stereo/mono
mode switch, and a signal strength meter for easy tuning.

DESIGN MATCHED TO OTHER PIONEER HI-FI
COMPONENTS

The modernistic, unobtrusively elegant design with metallic
front panel, large station dial and natural wood cabinet is
perfectly matched to that of other PIONEER hi-fi com-
ponents, permitting a total stereo system of uniform
attractiveness to be assembled.

LINE VOLTAGE AND FUSE

The SX-626 is available in two models: one model
operates only on 120V, and the other operates on
one of the five line voltages; 110V, 120V, 130V,
220V and 240V. If your SX-626 is the latter
model, set the unit to the proper line voltage by
following the procedure described below.

CHANGING LINE VOLTAGE SETTING AND
FUSE

To remove the fuse, turn the fuse cap located on
the line voltage selector in the direction of the
arrow.

Then remove the fuse plug from the unit. Put the
fuse plug back so that the proper line voltage mark-
ing can be seen through the cut in the edge of the
plug. Whenever the position of the selector is
changed, check the rating of the fuse. A 1A fuse
is to be used for either 220V or 240V operation
and a 2A fuse for 110V, 120V or 130V operation.
If the rating of the fuse is correct, replace cap.

FUSE REPLACEMENT

When the fuse blows, remove the fuse cap and re-
place the fuse with a new one. See Fig. 1.
