FEATURES

SENSITIVE 8i HIGHLY SELECTIVE FM STEREO

TUNER

The tuner circuits are equipped with a two-stage RF ampli-
fier, selected PET and transistor in the front end, resulting
in very linear amplification irrespective of incoming signal
strength. Therefore no cross-modulation or spurious radia-
tion interference. Moreover, ceramic filters in the IF stage
and a newly developed IC in the FM IF stretch give very
high selectivity, capture ratio and limiting effect. Clean FM
reception even in fringe or station-crowded areas. Antenna
terminals for 30052 feeder and 7552 coaxial cable.

OCL (OUTPUT-CAPACITOR-LESS), PURE COM-
PLEMENTARY POWER AMPLIFIER

A revolutionary design principle using PNP and NPN silicon
power transistors for highest sound purity and absence of
distortions. Balanced (+) and (-I power supply and direct
coupling of all amplifier stages, therefore extremely wide
frequency response down to sub-audio range.

FULL CHOICE OR 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.

LINE VOLTAGE AND FUSE

The SX-727 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-7 27 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 1.5A fuse
is to be used for either 220V or 240V operation
and a 3A fuse for 110V, 120V or 130V operation.
If the rating of the fuse is correct, replace cap.

TAPE-TOTAPE DUPLICATING POSSIBLE

With the 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/remote
speaker installations, up to three pairs of speakers can be
connected and operated individually or A+B, A+C.

FULLY EOUIPPED WITH VERSATILE CON-
TROLS

Click-stop tonecontrols, separate for each channel. Low and
high noise filters, FM muting for noise-free tuning, audio
muting switch for instant volume reductions, speaker selec-
tor and three pairs of speaker terminals permits speakers to
be used separately or A+B A+C. Jacks include MIC IN, two
phono inputs, two tape decks. headphones.

PRACTICAL AND AT THE SAME TIME ELE-
GANT DESIGN

With an exceptionally long dial for easy tuning. Easy,
perfect tuning with signal strength meter and center zero
meter. Slightly slanted front panel for easier dial reading.
Plus the incomparable PIONEER elegance of harmoniously
matched metal, black and natural wood.

FUSE REPLACEMENT

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