LINE VOLTAGE SELECTION AND FUSE

o HIGH-PERFORMANCE FM TUNER

An FET (field-effect transistor) is used in the radio-frequency amplifier to attain a high
sensitivity and selectivity. Further, four le (integrated circuits) are used for the
intermediatefrequency amplifier to eliminate interference and noise.

BUILT-IN EXCELLENT FM MPX CIRCUIT

This switching circuit having excellent separation and frequency response is built in for
reproduction of reality music.

BUILT-IN HIGHLY-SENSITIVE FERRITE ANTENNA FOR AM RE-

CEPTION
The ferrite antenna provides high-sensitivity reception of AM programs.

HIGH-PERFORMANCE DESIGN FOR VERSATILITY

In addition to the high power output attained by strictly selected transistors, the
versatile stereo receiver permits connection of three loudspeaker systems and two
turntables. It is also provided with terminals for tape recording output. center channel
output, preamplifier output and power amplifier input.

MICROPHONE IS USABLE

A microphone can be used by mixing during record play or other performance since an
independent microphone amplifier and level control are incorporated.

A VARIETY OF ACCESSORIES

Accessories include the program lamps that indicate the program being played, the
tuning meters vertically arranged for facilitating selection of an FM broadcast program,
the loudspeaker selector switch, tape monitor switch, etc., all for enjoyable use of
Model SX-ISOOTD.

ELEGANTLY DESIGNED FRONT PANEL

Newly designed knobs are uniquely arranged on the silver tone panel.

SWITCHING LINE VOLTAGE SETTING AND FUSE

In order to remove the fuse, turn the fuse cap located

on the line voltage selector switch in the direction
indicated by an arrow. Then remove the fuse plug
from the unit. Put the fuse plug back so that the
proper line voltage marking can be seen through the
cut in the edge of the plug.

Whenever the set position of the selector switch is
changed, check the rating of the fuse. A LES-ampere
fuse is to be used for either 220V or 240V operation
and 3-ampere fuse for any of 110V, 117V, or 130V
