SX-5560 FEATURES

Stable Operation in FM Tuner Section

The FM front end includes dual gate MOS FET and a high
precision 4-ganged variable capacitor. The IF amplifier
circuit employs a high integration density [(3 developed by
Pioneer and three dual-element phase-linear ceramic filters
to achieve a maximum of stability. Stable multiplex circuit
operation is assured by the PLL IC design to which a newly
developed type of negative feedback has been applied. This
design provides low distortion with a high degree of
reliability. In all important respects, including station drift,
image rejection ratio, S/N ratio, capture ratio, and sensi-
tivity, the crystal clear FM reception this tuner provides
will satisfy the most discriminating taste.

Wide Power Bandwidth, Low Distortion Power
Amplifier

The use of a first stage differential amplifier, and a pure
complementary power amplifier allows high power output
over a wide bandwidth to be obtained with a very low disr
tortion rate. SX-SSGO delivers

Continuous power output of 50 waits*per chan-
nel minimum RMS at 8 ohms from 20 Hertz to
20,000 Hertz with no more than 0.1% total
harmonic distortion.

The two 15,000 [.LF electrolytic capacitors in the power

supply permit high sound quality even at lowest fre
quencies.

Pre-Amplifier Design Assures High Fidelity
Reproduction

By using a differential amplifier at the first stage input
impedance variations due to frequency are minimized,
a PHONO input capability of 200mV with a distortion
of 0.1% at 1 kHz is obtained, This, in combination with
the careful selection of semiconductors used, holds RIAA
deviation to within 10.2dB (3OHZ~lSkHz). You are
assured of faithful reproduction of your records over
a wide dynamic range with no discernible distortion.

High Reliability Protection Circuit

The protection circuit and power relay are designed to
instantaneously open the output circuit in the event of
a short in the speaker leads or current surges which may
occur without warning. This feature prevent, damage to
speakers or transistors, and also prevents click noises
during operation of the power switch.

Duplicate Switch for Recording or Editing of
Tapes

Two sets of TAPE terminals and the DUPLlCATE switch
permit one to selectively record from one tape to another
when two tape decks are connected to the amplifier at the
same time. it is thus possible to record onto a cassette from
an open reel tape deck, or vice versa.

New, Attractive Visual Design

The large tuning scale provides more readable and hence
more precise location of the desired frequency. The front
panel has been designed for improved operating con-
venience.
