FEATURES

Plenty of Power at Low Distortion

Pioneers original newly developed monolithic power IC is
employed which composes a differential input SEPP OCL
circuit in the power amplifier section. Ample power and
low distortion stable stereo reproduction are assured.

Reliable Protection Circuit

Current limiter and thermal shutdown circuits are com-
bined in the protection circuit. Speakers and power IC are
protected from shorts due to faulty speaker connections or
other causes. A muting circuit is also included which blocks
surge noise when the power switch is operated on-off.

High Stability Direct Coupled Equalizer
Stringently selected PNP and NPN transistors are used in a
direct coupled circuit in the phono equalizer. Frequency
deviation governing record playback is held to within
10.5dB. This design also achieves improved stability at low
frequencies and advanced SN ratio.

Compatible with All Program Sources

In addition to special jacks for turntable and tape deck,
auxiliary (AUX) input jacks are provided for connecting
a cartridge tape player or other component. Virtually all
program sources can be connected.

2 Sets of Speaker Systems Can Be Used

The speaker switch can be used to select between two sets
of stereo speaker systems. A-B comparison listening or
simultaneous listening with speakers installed in another
room become possible. A single SA-SSOOII functions as two
stereo amplifiers in this manner.

Designed for Convenient Operation

Center point click stops are provided for tone and balance
controls, while the main volume control uses a 41 click stop
system. Ease of operation is given full consideration in the
design.

Clean and Simple Styling

Front panel layout is designed for both eye pleasing
simplicity and operational convenience. Since a matching
stereo tuner is also available,a high quality easily operated
stereo system can be set up.
