FEATURES
Plenty of Power at Low Distortion
Pioneer's 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 ina
direct coupled circuit in the phono equalizer. Frequency
deviation

is held to within
+0.5dB. 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
