Stereo Power
Amplifier. Prestige main amplifier with revolutionary V-FETs.
Power output
of 100 W + 100 W RMS from 20 Hz to 20 kHz, both channels driven, at 8 ohms and
under 0,1% THD.
Newly
developed P-channel and N-channel V-FETs in a true complementary triple
push-pull circuit which is coupled directly to the speaker terminals for
faithful signals.
Dual FETs in
triple differential circuit of Class-A amplification stage - for stable
performance regardless of temperature fluctuation as well as for high input
impedance.
Optical
peak program meter - extremely quick response to show accurately the amount of
power being fed to the speakers. Two-position sensitivity switch of X 1 (from 0
to 200 W) and X ¹/₁₀ (from 0 to 20 W).
Chimney type
heat-sink provides effective cooling for stable performance.
Speaker
Level Control
An
independent level control is provided with B-speaker circuit (convenient to
test or balance two different systems or to compensate for a difference in
speaker efficiency)
Subsonic
Filter
Prevents
sound from adversely affecting by inaudible low frequency components, such as
those generated by rumble or acoustic fedback in a turntable system
(Normal/test switch on the rear panel).
Sony power
V-FET (Vertical Field Effect Transistor)
V-FET has
ideal characteristics for an audio amplifier:
Quick
transient response to pulsive signals, which assures minimum distortion and
excellent phase response.
High input
impedance and low output impedance, which allows excellent circuit design with
greater flexibility and ease.
Smooth
pinch-off characteristics which assures miniumu distortion.
Voltage
controlled input characteristics which cause virtually no partial current
concentration, assuring temperature stability.
