FEATURES

Power Amplifier with Ultra-wide-frequency-band
Output and Low Distortion

This amplifier has the impressive feature which is the
NSA (Non-Switching-Amplifier), created specially by
Pioneer. This is a type of amplifier that adopts the merits of
both the class A and class B amplifiers, and it excels in
keeping down the heat loss and allows the transistors to
operate all the time in the active region. For this reason, a
high output power with a \éry low distortion factor is
yielded all the way up to the high frequencies.

Also it is designed to pack a punch at every stage -» this
is evident in the first stage differential input, current mirror
load; the predriver stage emitter follower drive, constant»
current load; and the output stage 2-stagc Darlington,
parallel push-pull output circuit configuration. All this adds
up to a DC amp configuration which uscs SL RETs [Super
Linear Ring trnitter Transistors), which have an excellent
switching response in the high frequency range, for the
power transistors.

Continuous Power Output is 100wattsper chan-
nel. min., at 8 ohms or 4 ohms from 10 Hertz lo
20,000Hertz with no more than 0.005% total

harmonic distortion.

T-shaped "skyve" heat sink is used because it is
lightweight and it dissipates the heat very effectively.
Even when the amplifier is operating continuously under
full power conditions, these heat sinks keep the rise in tern-
peraturc down, and they ensure that a highquality power is
provided.

Flat Amplifier with High S/N Ratio and Low
Distortion

This model adopts an IQ. DC amplifier which is com-
posed of a twostage differential amplifier for the first stage
using ultra-low»noisc dual FETs and an emitter follower for
the final stage. This construction is successful in achieving a
low distortion and a high signal-to noise ratio, and in main-
taining an SIN ratio of llOdB (AUXL

Equalizer Amplifier for Faithful Reproduction of
Sound from Records

lite equalizer amplifier is Comprised of a complementary
dillcrcnlldl input which uses ultrnvlnw-noise transistors for
the first stage. and a 3-stage direct-coupled t|||'\lrg[ push»
pull configuration. this results in yielding a low noise and
low distortion, 3 signal-tortoise ratio of 90dB {PHONO}
and an RIAA equalization of only £0.2dB across a fro~
quency spectrum of 20Hz to 20kHz. The maximum rated
input is 250mV;'MM (at lkHz, 0.002% total harmonic
distortion) and lOmVJMC, proving that there is more than
enough headroom for the reproduction of sound from
records.

Load Impedance Selector Switches

lhis amplifier comes with cartridge load selectors which
make it possible to display the performance of moving
magnet (MM) cartridges to the full for sophistication in
operation. The load resistance selector has five settings
[IOO/lOk.25kaOk/100kohms] and the load capacitance
selector similarly has five settings (1004'200/300/400f
SOOpF), so that the two selectors can be used inde-
pendently. They allow you to make settings which are in
line with the optimum values of the phone cartridge you
are using and also to create the sound quality of your
choice.

Another feature is the MC position which means you
can connect a moving coil (MC) cartridge with a subtle
and delicate sound quality directly. All you have to do to
dcrii-c the maximum in enjoyment from your MC car»
tridgc is set the function selector to thc PHONO 2 MC
position.

Power Output Indication on Fluorescent
Display Tubes

The conventional needle-type of power output meters
have been replaced with the more up-todare lluoresccnt
display tubes featuring digital technology. They employ
logarithmic compression circuits and a peak hold circuit to
indicate the power output over a 0.3mW to 100W range
without any assisting selection on the attractive fluorescent
display tubes.
