Power Amplifier with Ultra-wide-frequency-bartd
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 very 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'stage Darlington,
parallel push-pull output circuit configuration. All this adds
up to a DC amp configuration which uses SL RETs [Super
Linear Ring Emitter Transistors), which have an excellent
switching response in the high frequency range, for the
power transistors.
Continuous Power Output is 80watts' per chan-
nel, min.. at 8 ohms or 4 ohms from 10 Hertz to
20,000Hortz 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 tem-
perature down, and they ensure that a high-quality power is
provided.
Flat Amplifier with High S/N Ratio and Low
Distortion
This model adopts an ICL DC amplifier which is com-
posed of a twostage differential amplifier for the first stage
using ultra-low-noise 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 l lOdB (AUX).
Load Impedance Selector Switches
This 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
(l00/l0k/25k/50k/100k ohms), and the load capacitance
selector similarly has five settinp [l00f200/300I400ISOO
pF) so that the two selectors can be used independently,
They allow you to make settings which are in line with the
optimum values of the phono cartridge you are using and
also to create the sound quality of your choice.
Equalizer Amplifier for Faithful Reproduction of
Sound from Records
The equalizer amplifier is composed of a complementary
differential input which uses ultra-low-noise transistors for
the first stage, and a 3-stage direct~coupled all-stage push-
pull configuration. This results in yielding a low noise and
low distortion, a signaleto-noise ratio of 90dB (PHONO
MM) and an RlAA equalization of only 20.2dB across a
frequency spectrum of 20Hz to 20kHz. The maximum
rated input is 'ZSOmV (at lkHz, 0.002% total harmonic
distortion), proving that there is more than enough head-
room for the reproduction of sound from records.
Power Output Indication on Fluorescent Display
Tubes
The conventional needle-type of power output meters
have been replaced with the more up-todate fluorescent
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 80W range
without any assisting selection on the attractive fluorescent
display tubes.
