(-IMPORTANT

To prevent electric shock, do not remove cover, No user
serviceable parts inside, refer sen/icing to qualified serv-
ice personnel.

Always disconnect all the equipment from the mains
supply when disconnecting the signal leads. The power
card should be connected last, make sure that the power
switch is off. First, insert the female appliance connector
of the mains cord into the AC INLET, then plug the
cord'to the wall socket, Be sure that the appliance con~
nector is fully inserted into theAC INLET.

Unplug the set from the wall socket when it is not to be
used for an ex tended period of time.

WARNING
THIS APPARATUS MUST BE EARTHED.

FOR YOUR SAFETY

1. Insert this plug only into effectively earthed three-pin
plug-socket outlet.

3. Extension cords, if used, must be threecore correctly
wired.

2. If any doubt exists regarding the earthing, conmlt 0

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 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 smge 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 100watts*per chan~
nel, min, at 8 ohms or 4 ohms from 10 Hertz to
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»
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 two-stage 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 signa|~to noise ratio, and in main-
taining an S/N ratio of l lOdB (AUX),

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 3rstage direct-coupled all-stage push-
pull configuration This results in yielding a low noise and
low distortion, 3 signal-to-noise ratio of 90dB (PHONO)
and an RIAA equalization of only :0.2dB across a fre-
quency spectrum of 20Hz to 20kHz. The maximum rated
input is ZSOmV/MM (at lkHz, 0.002% total harmonic
distortion) and lOmV/MC, proving that there is more than
enough headroom for the reproduction of sound from
records.

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
(lOO/lOk/ZSk/SOk/lOOk ohms) and the load capacitance
selector similarly has five settings (100/200/300/400/
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 phono 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
derive the maximum in enjoyment from your MC car-
tridge is set the function selector to the 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 unto-date 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 100W range
without any assisting selection on the attractive fluorescent
display tubes
