FEATURES
¶ Advanced Direct Energy MOS Power Amp
Pioneer incorporates highest quality amp circuitry featuring
Advanced Direct Energy MOS FET devices which can achieve
higher performance. Together with Pioneer's original Wide
Range Linear Circuit technology they reduce power
consumption while maintaining the power output of current
models.
In terms of performance, this technology contributes to flat
damping factor characteristics across the audio spectrum. It
also allows a wide range and especially ultra high frequencies
to be reproduced more accurately and improves power
linearity.
¶ Stabilizer
Transformer stabilizer, stabilizer frame (attached to chassis)
and volume stabilizer (attached to volume knob) deliver
powerful sound.
INSTALLATION
LOCATION
Install the unit in a well-ventilated location where
it will not be exposed to high temperatures or
humidity.
Do not install the unit in a location which is exposed to direct rays
of the sun, or near hot appliances or radiators. Excessive heat
can adversely affect the cabinet and internal components. Instal-
lation of the unit in a damp or dusty environment may also result
in a malfunction or an accident. (Avoid installation near cookers
etc., where the unit may be exposed to oily smoke, steam or heat.)
Do not install the unit on a tottered stand, nor on an unstable or
inclined surface.
VENTILATION
• When installing this unit, make sure to leave space around the
unit for ventilation to improve heat radiation (at least 60 cm at
top, 10 cm at rear, and 30 cm at each side). If not enough space
is provided between the unit and walls or other equipment,
heat will build up inside, interfering with performance or
causing malfunctions.
• Do not place on a thick carpet, bed, sofa or fabric having a thick
pile. Do not cover with fabric or other covering.
Anything that blocks ventilation will cause internal temperature
to rise, which may lead to breakdown or fire hazard.

¶ Designed for Low Power Consumption
This model incorporates several features for energy efficiency
to reduce power consumption.
1 Direct Energy Circuit
2 Local Off circuit: Tone Local Off, Phono Local OFF, Silent
Microcomputer
3 S-MOS: Instead of the digital transistors usually used in
logic circuits, this unit employs S-MOS devices in some
areas. These do not require base current, so they help re-
duce power consumption.
¶ Energy-Saving Design
This unit is designed to use minimal electricity when power is
switched OFF (during Standby).
Regarding the value of the power consumption in standby
mode, refer to "SPECIFICATIONS" on page 12 (back cover).
CONDENSATION
When the unit is brought into a warm room from previously cold
conditions or when the room temperature is suddenly increased,
condensation may form inside and the unit may not be able to
attain its full performance. In cases like this, allow the unit to stand
for about an hour or raise the room temperature gradually.
POWER-CORD CAUTION
Handle the power cord by the plug. Do not pull out the plug by
tugging the cord and never touch the power cord when your hands
are wet as this could cause a short circuit or electric shock. Do not
place the unit, a piece of furniture, etc., on the power cord, or
pinch the cord. Never make a knot in the cord or tie it with other
cords. The power cords should be routed such that they are not
likely to be stepped on. A damaged power cord can cause fire or
give you an electrical shock. Check the power cord once in a while.
When you find it damaged, ask your nearest PIONEER authorized
service center or your dealer for a replacement.
NOTES:
÷ If you use an other power cord than provided, we cannot
assume the liabilities in what may occur as a result of it.
÷ (The provided power cord has a current capacity of 2.5 A.)
