FEATURES

7 Advanced Direct Energy MOS Power Amp
Pioneer incorporates highest quality amp circuitry featur-
ing Advanced Direct Energy MOS FET devices which can
achieve higher performance. Together with Pioneer's origi-
nal 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 fre-
quencies to be reproduced more accurately and improves
power linearity.
7
Stabilizer
Transformer stabilizer and stabilizer frame (attached to
chassis) deliver powerful sound.

INSTALLATION

LOCATION
Install the unit in a well-ventilated location where it
will not be exposed to high temperatures or humid-
ity.
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 compo-
nents. Installation 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).
WARNING:
Slot and openings in the cabinet are provided for
ventilation and to ensure reliable operation of the product and
to protect it from overheating, to prevent fire hazard, the
openings should never be blocked and covered with items,
such as newspapers, table-cloths, curtains, etc. Also do not
put the apparatus on the thick carpet, bed, sofa, or fabric
having a thick pile.
