FEATURES
7 Direct Energy MOS Power Amp(on the A-307R)
Pioneer introduces amp circuitry featuring Direct Energy
MOS FET devices for high performance. Together with
Pioneer's original Wide Range Linear Circuit technology,
this helps achieve reducing power consumption, while
maintaining the power of current models.
In terms of performance, it contributes to flat damping
factor characteristics across the audio spectrum, and im-
proved power linearity.
7 Advanced Direct Energy MOS Power Amp(on the
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.
INSTALLATION
LOCATION
Install the unit in a well ventilated location where it
will not be exposed to high temperature 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 compo-
nents. Installation of the unit in a damp or dusty environment
may also result in a malfunction or an accident. (Avoid instal-
lation 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.

Wide-Range Linear Circuit
This new current feedback circuit assures improved oper-
ating stability for flat output impedance and stable driving
of speakers across the full range of frequencies.

Silent microprocessor system
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 tem-
perature to rise, which may lead to breakdown or fire
hazard.
