High-power Output of 40W+40W/8

(DIN)

7

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.

7

Low power consumption design.

7

Complementary capacitor pair.

7

Direct Energy MOS Power Amp

Pioneer introduces amp circuitry featuring HEX power
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.

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). 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.
