FEATURES

7Direct 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.

7Advanced Direct Energy MOS Power Amp(on the A-209R)

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 ultraÊ high fre- quencies to be reproduced more accurately and improves power linearity.

7Stabilizer (on the A-209R only)

Transformer stabilizer and stabilizer frame (attached to chassis) deliver powerful sound.

7Low power consumption design

7High-power Output:

A-307R

80 W + 80 W/4 Ω (DIN)

 

55 W + 55 W/8 Ω (DIN)

A-209R

60 W + 60 W/4 Ω (DIN)

 

45 W + 45 W/8 Ω (DIN)

7Wide-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.

7Silent microprocessor system

INSTALLATION

LOCATION

VENTILATION

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.

ÖWhen 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.

ÖDo 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.
