FEATURES

MONO-CONSTRUCTION

Independent power transformers are provided for left and right

channels, with an additional transformer for control and display

functions. This three-transformer design prevents deterioration

of sound due to interference between channels.

HYBRID MC TRANSFORMER

The

transformer

winding

ratio between

reduced

(1/2 of

Pioneer

models},

thus improving

low-frequency

and

high-frequency MC transformer response.

VIBRATION-RESISTANS DESIGN

In order to eliminate

sound

deterioration

from vibration, the

amplifiers supporting legs have been made from special resin

material, and pure aluminum has been used for the volume con-

trol knob.

ELECTRONIC CONTROL

Signal switching is performed by relays and electronic switches

in order to shorten the signal path, thus reducing noise and im-

proving separation and other characteristics.

PRECAUTIONS DURING USE

HIGH-SOUND-QUALITY MOTOR DRIVE

VOLUME CONTROL

Volume control is performed by motor drive, thus reducing distor-

tion.

HIGH-FIDELITY PARTS

All parts, from circuit boards to resistors, capacitors, semiconduc-

tors, and wiring, have been specially developed for high-fidelity

audio applications. In addition, a copper-plated chassis has also

been adopted for even greater sound quality.

FULL VIDEO FUNCTIONS

In addition to five (plus one adapter) audio inputs, five (plus one

adapter) video input terminals have also been provided. in addi-

tion, a REC selector and enhancer function have also been built in-

to the video system.

AV REMOTE CONTROL UNIT WITH LEARNING

FUNCTIONS

With

the attached

remote

control

unit you

can

operate

any

Pioneer audio or video component bearing the

mark. And

with additional learning functions the whole AV surround system

including TV and VCR of other makers can be controlled. (Some

makers' remote control systems, however,

are not suitable for

programming.)

ABOUT INSTALLATION

Avoid high temperature and humidity, and allow sufficient ventila-

tion,

Excessive heat can adversely affect internal parts. Avoid foca-

tions exposed to direct sunlight or the heat from a space heater or

other heating appliance. Also, malfunctions may aresult if the

unit is installed in locations with high-humidity or high concentra-

tions of dust. {Also avoid kitchen installations or other locations

exposed to oily smoke, steam, or heat.)

PRECAUTIONS FOR INSTALLATION

To ensure optimum sound quality, observe the following precau-

tions:

* This unit is heavy. Be sure to install it on a firm base which can

support its weight. Also, to prevent the flow of cooling air from

being blocked off, do not place the unit on soft material such as

@ carpet or cushion, or install it in a confined space. When in-

stalling the unit in a rack, provide adequate space around it to

allow heat to dissipate.

* To prevent the contro! amplifier from picking up noise due to

leakage

flux

from

the

power

amplifier

when

the

control

amplifier and power

amplifier are installed adjacent to each

other, install the control amplifier on the right of the power

amplifier. Also, if you install the control amplifier above or

below the power amplifier, place a partition between them to

separate them by at least 10 cm from each other.

install the unit on a level surface so that the feet of the unit are

ali touching the installation surface.
