Unpacking and Installation

Although it is neither complicated to install nor difficult to operate your

power amplifier, a few minutes of your time is required to read this manual

for properly wired installation and becoming familiar with its features and

how to use them. Please take great care in unpacking your set and do not

discard the carton and other packing materials. They may be needed when

moving your set or if it ever becomes necessary to return your set for

service. Never place the unit near a radiator, in front of heating vents, in

direct sunlight, or in excessively humid or dusty locations. Connect your

complementary components as illustrated on the following pages.

Installation of the Speakers

When connecting or changing speakers, always remove the power cord from

AC outlet, and use the appropriate terminals as below. For 25V and 70V

line, be sure that total impedance is not less than rated impedance.

4 ohm and 8 ohm must be properly impedance matched.

NOTE : These are examples of possible wiring situations. Many other

possibilities exists. Always maintain impedance matching for 4 and 8

ohm connection. Do not exceed the power rating of the amplifier by

connecting more speakers than the unit is rated for. If you are in doubt,

please consult a professional installer.

1. Select 110V AC or 220V AC operation with this switch. Then

plug AC cord into AC outlet.

2. FUSE HOLDER(AC)

This fuse holder contains the AC power fuse. Replace only with

same type fuse when it is blown. If it continuously blows, stop

replacing fuse and refer servicing to qualified personnel.

3. SPEAKER OUTPUT TERMINALS

Theseterminalsareforspeakerconnection. Youcanselect4ohmor

8ohm or line outputs or 25V (2.6ohms) and 70V (20.4ohms). Be sure

not to make the total impedance less than rated impedance on 25V

or 70V. 4 ohm and 8 ohm must be matched exactly.

NOTE : Please note that only 25V or 70V terminals should be

connected when using speaker/zone selector.

4. INPUT JACK

Right and left inputs are combined to serve as a " Y " connector

(stereo to mono).

5. COOLING FAN

This Unit incorporates a cooling fan to reduce the operating temperature

of the amplifier. affording better performance and longer operational life.
