CASSETTE RECEIVER

Although it is neither complicated to install nor difficult to operate
your amplifier, a few minutes of your time is required to read this
manual for a properly wired installation and becoming familiar with its
many features and how th use them.
Please take a great care in unpacking your set and do not discard
the carton and other packing materials. They may be needed when
moving your set and are required if it ever becomes necessary to
return your set for sevices. Never place the unit near radiator, in front
of heating vents, to direct sun light, in excessive humid or dusty
location to avoid early damage and for your years of quality use.
Connect your complementary components as illustrated in the
following pages.

VERSATILE INPUT ADJUSTMENT

These models can be adjusted the input sensitivity from channel
1~5. Each of CH1~5 is composed of the balanced input and can
be changed the input and connector to phone jack or XLR jack
according to buyer's order.

FM RECEIVING ANTENNA

The electric wave of FM broadcasting is weakening in hills and valleys, around buildings and in iron-reinforced buildings
because of its own nature.

INSTALLATION OF AN ANTENNA EXCLUSIVELY FOR FM

Connect the feeder of the antenna to the terminal of 300 ohms(Fig. 1-1) Listening to the broadcasting, fix it after deciding
the location and the direction so that the recipt condition may be optimum.

INSTALLATION OF AN ANTENNA USING THE COAXIAL CABLE

You may feel the noise at the crowded dawntown, city streets and factory sites as well as around power cables, even in
the case of using an antenna exclusively for FM. In these regions, install it through connection with a coaxial cable of
75ohms.

INDOOR ANTENNA

In the regions where FM broadcasting is heard comparatively well due to the near distance to the station or wooden
structure, you can receive broadcasting of good quality by using T-type antenna. Fix the antenna at the best place for
receipt after connecting it with a terminal of 300 ohms.(Fig. 1-1)
