IMPORTANT: Do not apply power to this unit without
first making sure that speakers are connected properly and
all the other necessary connections are made.

This unit is equipped with terminals for connecting two
sets of speakers. Connect your main pair of speakers to
the terminals marked SPKR-I. Ensure that your right
speaker is connected to the terminal marked @ and that
the ground (-I terminal on the right speaker is connected
to the terminal marked 9 on the extreme left of the
terminal block. Similarly, connect your left speaker
between the adjacent SPKR-l terminals marked @and 9.
If you wish to connect a second pair of speakers, connect
them to SPKR-Z terminals in the manner described above.
Caution: Ensure that the speaker leads are fastened
securely to the proper terminals, and that there are no
stray strands which may cause shorting between terminals.
If 2 sets of speakers are played simultaneously, the
impedance of each unit should not be less than 8 ohms.
Phasing:

When all connections have been made, and the unit is
operating, a check on correct speaker phasing should be
made. This is described in a later section.

The shielded cables from your stereo record player should
be terminated with RCA type phcno plugs, To avoid loss
in the high frequencies, the cables should not exceed 10
feet (3 m) in length.

Connect both leads from your record player to the LEFT
and RIGHT PHONO input receptacles on the rear chassis.
If your record player has a ground cable emerging besides
two input cables, connect this ground cable to the ground
terminal post marked GND on the rear chassis.

This amplifier has two sets of PHONO input receptacles to
accommodate two record players. The PHONO I is
suitable for record player with regular magnetic cartridge,
The PHONO 2 is also for record player with magnetic
cartridge, but it has the variable input sensitivity and
impedance switches to match properly to characteristics
of your particular cartridge, See the OPERATION section
for using the switches.

If you wish to use ceramic cartridge, connect your record
player to either of AUX input receptacles.

Connect the outputs of your stereo tuner to the LEFT
and RIGHT TUNER input receptacles on the rear chassis
with shielded cables. if you have another tuner, connect it
to AUX 1 or AUX 2 receptacles.

Your amplifier has two pairs of AUX input receptacles for
use with high level program sources: tape recorder, tuner,

cassette recorder, 8-track cartridge player, TV sound or a
ceramic microphone. It should be noted that AUX is used
only for the playback purpose, and for recording see
TAPE RECORDER CONNECTION below.

When connecting a stereo tape recorder, connect both
output cables to the AUX LEFT and RIGHT input jacks
on the rear chassis. For cassette or 8-track cartridge,
similar procedure is followed. When connecting a mono»
phonic equipment, connect the single output lead to
either of the AUX LEFT or RIGHT input jack.

Terminals are supplied for connecting two tape recorders
(which incorporate playback preamplifier). Connect the
right and left output cables of the tape recorders to the
TAPE MONITOR terminals marked IN, and connect its
right and left input cables to the TAPE MONITOR
terminals marked OUT. If you have tape recorders with
DIN-type plugs, connect it to the REC/PB DIN sockets.

There are pairs of terminals marked PRE AMP OUT and
MAIN AMP IN, connected with a pair of jumper pins on
the rear chassis. Normally with the pins in place, you
reciever is the combined equipment of integrated pre»
amplifier and main-amplifier sections. However, by re-
moving the jumper pins, your unit in essence becomes two
independent components consisting of one pre- amplifier
and one main-amplifier.

These receptacles are intended for use with any necessary
equipment designed to be installed between the pre-
amplifier and the main-amplifier or for separate use of
either section alone. Such equipment as electronic audio
equalizer or reverberation unit can be used; or another
ore-amplifier or main-amplifier may be hooked up. Simply
disconnect the jumper pins and follow the instructions
supplied with the accessory equipment. When no auxilary
equipment is being used, the jumper pins MUST be
installed in place in order to use your amplifier.

Your amplifier is equipped with two switched AC Outlet
to provide power and switching control to whatever
component you may wish to connect to the unit.
However, the total load of equipment connected to the
AC Outlets must not exceed 200 watts, In addition, one
unswitched AC Outlet is supplied but without switching
control by the POWER switch.

The ampli er is a variable voltage equipment that can run
on IOOV, 117V, 220V or 240V power supply. Your unit
comes already preset at the proper voltage for use in your
area; however, if you move to an area where the power
supply voltage is different, the voltage setting can be
