INTRODUCTION

This INTEGRATED STEREO AMPLIFIER was developed
and engineered by Sanyo to be a source of entertainment and
listening pleasure for many years to come.

Before you install and start operating your unit, please read
the instructions in this booklet carefully. This will prevent
errors in operation and will assure faultless performance of
your unit and maximum listening enjoyment.

PREPARATION

l.
2.

3.

Unpack the unit. (Save cartron and fillers for future use.)
Make all connections before inserting line cord into an AC
wall outlet.

This model is already set for a fixed voltage level. If it is
used in a different voltage area from that indicated on the
power cord label. the setting should be changed.

To alter the voltage, change the voltage selector (located
at the rear panel) to the right position which corresponds to
your local voltage.

HOW TO CONNECT INPUT/OUTPUT TERMINALS

INPUT connections

PHONO (Connecting turntable)

Connect the output cables of a turntable with magnetic

cartridge to the jacks marked INPUT PHONO.

The upper INPUT jack is for the L (left) channel and

the lower one for the R (right) channel. Be sure to make

the correct connections. The ground wire from the turn-
table should be connected to the terminals marked GND.

NOTE:

(I) In some rare instances involving particular types of
turntables and cartridges. the use of a ground wire
causes a noise problem. Should this be the case, do
not make this ground connection.

(2) There are various types ofcartridges for turntables.
They may differ in output voltage and impedance.

TUNER (Connecting tuner)

Connect the output cables of the system tuner to the

jacks marked INPUT TUNER, matching the R and L marks.

AUX

The AUX jacks are spare input terminals for use when

connecting an 8-Irack tape player or a second system tuner.

. GROUND (GND)

This terminal is provided for a connection to the system
turntable and system tuner.

. TAPE (Connecting tape deck)

Be sure to make correct connections. taking note of the
REC, PB. R and L marks.

REC jacks (tape recording terminals)

Connect these jacks to the LINE IN terminals on the
system tape deck for making tape recordings.

PBjacks (playback terminals)

Make a connection between PB and LINE OUT of the
system tape deck for playing tapes.

4. SPEAKERS (Connecting speaker systems)
Connect to the speaker terminals marked R the speaker
system which is to be placed to the right of the amplifier
as seen from the listening position and the left channel
speaker system to those marked L.
Be careful to observe Lhe correct polarity of the speaker
connection. The (+) and (-) poles of speakers must match
the (4-) and (-) terminals of the amplifier. (Use two-
colored speaker leads for correct connection.)
If the polarity is not indicated on the speaker system.
connect them anyhow. If the sound does not come from a
point between the two speakers, and if bass response
appears insufficient, the speaker connections are out of
phase. Change the (+) and (-) connections on one of the
speakers.
CAUTION:
Be careful not to cause a short circuit between the speaker
terminals. (See Protector fuse.)

. SWITCHED(AC outlet)
Being interlocked. this AC outlet is switched on and off
by the POWER switch on the front panel and is a conve-
nient power source for the system tuner.

. UNSWITCHED (AC outlet)
Not being interlocked. this AC outlet for system com-
ponent remains live irrespective of the ON/OFF settings
of the POWER switch. Use this as power source for the
turntable or tape deck.

Each of the SWITCHED AC outlets has a power rating of
100 W maximum total and the UNSWITCHED AC outlet
has a power rating of I00 W maximum total. They should
be used for supplying power to audio equipment only.
Never use them as AC outlets for other electrical appli-
ances.

. MIC MIX (Mic-mixing recording) switch
When recording simultaneously from either the external
radio or phonograph and the microphone, or from the
microphone and another sound source, set the MIC MIX
switch to ON, otherwise keep it to OFF position.
NOTE:
Refer to
TIVEL

. PROTECTOR (Protector fuse)
Protector fuses protect your speaker and the amplifier.
If a fuse blows. turn the power switch to OFF and make
sure the speaker terminals are not shorted at the amplifier
or speaker end.
Then replace fuse with the same type fuse.

. AC (Power cord)
After completing the connections of all system compo-
nents, make sure that the POWER switch on the front panel
of this amplifier is set to OFF.
Then, plug the power cord into an AC wall outlet.
NOTE:
Hold the power cord by the plug when disconnecting it
from the power source Do not pull on the cord.

. AC SELECTOR
Refer to PREPARATION.
