Thank you for selecting the Sansui 4000 AM/FM Multiplex
Stereo Tuner Amplifier. You have made an excellent choice, one
that promises you years of rich stereo enjoyment.

As the worlds foremost audio-only specialist, Sansui has spared
no effort in making the 4000 the most powerful, most versatile
and most sophisticated receiver available at its price. With an
unprecedented 160 watts in power, the latest FET and IC com-
ponents, functional black face front panel design and an ability
to handle three speaker systems simultaneously or individually
the 4000 considerably advances the art of stereophonic repro-
duction.

Before leaving our factory, your new 4000 was tested, inspected
and certified to be in perfect operating condition. It is now up
to you to keep it that way.

This manual has been prepared to guide you in installing and
operating the receiver correctly. It contains some very helpful
information on making antenna connections, using controls pro-
perly and operating components most effectively. Please read it
carefully before operating the receiver and retain it for future
reference.

SPEAKER CONNECTIONS

Connecting a Main Speaker System
Connect the speaker on your left (as viewed from
the listening area) to the red terminal marked LEFT
SYSTEM-A on the rear panel of the amplifier. The
right speaker connectionsl'are made at the red ter-
minal marked RIGHT SYSTEM-A. The lead from
the commom speaker terminals marked - or C
should be connected to corresponding black terminal
marked - on the amplifier.

To connect to the terminals of the amplifier:

1. Depress the colored button, opening a hole in
the terminal.

2. Push the stripped end of lead wire in the hole
and release the button.

After connecting the speaker system, set the front
SPEAKERS switch to the A position'

Connecting Additional Speaker

Systems

Following the same procdure indicated above, one
or two more speaker systems can be connected to
the 4000 by utilizing the speaker terminals SYS-
TEM-B and SYSTEM-C respectively.

Each of the three systems can be operated independ-
ently with the SPEAKERS switch on the front
panel. In addition, the sperker systems A and B can
be operated simultaneouslybvhen the SPEAKERS
is set to the A+B position, and the speaker systems
A and C can be operated simultaneously when the
switch is set to the A+C position.

If Speaker Polarities Are Not

Properly Matched . . .

If the polarities (+ and -) of the speakers and the
amplifier are not matched correctly, sound cancella-
tion at some frequencies or in some listening posi-
tion occurs. Particularly when listening to monau-
ral reproduction, this condition is noticeable by an
absence of sound at a point midway between right
and left speakers. If this situation occurs, check
the amplifier and speaker connections once more
and reverse the connections between the amplifier

and either the right or left speaker.

Speaker Impedance

1. For use with a 4-ohm speaker system, connect
it to any one of the AB and C speaker system cir-
cuits.

CAUTION: Never attempt to use two or three 4-
ohm speaker systems at the same time.

2. For use with the three speaker systems, the im-
pedance must be more than 4 ohms each.

3. For use with the two speaker systems (A+B or
A+C), the combined impedance of the A+B or
A+C systems must be more than 4 ohms.
