Start with the Part 1 portion of your 901 system.
Place it on the left side of your room.
Connect
this left speaker to the left channel speaker output terminals of your amplifier or receiver.
(If there is a
choice of impedances on the amplifier output, use the terminal marked ""8Q2" or "8 OHMS") *
Connect the "COM" terminal on the left speaker to the "COM" terminal on the left channel output of your
receiver or amplifier output.
Connect the "8 OHMS" terminal on the left speaker to the "8 OHMS" ter-
minal on the left channel amplifier output.
Connect the right speaker (Part 2) in the same manner to the
right channel amplifier outputs (See Fig. 2).
Because of the differing terminology
which various manufacturers use on their receivers and amplifiers, we
have provided the chart below to assist you in identifying the proper connection points.

If stranded wire is used, be sure that the loose strands do not touch or short-out the speaker or amplifier
terminals.
Also make certain that all amplifier and speaker terminals are tightened securely.
*
If two pairs of 901s are being connected
in parallel, the terminal marked "492" or "4 ohms"
on
the
receiver or amplifier should be used.

FUSING YOUR 901 SPEAKERS
Any loudspeaker is subject to damage if the amplifier powering it should fail. The use of a fast-acting fuse
in series with each speaker will minimize the possibility of serious damage to your speakers.
BOSE Corpo-
ration
recommends
the
use of a 3-ampere
fuse, such
as
a BUSS
AGC
3 or a LITTELFUSE
3 AG
(3 amp).
The fuse should
be connected
in series with
either of the two wires in the cable to each
speaker.
A fuse holder, like a BUSS 3833-1 or a LITTELFUSE 356001 , may be used for convenience. (For
two pairs of BOSE 901s, use two 6-ampere fuses.)
