McIntosh Single Channel Amplifier Number One
How to Prepare Hookup Cables
The McIntosh XRT30 Loudspeaker System utilizes bind-
ing posts for speaker wire connections. Prepare the Loud-
speaker Hookup Cables that attach to the Power Amplifier
Output Terminals:
Bare wire cable ends:
Carefully remove sufficient insulation from the cable
ends, refer to figures 20, 21 & 22. If the cable is
stranded, care-
fully twist the
strands to-
gether as
tightly as pos-
sible.
Note: If desired, the twisted ends can be tinned with
solder to keep the strands together and/or attach a
spade lug.
Spade lug or prepared wire connection:
Insert the spade lug connector or prepared section of
the cable end into the terminal side access hole, and
tighten the terminal cap until the cable is firmly
clamped into the terminal so the wires cannot slip out.
Refer to figures 23, 24 & 25.
How to Connect using three Amplifiers
1. Connect a Loudspeaker cable from the Negative (-)
Binding Post of the Amplifier Number One to the
XRT30 Bass Section SYSTEM INPUT COMmon (-)
Binding Post.
Note: The SYSTEM INPUT AND WOOFER DIRECT
COMmon (-) Binding Posts on the XRT30 Bass
Section must have a jumper installed between them. If
the Audio or Home Theater System Electronics has the
capablilty of a Electronic Crossover set to 80Hz,
remove the jumper between the SYSTEM INPUT AND
WOOFER DIRECT COMmon (-) Binding Posts on the
XRT30 Bass Section and save it for possible future
use. Connect the Amplifier that is reproducing the
frequency range from 20Hz to 80Hz to the WOOFER
DIRECT Binding Posts, instead of the SYSTEM
INPUT Binding Posts.
