Loudspeaker Input Terminals:
When connecting the Loudspeaker Hookup Cables to
the XRT2.1K Loudspeaker Input Terminals please fol-
low the steps below:
1. Rotate the end of the Input Ter-
minal Post counterclockwise
until an opening appears. Refer
to figures A and B.
2. Insert the Loudspeaker hookup
cable into the Input Terminal
Post opening or the cable spade
lug around the center post of the
Input Terminal. Refer to figure
C.
3. Rotate the end of the Input Ter-
minal Post clockwise until it is
finger tight. Refer to figure D.
4. Place the supplied McIntosh
Wrench over the end of the
Input Terminal and rotate it one
quarter of a turn (90° ) to secure
the Loudspeaker Cable Connec-
tion.
Do not over tighten.
Refer to figure E.
Preparing the Loudspeaker Hookup Cables:
When connecting a XRT2.1K Loudspeaker to an
amplifier, it is very important to use cables of ad-
equate size, so there is little to no power loss in the
cables. The size is specified in Gauge Numbers or
AWG (American Wire Gauge). The smaller the Gauge
number, the larger the wire size:

Bare wire cable ends:
Carefully remove sufficient insulation from the cable
ends, refer to figures
23, 24 & 25. If the
cable is stranded,
carefully twist the
strands together as tightly as possible.
Notes: 1. If desired, the twisted ends can be tinned
with solder to keep the strands together.
2. The prepared bare wire cable ends may be
inserted into spade lug connectors.
3. Banana plugs are for use in the United
States and Canada only.
Banana Plugs for cable ends:
1. Attach the previously prepared bare
wire cable ends into the banana plugs
and secure the connections. Refer to
figure F.
2. Rotate the top of the Output Terminal
Post clockwise until it is finger tight.
Refer to figure G. Then using the
McIntosh Wrench, rotate the top of
the Output Terminal one quarter of
a turn (90° ).
Do not over tighten.
Refer to figure E.
3. Referring to figure H
and the illustration on
the next page, connect
the Loudspeaker hookup
cables with banana plugs
into the hole at the end of the Input Terminal.
Note: It is important to maintain the correct polarity
at both ends of the Loudspeaker cables.
Spade Lug or Wire Connections:
1. Insert the spade lug connector or prepared section
of the cable end into the Input Terminal side access

How to Connect with One Power Amplifier
Caution: Do not connect the AC Power Cord to the Power
Amplifier Rear Panel until after the Loudspeak-
er Connections are made. Failure to observe
this could result in Electric Shock.
The connection instructions below, together with the
XRT2.1K Connection Diagram located on the separate
folded sheet “ Mc2A ”, is an example of a typical audio
system. Your system may vary from this, however the
actual components would be connected in a similar
manner.
Power Control Connection:
1. For Remote Power Control, connect a power control
cable from the Audio Preamplifier or A/V Control
Center Power Control Output 1 (TRIG 1) to the
Amplifier POWER CONTROL IN.
2. Connect a power control cable from the Power
Amplifier POWER CONTROL OUT
to the XRT2.1K POWER CONTROL
IN. Refer to figure 22.
3. Connect a power control cable from the
XRT2.1K POWER CONTROL OUT
to the next XRT2.1K POWER CON-
TROL IN.
Audio XLR Cable Connection:
1. Connect an XLR cable from the Balanced Output
1 Left Channel, (refer to note 2 below) of an Audio
Preamplifier or A/V Processor, to the Amplifier
BALANCED INPUT. Place the INPUT MODE
Switch in the BALanced Position.
Note: 1. An optional hookup is to use an unbalanced
cable and place the INPUT MODE Switch in
the UNBALanced Position.
2. When multiple Power Amplifiers are used,
match up the Preamplifier or A/V Processor
Channel Output designation to each Power
Amplifier with the Loudspeaker and the
Loudspeaker location in the room.
