How to Connect
McIntosh Seven Channel Power Amplifier
McIntosh A/V Control Center
The McIntosh XLS112 Powered Subwoofer may be turned
On or Off by two different methods. The preferred method
is to utilize the Power Control Signal from a McIntosh A/V
Control Center or Audio Control Center. If the Power Con-
trol Signal is not available, the XLS112 has built-in signal-
sensing circuitry which will automatically turn-on the Pow-
ered Subwoofer.
1. Connect a power control cable from the McIntosh A/V
Control Center or Audio Control Center Power Control
Out Jack to the McIntosh XLS112 POWER CONTROL
IN Jack.
2. Connect a power control cable from the McIntosh
XLS112 POWER CONTROL OUT Jack to the McIn-
tosh Power Amplifier Control In Jack.
Notes: 1. If two or more McIntosh XLS112 Powered
Subwoofers are being used in the same system,
connect the POWER CONTROL OUT from the
first XLS112 to the next XLS112 POWER
CONTROL IN Jack and then onto the McIntosh
Power Amplifier.
2. The XLS112’s Power Control Input will
function with 5 to 20 Volts DC applied.
3. Connect a Balanced Audio Cable from the McIntosh
A/V Control Center or Audio Control Center
Subwoofer Out to the McIntosh XLS112 MONO
INPUT(S).
Notes: 1. If two or more McIntosh XLS112 Powered
Subwoofers are being used in the same system,
connect a second Audio Cable from the first
XLS112 MONO OUTPUT(S) to the next
XLS112 MONO INPUT(S).
2. The unbalanced L (Left) or R (Right)
INPUT(S) jack may be connected instead of the
Balanced Input jack.
3. If the input signal is insufficient for proper
system balance, connect an unbalanced cable
from the McIntosh A/V Control Center or
Surround Decoder Subwoofer Out to a “Y”
adapter and connect the “Y” adapter outputs
to both the L (Left) and R (Right) INPUT
Jacks. This will increase the input gain of the
XLS112 by 6dB.
4. Attach to the Front Panel the supplied Loudspeaker
Grille.
5. Connect the XLS112 power cord to an active AC out-
let.
