If you don't have a subwoofer output available, check to see if you have preamp outputs on your preamp, amp, or
processor to be able to use these inputs. If you have only one set of preamp outputs, use a Y-connector to feed both
the amplifier and the subwoofer. See Figure 2. Use a Y-connector to connect the signal to both the LEFT and RIGHT
inputs of the subwoofer. These inputs are summed to mono in the amplifier input stage of the subwoofer.
USING SPEAKER WIRE CONNECTIONS
Some M&K subwoofer owners hook up their subwoofer by connecting it to their receiver or amplifier using speaker
wires. To do so, you make the same kind of connections that you would use for your satellite (or main) speakers, except
that both the left and right channels go to the subwoofer. (If you are using two subwoofers, connect one channel only
to each subwoofer).
1. Run speaker wire between the Amplifier's Left channel output terminals and the subwoofer's Left
channel "FROM AMPLIFIER" terminals.
A. Connect the Amplifier's Left channel Positive (+) terminal and the subwoofer's Left RED (+)
"FROM AMPLIFIER" terminal.
B. Connect the Amplifier's Left channel Negative ( — ) terminal and the subwoofer's Left BLACK
( — ) "FROM AMPLIFIER" terminal.
2. Make matching connections for the Right channel. See Figure 3.
IMPORTANT NOTE FOR DOLBY PRO LOGIC SURROUND SYSTEMS: (NOT DOLBY DIGITAL 5.1)
When the subwoofer is connected to the Left and Right amplifier outputs, the Center channel WIDE/NORMAL switch
MUST be set to the NORMAL mode. If the switch is set to the WIDE mode, the bass content of the Center channel will
not be fed to the subwoofer, and a significant amount of bass in the program material will not be reproduced.
SATELLITE SPEAKER WIRING OPTIONS
If you use speaker wires to connect the subwoofer, you have two options for the Satellite speakers.
1. Connect both the satellite speakers and the subwoofer direct to your amp or receiver, with one
set of wires running to the satellites and another set to the subwoofer. See Figure 4, below.
