Subwoofer in standby mode

Green: Subwoofer on

With the Auto Standby function, the SKW-540
automatically turns on when an input signal is
detected in Standby mode. When there’s no input
signal for a while, the SKW-540 automatically
enters Standby mode.

OUTPUT LEVEL control

This control is used to adjust the volume of the sub-
woofer.

LINE INPUT

This RCA input should be connected to the sub-
woofer preout on your AV receiver, amp, or other
receiver with supplied RCA cable.

Note:

The Auto Standby function turns the subwoofer on
when the input signal exceeds a certain level. If the
Auto Standby function does not work reliably, try
slightly increasing or decreasing the subwoofer out-
put level on your receiver or amp.

Connecting the Speakers

Read the following before connecting your speakers:

• Turn off your amp before making any connections.

• Disconnect the power cord from the wall outlet before

making any connections.

• Pay close attention to speaker wiring polarity. Connect

positive (+) terminals to only positive (+) terminals,
and negative (–) terminals to only negative (–) termi-
nals. If the speakers are wired incorrectly, the sound
will be out of phase and will sound unnatural.

• Be careful not to short the posi-

tive and negative wires. Doing so
may damage your amp.

Use the cables to connect each speaker’s input
terminals to the corresponding speaker output
terminals on your receiver.

To make a connection, while pressing
the terminal lever, insert the wire into
the hole, and then release the lever.
Make sure that the terminals are grip-
ping the bare wires, not the insulation.

Using the supplied RCA cable, connect the sub-
woofer’s LINE INPUT to your receiver’s SUB-
WOOFER PREOUT.
