Connections
1b. If your receiver/processor does not have a dedicated subwoofer output but
does have preamp-level (volume-controlled) line outputs, use the included
LFE cable to connect one of those outputs to either of the subwoofer’s Line-
Level L/R In Connectors. Use an RCA cable (not supplied) to connect the
other receiver or preamp line output to the other subwoofer Line-Level L/R
In Connector.
If you’re connecting to a receiver or preamp/processor with left and right line outputs
that are connected to front left and front right amplifier inputs, connect the single ends of
Y-adapters (not supplied) to the receiver or processor’s left and right line outputs. Connect
one of the Y-adapter’s double ends to the subwoofer’s Line-Level L/R In Connectors, and
connect the other double end to your amplifier’s front left and front right inputs.
2. After you have made and verified all other connections, plug the subwoofer’s
Power Cord into an active, unswitched AC outlet. DO NOT plug this cord into
the accessory outlets found on some audio components.
