Connecting the Subwoofer
A subwoofer is connected to a HiFi or surround-sound system using RCA and/or loudspeaker cables. The variants described
below provide an overview of the dierent possible applications.
You should also refer to the operating instructions for the AV receiver and the other loudspeakers used in the setup.
Digital surround-sound systems
Standard connection LFE IN (Low Frequency Eect IN)
The rear panel on most surround-sound ampliers includes a special RCA output socket (“BASS” / “SUB OUT” / “LFE”) for
connecting an active subwoofer. This output is connected to the “LFE” input socket on the subwoofer using a mono RCA cable.
Since this RCA connection only sends bass signals to the subwoofer, the “CUTOFF FREQUENCY” parameter on the subwoofer
can be set to the maximum value.
If your surround-sound amplier does not have a “SUB OUT”, or if the soundstage achieved using the standard connection
method described here is not satisfactory due to the bass management function in the AV receiver, you can also use the
“Advanced connection variant” (see page 28) as an alternative.
