Connecting the Subwoofer to Digital Home Theater Systems Using LFE
Multi-channel home theater electronics dedicate one channel (the “.1”) to reproduce the low-frequency effects (LFE)
(such as explosions and thunder) contained in digitally-encoded soundtracks.
Hooked up this way, the receiver’s amplifier is relieved of having to reproduce the difficult low bass signals that can drive the
receiver into audible distortion. In some cases it can also depend on several other settings within a receiver. We recommend
consulting your receiver manual for further assistance in this area.
Use an audio RCA cable (not included), as shown, to connect your digital receiver’s LFE/subwoofer output to the subwoofer.
Connect the other end to the Line Level/LFE input.
Connecting to Electronics Without a Subwoofer Output
If the preamp/receiver in your system does not have a subwoofer or LFE output you can connect the MSubwoofer
to a preamp/variable output. Use a stereo audio RCA cable (not included) to connect the preamp outputs to the “L” and “R”
Line Level inputs. Note: for preamps without multiple preamp outputs, splitters may be required.
