For traditional subwoofer use in audio/video systems in multi-channel home theater applications, connect the line level LFE output of your processor to the LFE input on the S4/8.
Our unique LFE Blend™ technology allows you to use the S4/8 in BOTH your music system and your home theater system at the same time by using the high-level speaker inputs to augment the bass response of your satellite speakers and connecting your processor’s LFE output to the LFE Input. You are able to blend the two signals together for better bass management of your listening room.
The S4/8’s LFE out can be used to daisy-chain multiple Genesis subwoofers together for better control of the bass modes in your listening room. This makes bass management easier, and makes for tight, fast, articulate bass.
Placement of the Subwoofer
One of the most common reasons to buy a subwoofer is to augment your existing loudspeakers when they do not provide enough bass for your liking. In general, the S4/8 is used to augment front main or center speakers in a multi-channel system, and would be placed near the center channel or in between two main front speakers.
In this case, you should also connect the LFE input of the S4/8 to the LFE/Subwoofer output of your processor (or daisy-chained from the nearest Genesis subwoofer with an LFE output). Since the S4/8 has speaker-level inputs for two channels, you can place a single sub between the two front speakers of your multi-channel system.
In a stereo system, you could place the S4/8 in between the left and right speaker and connect them to both. In general, it is never advisable to have your subwoofers placed symmetrically in a room. Hence, we recommend that it be placed nearer the right speaker.
Adjusting the Controls
Locate the spec sheet for your existing main L/R loudspeakers or center channel, and adjust the Low Pass frequency on the S4/8 so it matches the –3dB point of your speaker’s frequency response (If you can’t find that the -3dB frequency, set the S4/8 to 63Hz – the 12 o’clock position on the knob – and tune by ear from there). For speakers of general sensitivity (around 88dB to 93dB), the Bass Gain and LFE Gain can also be set at the 12 o’clock position.
