LFE Gain
The S2/12t has a control for LFE GAIN that is separate from BASS
GAIN. This allows you to have the S2/12t augment your surround
speakers as well as deliver LFE around the room at the same time
without conflicts. The usual way to control the level of the LFE output is
to set the LFE gain to 6 – the twelve o’clock position – and then use
the home theatre processor’s level control to dial in the level. However,
different locations in the room may have different room gain in the bass
frequencies. The LFE gain control allows you to tune each subwoofer
for optimum balance.
LFE Output
Along with the LFE input, the S2/12t has the unique capability of
providing an LFE output. This buffered output can be used to daisy-
chain the LFE signal from the S2/12t to the LFE inputs of other
Genesis subwoofers including other S2/12t’s, S4/8’s or G928’s. Thus,
it is possible to channel the LFE signal from your home theatre
processor to one S2/12t, and then from that to another, and another,
and another!
You can even use BOTH single-ended RCA and balanced XLR LFE
outputs to daisy-chain even more subwoofers when either the single-
ended input or the balanced input is used.
In the case of LFE, using more low frequency sources (not higher
level) is better than using less. The point is not to achieve a higher
level of bass response but rather, by using multiple subwoofers to
distribute the LFE signal around the room, dramatically reducing and
evening-out room modes and increasing the bass capability of the
system.
Distributing low frequency information is also helpful for reproduction of
Multi-channel Music because you get incredible articulation and detail
in the bass all around the room.
Power
Make sure the ServoSub 2/12t is plugged into a wall outlet that is
always on. The S2/12t has an auto-on feature and will automatically
power up from “stand-by” when it detects a signal, and will switch itself
off after about 10 minutes of being idle.
We recommend against the use of an extension cord for providing AC
power. If you are forced to use an extension cord, make certain that it
is as heavy duty (a minimum wire thickness of 12 gauge), an extension
cord as you can find. The S2/12t running at full tilt can draw up to
