Plug the XLR end of the SBI into the Control Module and the
banana plug end into the binding posts of your midrange/tweeter
towers (preferred) or the output binding posts of your power amp.
Each end of the SBI has a grounding alligator clip on a flying green
lead. Leave this grounding clip disconnected for the time being. It
is not necessary in most instances.
The alternative method of connecting the servo-bass amplifier to
your system is to use a pair of balanced interconnects (not
supplied) from your preamplifier to the servo-bass amplifier. Your
preamplifier will need to have two sets of outputs, or you will need
to use a high-quality Y-cable (not supplied). If you use this method
of connection, your power amplifier will be driving the midrange/
tweeter towers and the servo-controlled bass amplifier will be
driven in parallel by your preamp.
As no power amplifier is “straight wire with gain”, we do not
recommend this way of driving your servo-bass amplifier. The
reason is that phase coherence and integration between the
midrange and bass is much harder to achieve.
Control Adjustments
Your servo-bass amplifier should be turned on last. As a general
rule, turn your system on starting at the source to the amplifiers,
and turn it off starting at the amplifier. Plug the woofer amplifier into
a power outlet*, and using the remote control, turn it on by pressing
the POWER button. The display shows on

on .

The display flashes to identify that the function that is being

adjusted. When you first press one of the volume control

buttons, the currently-set volume will flash. The next press will

move the volume up or down. Pressing and holding the button

will move the volume up or down rapidly. The volume has a range
of 0 to 100. A volume setting of 40 is nominal, and that is a good
place to start when making adjustments. In general, a lower bass
volume setting is needed in smaller rooms.
Next, adjust the phase with the buttons marked “PHS ” or “PHS ”
on the remote control. When you first press the phase up or down
* Do NOT use any power conditioners with the Genesis Servo-Controlled Bass Amplifier.
We have found that every power conditioner that we have tried will restrict the dynamics of
the system – except the Titan by IsoTek Systems.
