balancing circuit that enables the power amplifier to drive the
balanced input of the servo amplifier. Because of the extremely
high impedance of the balancing circuit, the parallel connection
places absolutely no stress on the power amplifier.
Do not use any
other interconnect cable for this purpose as the high level output
from your power amplifier will blow the input circuit of the Control
Module!
This internal circuit also allows even fully balanced power
amplifiers
*
to be connected this way.
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 coherence and good integration between the
midrange and bass is much harder to achieve.
Servo-Bass Amplifier Remote
Your Genesis 2.2 servo-bass amplifier is supplied with a Logitech
Harmony™ remote control. This is a universal remote control that
can also be programmed to control the rest of your music system.
While we do not provide customer support for the programmable
functions (please check
www.harmonyremote.com
for that) we
supply it pre-programmed with the correct codes to control the
*
Do NOT use this method of connection with Class D power amplifiers that have both +ve
and –ve speaker outputs floating above ground. Some of these amplifiers have as much
as 36V on their speaker “ground”, and this will damage the Servo-Controlled Bass
Amplifier. Use the second method of connection.
