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 .
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.
