1.4Servo-controlled Bass Amplifier Connections

The way that the Servo Controlled Bass (SCB) amplifier is connected to the rest of your system will largely determine the coherency of the bass to the midrange. However, no one method will work with all systems. The first big problem is that no power amplifier is “straight wire with gain”. The second problem is that interconnects and speaker cables are not perfect conductors.

Hence, the Genesis 1.1 provides for two different methods of connection.

1)Each SCB amp has two input connectors, unbalanced RCA and balanced XLR. Either connection can be used but not both. This is the simplest way, to connect either the RCA or XLR input of the SCB amplifier to the output of your preamplifier. Use the same quality interconnect as you would for the main pre-amplifier to power amplifier interface. Bass is the foundation of music, and it may be difficult to integrate the bass to the midrange if there is a significant quality difference in the interconnection.

If your preamplifier has only one set of outputs, you may have to invest in a good-quality Y-connector (either RCA or XLR), or commission a special Y-cable from your preferred interconnect provider. However, if your preamplifier has two sets of outputs, use one for driving the power amplifier that will drive the midrange/ tweeter and use the other output for the SCB amplifier.

A problem with this method is that if the power amplifier used shifts phase significantly between its input and output (it may be phase coherent at its output), the midrange/tweeters may be out of phase with the woofers.

2)Alternatively, a cable (the Servo-Bass Interconnect) is provided that will enable the high-level output of the midrange/tweeter power amplifier to drive the SCB amplifier. This has a Neutrik XLR connector at one end, and bare wire at the other end. Within the Neutrik connector is a balancing and attenuation circuit that allows this connection to work with most (but not all) power amplifiers.
