Krell Industries MASTER REFERENCE SUBWOOFER Owner's Reference Manual page 37

Connections and Configurations
The remote control is the main input device for the Master Reference Subwoofer.
All initial setup and subsequent system configuration adjustments must be made
through the remote control or via the RS-232 port.
For maximum performance, the Master Reference Subwoofer must be connected
to other components in the system via the appropriate CAST, balanced, or single-
ended inputs and outputs; connected for stereo and low frequency effect; and the
low-pass and high-pass filters configured to fit your system.
Step I.
Choose the Connections
This section discusses the CAST, balanced, and single-ended connections that are
available on the Master Reference Subwoofer, explains switching between CAST
and balanced inputs, and lists factory defaults.
CAST and Balanced Connections
Krell recommends using its proprietary Krell CAST system for unparalleled sonic
performance for connections between the Master Reference Subwoofer and other
CAST-equipped components. The Master Reference Subwoofer also offers balanced
and single-ended operation.
IMPORTANT
Connecting non-CAST components to CAST inputs or outputs can damage your
equipment and void your warranty.
Do not attempt to change CAST cable terminations or CAST inputs or outputs to
RCA or XLR connectors. It is electrically impossible to convert CAST input or
output connections for balanced or single-ended voltage operation.
Please read the Warranty, on pages 50-51, to understand the warranty limitations of
the Master Reference Subwoofer.
