To connect to differential (balanced output) power amplifiers using the
BALANCED high level input
To engage the Neutrik Speakon plug, insert fully into socket and rotate clockwise until locked.
To remove the Neutrik Speakon plug, grip body of plug, place thumb on chrome lever, move
lever backwards rotate plug anti-clockwise (counter-clockwise in the US) quarter turn and
withdraw.
The high level balanced input is also single channel and is designed to take the high level
output from the speaker terminals of differential output (bridged mode) amplifiers. Because
the intention of using separate bridged amplifiers is to ensure entirely separate signal paths
for both channels, two separate Sub-Bass Systems are required for your system to reach its
optimum potential, one for each channel.
A differential amplifier does not have to be a mono amplifier, or one that has balanced inputs.
There are a number of stereo integrated and basic amplifiers that are differential.The output
topology of the amplifier should be checked before connection to the Sub Bass System is
made, if this is not clear from the amplifier user manual then consult the manufacturer.

High Level connections should be made to the same binding posts as the main speakers
Note:
Monoblock amplifiers may or may not be bridged output. See the manufacturers
documentation for your amplifier if you are uncertain.
The BLACK should be connected to ground at the pre-amplifier. If the pre amplifier does not
have a ground terminal, then use one of the chassis screws at the rear of the pre-amplifier or
amplifier.
The output level is adjusted using the control marked HI LEVEL
