USER’S GUIDE
PRODUCT INFORMATION
The module has a Neutrik 20A PowerCon power supply input connector for its power supply and ships with a
power cord specific to the region it is purchased in. A power switch allows the module to be powered ON or OFF.
The module has 2 XLR-F input connectors: one for the subwoofer and one for the BRX308-LA tops. These
connectors are wired in parallel to XLR-M connectors to enable daisy-chaining of input signal to other systems.
There is a switch that allows for the subwoofer and tops to share the same input (INPUT Y) or use the subwoofer on
a separate signal feed (DUAL).
The module also has 2 Neutrik NL4 output connectors (labelled TOP A and Top B) for powering 2 x BRX308-LA on
each output circuit.
The processing and power module has 7 multi-color LED Indicators used to provide feedback on power, input signal
status and amplifier status.
Upon powering ON the unit, all the LED’s are lit red while the amplifiers and
DSP boot up. Once the DSP and amplifier are ready to pass audio, the
LED’s turn green.
The bottom-most LED—marked “POWER”—is lit green when the unit is
receiving power and is in the ON state.
The left 3 LEDS show the amplifier status for each of the 3 pairs of amplifier
channels that drive the SUB, TOP A and TOP B. When the LED’s are lit
green, the amplifier is in the ready state and will pass audio through to the
loudspeakers.
The LED’s light red to indicate a fault with the amplifier. Possible reasons
could be thermal shutdown and extended period of output limiting.
The LEDS on the right are used to indicate the status of input signal to each
of the 3 pairs of amplifier channels that drive the SUB, TOP A and TOP B.
Green indicates signal presence (>=-40dBu), yellow indicates the onset of
input limiting (+17dBu) while red indicates clipping (>=21dBu) of the input
signal.
It is advised to set up the gain structure so that the yellow status lights only
come on momentarily during maximum drive level from the mixer. Extended
periods of limiting and clipping of the input signal will lead to failure of the
loudspeaker components.
