Connecting a Subwoofer
The S4000’s MONO OUT can be used to drive a subwoofer system by engaging
the SUBWOOFER ON/OFF switch located in the MONO output strip. When the
SUBWOOFER ON/OFF switch is pressed in, the variable Low Pass filter is active.
Use the FREQUENCY control knob to set the high frequency limit of the MONO/
SUBWOOFER OUT. The mixer’s FREQUENCY control has a range from 20Hz to
200Hz, allowing you to tune the output for your subwoofer.
Check your subwoofer’s owners manual for the manufacturers recommended cut
off frequency, or use your ears while slowly sweeping the cut off point using the
FREQUENCY control knob to find the correct setting for your system.
