1.Turn ON the [LPF] switch on the EMX5000 front panel.
2. Set the crossover frequency with the adjacent knob to around 100hz.
3. Connect the 1/4 in MONO line level output jack to the input of an external amplifier with instrument cable (not speaker cable). The MONO master fader will control the mixers overall mono out signal for the subwoofer.
Note: TheLPF filter removes the high frequency component from the monooutput but does not remove the low frequencies from the stereo output.
