Setup & Operation
With INPUT LEVEL turned fully down and power switch off, connect the IEC to an appropriate
mains outlet.
Connect output of mixer or any line level signal to the INPUT via XLR. If the signal is to
continue to further active speakers, connect these from the THRU line level XLR.
Begin with the FREQUENCY control in the mid position (12-o-clock position)
Press the power switch on and gradually increase the INPUT LEVEL until the bass signal is
heard through the speaker.
Turning the FREQUENCY control up will include more mid frequencies and turning it down will
eliminate all but the lowest frequencies. Adjust the FREQUENCY control to the desired tone,
noting that lower settings may need the INPUT LEVEL turning up to compensate for the
narrower frequency band.
The PHASE switch can help eliminate speakers which are “out phase” from - -of cancelling each
other’s signals out. The correct setting for this switch is whichever setting gives the loudest
output by a process of trial and error. One or other setting may also help to avoid feedback. –
If there is no difference in volume or feedback, leave the switch in the “0°” position (out)
To avoid loud noises when powering down, turn down the OUTPUT LEVEL before switching
off .
