Operation

With VOLUME turned down and power switch off, connect the IEC or Fig.8 lead to an appropriate mains outlet.

Connect output of mixer or any line level signal to the INPUT via 6.3mm jack or XLR.

If the signal is to continue to further active speakers, connect these from the OUTPUT line level XLR.

BASS and TREBLE controls should remain pointing vertically (12-o-clock position).

Press the power switch on and gradually increase the VOLUME until the input signal is heard through the speaker.

Your QR active speaker should now be ready to operate.
