Operation

Connect the QXAV active speaker to the mains using the appropriate mains IEC lead supplied.
With the VOLUME controls down (anti-clockwise), turn the POWER switch on.
BASS and TREBLE controls should remain pointing vertically (12-o-clock position).

A 6.3mm jack or XLR line input is provided to connect a line input. This can accept balanced or
unbalanced line level signal. Tone shaping is available by adjusting the BASS and TREBLE
controls and master level is governed by the VOLUME rotary control.
A line level output can be used to link onto other equipment via the OUTPUT XLR connector.
Ensure that volume controls are turned down before powering down and unplug from the
mains when not in use for long periods.

VHF Wireless Microphones

Insert the supplied 9V battery into the handheld microphone by carefully unscrewing the base
and connecting the “+” and “-“ terminals of the battery to the corresponding clips inside the
microphone body, taking care to observe the correct polarity. Slide open the bodypack and
insert the supplied 9V battery, again observing the correct polarity.

Connect the threaded end of the supplied 3.5mm jack lead to the bodypack transmitter and
the other (stereo) connector to a playback device or other line output source.
If preferred, the bodypack may be used with an appropriate lavalier or neckband microphone,
such as 171.855UK, 171.856UK or 171.857UK.

With the VOL A and VOL B controls turned down, press the VHF ON/OFF button in so that the
VHF POWER LED lights. Switch on each wireless transmitter in turn – the RF LEDs should light
as a result. If the LED on the transmitter lights dimly, change the battery.
Note: the switch on each transmitter has a midway MUTE position, switch fully on for testing
Gradually increase VOL control of the handheld unit, testing for output through the speaker.
