VHF Wireless Microphones
The QX8PAV has a built-in dual VHF receiver and is supplied with 2 x handheld
wireless microphones. Each handheld microphone will need to be loaded with a
9V battery (supplied) before use by carefully unscrewing the base of each and
connecting the “+” and “-” terminals of the battery to the corresponding contacts
inside the microphone body, taking care to observe the correct polarity.
Turn the VHF VOL A and VHF VOL B controls (9, 25) part way up (clockwise).
Antennas are fixed inside the speaker and do not need to be extended.
Switch on each microphone by sliding the upper switch (labelled “OFF – PWR”) to
the right. The LED below the switch should light and the RF LEDs on the main
unit (11, 12) should also light to indicate that carrier signals are being received.
If the “LOW – BATT” LED on the transmitter lights, change the battery.
Slide the lower switch (“ON – MUTE”) upwards to the ON position.
Gradually increase the VHF VOL A and B controls, testing each microphone in
turn for output through the speakers. The VHF microphone volumes are not
affected by the main volume control on the rear panel. Take care not to incur
“feedback” (howling or screeching sound through the speaker) by keeping the
microphone a sensible distance from each speaker and pointing away from the
speakers so that it doesn’t
hear
its own output.
Turning the ECHO control (7) clockwise introduces an echo for singing and special effects. The
time parameter of this effect can be adjusted using the DELAY (8) control. If required, the
music level can be automatically muted when speaking into a mic by switching the VCV on (31).
When not in use, switch the wireless microphones off and remove the batteries if storing the
microphones for long periods.
External Inputs
In addition to the QX8PAV’s own VHF microphones, two 6.3mm jack inputs (30, 32) are
provided for connecting external wired or wireless microphones, which are both governed by
the MIC VOL control (10). For guitarists, MIC 1 input can accept a guitar input instead of a mic.
A 3.5mm stereo jack (33) and twin RCA inputs (34) are provided for an Auxiliary line input
source such as a CD player or smartphone. To use these instead of the built-in media player,
press the DVD/AUX switch in (to select AUX). The AUX input is governed by the main VOLUME
control at the top of the panel. BASS and TREBLE (22, 6) can be cut by turning either control
anti-clockwise or boosted by turning clockwise.
Below the twin RCA input is a twin RCA line output carrying the overall main mix. This can be
fed on to further active speakers or portable PA units via a twin RCA lead.
