Portability
For transport purposes, the QX8PAV main unit has a retractable handle and wheels. The
satellite speaker can be stacked on top of the main unit (ensuring that the feet locate onto the
posts at the top of the main unit) and a strap is provided to secure the satellite speaker to the
extended handle, allowing the whole set to be rolled as a trolley.
Care should be taken to avoid uneven terrain or dragging the trolley too quickly, which may
damage the wheels or cause the set to overbalance.

Setting up
The QX8PAV set is based around a main portable PA unit and a satellite speaker. Each can be
free standing or mounted onto 35mmØ speaker poles. Open the rear panel on the satellite unit
by removing the 4 thumb screws and use the speaker jack lead inside to connect the 6.3mm
input on the satellite to the Speaker Out jack (16) on the main unit. The rear cover may then
be put back onto the satellite cabinet if required. There is space inside the rear compartment
for other accessories, such as microphones, leads and the remote handset.
Charging the battery and powering up
Your new QX8PAV main unit may arrive with you with the internal battery charged. Before
connecting to the mains, switch the unit on and see if the power LED (13) lights green.
If this LED shows red or is not lit, you will need to charge the battery before using away from a
mains supply.
There is a power adaptor supplied which connects to the main unit via the DC power adaptor
inlet (15). This inlet can also be powered from another 12-15Vdc source, such as a car battery.
When connected to the mains via the power adaptor, if the main power on/off switch (29) is in
the OFF position, the internal battery will be re-charged from the mains supply. This can be
observed by the charging LED (below the power LED) which lights orange when charging.
When the battery is full, this LED will change to green.
To power the main unit up, start with all rotary controls turned down (anti-clockwise) and turn
the POWER switch on (the power LED should light). Turn BASS and TREBLE controls to point
vertically (12-o-clock position). Turn up the main Volume (23) control part way and switch VCV
(voice controlled volume) off. Your QX8PAV set should now be ready to operate.
Media Player
The QX8PAV has many different options for input sources and it is useful to set the controls
initially using the internal media player. Ensure that the DVD/aux switch is in the “out” position
(labelled “DVD”) and either insert a CD, compressed audio disc, CD+G or DVD disc into the disc
slot (21). The mechanism should automatically feed the disc into the player. Alternatively, plug
in a USB memory stick containing compressed audio media into the USB port (3). If playback
does not begin automatically, press the Play button (18) and check for playback through both
speakers.
If the disc is for video playback, such as DVD or CD+G, connect an RCA video lead from the
Video Out connector (17) to a TV or display with composite video input and check that the
video is playing correctly.
For reference, the disc player has priority over the USB port and so the media player will search
for a disc before switching to USB. The output level of the media player is adjusted via the main
Volume control (23)

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.

Bluetooth™ Connection
The QX8PAV unit is fitted with a Bluetooth receiver, which is operated via a rotary control (28)
and play button (27) on the rear panel. When the rotary control is turned fully off, power to the
Bluetooth receiver is off.
If switched off, turn the Bluetooth rotary control clockwise to switch power on to the Bluetooth
receiver. Turning the rotary control up increases Bluetooth output level –halfway is a
reasonable position to start.
Press and hold the Bluetooth play button for 5 seconds and the Bluetooth indicator (26) will
flash blue. If the playback source is already paired, the connection will be made with the
QX8PAV and a chime will sound to confirm this.
If not paired, press the play button briefly again to see the LED flash between blue and red.
At this point, the Bluetooth receiver is made visible to all Bluetooth devices in range.
Scan for Bluetooth devices on your playback source and check for a device called “bluetooth”
(lower case). Select this device and opt to connect and your sending device should state that it
is connected to “bluetooth” for audio output and the LED should flash blue and a beep will
confirm the pairing.
Play audio from your sending device and check for output through the QX8PAV speakers.
If there is no output from Bluetooth, check if there is more than one device in range called
“bluetooth”
In the eventuality that more than one device is called “bluetooth”, try each device in turn until
the QX8PAV main unit is found. Check also that the volume level is turned up on the sending
device.
Once audio is playing through the speakers from Bluetooth, adjust the rotary control (28) to the
required volume.
The QX8PAV Bluetooth receiver has duplex Play/Pause control over the sending device.
Press the Bluetooth button on the rear panel to remotely pause or resume playback from the
sending device. This is useful when the audio is played from a phone in a pocket or on an
armband or from a PC or Mac computer.
Bluetooth on the QX8PAV can only pair to a single device at any one time and should be
operable over a range of 5 to 8 metres.
Turning the rotary control fully down clicks the power off and shuts down the Bluetooth
receiver.
