Powering up
Your new QXPA portable PA 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 lights. If not, you will
need to charge the battery before using away from a mains supply.
When not in use but connected to the mains, if the POWER switch is in the OFF position, the
internal battery will be re-charged from the mains supply. This can be observed by the
CHARGE LED which lights when charging. Connect the QXPA portable PA unit to the mains
using the appropriate mains IEC lead supplied. You may otherwise opt to connect the DC input
at the rear to an external 12Vdc supply (e.g car battery) or use the internal battery if charged.
Turn the VOLUME controls down (anti-clockwise) and turn the POWER switch on (the power
LED should light). BASS and TREBLE controls should remain pointing vertically (12-o-clock
position). Turn up the VOLUME control part way and switch VCV (voice controlled volume) off.
Your QXPA unit should now be ready to operate.

VHF Wireless Microphones
Extend the 2 VHF antennas at the rear of the unit (these are detachable when not in use)
Insert the supplied 9V batteries into the handheld microphones by carefully unscrewing the
base of each and connecting the “+” and “-” terminals or the battery to the corresponding
contacts inside the microphone body, taking care to observe the correct polarity.
Turn the VHF VOL control clockwise part way.
Switch on each wireless mic in turn – the RF LEDs should light as a result. If the LED on the
transmitter lights dimly, change the battery. Gradually increase the VHF VOL control, testing
each microphone in turn for output through the speaker. Take care not to incur “feedback”
(howling or screeching sound through the speaker) by keeping the microphone a sensible
distance from the speaker and pointing away from the speaker so that it doesn’t
hear
the
speaker output.
Turning the ECHO control clockwise introduces an echo function for singing and special
effects. The time parameter of this effect can be adjusted using the DELAY control.
The microphone section has a dedicated CONTOUR control to tailor the tonal character of the
microphones. Turning clockwise increases the mid frequency content, giving a more
pronounced tone to the microphones for increased prominence in the mix. Turning the
CONTOUR control anti-clockwise reduces the mid frequency content, giving the microphones a
less obtrusive tone for a softer position within the mix.
Master BASS and TREBLE can be cut by turning the relevant control anti-clockwise or boosted
by turning clockwise. When not in use, switch the wireless microphones off.
External Inputs
In addition to the QXPA’s own VHF microphones, 6.3mm jack inputs are provided to connect
external wired or wireless microphones, which are both governed by the MIC VOL control.
If required, the music level can be automatically muted when speaking into a microphone by
switching the VCV on.
Also, twin RCA and 3.5mm stereo jack input are provided for line input sources such as CD
player or ipod. To use these, set the MODE switch on the USB/SD/FM player to “LINE IN”
The line input is governed by the main VOLUME control at the top of the panel.
Adjacent to 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.

Numerical track/memory access buttons
Insert a USB memory stick or an SD card with compressed digital audio files stored on it into
the relevant slot on the rear panel.
If the LCD display reads “LINE IN”, press the USB/SD button and check that the LCD display
shows that media is being read from the USB or SD device. If not, press the “>II” button or
try removing and re-inserting the memory device.
Increasing the VOLUME control should result in the audio being played through the speaker.
Panel controls are detailed below…
“MODE” switches input between internal USB/SD/FM and AUX input
“VOL – “ press and hold to decrease volume
“I<<” momentary press for previous track / FM station
“VOL +” press and hold to increase volume
“>>I” momentary press for next track / FM station
“REC” Enter record mode
“>II” Play / pause track – hold for auto channel search in FM mode
In addition to the panel controls, an infra-red remote control is provided for the USB/SD player
which adds some further functions to allow greater control over the media player. To operate,
remove the clear plastic tab from the remote to activate the battery.
QXPA User Manual
Bluetooth™ Connection
QXPA units are fitted with a Bluetooth receiver, which is operated via a rotary control and push
button, located on the rear panel between the VHF antennas. When the rotary control is
turned fully off (anticlockwise), the 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 button for 3 seconds and the LED will light.
Press 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 phone or other audio player and check for a device called
“Bluetooth”. Select this device and opt to connect and your phone or other Bluetooth device
should state that it is connected to “Bluetooth” for audio output and the LED should stay single
colour. Play audio from your phone or other Bluetooth device and check for output through the
QXPA
If there is no output, 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 QXPA is found. Check also that the volume level is turned up on the sending device.
Once audio is playing through the QXPA from Bluetooth, adjust the rotary control to the
required volume
The QXPA 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 QXPA 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.
