Connection
Your new QRPA unit may arrive with you with the internal battery charged. Before connecting to the mains, switch the unit on and check the POWER LED. If it is green, there is a charge in the battery. If it is red, then you will need to charge the battery before using it away from a mains supply (see “Charging the battery” below) Connect the QRPA unit to the mains using the appropriate mains IEC lead supplied. You may otherwise opt to connect the spring terminals at the rear to an external 12Vdc supply, such as a car battery, or use the internal battery if charged.
Charging the battery
When not in use but connected to the mains, if the POWER switch (19) 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 will light orange when charging. When fully charged, the CHARGE LED will change to green. Note: it is recommended to store the PA unit at an ambient temperature and not with the battery fully discharged

Power Up
Turn the VOLUME, ECHO, VHF, and MIC VOLUME controls down (anti-clockwise) and turn the POWER switch on (the power LED should light).
BASS and TREBLE controls should remain to point vertically (12-o-clock position).
Switch the “Talk Over Ctrl” off (i.e. press the button so that it is in the out position)
Your QRPA unit should now be ready to operate.
VHF Wireless Microphones
Insert the supplied AA batteries into the handheld microphones by carefully unscrewing the base of each and connecting the “+” and “-” terminals of the battery to the corresponding clips inside the microphone body, taking care to observe the correct polarity.
Connect each antenna to the connectors at the rear and extend them fully at an angle.
Switch on each wireless mic by turning up its volume control – the RF LEDs should light. If the LED on the transmitter lights dimly, change the battery.
Gradually increase VHF volume controls, testing each mic 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 a pre-set echo function for singing and special effects. BASS and TREBLE can be cut by turning anti- clockwise or boosted by turning clockwise.
In addition, the wireless microphones have a CONTOUR control, which adjusts the mid-tone character of both microphones. This can vary in how prominent they are in the mix.
When not in use, switch the VHF wireless microphones off.
External Inputs
In addition to the unit’s own VHF microphones, 6.3mm jack inputs are provided to connect externally wired (or additional wireless) microphones, which are both governed by the MIC VOLUME control.
Mic 1 input jack can also accept a guitar input instead of a microphone if required.
The music level can be automatically muted when speaking into a microphone by pressing the “Talk Over Ctrl” button. Any audio from the internal media player will be reduced in volume when a sound is detected from the microphones and return to normal volume when there is no sound from the microphones, allowing announcements to override playback.

Internal media player
At the top of the rear panel is the media player section, which can provide playback of recorded material internally or from external sources. Controls for this are shown below.
MODE Select player mode between USB, SD, FM tuner, or Bluetooth
SD/USB For mp3 media, select between USB or SD/MMC memory device
Previous track / FM station
Next track / FM station
Repeat mode: single track or all tracks
Mute media player output
Play/Pause (scan in FM tuner mode)
By default, the media player starts up in “AUX” mode, which accepts a line input via the RCA line input sockets (24) or 3.5mm jack input (11). The output level for the media player is governed by the main VOLUME control (15) or muted by pressing the MUTE button. Adjacent to the RCA line input is a twin RCA line output carrying the overall main mix for connection onto further recording or PA equipment.

FM Tuner
Press the MODE button until the media player is in “FM tuner” mode. The display will show the radio frequency that the media player is tuned to.
To tune the FM radio to available stations in the reception area, press and hold the PLAY/PAUSE button for 3 seconds, and the media player will scan all available stations and
store them as numbered presets. These can then be selected using the PREVIOUS and NEXT buttons.
USB/SD player
Insert a USB memory stick or an SD/MMC card with mp3 or WMA media stored on it into the USB port or SD card slot and the media player can enter another mode. Pressing the MODE button will now toggle between AUX, FM tuner, and USB/SD playback.
Files on the USB or SD device must be mp3 or WMA format for the media player to read them.
PLAY/PAUSE, PREVIOUS and NEXT buttons control playback and track navigation.
If both USB and SD/MMC media are connected, the USB/SD button will toggle between these.
Pressing the REPEAT button will toggle between 2 repeat play modes.
“RPT ONE” repeats the current track and “RPT ALL” repeats all tracks in the current folder.
Bluetooth wireless pairing connection
T o connect a smartphone or tablet to the media player for wireless playback, select the Bluetooth mode on the media player, enable Bluetooth wireless pairing on the sending device, and scan for available devices. The Bluetooth ID for the media player is “PA SYSTEM”.
Select to pair the device and connect with the media player. Playback of tracks on the sending device should be heard through the speaker. PLAY/PAUSE, PREVIOUS and NEXT buttons will also send control signals back to the sending device for track control and navigation.
Bluetooth connection has a range of 5-8m. When the sending device is out of range, the connection will be lost and will need to be connected again once back within range.
Remote control
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. Point the remote control towards the media player display to operate.
