Powering up
Your new QRPABT unit may arrive with you with the internal battery charged. Before connecting to the mains with the supplied power adaptor, switch the unit on and check the POWER LED (18). If it is green, there is charge in the battery. If it is red, then you will need to charge the battery before using away from a mains supply.
Connect the QRPABT unit to the mains using the supplied IEC mains lead (22). You may otherwise opt to connect the DC input jack (21) to an external 12-15Vdc supply, such as a car battery, or use the internal battery if charged.
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 (18), 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.
Initial setup
Turn all VOLUME & ECHO 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 main VOLUME control part way and switch VCV off. Your QRPABT unit should now be ready to operate.
VHF Microphone
Insert the supplied AA batteries into each of the handheld microphones by carefully unscrewing the base and connecting the "+" and "-" terminals of the battery to the corresponding contacts inside the microphone body, taking care to observe the correct polarity. Turn on the VHF receiver (16) and turn the VHF VOL controls (6) up (clockwise) part way.
Switch on each wireless mic in turn – the rear panel RF LEDs should light as a result. If the LED on the transmitter lights dimly, change the battery. Gradually increase the VHF VOL controls (6), testing each microphone 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.
Turning the ECHO control (4) clockwise introduces a pre-set echo function for singing and special effects. BASS and TREBLE (15, 3) can be cut by turning anti-clockwise or boosted by turning clockwise.
When not in use, switch the handheld transmitters off and remove the batteries if not being used for long periods.
External Inputs
In addition to the QRPABT's own VHF microphones, a pair of 6.3mm jack inputs (8) are provided to connect external wired or wireless microphones, which are both governed by the MIC VOL control (5).
(MIC 1 can also accept an electric guitar input).
Twin RCA (7) and a 3.5mm stereo AUX (9) input are provided for line input sources such as CD player or smart phone. Adjacent to the twin RCA input is a twin RCA line output (17) carrying the overall main mix.
This can be fed on to further active speakers or portable PA units via a twin RCA lead.
VCV
The VCV button (14) activates a Voice-Controlled Volume function which causes the media player to be temporarily muted when there is audio input from a microphone. This can be useful to "duck" music when making announcements.
Internal USB/SD player & Bluetooth receiver
The QRPABT onboard media player (11) can play back files from USB/SD/FM media or a paired Bluetooth device. Insert a USB memory stick or an SD card with compressed digital audio files stored on it into the relevant slot on the top panel. Playback will normally start automatically from the last media inserted (USB or SD).
If the LCD display shows a jack plug (AUX), press the MODE 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 Master Volume control (13) should result in the audio being played through the speakers. Rear panel controls for the media player (12) are detailed below...
MODE switches input between USB/SD/FM media or Bluetooth
press for previous track (hold for volume -)
▶▶ press for next track (hold for volume +)
REC Press to record audio to media
▶II Play/Pause playback or FM scan (hold to pair for TWS)
Pressing the REC button initiates recording of external inputs to any inserted USB or SD media as a .wav file. Pressing REC again will stop the recording. These tracks can be played back from USB/SD in the same way as mp3 files.
In FM mode, press and hold the ▶II button to initiate automatic scan of available radio stations, which are then stored to memory as channels in order of frequency. Once completed, use ◀ and ▶I buttons to step through saved radio stations.
To connect a smart phone or other Bluetooth device to the QRPABT media player, open the Bluetooth menu on your device and search for the QRPABT unit, which is simply called "bluetooth". Pair with this ID and connect to play audio from the Bluetooth device through the QRPABT unit.
TWS (True Wireless Stereo) can be activated if 2 of the same QRPABT are operated in Bluetooth range of each other. Switch both units on and before pairing any phone, set each to Bluetooth and press and hold Play. The LED is normally blue flashing before pairing, solid blue when paired, red flashing when TWS pairing, solid red when TWS paired. Pair the master unit to a smartphone and this will play the left channel, whereas the other QRPABT will play the right channel.
Pressing the MODE button will select between FM, Bluetooth & USB/SD playback.
Volume and track navigation can be achieved via the media player control panel. Bluetooth pairing is always available for a single device so long as the device is within reception range. It may be necessary to re-connect if the device has moved out of range and disconnected.
In addition to the panel controls, an infra-red remote control is provided for the media player which adds some further functions to allow greater control over the media player.
To use the remote, remove the clear plastic tab to activate the battery.
