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. 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 power adaptor. You may otherwise opt to connect the DC input jack 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 recharged 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.

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 the handheld microphone by carefully unscrewing the base 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 up (clockwise) part way

Switch on the wireless mic – the RF LED should light as a result. If the LED on the transmitter lights dimly, change the battery. Gradually increase the VHF VOL control, testing the 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 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.

When not in use, switch the beltpack transmitter off and remove the batteries if not being used for long periods.

External Inputs

In addition to the QRPABT’s own VHF microphone, 6.3mm jack inputs are provided to connect external wired or wireless microphones, which are both governed by the MIC VOL control.

Also, twin RCA and 3.5mm stereo jack input are provided for line input sources such as CD player or smart phone. To use these. 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.

VCV

The VCV button (15) activates a muting function which causes playback from the internal media player to be temporarily reduced in level when there is input from a microphone. This can be useful to “duck” music playback when making announcements.

Internal USB/SD player & Bluetooth receiver

The DELTA-50 onboard media player 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, 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 button or try removing and re-inserting the memory device.

Increasing the Master Volume control (21) should result in the audio being played through the speakers.
Panel controls are detailed below…

MODE: switches input between USB/SD/FM media or Bluetooth
press for previous track
press for next track
Repeat mode
Play/Pause playback

To connect a smart phone or other Bluetooth device to the DELTA-50 media player, open the Bluetooth menu on your device and search for “PA SYSTEM”. Pair with this ID and connect (re-name if desired) in order to be able to play audio from the Bluetooth device to the DELTA-50.
Pressing the MODE button will select between FM, Bluetooth and USB/SD playback sources.
(Note: there is also an AUX setting which is not used, since the mixer section  has separate line inputs)

Mute, 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 operate, remove the clear plastic tab from the remote to activate the battery.
