Controls

Operation and Connection

Your new QTX QR-series 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 (see “Charging the battery” below)

Connect the QR-series portable PA 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.

Power Up

Turn the VOLUME, ECHO and MIC 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).

Switch VCV (voice controlled volume) off.

Your QR-series PA unit should now be ready to operate.

VHF Wireless Microphones

For QR12PA and QR15PA, 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 clips inside the microphone body, taking care to observe the correct polarity.

For QR10PA, connect the neckband microphone to the bodypack, slide open the bodypack and insert the supplied 9V battery, again observing the correct polarity.

Connect the antennae to the connectors at the rear and extend them fully at an angle.

With the VOL A and VOL B controls turned down, press the VHF ON/OFF button in so that the VHF POWER LED lights.

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 VOL controls, 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 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 wireless microphones off.

External Inputs

In addition to the unit’s own VHF microphones, 6.3mm jack inputs are provided to connect external wired or wireless microphones, which are both governed by the MIC VOLUME 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 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 player to “LINE IN”

Adjacent to this twin RCA input is a twin RCA line output carrying the overall main mix.

The AUX is governed by the VOLUME control at the top of the panel.

Internal USB/SD player

Insert a USB memory stick or an SD card with mp3 or wma media stored on it into the relevant slot on the rear panel.

If the LCD display reads “LINE IN”, press the MP3/LINE 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 media being played through the speaker.

Panel controls are detailed below…

“MP3/LINE” switches music input between internal USB/SD player and AUX input
“VOL – “ press and hold to decrease volume
“I<<” momentary press for previous track
“VOL +” press and hold to increase volume
“>>I” momentary press for next track
“REPEAT” toggle between repeating all, single or no tracks
“>II” Play / pause track

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.

Charging The Battery

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. When fully charged, the CHARGE LED will no longer be lit.
