Rear Panel Layout

The rear panel features a comprehensive array of inputs, outputs, and controls. The following numbered components are present:

Power Input: 220-240Vac, 50/60Hz, 80VA.

Safety Markings: CE and UKCA logos are present. A fuse rating of FUSE FIAL 250V is indicated. A warning states: "CAUTION: DO NOT OPEN. NO USER SERVICEABLE PARTS INSIDE."

Connection and Power Up

Connection

Your new QTX QR-series portable PA unit may arrive 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 charge in the battery. If it is red, then 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

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.

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 mp3 player. To use these, set the MODE switch on the media 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 Media Player

The QRPA unit has an inbuilt media player with USB/SD playback, FM tuner and Line input. Panel controls are detailed below:

Media Player Controls

The following controls are available on the panel:

• MODE: Switches music input between USB/SD player, FM tuner and Line In.
• ◄ / VOL-: Momentary press for previous track; hold to decrease volume.
• ► / VOL+: Momentary press for next track; hold to increase volume.
• RPT: Toggle between repeating all, single, or no tracks.
• ►II: Play / pause track.

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 shows Line In or an FM frequency, 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 VOLUME control should result in the media being played through the speaker.

In FM tuner mode, the display will show the frequency of the current station.

Pressing and holding the ►II button for 3 seconds initiates auto-tuning, which stores all the strongest detected FM radio stations into internal memories. The stored stations can then be navigated using the ◄ and ► buttons.

Remote Control

An infra-red remote control is provided for the media player, offering additional functions for greater control. To operate the remote, remove the clear plastic tab from the remote to activate the battery.

The remote control includes buttons for:

• Media player on/off
• Mode select
• Mute
• Transport controls (Play/Pause, Next, Previous)
• Volume down / up
• EQ preset select
• USB or SD select
• Repeat mode
• Numerical track select (0-9)

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.

When charging, the CHARGE LED will light orange. When fully charged, the CHARGE LED will light green.

Note: It is recommended to store the PA unit at an ambient temperature and not with the battery fully discharged.
