Connection
Your new QTX QR-series portable PA unit may arrive with you with the internal
battery fully 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, an AUX twin RCA input is provided for line input sources such as CD player or
ipod.
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
