Powering 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 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 mic 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
"hear"
speaker so that it doesn't
the speaker output.
Turning the ECHO control clockwise introduces a pre-set echo function for singing and special
effects. BASS or 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 Talk-over 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 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.
