QXPA User Manual
VHF Wireless Microphones
Extend the 2 VHF antennas at the rear of the unit (these are detachable when not in use
)
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
contacts inside the microphone body, taking care to observe the correct polarity.
Turn the VHF VOL control clockwise part way.
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 the VHF VOL control, 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 an echo function for singing and special
effects. The time parameter of this effect can be adjusted using the DELAY control.
The microphone section has a dedicated CONTOUR control to tailor the tonal character of the
microphones. Turning clockwise increases the mid frequency content, giving a more
pronounced tone to the microphones for increased prominence in the mix. Turning the
CONTOUR control anti-clockwise reduces the mid frequency content, giving the microphones a
less obtrusive tone for a softer position within the mix.
Master BASS and TREBLE can be cut by turning the relevant control anti-clockwise or boosted
by turning clockwise. When not in use, switch the wireless microphones off.
External Inputs
In addition to the QXPA’s own VHF microphones, 6.3mm jack inputs are provided to connect
external wired or wireless microphones, which are both governed by the MIC VOL 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 stereo 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/FM player to “LINE IN”
The line input is governed by the main VOLUME control at the top of the panel.
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.
