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.
Connect the twin aerials 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 handheld mic in turn
– the RF A and RF B LEDs should light as a result.
The LED on each mic will light momentarily and then go out
– this is normal.
If the LED does not light or stays lit, change the battery.
Gradually increase VOL A and VOL B, 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 handheld microphones off.
External Inputs
In addition to the unit’s own VHF microphones, a pair of 6.3mm jack inputs are provided to connect 2 external wired
or wireless microphones, which are both governed by the MIC VOLUME control.
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.
