Operating instructions
Connecting the receiver and operating system:
1. Push and turn the antenna plug in to the antenna socket on the front of the receiver, repeat for second
antenna. Point both antennas upwards in a vertical position.
2. Ensure your mixer/amplifier is turned down before connecting the receiver.
3. Connect the receiver using the Mix output with the supplied 1/4 inch TRS (unbalanced) lead.
This should go to the
MIC IN
on your mixer or amplifier. Control of individual microphone channel levels
is via the individual channel volume controls on the front of the receiver. Alternatively, if you are using a
multi-channel mixer, you can connect the receiver using the individual channel outputs using XLR
(balanced) leads (not supplied).
4. Plug the DC power adaptor into the DC socket on the rear of the receiver. Plug the other end in to
a suitable AC outlet.
5. Press the power switch on the front panel of the receiver to
I
. All four channel power indicator LEDs
should light red.
6. Ensure all the channel volume controls are turned down to minimum. Turn your chosen microphone
on using the power switch. The LED status indicator will flash red briefly to indicate it is
ON
.
7. When a microphone is turned on the status LED on the corresponding channel on the receiver will
also light up. The radio frequency (RF) indicator will turn yellow to show a signal is being received from
the microphone. The audio frequency (AF) indicator will turn green to show audio is being received
(i.e. it will pulse with your voice as you speak in to the microphone).
8. Turn the microphone power switch to mute or
OFF
when you have finished speaking/singing in to the
microphone and before you place it down on a table.
The receiver has 4 separate volume controls, one for each microphone. Use this in conjunction with the
controls on your mixer/amplifier to adjust the sound level required. If the sound is distorted check the
volume level controls on the receiver and the mixer/amplifier. If sound continues to be distorted move
the microphone further away from your mouth and also check the battery is fully charged.
The receiver can be mounted in to a standard 19” rack mount case/rack using the supplied rack-mount
brackets. Fix one of these to each side of the receiver using the supplied screws, and then fit the unit in
to your rack. The microphones have a maximum effective range of around 100m, depending on the
environment in which the system is being used. This can be reduced to 60m in many situations. If the
sound becomes intermittent move the microphones closer to the receiver. Interference is occasionally
possible when the distance between a microphone and the receiver is less than 1.5m. To achieve the
best possible system performance, please keep the microphones at least 1.5m away from the receiver.
Also, for optimum reception, extend the antenna fully and orientate vertically. Reception maybe
impaired by obstacles between the transmitter and receiver. High power electrical equipment can
cause unwanted interference.
Troubleshooting:
Problem
Possible cause
Solution
Receiver – no sound
Power button is in the OFF position. DC power adapter
is not plugged in
Turn on the power button plug in the power adapter
Receiver – no LED
Microphone - no sound
but LED indicators are lit
Mic transmitter is out of range. Mic is switched off. Mic
volume it turned down. Batteries in mic are not installed
properly. Receiver is not connected to an amp or mixer.
Ensure that the mic is within range. Turn on the mic switch.
Turn up the mic volume on the receiver. Reinstall or use new
batteries. Connect an output cable to an amp or mixer
Distorted sound or feedback
The 4 mics may be too close together. Batteries are running
out of charge. Mic volume may be too high. Possible
interference from another source.
Increase the distance between mics. Replace the batteries.
Reduce the volume. Move the system away from other
electric sources.
