Before use

The handheld microphones requires 2 x AA batteries in each microphone. Please use quality branded batteries for the best results. Ensure the batteries are fitted correctly and that the polarity is correct. The battery LED will flash when the battery power level is low.

Place the reciever on a suitable flat surface. Plug in the DC mains adaptor into the reciever. Connect the 6.35mm mono jack from the reciever into a suitable mic/mixer input.

Important note

Before you plug the DC adaptor into a suitable mains voltage supply, 240v or 110v AC. Please check the voltage input of the power supply is correct, as different countries use different voltages.

This wireless receiver has 16 available channels, each channel has 2 sub frequencies which are automatically selected by the receiver, the receiver works in the same way as a diversity radio mic system and will automatically switch between the 2 sub frequencies to obtain the best possible signal available on that channel.

You cannot manually select a sub frequency.

(A maximum of 4 transmitters should be used at any one time)

Pairing microphones to your reciever

IMPORTANT - Please read the instructions fully before you start pairing

There is a time limit to pair the microphone, if the pairing LED does not illuminate (either flashing or static) turn the handheld microphone off, then press and hold the pairing button to start the sequence again.

1. Using the dipswitches on the rear of the reciever select the desired channel to be paired with the microphone

(see chart above for frequencies ond switch settings).

2. Turn the power on to the reciever and the red power LED will illuminate.

3. Remove the battery cover from the handheld microphone.

4. Press and hold Channel 1 pairing button until the green RF LED flashes, then release the pairing button.

(while the LED is flashing) continue to step 5.

5. Hold the microphone approx 6 inches above the reciever, with the open battery compartment towards the reciever.

6. Turn on the power to the microphone and the red battery LED will illuminate.

7. Then press and hold the microphone on/off button (make sure green RF LED is still flashing).

8. When pairing is complete the green RF LED will stop flashing and will stay illuminated.

9. The green LED may go off due to the microphone being switched off. Turn microphone back on using the on/off switch. If the geen RF light is illuminated and remains on then the mic is paired.

10. Repeat these steps to pair Channel 2 microphone.

11. There is no need to repeat this everytime you use the system as the frequencies will be locked in and stored for the next use.

12. If in future you need to re-tune the microphone due to interference etc, please follow the above steps again for one or both microphones as required.

IMPORTANT NOTES

Do not set both microphones to the same frequency as this will cause interference and may damage your equipment. If the interference is occuring make sure that your channel selections are far enough apart from each other. See channel frequency list for help.

Trouble shooting

Problem

No output from microphone

Check

Check power to reciever is on and the red power led is illuminated, check batteries in handheld microphone

Check the microphone volume level is turned up sufficiently ( one for left and one for right hand microphone)

Check that the 6.35mm audio lead from the reciever to your mixer is connected correctly

The hand held microphone will not connect to the reciever

Check the microphone input on your mixer has the correct volume and level settings

Check batteries and fully charged (always use good quality branded batteries)

Check that the microphone is paired correctly to the reciever . the green RF light should illiminate. If not ,Follow steps for pairing and try again

Ensure that the microphone frequency is not set the same as the other microphone. Use the dipswitches on rear of the reciever to select a a different frequency
