Personal Voice Amplifier Instructions
Before use, you will need to charge the voice amplifier. To do this simply plug the charger into the top socket DC 9V (4) on the side of the voice amplifier unit for 3 to 5 hours.
When the voice amplifier is charging, you will see a flashing red light (1). When fully charged , the red light will stop flashing and remain constant until you disconnect the charger. Your voice amplifi er is now ready to use for up to 12 hours.
Before plugging in a microphone ensure the unit is switched off. To switch off simply roll the volume switch (7) to the left until it clicks shut. Select the microphone you wish to use – headset or clip on lapel, (or optional throat microphone – not included in this pack), and plug into mic socket (6) on the side of voice amplifier unit.
When using the voice amplifier, a blue light (2) will appear and when you plug in a microphone an orange light (3) will appear to tell you the microphone is connected and your voice amplifier is ready to use.
Always start with a low volume by rolling the volume switch (7) to the right a little, and then increase this action until you reach the required volume.
Avoid the microphone being too close to the voice amplifier speaker as this can trigger feedback interference (a squealing sound) from your speaker.
Do not hold the microphone any closer than 2.5cm (1”) from your mouth.
You have a choice of headset microphone or clip on microphone. Both have recently been upgraded for even better performance. The lapel microphone was omni-directional (picks up sound all around in the room) and is now uni-directional which means it is now directed towards your mouth and therefore more efficient.
The clip on microphone can be clipped onto your lapel, collar, or clothing. You can even clip the microphone onto your cuff (cable can be hidden by running it inside clothing) then simply raise your hand to the proximity of your mouth when you wish to speak.
The Aux socket (5) on the side of your voice amplifier is for use with your mobile phone or PC. Simply plug one end of the auxillary cable provided into the Aux socket (5) and the other end into your phone or PC speaker / audio-in socket.
If you also wish to use the unit for playing music, you can use the TF card socket (13) or USB flash drive (MP3) socket (8). You can then select MODE (10) (short press ‘M’ to switch U disc to TF card play, and long press MODE (10) for continuous play (loop) – additional functions for playing music are Play/Pause (10), Previous (9)
and Next (12)

Did you know?
This voice amplifier is designed with an inbuilt noise and feedback interference reduction function. Always avoid positioning your microphone near the speaker unit when switched on, as this can cause the unwanted feedback. Microphone squeal is caused by feedback. Feedback happens when your microphone picks up the output sound from the voice amplifier speaker, which it then re-amplifies causing a loop which is caused by the microphone picking up the original amplified sound and amplifying it again and again…until the sound can’t be amplified anymore and something has to give.
Usually your listener’s ears!
