Personal Voice Amplifier Instructions

  1. 1

    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.

  2. 2

    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.

  3. 3

    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.

  4. 4

    4When 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.

  5. 5

    5Always 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.

  6. 6

    6Avoid the microphone being too close to the voice amplifier speaker as this can trigger feedback interference (a squealing sound) from your speaker.


  1. 7

    Do not hold the microphone any closer than 2.5cm (1”) from your mouth.

  2. 8

    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.

  3. 9

    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.

  4. 10

    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.

  5. 11

    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).

Easy to carry, simple to wear…

Only a whisper is required for the voice amplifier to provide excellent amplification with the boom microphone. Alternatively the clip on lapel can be positioned on or near the lapel providing a more discreet option.

Supplied with a lightweight headband type boom microphone and optional lapel microphone. A necklace and belt clip attachment make the device easy to carry, and simple to wear and remove.

Also has a facility for use with a computer or mobile phone making it all the more versatile for the user.

Enhancing even the faintest of voices with minimal effort…

Designed to help young or elderly people with voice disorders or acquired communication difficulties, that have resulted from Parkinson’s, multiple system atrophy, motor neurone disease, multiple sclerosis, suffering a stroke, or other vocal damage resulting from surgery around the vocal chords or voice box.

For people with a week or strained voice, possibly caused by vocal damage, or for people who rely on projecting their voices for a long period of time and therefore using their voice intensively, this voice amplifier will maintain volume and clarity over that period of time without straining or causing further damage to the voice.

Can assist by enhancing even the faintest of voices with minimal effort required by the user, thus giving the user more confidence, and helping control the volume of his or her voice amongst a group of people.
