FAQ’s

Will this function in other nations?

Yes, if you have the appropriate plug adaptor for the country.

Does this fit in a teaching setting? i.e., is the sound coming through really clear and crisp?

Yes, it is appropriate for a classroom. The sound is clear and somewhat echoed.

Can I connect an MP3 player, a microphone, and sing along to the music?

You will absolutely adore this!  I preach on the streets with it.  You can sing and play music simultaneously.

How can I recharge it while driving?

With the aid of a 3-pin converter (such as the 7509), the 12 volts of a car battery can be reduced to 9 volts, which can then be used to charge this voice booster.

Do you have volume control?

Absolutely, the volume control is easily accessible and conveniently positioned.  As we are on the bus, inside, outside, in crowds, etc., the level needs to be adjusted frequently when I am touring groups and using my Voice Booster.

Does this device have a condenser or a dynamic microphone? I’ve tried using an audio Technica pro 8 hex dynamic mic headset to play it, but it doesn’t work.

A condenser microphone is included. Dynamic microphone

Is this allowed to go to Europe?
If the wall outlets are different, you will need a converter for the included charger.

What is this item’s wattage?

According to the listing’s specifications, 25 watts.

Will it be effective to address a group of 60 individuals outside, as in a team-building exercise?

Yes, that will be really effective for that many people. I’ve been organizing a charity run in Utah for the past two years, and I’ve used it as a platform to address all the participants before, during, and after the race. Each time, it was 80 or more, and everything went smoothly. The amplifier has always been my favorite.

What speaker’s amp rating is this?

Select something else if you want it for music.  The best way to think of this is as a hand-free megaphone.

Greetings. My order arrived last week. How do I obtain the headphones, please?

The headset and microphone need to have been included. It does not come with a headphone to simply listen to stuff through the Aker if that is what you mean.
