Portable Voice Amplifier for Classroom Use

[dip.sarkar]

Hi,

I am a teacher by profession and recently advised not to over strain my voice due to some throat problems.

For this I am looking for some portable voice amplifier products that could be used in classrooms.

Can someone please help me in this regard? I badly need some guidance.

I'm looking for a Portable (preferably a belt version) Amplifier with good amplification and preferably powered by AA rechargeable batteries. My budget is around Rs. 3000/- (three thousand).

Please suggest a few brands that fit the above criteria and (may be, hopefully) are available in Kolkata!

Please help...
