Head Phone AMp / Mic

jleaman · 13th April 2006, 08:56 PM

At my work we use A Panasonic phones that does not have enough volume for our headphones / Mic's. I’m wondering if any one has a buffer / op-amp to suggest to me to use.. We need to be able to adjust the input volume ( Mic ) and output volume ( ear Phone )

It should be able to adjust the Mic and head phone level's. Is this possible I only need to make a few.

I'm thinking a simple op amp with 2 9V batteries and a simple pot for each Mic / head phone.

Any idea's guy's.

Yes I have researched commercial head phone amps for these phones and no one makes them.
