[RBS] urgent: need advise about sound system

[Avraham Elkind]

Dear All,

I am desperately seeking to buy and install a new sound system for a certain
money changer whose name I won't mention here since such a mention will be
disallowed as an advertisement :-)

The former sound system failed miserably due to abundance of electrostatic
and presence of wireless equipment which I obviously cannot remove.

So, please send me any practical advise and suggestions as to what I can do
in order to boost voice in both directions with adjustable volume in both
directions, so that the client in front of the glass can be heard inside the
store, and the worker inside the store can be heard outside the glass where
the client stands.
Really, I am looking for a specific product recommendation that I can go out
to buy and to install.

Thanking you in advance,
Avraham Elkind
on behalf of Ari Enkin who is losing his voice.
We are both RBSA Resident(s)
