from 1 Microphone to multiple (Please Help me )

[myacirkhan]

I required a circuit that have one microphone input to multiple output...
Actually I have 4 Loudspeakers Machine and i want to control or input from one mic..
The Current Setting is:
There is One mic which is controlling one Loudspeaker machine and from 1st machine's outputs are inputs to other remaining three machine, therefore i have to start the 1st machine as master. So is there any possibility to divide the 1 input to multiple.
OR
I have an idea that i can use four Microphone Pre-Amplifiers and input them with a single Mic in put

Pls Help me i am fed up of this..

Hi myacirkhan,
I think you can use only one mic preamp becaus hes output is normally loadable for ex. with 10Kohm.
An Amps Input impedance is for. ex. 50Kohm, you can put such amp 4x parallel on one output as source...
question; how is input impedance of your amp?
It will maybe little big worser on high frequency signal quality, but maybe its not the end of world for your application?

Bieng enthusiastic in the field, you shouldn't be fed up so fast with such a silly problem. Ok..you may do this...Use the same single mic, connect it to a pre-amp ( Naturally a Mic pre-amp) and then take the output and connect it in parellel to all the inputs of the other 3 speakers which have Aux pre amp as input then connected to a power amp. Thus you may switch only the required speakers which ever you need. I have persanally used this set up for more than 300 meters of audio communication. But remember to use a high quality Co-axial wire for connecting. Cheers
