Well I connected directly to the opam, and there was distortion, sound unclear. So what is the correct way of connect the speaker?
Thanks.

I see, the current is too low. My supply voltage is 32Vdc , which opamp I should use?
Thanks.
Hi,
I have an intercommunicator, that have an speaker/mic. I want to connect it in parallel and using an comutator, to a mic and speaker. For impedance fix I'm using an op-amp(lm324) in buffer configuration. I get notorious distortion, so I'm using a 6.8kohm connected to ground and out, that is...
No I just want to duplicate the signals to external mic and speaker.
Now the problem is that in the intercommunicator are 2 wires, black and white, both go to the mic/speaker. No other wires go from the circuitery to the mic/speaker. I thought white was +audio and black ground.
But exist...
Hi,
I have an industrial intercommunicator, that have a micro/speaker in one device. When the talk switch (see image) is closed it acts as phone when is open as speaker. I want to connect it to separated microphone and speaker, also use 2 new switch and new potentiometer? what device is best...
