I connected the audio line out (from my DVR) to the audio line in to my amplifier which has the speakers attached. When I attempt to use it for the two way audio, the audio from the camera microphone is always coming through the speaker when the amp is on whether I am wanting to speak or not from an offsite location. I can speak/hear from my android and it will transmit over the amplified speaker system at the location. (Using g DMSS lite) However, the channel the microphone is on…is continually broadcasting the audio over the outside speakers…not a good thing. My DVR is a Federal Mini 960h

What is preventing the audio from the camera microphone from shutting off to the amplified outside speaker when I am not accessing the talk/listen control?

Thanking you in advance for your help.

Good afternoon how are you enabling the microphone and speaker? Do you have a set up like in the video below?

Good morning Night Hawk you can use any type of speaker amplifier that supports the speakers usually a 8-16 ohms and 100 to 200 watts should suffice if the DVR/NVR has only 1 audio output you will be running the audio signal on mono.
