I have a Motorola microphone with the push to talk with a XLR 3 pin connector that I want to interface with my pa system that has a keyline for the push to talk and a separate audio input for the microphone. Any ideas? I hooked it up and played with it and just don't really know what I am doing. Any ideas what I got to do to make it work or do I need to purchase a special interface card.
Several others have hinted or asked that you provide some concrete information. One even asked nicely for a picture.
So....
Please post a pic of the mic and connector
***AND*** the Motorola part number or model number that should be on the case some where. Motorola makes or made hundreds of different microphones for mobiles, portables, and base stations. We can't begin to give you a useful answer without knowing which mic you have.
Please give us some useful information about the amplifier as requested. Make, model number, and power rating for starters would be helpful.
If you really want some help with this, you have to give us enough concrete information to figure out how to make your project work.
