• Send telephone call audio over-the-air!
• Stereo line/microphone/phone line mixer!
• Automatic gain, automatic noise gating, variable compression!

Ever wish you could broadcast on-the-air telephone calls like the big guys do? Due to popular demand, and probably the most requested kit idea ever received, we came up with the PPM3 Phone Patch Mixer! This is a perfect match to any of our AM or FM broadcasters! Sure it’s easy to plug a music source into any of them, but when you want to add a microphone (after all, you ARE the Disc Jockey of your station!) and then want to put incoming phone calls on-the-air and properly mix them together it becomes difficult! Not anymore with the PPM3.

Simply plug your microphone, phone line, phone, and stereo line level program source into the PPM3. Connect the output to your AM or FM broadcaster’s line level input and you’re all set! You now have the ability to mix both sides of a phone conversation and control your microphone to equal volumes! Separate independent automatic noise gating and automatic variable gain and compression circuits are used for both the telephone line audio and microphone inputs to assure a great sounding output! The stereo line level mixer features mono injection of phone line and microphone audio for equal balance. Powered by 9-15VDC. Now when those people call complaining about YOU, put THEM on-the-air!
