Touchmaster PA Question

[crescentstar69]

My Touchmaster PA isn't working. Several different mics that are known to work have been tried with it, and the PA still won't work. I need the PA function for an off-duty detail I work. Does anyone know of any common problems, or tips/tricks etc. for this issue? I like the TM4 because the air horn will work without a master switch having to be turned on. Do any other "modern" sirens do this?


Ironically, I collect sirens, but they are all older and for display. If I can't get the Touchmaster PA up and running, I will be looking for a cheap unit with at least PA and air horn. In fact, if anyone has something, PM me. I don't care about siren tones or switching capabilities. Cheaper is better!


Thanks,


Mark

You may have a loose solder joint on the inside of the touchmaster. Look inside the area of the microphone input jack. You will probably find a loose wire or solder connection. Good Luck!

If the TM is no go, you can use a Unitrol 80K which is remarkably simple and flexible with mounting options. With the amp tucked out of the way, you can either use a free hanging or mounted PA mic jack and the air horn input is a simple 12vdc input for airhorn.
