I have a ProCaster that I haven't used in a while. I'm thinking of selling it, so I pulled it out and hooked it up. It's not a great installation, with a minimal ground, but without enabling the built-in audio processor, it sounds very good.
The problem is when I enable the audio processing. The sound gets a high pitched whine in the background, and it sounds hollow and seems to be coming from a great distance. The compression and modulation pots still work, and seem to do something, but overall the sound is very crappy.
I'm wondering if anyone who is familiar with these transmitters has any ideas. ChezRadio has a fixed price repair service (US$65 + US$35 or shipping) but I'm trying to avoid that if I can - in Canadian dollars add another 35-40% for the exchange rate.
I'm currently using software audio processing (SoundSolution with Zara 1.4.4) but the load (with streaming software) on the old laptop it's running on is causing problems. Besides, I suspect that the built-in processing on the transmitter will sound better than SoundSolution, particularly with the120%+ positive peaks it supports.
I should mention that this is one of the first ProCasters built - the tuning meter inside is marked Talking Sign (they used up the remainder of the Talking Sign parts in the first builds of the transmitter.
