I have a T-Amp connected to my HACS AB8SS to provide whole-house TTS announcements. It's been working great for about 8 months.
About a week ago, my speakers started making an intermittent crackle, maybe once every 20 minutes for a split second.
I thought it was either my USB sound deviec or my AB8SS doing something weird.
This morning about 20 minutes after I woke up, the speakers began producing continious static. I tried switching the speakers and the static moved from speaker-to-speaker, which made me think it was NOT the AB8SS. I then powered-down my HA PC, thinking it might be the USB sound device, and the static persosted. I finally realized my T-Amp must've gone bad.
Fortuneately, I had another still, still new-in-box, that I was saving for another application. I swapped it out with the bad one and all was well again.
I wonder what caused it to go bad.
- Is it just not designed for continious use?
- Was my Parts Express 12V 2A Power Supply giving it some nasty power?
- Is the T-Amp not robust enough to handle the varying impedence introduced by the AB8SS (The AB8SS does some impedence matching, and keeps the impedence between 4.92 and 8.49 ohms... actually in the 4's for 2-8 speakers and 8.49 for one speaker)?
- Maybe I just got a bad unit.
I'll have to check with Sonic Impact and see what kind of warranty these things have.
Anyone else have one go bad?
