Hi it's been quite a bit since my last visit.
I am having a problem with my BX5a. My DAC was sent to be fixed (used balanced XLR usually), and won't come back anytime soon.
Last night I tried to hook up the same RCA-TRS cable I used (before I switch to XLR) to the output of 1212m 0202 sound card, with a RCA female->TRS male adaptor.
One speaker gave a very loud bang and the blue LED went off. It sounded like the speaker is blown. Fact is one of the fuse in the speaker blown.
The other one worked well till a few hours ago. I connected the remaining BX5a to the TV with the RCA-TRS mentioned above. Fuse blown.
Then I went to buy some T2A fuse to replace those in the speakers. The blue LED came back on, both speakers. I don't have other devices that use XLR as output so I kept trying different unbalanced source and cables. Fuse blown, the story goes on.
I almost came to the conclusion that the BX5a is defective, or at least the TRS input part. But what do others think? How likely are the XLR input are still alive?
Capacitors inside looks good.
OPAMP are JRC 4580, are they the trouble maker?
the amps are TDA 2052 with mute function. possible that the amp came back from 'idle' after plugging in the cable, and something went wrong?
