Sad day, was watching TV, walked out the room to get a drink, came back, sniff sniff, uh oh... that distinct smell of dead electronics.... Wait why is there no bass on the TV anymore?.......oh.......
Sony receiver into iN3kDSP bridged into 4ohms on an SI DS4 (voice coils in series) that's in a 4cuft sealed enclosure. Been running fine for the last year or two and has suddenly given up the ghost, wasn't even running remotely hard at all (TV game show so it was mostly idle). When I looked at it, both knobs were red, stupidly I turned it off and turned it back on again in case it had randomly overheated or something. It has never overheated before and it's completely unmodified/completely stock but the IT person in me naturally went for the "turn it off and on again". Well it turns back on, there's a massive thump from the DS4, the left (channel A) knob is flashing amber/red, the fan spins up higher than normal and I can smell the smell again. I quickly turn it off with a massive thump again from the DS4 (this is not normal) and unplug everything. I'm hoping that the only good thing about the thump from the DS4 is that it hasn't been trashed along with the amp, my thinking being that if the cone can still move like that, the voice coils haven't dead shorted....
With all cables unplugged, I reconnect power ONLY and turn it on. Left knob is flashing amber/red but this time quickly reverts to just red and the fan shuts off completely which is not normal at all. It's dead Jim
Quick Google and it's a common issue, what's not common knowledge is the whole "register your product within 90 days to ACTUALLY GET the full 3 year warranty".... thanks Behringer, lesson learned. I do see a fuse on the board but I haven't seen if any has had any success in replacing it, I guess I can get the multimeter out and check for continuity? I don't see anything obviously scorhed on the board but it's late so didn't look too hard. Speaking of multimeters, should I check the voice coils on the DS4 as well? I'm assuming if they HAD actually fried, they'd show 0ohms or something?
So what are my next options? I was thinking about getting a Crown XLS 2502 since they seem
to get good reviews and are reported very quiet all the time, along with being able to completely shut off the LEDs (thank you!) it'll also allow me to drive the four SI HT-18D2v1s I have just laying around if I want since it puts out 1200W/2ch/2ohm and as I understand it, the HT18v1D2's are good for about 500-600W each? Not sure if the 2502 has been measured though. These would also be in 4x4cuft sealed enclosures, do I still need a MiniDSP on the Crown for this configuration? Do I run the DVC in parallel (1ohm) and then series the two subs (2ohm), or do I series the DVC (4ohm) and parallel the two subs (back to 2ohm)?
I see some concerning threads about the Crowns not actually putting out the power they claim but nothing about them ever dying. Has their power output ever actually been measured?
