Amp Protection

trekker · « **on:** 1 Sep 2005, 02:45 pm »

I was wondering what type of protection do NuForce amps have? I have searched the website and I couldn't find a single bit of information regarding protection. What happens if the output is shorted, blown fuse, tripped breaker, current limiting, amp will go into oscillation? I know the amps run very cool, but is there any type of thermal protection just in case or will the amp blow a fuse, ...?

I know amp protection isn't all that glamorous to speak of, but amp outputs do get shorted for some odd reason or another and equipment do overheat due to unique situations.

Thanks,

Arnold

Good question. I'm going to test for any changes in sound quality when plugging a Ref 9 into a BPT unit. Hopefully Jason can report on any inherent protection.

BTW, I LOVE the McDowell mountain bike trails in your area. The old Cactus Cup race track is one of my all time favorites. I visit it every year, and it's still not often enough!

I just moved to the Az earlier this year and haven't had a chance to give the trails a try. I'm only about 5-10 mins from the McDowell Regional Park. When I was in Ca, I used every inch of suspension travel on my FS MTB.

The NuForce amps really have my interest, as my current 7 ch amp runs fairly warm, and I can hear the fans from 23' away

I do have to say that my amps current location, the ambient temp is 87-90 degrees when all the equipment is off. Some Air Cond contractors have said they can run AC ducts to my equipment if I wanted.

Atleast with the SMPS, the line voltage doesn't make that much of a difference. This is especially important since I have 2 AC units and a pool pump to really drop my line voltage. Curious to see if the BPT makes a difference.

I am really curious about the amps' protection.

Wow! You'd have a hard time raising the temperature even one degree with the Reference amps. Don't expect to huddle around them during winter time (although, that won't be an issue given your new locale).

I'll ping Jason to get an answer on the protection.

The amps have short circuit protection and it will shut down. It also has over current protection to shut down.
The caution you need to take is the no-load power on. In some instantanes, it will overheat and the choke will burn out. If that accident happens, we'll charge a very small fee for repair.

Thanks for the info!

I blew out one of my 8b amps. Let me just say that that is not a finacial problem with Nuforce. The main problem might be the time between when you send(I drove) the amps and when you get them back( I haven't a clue-since I drove-2 hours, maybe.).

I think it was few months ago when we haven't add the caution note in the instruction sheet about not turning the amp on without load.
Since it is not mmakshak fault, we replaced it for free.
