SVS PB10-NSD - Fuses Burning Out Quickly ???

Hi!

I just recv'd my delivery of PB10-NSD. Yes it is gorgeous ...:D
massive and heavy ...:rolleyes:


Anyway, the trouble is that in less than an hour, the Sub has blown all 3 provided fuses....



It switches on for 5 minutes or so. music comes on and then all of sudden goes dead.

Bass gain is about 3-5 out of possible 8.


Connected using originally supplied power cable to Sub out on my Pioneer 1016 ......


Its getting me worried. Surprisingly, the fuses seem like literally "[email protected]" :(

And yes, I am using a home made cable using "Pro Power RG6U" coax to connect it.

So :lease: whats happening ???

Hate to say it but that is a fault. There is no way any electrical equipment should be popping fuses even when driven hard. I would consider the possibility that you need to send this back.

Completely agree. Its not normal for any sub to blow fuses regardless of what settings your using.

A blown fuse is there to protect you and the equipment when a fault or dangerous situation arises.

Get it sent back off to AVSales and demand a replacement in time for Christmas :D

I have blown a fuse on My PB12 Ultra before but not in normal use. I played a test tone whilst accidentally having the gain too high and after an almighty bang the fuse blew. New fuse and sensible settings and it ran fine again.

I am not sure about the PB10 but having set the levels of my sub the processer level is about -5bd and the gain about 9 oclock which is a lot lower than your settings.

I am not saying you have it set too high, it does seem more likely there is a fault, just that it is possible to blow afuse by overdriving the sub.

Yeah, I have send them a message already, and I shall be speaking to them fist thing tmrw morning. But still, I am not sure what really is the cause behind this.

I wasn't even hitting the sub...:(

What I did after unpacking it, was to put it in middle of my room. Read the manual to see if there was 'anything to be wary off'. Plugged AC and then RCA. Turned the gain down to MIN. and put music on. It wasn't even loud. And then Sub tripped to my surprise, only to be found out after 10 minute, that the fuse is blown.

And it kept on happening after random periods of time, though never longer than 30 minutes, I guess, until I finished my all 3 fuses...

My RCVR though is perfectly well. and the cable seems to be fine as well, as last time I switched on the SUB, it was without any RCA Input...:(

I fancied a bit musical Xmas.


But now i am Very Worried.

Any help :lease:

I wonder if you have the 240 volt version,maybe yours has a 110v transformer.Could be they have sent a U.S. model in error.

It'd blow straight way if that was the case, not after five minutes. It sounds like a component failing once it gets up to temperature to me, although don't ask me what. Either way it's definitely a return to dealer job. I think we're all agreed on that.

Or an amp swap. Whatever you do don't try any another fuse! Definitely a no-no.

These SVS distributor chaps have been known to work on Sundays as do the SVS big guys themselves. So you can probably expect some swift service.

I dunno about SVS in States, but my distro AVSales/Kent Home Cinema [UK-Wide Distro] is shut today, I have sent them a msg about this yesterday, and hopefully, I can get to speak to him first thing tmrw morning.

And yes, it says 240V on AMP itself, so I am sure its not burning [besides there are no smokes :)]

I had bought a couple of fuses today, but now I am thinking about leaving them aside...

The only troubling bit about RTB is to pack it back, and then ask someone to stay at home and wait for pickup, since I will be at work ...:(

Cheers for all the constructive input guys ..

hi bym007

I also have the PB10-ISD and I do have the Pioneer 1015 witch is similar version to the 1016. I recommend you to use the MACC option on your amp that will set the speaker and sub levels right. It even does an accoustic EQ for your speakers. unfortionatly not for the sub, at least not on the 1015. My amp sets the LFE at -1.5db and my sub's gain is turned at 10 o'clock (If I turned it to 9 o'clock my amp's microfone could hear the bass anymore).

I still wonder even if I can overdribe my PB10 with my 95 watts amp.

hi bym007

The power of the amplifier which feeds an active (internally amplified) subwoofer by low level connection (phono cable) is not relevant. The output voltage from LFE, Sub-out, Sub or Pre-out does not change with external AVR or amplifier power. It is a very low voltage to an agreed international standard.

An active subwoofer can overdrive itself if fed with a very high level input signal. This could be achieved by turning up the subwoofer's gain in the AVR's menu to maximum then playing films with very heavy and deep bass at very high levels. The driver will probably be damaged by the voicecoil hitting the endstops.

If a very powerful external amplifier drove a subwoofer by high level (speaker level) connections I suppose there might be some danger to the active subwoofer amplifier. But the input section of the subwoofer's own amplifier has a very high impedance. Which suggests the subwoofer would be safely protected from very high input voltages simply by turning the input gain control down.

In the case of this thread the fuse is probably blowing because of an unfortunate fault in the subwoofer's own amplifier.

In such cases one should not proceed to try more and more fuses. One should contact the dealer who sold the item. Or the manufacturer if no dealer is involved.

The item should be unplugged and the family warned not to use it.

One should never use a stronger fuse (with a higher amperage rating) than the manufacturer's own supplied fuse.

The fuse is there to protect the item and the user. If any other fuse is substituted for a weaker fuse (that keeps blowing) then a fire or electrocution is possible.

If a fuse keeps blowing then there is a fault. Which must be attended to and the item not used until the item is professionally repaired. Or replaced.

Opening an item without the permission of the dealer or manufacturer will probably void your guarantee. This simple rule will hopefully protect you or your family from electrocution.

I didnot understand most of your comments, as I am still disgesting the Audio stuff being a newbie. But being comfortable with electronics and computers generally, I did make it out as a fault in some electrical part of Sub, i.e. BASH AMP most likely.

Having said that, I did use MCACC setup on Rcvr to adjust channels, and distances etc. though Sub went thru all that conveniently, only to blow the first fuse when I put some music on it. The 2nd and 3rd fuse, though didnot take that long, blown in less than a second of being switched on. Which confirmed my doubts.

Furthermore, I have spoken to SVS Sales today, who have been kind enough to get my sub replaced with a new one in next 2 days ..... just in time for xmas holidays...:) Well hopefully, I will get over this trouble now.

Surprisingly, I remember only one fellow telling me about blowing his fuse, due to some [i cannt remember] reason on his much powerful 12-Plus/2 sub and that was only once. Even Ian himself at SVS Sales has been surprised by this trouble of consistently blowing fuses. According to him, he has never had this trouble ever before with any SVS sub.

Never mind, it will go down as another day, another experience...:)

And life goes on...

Cheers

My post wasn't really aimed at you. :)

More of a warning to the complete beginner who doesn't understand that electricity can cause fires and kill.

We don't want any more additions to the Darwin Awards website! :D

just another quick question bym007, is the MCACC on the 1016 able to do a room EQ also on the sub, or only the speakers. Because on the 1015 it only does the speakers.

I however still hope that very soon a very descent room EQ options will be available on a future amps. Denon also started making these room EQ functions. I just hate the idea of buying a BFD or spending a fortune on a SMS-01. I think that audio companies realise that about 50% of the audioquality is due to the speaker/sub performances. The other 50% is due to accoustics. And I expect this technology to be refined much much more in the future.

For me there is nothing more satisfying than pure tight, controled but still deep bass. :smashin:

I would not know about that. Because I haven't get a proper chance to play with my system so far. But if you help me access it or find it out for you, you may want to give me a bit of hint about typical menu descriptions for Room EQ, since afterall, I am still learning ....:D


However, if setting up Room EQ is something to do with channel levels, and/or speaker distance, then yes it is there...

Another update, I will be receiving my replacement sub tmrw. And guess what, I have ordered the SVS 5.0 speakers to go with it. Thought might give them a try... Will update you soon on this, once I am able to unpack them ...

Cheers....

Excellent news :thumbsup: that will make a superb package the SVS speakers really are rather good.:cool:

Let us know how you get on.

jeez

Yesterday I saw "the polar express" and the scene were the train passes by the boy's bedroom was just TOO bassy. For a minute there I thought my PB10 was going to blow a hole trough the floor and fall to the room downstairs. :rotfl:
This must be the most bass intense scene I've ever seen and onnestly it didn't felt very pleasing. the roomboom was to intens and I was wondering if it was my PB10 or just the ecoustic EQ that wasn't right. anyone happen to know how deep the bass in that scene went?

I am getting my stuff [svs 5.1 and pb10-nsd] delivered this afternoon, and since I am off work tomorrow, I will be putting the jigsaw together tonight. If you dont hear from me within 2 days, call up police/ambulance ... must have broken my walls ... :D
