I live in a country with 230V mains and the two 315mA fuses in my XSP-1 Gen 2 blew again. It's the third time in 2 years. I like to play loud and my Emotiva amplifier has been plugged into the same outlet for the same amount of time. It never blew a fuse. Not once. I have spare 315mA fuses and can easily replace them but since I can read schematics and am handy with a soldering iron, I'd rather fix what is causing it to eat up more than current than the fuse can pass. What I want is to never have to replace those fuses ever again. Anyone here have an idea of what part needs to be replaced? Did you try using a step down transformer and putting the unit on 115v? No, I have not. Once I replace the blown fuses, I am sure it will work with a step down transformer. It may even permanently solve my problem of blowing fuses. However, this solution doesn't seem ideal for me since Emotiva sells the XSP-1 Gen 2 as a device that works on 230V. |

We also have 220/240 volts here in Australia and I recently, for the first time, had to replace the slow blow fuses. I wasn't playing "loud" and it was in HT Bypass at the time, so not doing any pre amplification. I suspected a power surge but slow blow fuses are different to normal (fast acting) fuses in their capability to withstand transient pulse currents. So they can withstand common surge currents, such as when powering on/off, whilst allowing the equipment to work as normal. Slow blow fuses do deteriorate over time and in case it re occurs, to save another trip to the electronics store, I bought a spare set and taped them inside the XSP-1 to make the replacement quick and easy. It's been a couple of months without an issue. It may be that the fuses your are using are sub standard and/or old stock. So my first suggestion would be to change brands/suppliers and see if that makes a difference. I'm not a fan of upgrading fuses (to ones of a higher rating) but it is something that you could ask Emotiva Technical Support. It is possible that you could use, say, 350mA without risking anything, but I'd make the call first. Cheers Gary |

The part number is 0285.315HXP. I was told this is a good fuse. Perhaps the fuses blew not because of a power surge but because of a voltage drop? My XSP-1 was ON when this happened, and it switched input voltage from 220V down to 110V as it should. But as the mains voltage went back up to 220, it did not switch to the 220V input in time, causing the power supply to draw too much current and blowing the fuses. If this is the case, I would like to remove the automatic input voltage switcher. Set my XSP-1 to permanently run on 220V. Would this be a good idea? |

Hi
Count me in in the list of 'display-on sound-off' XSP-1 owners.
I am in Greece, we have 220V voltage. No other system presented any damage. Mind that I use protection between the grid and the XSP-1 power cables.
I will check the fuses as everybody suggests. (the XSP-1 was bought last June)

I put a bit bigger ones (500mA). Now it is OK. I got my sound back. |

My XSP-1 has been running awesome for about a year or two max. Then the other night I went to turn it on from standby and it does this click like its clicking on the light come on for a split second then it clicks all the way off. I unplugged everything and change the power plug /wall outlet and it continued to do the same thing. I did notice the red blinking light in the back on next to the power plug adapter. I'm in California so it's 110v. I haven't popped the hood yet to take a look at fuses or anything but has anyone seen or heard of this issue before? Happy New Year All, I had powered down my XSP-1 Gen2 for Christmas vacation. When I returned yesterday and switched it on again after 5 days off, the standby amber light came on, but after the standby button was pressed, the blue lights flicked on, then instantly off back into standby mode. My unit was purchased in October 2014, and I have had intermittent problems with the lights coming on but no audio. I run at 230V, so all my replacement fuses are now 500mA slow-blow as previously agreed with Emotiva Support, when I had found that the 315 mA standard replacement fuses blew very quickly. Anyway with this different on/off problem, I disconnected the XSP-1 and tried a different power cable and socket . No joy. I then changed all the fuses in the unit with new 500mA, Still no joy. At this point I contacted Emotiva Support, and they advised that it would require repair. However, after I left the unit overnight to warm up in a heated room, then placed it in standby mode for 15 minutes, the unit powered up normally and was able to play audio. I normally leave it powered up 24x7, so I am guessing it was either temperature-related (only down to 2-3C/35-40F so not freezing!), or a slow capacitor-charging problem when initially powered on from standby. Either way, I am relieved that it works! I am not sure if this would apply to other XSP-1's, but thought I would post my findings here. Cheers, Grant |

I have a XSP-1 Gen 1 but I think its one of the later ones as has all black PCB's and uses v4 power supply board.
I had the same issue in Nov 18, display on but no sound and no trigger out working. It was traced to one of the 315mA fuses. Replaced it and all back up and running. With the display working most think the issue isn't power supply related.
Just had the same issue again 6 months later. Don't have anymore 315mA fuses and against installing a 500mA - in my mind thats just going to allow increased current through to other components and I'd much rather replace a fuse than components / board. Waiting on more 315mA fuses arriving.
One thing that I have noticed after going through this thread, is my R22 power resistor looks much darker than R21.

Hello to all owners of XSP-1!
I also had a problem with blown fuses in the 220 volt mains.
Now, after replacing the fuses with 500mA (slow blow), the XSP is working fine. I heard that the final solution to this problem is to turn off automatic voltage switching in the preamps and fix the DC voltage to 220 volts.
Has anyone already done this? Maybe there is a detailed description of how to do this?

As mentioned in my previous post, some 18 months ago, I bought a spare pair of fuses and taped them inside the XSP-1 so that there would be no down time if they blew again. Fortunately I haven’t had to use them yet, but they are there waiting. I’d much rather rather replace fuses and maintain the factory safety standards than fiddle with the circuitry and/or use much higher rated fuses.
Cheers
Gary

It happened again. After 2 years my XSP-1 is out-of-order again. The same problem. There is no output signal. I can switch it on. The lights are on but there is no sound. There is no signal on phones socket too. The same happend 2 years ago. After service it worked 2 years and fuses blew again. I replaced them and there is no signal.

I would contact Emotiva and stress your furstration that the fix apparently did not work. Hopefully they will do right by you. |
