| fuckin hiss.... |
 |
|
Yo.
Ive asked this before, but never got a proper answer..
some of my outputs on the sp got this kinda loud hiss. mostly output 7, but sometimes output 6. some days all the outputs works perfectly, no hiss at all and loud output volume even from the main out. that days i can turn the volume knob to the fullest without getting any noise at all! but that dont happend that often...
so, does anybody know if there is any way to get rid of this hiss? cuz sometimes the hiss gets so loud the beats looses all its bang.. guess i could start running the individual outputs and just cut the nr.7 and use the 7 other ones.. but it would be nice to have 8 working channels.
hope anybody can help me out!
peace,
s.raw

maybe one of your ssm chips is bad? In which case I would recomend sending the sp to forat.
Also try opening up your SP and reseating all the chips that are sitting in black plastic seats. The chips that sit in those black plastic seats (NOT the chips that are soddered directly to the motherboard) sometimes pop out of hte black plastic seats over time due to contraction of the sp heating up and cooling down.
make sure ure grounded and put ure finger over the chip in the black plastic seat and push down and u should feel and hear it getting reseated.
the chips that need to be reseated are not directly soddered to the board. the chips that need to be reseated sit (and i mean literally) in these black plastic things .
 the chips which i have put a red rhombus around are two examples of the chips which sit in black plastic seats.
When I had moved my sp around, i had to reseat my chips because I was not able to sample.

aight... but how do i replace this cap? :S
i got another problem with my sp... fader number two stops like 3 steps up in the volume and tune scale... it wont go down all steps! so when truncating samples it cant go to zero. it stops at 650.. so if you truncated a sound and want to trim the startpoint, and you're pulling the second fader upwards, it will pop to 650 and then you wont be able to get it back to zero. anoying.

Make sure you are grounded, then open your SP, look what brand and model no. your capacitor has (usually the bad ones get brown or black) and order it at an electronics store like www.digikey.com
Then you (or a guy you know that is good with soldering) unsolders the bad capacitor(s) and replace it with the new one(s).
The problem with the slider might also arise because of the capacitor problem, I would suggest that you run the Diagnostic test (there is a slider check) :
"To activate the diagnostic software, power the instrument up while holding down the SETUP button, or press SETUP before a disk is loaded. "
Good luck ! |

You're welcome.
But you know what grounded means ?
Make sure you touch some metal first (radiator for example) to unload the static electricity (that could harm your SP electronics).
Here's a pic of capacitors : http://industrial.panasonic.com/w...200512MC002_e/nr200512MC002_e.jpg |

the thing is that i live in sweden, and it will cost me mad money to ship it forth and back plus the charge from forat.. but to replace a capacitor cant be that hard for someone who works with electronics? so i guess i will ask someone who knows how to do it here in sweden

Yeah definately..if it's just the capacitor it shouldn't be that much of a problem. For someone good in electronics this is a piece of cake. That's what is nice too about those old samplers, the repairs can be done by yourself in most cases. |

Save your $ and get a gate. I just picked up a DBX 266XL comp/gate and the gate algorithms are really good. My hiss dissapeared. Obviously, when the gate opens, the hiss is present but if your release time is set right it really helps. Use it on affected channels.

that really aint a soultion to fixing the sp. its like puttin a bandaid on an infected injury... yeah you aint gotta look at it but you still aint doin good. nah mean. ive heard of people rockin a gate on the outputs for sp's in working order but if your joint is broken id reccomend fixin it.

Dude is in Sweden. Shipping it to Forat and back will cost him an arm and a leg. Not to mention the risk of sending it freight and crooked customs. The thing with the hiss is that its a clear indication of the voice dying. I remember speaking to EPR and they were clueless. "I don't understand, the SP usually has a great signal to noise ratio" is all they could tell me when I was out in the US. If anyone is in LA, or long distance calls permitting, maybe you could call Forat and find out what he thinks are the causes of hiss.
Yeah, I'd much prefer fixing it but throwing around wild guesses about capacitors and reseating chips doesn't inspire much confidence. A bandage is better than letting the wound fester. A gate goes for around $30 on ebay until a concrete diagnosis is reached.

i got the service manuals to either machine if you wanna bring it to someone experienced in fixing electronics. stuff breaks in europe too right? i know if something was fucked up wiht my machine theres a handful of people/places i could bring it to aside from forat, especially if its just a cap that needs replacing.

No, you're right. There's loads a places to bring it but these guys get paid by the hour so if you don't know what the exact cause of the problem is, electronics ignorance could end up costing you. Unfortunately, Emu don't have any authorised service centres still specialising in the older gear. Nor do they recommend officialy.
I'm hoping maybe someone puts their finger on the exact cause of the hiss as it seems to affect a few users. Its not so much that its affecting certain channels but its quite sporadic so maybe today OUTS 7 & 8 are hissy but tommorrow, it might be 4 & 6.
