I bought my Pioneer DDJ-SB a couple of years ago & while I like what it does, I've never been very impressed with how it sounds - somewhat brash & top-heavy. After buying it, I found that I was very much wishing that it had some sort of metering, and much more importantly, gain trim pots. So I'm sure you can imagine my dismay when the DDJ-SB2 was released just weeks after my investment, and at a lower price than what I paid too.
About 6 months ago, I became aware of a high-pitched whining noise on the master channel. You can't really make it out when music is pumping through it, but it is always there. If there are any quiet sections or gaps in the music, or if I use the mic channel solo, it's very obvious indeed.
The noise is constant, and does not vary when you turn the master output knob up or down. It isn't a ground loop problem; it occurs when I'm running my laptop off the battery, and even when just connected to a USB hub or power bank. Essentially, whenever the controller is powered up, it sends the noise out of the master outputs constantly. I suspect this constant noise is what I've been perceiving as poor sound quality for all this time.
Now there is every chance that the controller was like this out of the box & I simply didn't realise. I can't use it at home through speakers at any volume, so home practice has to happen in headphones, and the noise is nowhere to be heard on the headphone channel (cue nor master). That aside I've mostly used this controller for a couple of bar gigs where the speakers are small & quiet. Until recently that is, where I played a wedding & the venue's mixer was in a bad way, so I reached for my controller as a back-up, and on a big system it just sounded terrible. "Uptown Funk" has a very quiet intro & the noise was cutting through horribly. I can't use this controller as a back-up any more.
I've no idea how long the warranty is on these things, but I suspect it's no longer covered now that it's a couple of years old. When the SB2 came out, it was always my intention to sell the SB & replace it with an SB2, but now I'm aware of this issue, I don't see that it really has any resell value at all - a real shame when I took such good care of it. I spent a fair old whack on a quality Magma backpack for it too.
I like the portability & functionality of the SB and SB2. But I don't want to invest again & encounter similar problems. Having done some Google investigations, it seems that I'm not along in experiencing this problem. So can someone put my mind at rest & tell me that this noise isn't typical of the DDJ-SB/SB2?
Also, what is the UK warranty on these, and is it a manufacturer or retailer deal?
If this is a known problem (or regularly occurring fault) is the repair economical or worthwhile?
