Aloha,
I've had this Firestudio Project for a while now, and there's always been an incredibly annoying earth hum.
I've been able to live with it whilst recording heavier music, but when attempting to work on my jazz bass duet...it becomes agitating and downright unbearable.

I've tried searching other forums, googling the problem etc.
but there doesn't appear to be any straight answer!:hyper: (no smiley face)

All and any help would be appreciated!
Thanks in advance

The earth hum is likely caused by your setup BEFORE the interface, and not the interface itself. As such, you need to give us some info on what you have in your setup! is the hum apparent across all types of input (ie mics, DI'd bass, direct-into-line bass etc)? If so you need to look at what piece of gear or situation is constant with all those sources.

The preamps on a cheaper interface are likely to be a little noisy at high gain, as are the A/D converters, but it shouldn't be enough to worry about. Unless there are some blantently mad things going on like sitting the interface on top of a power transformer or something :)

well, my setup used to be an M-Audio MobilePre (pretty much, their equivalent of an M Box) into my KRK Rokit 8s and there was no unnecessary noise at all!
Naturally though, that is because there was no power going into it besides the USB.

I bought an american Firestudio Project, as it came with their faderport mixer and 5 XLR cables for free, which I figured was pretty sweet.
I live in Australia, so logically, I knew I would need to use a stepdown tranformer (from 220v to 115v) so that it actually works.
It can't be the preamp of the interface because i've bounced what i've recorded with it and there's no earth hum when it's played via my iPhone or computer speakers

my friend thinks that the stepdown transformer is somewhat responsible for the hum, which is probable, however, without it...I can't use the interface!
Though, I have seen some hum-destroyers on the internet, but naturally, don't even know where to start when i'm looking for one!
aaaaaaah
