I had no problem running a 2882 +DSP off Firewire bus power with my Quad G5. I hotplugged the box, no problem.

Got it all hooked up now clarity & depth of this unit is simply amazing, i've been using M Audio Firewire 410 for last 2 years (God Forbid), when i hooked 2882 the level of sound coming out was really loud which i found out was to do with my 410 running at -10db and 2882 console was set to +4db which i also found out is the Professional standard.

I can't keep my console settings on +4db as i have Mackie 1604 mixer and can't turn it up LOL if my master channel is a quarter of the way up my speakers (Genelecs 8040's) are are on the brink of blowing up.

So my question is, is it ok for me to keep all the mio console ins and outs at -10db will i lose gain from the noise floor dont really understand the reason behind the +4 & -10 maybe someone could explain?

To me it sounds how it was before level wise maybe it also has something to do with my new balanced cables as with the 410 it was unbalanced so i had to use unbalanced cables.

Is there a loss of benefit from running at -10db i dont know, would be nice if someone could enlighten me. Thanks for replys so far dont know what i'd do without advice from this forum.

Thanks in Advance, Karl........

Hi Karl, -10db is normally used in short cable lenght (like 5 to 10 feet) customer grade like a CD output (most rca connectors) for longer cable lenght one would use an XLR +4db cable 3 conductors as it will induce a lot less noise (noise phase cancellation). But if I has the choice between -10 and +4, I would go for +4 to wire everything. Unfortunately, a lot of equipement will output at -10. So you basically need both. Yes the Halo interface is fantastic sounding. Almost bought one last year. I am using a MOTU 828MK2 I will upgrade to Blacklion modification in a near future (clock replacement plus all op amps)
Hope it helps...
