hey ppl wats poppin... i wanted a mastering solution so i purchased the ultramizer dsp
1424p. I use the mbox 2 mini interfae. i thought i could run the outs of my mbox to the
ultramizer, process the material and record it back into my DAW, Before maximizing the
audio records nicely but whenever i maximize the audio it is distorted. I thought the ins
were turned up too much but even at half way i got the same result. I'm wondering if if i
have too resort to buying a dedicated hard disk burner or is it that i'm just not doing
something properly... or would a change of interface help. thanks in advance for the help

1)Confirm what is coming out of the Ultramizer is clean to the ear, by plugging them into
an amp with a volume control
or into the back of a headphone amp. If it's clean
it's something to do with an overloaded input stage on the Mbox
or an A/D input
overload (i.e. digital overload)
2)Try switching the pad in (though what you
are doing should not increase signal levels that much)
3)Make sure the gains
are down
Make sure that your output meters are not going into the red
(hitting 0dBFS) on the Ultramizer. There may be a brickwall
limiting function to
stop this, but whatever happens make sensible judgements as to whether your processing is
improving the sound or not.(by monitoing through the Mbox headphones or via the
outputs)
It could be the inputs on the Mbox are expecting signals reffed
-10dBV and you are driving it with an output stage ref'd to +4dBu (about 11dB difference
roughly) and once you maximize you are putting out +20dBu or similar which the Mbox is
finding too hot.
cheers

i've tried all those suggestions in the process but to no avail. i know that the output
material is clean cuz i'm monitoring it thru my monitors while it's being recorded. tried
pading and it dosent work either. i guess it's only safe to assume that the inputs of the
mbox cant manage the processed signal of the ultramizer. with that being the case however
is there an interface that can take such signal levels? i really want to resot to a burner
as my last solution

The LINE inputs of the Mbox 2 can take +21dBu which is pretty high and higher than the
maximum output of the Ultramiser which is only +16dBu (According to Behringer's specs).
You are using the TRS jack sockets to connect the Ultraniser into the Mbox
aren't you? The XLR mic input sockets won't cope at all.

He seems to be using the Mini2, I could not find specs for that and I think it has only 1
mic input.
This should theoretically work, you need to be 100pct sure
of what is coming out of the Ultramizer is clean first(monitor via the outputs that are
going to the A/D of the M Box,
even if you have to remove them from the mbox, you
must 100pct be sure that this specififc signal is clean)
If it is it is
definitely your signal level into the Mbox nnalogue stage or your are clipping the digital
on the way in.
If not, I am stumped, good luck.
