FWIW, I was using an iMic before, but using it with the iBook leaves a
"computer hash" noise at about -45 dB. My G4 is quieter. The noise is
down at about -60 dB, which is just on the edge of acceptability for my
non-pro use. The Edirol seems much more quiet, but, that ain't worth
much if there's clipping at normal levels.
TIA,
Ed

The UA-1A is a -10dB level device. so if you feed it a (pro) +4dB level
input it will clip quite easily..

I don't entirely understand how one is supposed to use a device without
a volume control. The only thing I can recommend is that you do your
recording with software where the input-level control is *not* disabled.
For example, Amadeus, Sound Studio, or Montage. m.

I submitted a question to Edirol via their web site and received a
prompt reply. They confirmed that it's designed for a -10 dB input. They
stated unequivocally that the UA-1A input level "is not adjustable via
software or hardware control." Bummer. Their explanation for the
clipping was that my output is "hot." It's a tape output from an NAD
pre-amp, which I would expect to have a standard -10dB signal, but I
suppose anything's possible.
I put an equalizer in the line, which allowed me to clumsily reduce the
level, and the playback revealed clicks, which were revealed to be
discontinuities in the waveform. Fault of the Edirol or the iBook? Moot
point. I'm returning it.
This product may be useful if you have a mixer with variable output, but
if you expect to use this to record directly from your stereo, then
you're rolling the dice.

Sorry the other apps didn't work either. I use an Edirol UA-3 (
predecessor to the -3D) and it's been great. This has input/output
volume controls.
I had the same problem with clicking when I tried the iMic. But I've
never had any such problem with the UA-3. m.
I was thinking about getting a UA1A to run on my gf's laptop, but I've
heard that they don't function too well. I see that you're having
problems too.... Hmmm.
