Value For Money :
Excellent
* I was looking for an A / D interface 2 channels minimum, running under linux and with good preamps
* The configuration is interesting to me: Guitar and vocals between Jack and then in effect processor and Rackarrack sooperlooper (looper).
* Use is: live performance guitar / vocals
* Computer Requirements:
I tested with two systems:
- Tour processor low-end AMD Athlon 2.7 GHz L2 Cache 1024 KB, 2GB of RAM running Ubuntu Studio rel Jaunty time kernel as an audio interface with Intel HDA alternative.
- Latest issue laptop Intel Core 2 Duo 1.3 GHz dual processor with 4 GB of memory and Ubuntu 10.04 lucid lynx noyeu 2.6.32-25 not rel time with native Intel HDA audio interface
UTILIZATION
* USB Audio drivers linux apparently stable
* I use the audio software on linux (jack, rackarrack, guitarix, ardor, rosegarden, hydrogen ...)
* Number of track record: 2, since the interface has only two entries.
* No need to update
* Latency: I measure when the computer was running rackarrack is very demanding in terms of audio processing as it turns conjuction up to 10 guitar effects. The acquisition frequence selected is 48 kHz.
- On tour with Athlon processor with jack + rackarrack: interface with systm = 8 ms (128 ech / PERIOD, PERIOD 3 per pad) with the same USB AudioBox
- On the laptop with intel dual core: works well. The minimum latency is 8 ms with 3 Periods per buffer and 128 samples per PERIOD. I can not go below this latency either the card integrates with the laptop (intel HDA).
I do not know exactly how typical to the computer is important because the processor does not ultimately turn a lot. On the Athlon, which is weak, it occupied up to 60%. I don't understand why I can not fall below 8 ms even if it's enough.
GETTING STARTED
No configuration necessary.
If you do not have any sound:
- Be careful to organize well the software associated with the Jack. For Rackarrack for example, you must verify that the number of period by buffer is the same as that of the jack otherwise no sound.
- There is a potentiomtre that fixes the mixing between the input / output in the listening
In fact the absence of sound can be attributed to the AudioBox, then it has nothing to do ...
OVERALL OPINION
* I use it for a month
* I have not tried other models (of this type) before.
* What I love most: the sound is very good
* What I like least: the low readability of potentiomtres
* Excellent price/quality
* Yes I would make this choice again
