Just got my UX2. Runs smoothly on my Centrino (Dothan) notebook. Only tried it with guitar so far, seems very easy to dial in some usable tones. Positive so far.

Lunch Money wrote:Awesome, VMan! Glad to hear an actual user review. A question-- since the UX2 has 2 outputs and a flexible software interface, can you record the dry AND effected signals simultaneously instead of a stereo guitar or microphones?
Greg - it depends what you mean by 'dry'. What you CAN do is place one of the 2 sets of sends before certain FX and record, say, a modelled-but-not-reverbed signal and a modelled-and-reverbed signal simultaneously, what you CANNOT do is record a 'vanilla' non-modelled guitar signal and a modelled signal simultaneously (ie that other set of sends will always come after the amp model) - hope that makes sense - if not just shout and I'll try it in english :lol:

I have had my UX-2 for a couple of days now - very happy.

timmyo, I understand perfickly. :D It's unfortunate, though-- the physical technology's clearly in place to allow recording of an amp simmed AND a Direct-Inject (ie. completely effect and model free, just the guitar signal) track at the same time; however, the Gearbox just doesn't allow for it yet. Hopefully with an upgrade.

Worse comes to worse, I guess you could always get a splitter with impedance-matching and go into the microphone channel or your soundcard and do it that way, but I find that's pretty silly when all it would take is Line6 to add/change some code to the Gearbox software.

Glad to hear there are other positive reviews so far.

I agree that additional recording of the dry signal would be a nice idea.
Also, adding an internal re-amping option would be no big deal at all, from a technical point of view (quite some soundcard allready allow for such manouevres).
But then, it's still a pretty good VFM factor as is.
Having fooled around with a POD XT (stock, no additional amp models) just recently, I defenitely found it to be the best thing when it comes to modeled amps, especially the high gain sounds seem to offer more punch than a lot of other contenders.
There are 3 kinds of people:
Those who can do maths and those who can't.

I too hope they'll offer it in a Gearbox update - I asked specifically on the Line6 forum but not had a response, and yes, there is a physical workaround if I really feel the need for the functionality.

I recorded some snippets of acoustic guitar last night - if anyone's interested they are here:
http://www.timodonnell.co.uk/music/acousticsamples1.mp3 - 1MB mp3
http://www.timodonnell.co.uk/music/acousticsamples1.wav - same in a 9MB wav

Used the default Acoustic Guitar patch (minus its reverb), a cheap Studio Projects B1 large diaphragm condenser in to the UX-2 mic input. Played on an Avalon L-25. No additional EQ, just set up a foot from the mic and played.

I'm not fleet-of-finger and have no experience recording acoustic but as an out-of-the box sound it seems ok to me.

OK, long post - but here goes:

Included here is the entire exchange between me and Line6 tech support when I am just trying to get technical specifications on the microphone pre-amps.

The short version: You cannot bypass the mic/pre-amp modelling in the toneport. So that means you have to use one of their 6 or 7 modelled mic/pre-amp combos. There is no 'clean/passthru' setting. I still can't believe this. As a result, they simply refuse to publish the self-noise & gain specifications for the mic pre-amps.

If you'd like to record mic signals and then post process them to your desires, it doesn't appear that the Toneport is the answer.

Read for yourself. Original list of questions is at the bottom, with responses piling up to the top:

+++++++++++++++++++++++++++++++++++++++++++++++++

The TONEPORT is not a true bypass. Please let us know if you have any other questions.

Customer (Scott Lake) 11/23/2005 05:35 PM
So does this mean that there is absolutely no way to bypass a mic modelling process in the software? If so, then I think I will have to pass on the Toneport. There really should be a way to bypass the modelling so that one can do this post-process if desired.

Please confirm.

Response (Kevin) 11/23/2005 02:24 PM
Scott,
We have been requesting those specs from Engineering. Even if we know that raw spec from the TONEPORT, this would have little to no effect on the sound because of the modeling process. The head guy confirmed this. Please let us know if you have any other questions.

Kevin,

So there is no analog circuit to boost the input of the mic's? I understand that there are simulated mic processing features, but there has to be a stage in the device that is the amplification of the weak mic input signal, to a level that is used for the Analog to Digital conversion process. This would be the pre-amp stage.

Please, if it is possible, forward this on to a supervisor or some other person that can address the analog input section of the device. I do not want to know about the codec - that's shorthand for compression/decompression, in the digital domain. I want to know about the analog input section - like what is listed in every other device's technical information that competes with this product.

There has to be an analog input section to your device - it would not operate without it. This is the pre-amp stage. Sorry to sound preachy, but I'm getting a little frustrated with the lack of answers to my question.

Here are some examples of what I'm looking for:

This is for the PreSonus Firebox:
FIREBOX HARDWARE SPECIFICATIONS
Preamp Bandwidth 10Hz to 50kHz
Preamp Input Impedance 1.3k Ohms
Instrument Input Impedance 1M Ohms
Preamp THD <0.005%
Preamp EIN -125dB
Preamp Gain 45dB (+12dB digital boost switch)
+++++++++++++++++++++++++++++++++


This is for the M-Audio Fastrack Pro:
Mic Inputs (A/D)
Input Impedance 2.7k Ohms unbalanced, 5.4k Ohms balanced
Maximum Input Level from +24dBu @ min gain, pad on to -40dBu @ max gain, no pad
Channel-to-Channel Crosstalk < -110dB
SNR -101dB, A-weighted
Dynamic Range 101dB, A-weighted
THD+N 0.005% (-86dB) @ -1dBFS, 1kHz
Frequency Response 20Hz to 20kHz, +/- 0.1dB
Pre-amp Gain >40dB
Pad -20dB pad

+++++++++++++++++++++++++

Neither of these devices are 'pass-through' devices as you refer to the UX2 either, but they know what their microphone pre-amplifier specifications are.

I am starting to wonder if you understand what I'm trying to ask for - it's really quite simple - the same kind of data as what I've shown you for competitor products to yours.

I would suggest passing this question along to someone else, including the history of the question. I've saved a copy off for future reference for whomever can answer the question.

Response (Kevin) 11/17/2005 04:02 PM
The pre-amps are modeled preamps not physical preamps. The studio grade mic pre-amps are modeled. There is an audio codec which takes care of the modeling process. This is not a true bypass device. The information on the website regarding the TONEPORT's mic pre's should give you some insight but will not give you exact settings for the pre's. Please let us know if you have any other questions.
Line 6

Customer (Scott Lake) 11/16/2005 06:32 PM
So there are no actual microphone pre-amps on-board the UX2? What does the literature say when it says it includes studio grade mic pre-amps? Surely there must be an analog circuit before the digital stuff where the modelling is taking place, yes?

Isn't there a way to record direct from the mic pre-amps with microphones, so that there is no circuit modelling in place? What are the specs for that completely clean setting?

-Scott

Response (Kevin) 11/16/2005 04:46 PM
Live functions as either Rewire master or slave. There is no "pre-amp circuit" as such. The raw specs for the audio codec (AKM Semiconductors AK4528) would be the closest thing. The modeling process, however, means that the s/n ratio, dynamic range, etc. change as you change models to reflect the properties of the device that was modeled. As such, there's not any single set of specs that we can point at. Please let us know if this helps.

Customer (Scott Lake) 11/16/2005 08:55 AM
My specific questions about Live Lite that comes with Line6 is whether it will Re-wire as a slave to a different host like Tracktion; which can act as a Re-wire master.

I have read some on-line forum reviews of UX2 which have been quite favorable. I'd like to know a little more about the noise reduction feature of Gearbox, as this might make up for slightly noisy pre-amps if they happen to be that way.

Perhaps Line6 buys the pre-amp circuit from another vendor like focusrite or presonus?

Thanks for your time,

Scott Lake

Response (Kevin) 11/16/2005 08:45 AM
We are working on those specs. We understand that this does not resolve your question, but it does let you know we are working on the issue. As far as Abelton live goes, what are your specific questions? Please let us know so we can assist you. Thank you.
Line 6

Customer (Scott Lake) 11/15/2005 04:40 AM
My question is still not resolved on the specs for the mic preamps. And the questions for the Ableton software is also unresolved - since Ableton's website does not have any information there about the special Line6 version of the software.

So in reality, none of these questions have been resolved.

Surely there must be some specifications for the microphone pre-amps that were put in place so that the manufacturer of the pre-amps has something to design to and test for.

All I am asking for is to see those specifications so I can compare them against some competitor products in the same price range.

-Scott Lake

Response (Kevin) 11/10/2005 11:41 AM
We are working on getting these specs up. As far as the Abelton software goes, please contact ableton. Thank you for your patience. If you have any other questions, please let us know.

Customer (Scott Lake) 11/04/2005 04:36 AM
I realize that you may not have this information up on the website, but surely the microphone pre-amp specifications exist for the product - couldn't these be sent to me?

I'm currently considering the Toneport UX2, but also the M-Audio Fast Track Pro, the Alesis IO|2, PreSonus Firebox and the Edirol UA-25.

The mic pre-amps specs are fairly important to me.

I also want to have some kind of an idea what the Ableton Live Lite software is like.

Thanks,

Scott Lake

Response (Kevin) 11/02/2005 10:16 AM
Unfortunately, we don't have that information at this time. We are working on a list of mic pre specs. Please stay tuned to the website with the links that were provided. Thank you for your interest in Line 6 TONEPORT. Let us know if you have any other inquiries.

Kevin,

I did read through the website, watch the tutorials, etc. And I wrote my questions after doing that.

So, the questions still remain - except I think that the answer to #2 is yes. Other than that, I couldn't find the answers.

So, if you can point to specific pages where I can get these answers I'd appreciate it. I'm particularly interested in finding out about the noise specifications on the microphone pre-amps. I could find no mention of that anywhere on the site.

I haven't yet purchased this but I am very interested.

A couple of questions to answer that will help me make the decision to buy:

1. Can you give technical details about the mic pre-amps, particularly with S/N ratio, THD, gain, etc.?
2. Can one simultaneously record the line ins as well as the microphone ins at the same time via ASIO?
3. Does the UX2 come with Gearbox or not?
4. How does the 96 kHz record mode work - does it require USB 2.0?

Thanks for your time. On paper and on the website, it looks like a great product.

Best Regards,

Scott Lake

Thanks for that, Scott.

So hm, there's no analog amplification? All leveling is done *after* the (weak, as you stated) mic signal has been converted allready?
That'd be incredibly lame and the best way to lose audio bandwidth.

Of course it'd somewhat explain how they can make it that cheap.

I just orderd mine a few days ago. This was an option that I have not thought about, not being able to get the "dry" version of the microphone.

When I get mine I could do some test's on it, and se if I can compare it with my audiophile 24/96 and Behringer mixer.

Just tell me how to do the tests, because I have no clue.

These support people are stupid.

Sascha, there's no way that there's no pre-amp stage. There really HAS to be. It's just that these numpties either don't understand the question or don't have access to that information.

I'm sure Gearbox gives a "Mic & line 1" option. I wonder if the line inputs offer a true bypass that the support people are unaware of... hrm....

Greg, the nearest I can find about the gearbox settings for the pre-amps is the 'console' setting, which supposedly mimics a solid-state channel strip.
http://www.line6.com/toneport/vocals.html

The whole point I was trying to get the guy to answer in the e-mails was what the mic pre specs were. He insists there is no way to measure it or publish it because you have to choose one of these modelled input stages. Look in the thread, it says that Line6's 'top guy' says so. Oooh.

Actually, I think that it might be right - I can't see anywhere where they will bypass this modelling stage, on either the 1/4" inputs or the Mic inputs.

Too dodgy for me. Firebox has now gone to the top of my list.

Yeah.

I'm still getting the UX2 because I already have my Audiophile 24/96. I don't usually need a portable solution, and when I do the UX2 will suffice.

By using the SPDIF into the Audiophile, I gain another 2 inputs (making my Audiophile a 4-input device!), leaving me 1 analog input for my TubeMP and 1 for any other "line-level" signal such as a keyboard or other modeler.

Have to admit, it makes me leery of Line6's customer support, though. Those guys clearly demonstrated not only that they don't have a clue about the product itself, but that they don't have a clue about this category of technology in general.

Since I'm always recording either Guitars or Vox (I use virtual instruments for everything else), the UX2 still offers an attractive solution for the price. If the "modeled" pre-amp stages are any good, I won't have much to worry about at any rate.

Worst case scenario, I keep using the Audiophile the same way I always have, use the UX2 for 'emergency' mobile solutions on the laptop, and then use the UX2 as an 'effects box' rather than as an audio interface.

I think I am going to stick to the idea of getting the Presonus Inspire 1394 as soon as I raise the $200. I know it doesnt have any modeling, but it has 4 in's at 24/96 for the same price as the UX2.

Post

Just so you guys know, I have recorded the output of my guitar synth into this with no problem, clean. You have to setup the preamp section, but it really is not as big a deal as it seems to get a "true bypass". In actuality, the preamp you buy, whether it be the Presonus, etc., will have it's characteristics as well. So, I guess it depends on how "clean" you want it to be, and that is easily adjustable. Every preamp box you buy will have certain characteristics. The fact that there is no true bypass is a non-issue to me, it just needs to be set up correctly.

Cheers, VMan88.

Looks like the Line6 guy really IS an idiot. From the TonePort forum, supporting what VMan just said, too:
h1pst3r wrote:There is both a full bypass mode which is DI -- no amp, no fx as well as "no amp/no cab" which still passes through the fx.

h1pst3r
So, good news for people who may later decide they want to use, for example, Amplitube's modeling on a DI'd guitar signal.
