USB bus powered interface with 6 or 8 ANALOG outs

Here's a question for you guys: is there such a thing as a portable interface that can provide 6, or preferably 8, independently assignable ANALOG outs (1/4" would be best), while being bus-powered over USB?

    Unfortunately from what I understand it does not work bus-powered over USB, only over Firewire.....

    Since I'm using it as a firewire device, I don't know if that's true or not but it is a great interface!

    One of many on-line stores.
     
    http://www.rme-audio.de/en_index.php
     
    The Fireface UCX operates in three different modes: driver-based USB 2, stand-alone mode, and
    Class Compliant mode. (so does the UFX).
     
    You will have to read about any of it.
     
    Of course there are others probably out there also.
    http://www.rme-audio.de/en_products_adi_8_ds_mk3.php
    You will have to talk to someone who knows more about them.
     
     I just have the Babyface which is Class Compliant now also, but not Dur-ec whatever record option like the UFX, in which I think you can stick in a memory card (like a camera ?) and record with the unit probably in Stand-Alone Mode all by its self. Have to ask one of the people here that own one or at a dealer about any of that.
     
    Okay found it:
    DURec: Direct USB Recording: The UFX provides a spectacular feature: an integrated digital recorder for all inputs and outputs directly to USB memory devices - USB thumb drives or hard drives with up to 2 TB capacity - via the front USB port. Independent from a connected PC or Mac.

    Guys, I need one that's BUS-POWERED, meaning it can be powered from a USB port without needing a separate power supply!!!!!! RME is awesome but......

    I personally don't recommend buss power if you can avoid it. 
    I have read a lot of threads here where people have issues like hum and not enugh power for phantom mikes etc. I have a friend who bought a Scarlett 2i2 who had a heck of a time with his laptop and hum. Then one of his LDC mikes will not work at all with it. 
    And if your needing multi channel recording / playback that will narrow the choices down to a couple of interfaces? That's not really a way to purchase something as important as a interface.  Like how inconvenient is it to plug in? Are you busking? 
    After all , any multi channel recording will be done where there is power available so why bus power? USB was not designed to supply power so it is a compromise only for convenience and is well known to cause issues on some systems.

    USB was not designed to supply power? Are you serious?
     
    All these recommendations are pretty funny I must say! First of all, "Johnny V", I have plenty of other stuff (MOTU 2408MK3, Motu 1224, Plenty of rack-mounted preamps, VS100 etc etc) so all your statements are not just beside the point, they're completely irrelevant. Who said anything about phantom power?
     
    The point is I'm NOT going to be recording with this, it's for doing gigs, running tracks! I need to be able to send stereo tracks to the house, click and mono track to the drummer, and hopefully separate BU vox to the house as well.

    According to Thomann, there is only one USB bus powered interface with 6 analog outputs: Fast Track C-600.
    Unfortunately,  only 4 outputs are available in USB bus powered mode.
     
    So, it looks like that such interface is not yet invented...

    Finally a response from someone who read the question!
     
    I was afraid of that answer! Hoping someone will step up to the plate and make such a beast.

    Good luck finding something. My RME Babyface has 12 out, but 8 are ADAT and it runs only on USB. So I doubt if you find one that has 6-8 analog out (not ADAT) without connecting to some kind of walwart power supply.
    But then since the UCX is 9-18 Volts (which is DC) (12 watts) center pin probably can run off of a 12V battery, but then I am not using any that way, so that is all I can say, I do not intend to run one that way. And I would not recommend anyone run one that way without checking it all out first.
     
    But I guess you have your choice of one, so is posted it seems to be that way.
    USB only puts out 500 milliamps so that includes anything else ran off of the same port (USB Hub) also.
    Not much power to run anything, and then there is the bandwidth that the USB port can handle also.
    Not any camera I know of that can download into a computer probably don't have a power supply also that needs to be plugged in (like a line power cord), although they will run off of a battery you can buy for the camera for power also I suppose which does happen for a limited amount of time. (I use my old cam-corder that way, but the battery needs to be recharged by a AC power line cord plugged into power after running down.) (and they include a USB connection but I doubt the cam-corder runs only on that - I do not know).
    ??
    If a RME unit could run off of a battery (like a camcorder) then I do not know what could be bought. You would have to ask RME about that.
    http://www.rme-audio.de/forum/
     
    Telescopes run off of a battery (usually a car battery or motocycle 12V battery) or AC line power.
     
     This post sort of makes sense to me, whether it does to you - well the post was edited.
     
    The UCX would take 12 watts of power to run it. It is not going to run off of a USB port, but maybe a battery, but then I do not know what kind of battery it could use if any, also like the UFX. (and I doubt if anyone uses any audio/interface that way. Again I do not know).
    Otherwise I guess anyone does not make it, except for that one mentioned in the previous post, but I be leery about that one claiming that.

    Car cable or battery cable for power supply for RME.
    http://www.rme-audio.de/en_products_cables.php
     
    run off of a 12V battery, the other listed is  a walwart cable power supply connection and AC power line cable.

    I know exactly what you were asking about. 
    You don't have to come back at me like that? what up with that? 
     
    I'm just trying to point out why what your looking for will be so hard to find. 
    There's a limit to what can be powered with usb 2.0. So I'm not kidding at all. 
     
    USB 3.0 has more power available. But go ahead and find a USB 3.0 interface.

    I missed the USB-powered part of your initial post because quite honestly it didn't register when I read it, as nobody's gear works that way.  
     
    I apologized earlier for my missing that, fair enough.

    As you're wanting to use it to feed tracks to a PA, why don't you just get a mains power feed from the PA guy/girl to power a normal interface?
     
    Or is the PA working from USB bus power as well?
     
    You want to send a click track to your drummer, so presumably there are instrument amps on stage for the drummer to hide behind.  Are these USB powered as well?
     
     
    I'm a FOH sound engineer, it's part of the job to supply power.  You'd be better off spending your time looking for a mains extension lead rather than a USB powered interface which would run down the battery in your laptop so you'd need power for that anyway....

    No there is no unit that I know of, which does not mean it may not exist.
    To power a unit such as a RME UCX which is a portable unit (or can be used as one) you need a power supply, the rest can be handled for the audio channels over USB (to say a computer or something).
     

    Car Cable

    (AUTOK)

    for MADIface XT, Fireface UCX, Fireface UC, QuadMic, Babyface, ADI-2, ADI-4DD. Power supply (used for telescopes like a car battery).

    but I do not know if it supplies enough power for a RME UCX, or any such device, but I suppose it does.
     
    Then you can go out with a red flashlight or white LED light in the middle of the night and record nature sounds (probably though with only two microphones) or use the unit the way you want to with a battery powered laptop computer. (a little humor!)
     
    RME UCX has 6 analog outputs (besides others for a total of 18 I think if I remember).
    And you would need a computer probably for the audio channels like a laptop computer running on battery.
    Anything else I do not know and I am not sure I know about this either.

    I appreciate all you guys' effort!
     
    I'm just trying to use as few wires as possible! Also, the when the source of audio is completely battery powered, you don't have any ground loop issues so you can get away with not using a D.I.! Just try plugging in the audio output from a laptop into a P.A. on a different ground circuit when the computer is plugged into the power, and then without.....
     
    I have an M-Audio Fasttrack Pro which has 4 analog outs and 2 mic pres. That can be powered over USB, so nobody is going to tell me it's impossible to make a unit WITHOUT mic pres but 6 analog outs instead that can operate in a 6W power envelope.
     
    Again, the goal is simplicity of setup. I'm running Ableton Live on a beautiful Dell XPS18, which can run on batteries for 5 hours or so.
     
    Thanks!

    Another run on batteries with USB 2 audio/interface.
    I doubt if it runs very long on 8 AA batteries. Four ways to power it.
    I have no idea what that involves.

    Roland Unit - 8 like XLRs analog outs.
     
    And then I suppose that means separate 8 outputs looks like, not perhaps like other units may be only 2 outs - L & R only but 4 connections.
     
    I recommend nothing without looking at the Roland site and examining the unit.
    Allthough that unit is marked 3 through 8 out where the other two are, I do not know.
     
    I see nothing else that has that many outputs that is a portable unit like the RME UCX or now that Roland unit.
    and they all cost a bunch!
     
    No devices for power that only run on USB 2 or USB 3 or Firewire only for the audio in and out, which the RME UCX unit runs on I suppose with an external battery or like the Roland Unit with its 4 ways to power the unit.

    That's it! You found one!
     
    As a matter of fact, this thing is the PERFECT backup for an 8-track Ableton track playing machine..... I'm gonna see if I can get my boss to buy one!
     
    Glad to know this forum still rocks!
