    Poor - Updat

    Overall: 2 out of 5

    Note that playback is fine.. but record level is NOT to any known standard. Pro level (balance) line level hits this thing as if you a driving a mic input. But feeding a mic into this is far too low to drive it. I had to put a 16dB attenuator (pad) on the input to make line-level balanced audio work on this. NOTE TO MCM: IF you want to make customers happy who purchase this beast, include two 15dB attenuators (you sell them). I had to buy them from you.. but you should have included them since this thing is far off from any normal specs.

    Fine for Playback... TERRIBLE for Record

    Overall: 2 out of 5

    Another bad design issue. The two XLR inputs don't know if they're Mic level or Line level. Well, in fact, they're neither!! They're about half-way between the two. Mic sources are too low for these inputs and the line level stuff is far too hot. Of course I can get into the audio settings within Windows and adjust, but I have to put my mixer at "1-click" (nearly off) to get even a distorted audio at a proper level. MCM should include XLR audio pads with these for free.. plus go back to the manufacturer and tell them to FIX IT! This is the second product in a large order that had terribly poor quality (a rack case with WOODEN rack ears?! was the other).

    BEWARE: Inputs are OUT OF PHASE!

    Overall: 3 out of 5

    For the price, this is a pretty good audio device, HOWEVER --- The INPUTS are out of phase. To fix, you will need to swap the red and white wires in ONLY ONE of the female XLRs. This will require solder and a soldering iron.

    The other issue is that the levels are NOT +4 dBm, as one would expect from a device that has XLR connectors. It's more like -2 to 0 dBm, so 4 to 6 dB lower than expected.

    Defaults to Mic level on inputs

    Overall: 3.5 out of 5

    Using Win7, I have no success getting this interface to permanently stay on line level in. There is no documentation, and no additional drivers available for it. The lack of the ability to record with this interface at a +4 audio level is a deal-breaker. Such a shame.... Hopefully MCM will go back to actual manufacture of this thing and get a driver that will offer +4 recording levels.

    Works - But.....

    Overall: 4 out of 5

    This USB dingle works without any additional software. Does not require any external power. Quality seems find but I have not done a freq response run on it yet. XLR connectors for both input and output. ABSOLUTELY NO DOCUMENTATION PROVIDED. Read the product description and you will find which connectors are the inputs and which ones are the outputs. That is the easy part, Product is offered as as TWO CHANNEL - most applications will really be stereo left and right.. The only way you can find out which connector is the left and which one is the right is by trial and error. Called tech support at MCM and they do not know either. You will have to connect to a computer - send audio in on one channel and listen/measure for the output connector with audio. Then send program or music from the computer on ONE CHANNEL only (ie:left) and listen/measure to find the left.
    Frankly a whole lot of effort that could have been prevented with a little common sense at the design/manufacture stage.
