=== Notes ===

While the mixer is just great for the price (british technology, high quality parts, assembled in China), the USB-Interface is limited to 16bit at 32/44.1/48kHz stereo in- and outputs (USB 1.1). ALSA mixers show just a PCM fader for USB output, capture level is set on the ZED-18. \\
There's a silent but still annoying treble noise appearing on the headphones mix when JACK is started on that device (has also been reported when used under different OS), but it doesn't affect the recording or Main/rec-out mix. So think of the USB interface basically as a nice add-on to a very affordable professional mixer.
