Very good

This thing is built like a tank and does the job.

Both the outside and inside of this unit look great! Heavy steel case, quality components, only a few hand soldered connections, transformer is securely glued to the circuit board. Nice diagram on top making it very clear how things are connected. Everything including the switches are CLEARLY labeled (in my opinion some aren't or you can't tell which position of the switch(s) engage a particular function). I like how the attenuation switch is reasonably well protected from getting bumped/changed during handling between gigs (some have push button switches that look like they could be easily changed by accident) Tested it and the attenuation switch operates smoothly with no noise or fussiness. Frequency response was measured to be 3 dB down at 5 Hz, almost no loss at 20 Hz; at the high end, less than 1 dB loss at 20 kHz.

Very well constructed! Beefy metal case. Heck of a deal. No noise and I'm a busy musician.

This box did not work for my digital piano, a Casio CGP700, a cousin of the Casio Privia pianos. There was no low end at when connected to my church PA system. It is quite heavy, looks good quality, but it just didn't work, unfortunately. I suspect that my Casio is a very picky keyboard, since the Behringer didn't work either. The only one that I know works is the Whirlwind IMP2.

Use this for live capture of electronic keyboards. Have used this unit in extreme EMI environments, like several hundred feet from a full power FM transmitter. No problems, no increased noise, no noticeable frequency degradation.Very solid steel case and otherwise solid construction. I'll give this one two thumbs up for live use. Best value for your dollar for this type of unit.
