Don’t know what the sound pro with volume issues was talking about. This device actually increased the volume on my keyboard setup to where I had to back it down about 30. I use the through outputs to connect with a mini mixer to which I have a small mic connected. In this way I can hear what is happening on stage and get a real stereo mix through earbuds, even though I mix down post direct box to mono via a XLR to mono adapter. This really helps when you’re playing live. Used the ground lift on both channels and it totally erased a slight hum. Really a nice affordable little stereo (or two channel) box with a tough aluminum case. Love the nutless inputs too. Nothing to retighten. Totally recommend it for pro keyboard.
