Important constructive criticism
I love this product but I have an important criticism that I hope Behringer will fix and that could be significant for some users.
I have my DAW interface connected to Input 1 via XLR and my laptop connected to Input 2 via USB. I love this because it allows me to listen to my reference tracks on CD through my monitors without having to fire up my whole interface setup. It just sounds fantastic through my monitors and through my headphones with a little "crossfeed" engaged.
Here's the problem. In addition to my main monitors, I have a single powered Behritone speaker that I use for mono monitoring at times when mixing. (The other reason I needed this.) I initially connected this to the Monitor 3 output which is mono. I am disappointed to say that there is cross talk, leak, bleed, whatever you want to call it of signal through this 3rd output channel when it is not selected. This is a bummer! This does not happen at all with Monitor outputs 1 or 2. I actually sent my first Monitor2USB back to Sweetwater to try out a replacement but it does the same thing. Despite this, there's nothing out there that compares to the Monitor2USB at this price point, so I'm keeping it. I just run an XLR Y-cable from the Monitor 2 output to my Behritone, it works great with no sound bleed at all, and I'm happy enough.
When I read about this device, I understood that all 3 monitor outputs were designed for full spectrum output. However, my guess is that the mono Monitor 3 output was initially designed for a sub only; the sound bleed I'm hearing is higher frequency and probably would be absent in a low pass situation with a sub.
Again, I love this product; I wouldn't part with it. Hopefully, Behringer will fix this annoying little flaw.
