Summary: I replaced a Mackie 1202 with this unit when I went to all software instruments for recording. Plenty of ins and outs, and I can discern no difference in sound quality or noise level. I run a pair of big powered monitors out of it as well as headphones. Behringer gives great value and quality especially for prosumer level recording. Have used for a year now with zero problems.
Summary: Like others, I'm using this as part of a small home recording setup. In my case, mics and sources connect to a Behringer UBB1002 mixer which feeds a Creative E-MU 0404 USB audio interface. The MON800 inputs are connected to both the mixer and the audio interface so that I can quickly switch from monitoring the live mix to monitoring playback from the audio interface.
Summary: I have a PC monitor in my kitchen, which has VGA, S-Video and RCA Video inputs. I hooked up a digital TV tuner, a computer, and a video feed from my amplifier which is in the living room. But I needed a way to combine the audio. This does the job. Using a switching power strip, when I turn on the monitor, the MON800 turns on. Now I get the sound from the DTV tuner, or I can fix dinner while watching what's on the DB-player in the living room.
Summary: I just recently replaced this device only because my new board has a built in monitoring section, dual headphone outs and talkback features on it. For the price you won't find anything better than this. It includes everything you need for monitoring without having to drop 3 bills on a Big Knob. They're definitely better but should cost 80% less compared to this. I've had mine for 2 years before I upgraded to my Alesis Master Control a few months ago.
Summary: I was searching for a way to go back and forth between the monitors and the headphones for recording and all saw was $100-$500 devices that were way overkill. This device does that perfectly. There is no added noise, it's convenient, small and very inexpensive. My setup: 2x Mics, guitars -> Behringer Xenyx 802 -> PC with EMU 1212m Emu 1212m -> MON800 -> Behringer B2031A monitors -> Headphones Perfect.
Summary: This is a nice little product, and I own other Behringer products - I've always been impressed by their quality vs. price. However, I am a little disappointed in this item for a simple reason - it's noisy. I have a quiet system, but when I ad this unit - I get a buzz. I've tried to isolate and remove the buzz, but the only thing that works is removing this mixer. It also picks up interference and electrical pops, that weren't there before I added this.
Summary: Simple, straight forward, does all it says - for not a lot of green. An extra star for the fact that it is the cheapest talkback headphone "system" BH sells. Build could be heavier but what can you really expect for the price?
Summary: As always, with Behringer you get an excelent cost-benefit balance, if you need to use/compare 2 or 3 set of speakers/monitors this is a very nice solution, it has small things that I would add (like a capability to route the mixes ) but for the price there's no equal.
