I used the last 15 days to attack BW802 s1 (see this review) it is controlled by a Behringer DCX2496 (see review). It availing oneself of direct inputs into 6 or 8 channels. I first verifies its operation in stereo with the automatic adjustment using the supplied microphone. It works very well. The advantage of Yamaha in stereo effects are enough parameter and is the only amp I test o one is not tempted to return to pure direct mode after several hours.
In my case I do not use these non-compatible direct.
The result is very good and I recommend this solution for changing active amplification.
We gain in flexibility, optimum damping of HP (more than passive filters) must connect directly to the HP's. We are left with the equivalent of an amplifier with 2 x 300 W!
The report price is excellent quality second hand 200-250. Although this sr price was not the LATEST revolutions no HDMI standards, this is essential, you see!
I have not found the sound YAM loud as I could read, I recommend it for this type of application. It does not heat too much like other brands. It can be used easily without remote control and monitor. There is a button easily accessible front-line input-essential (vrifier power up) because if it returns to the "effect" with my config, it breaks the high level provides tweeters. The bass sound of hand channel is redirected to the surround channel (APRS treatment) are connected o the acute and there is no crossover at all, the coil tweeter live.

A good buy then!
