Total quality: 4 stars, because it is not a device you should take with you on the road. It is (probably) not sturdy enough. I use it at home, so not an issue for me.
The sound, features and handling is excellent for what I needed.
I was looking to be able to use / combine my 3 speaker sets with one of 2 sources, without having to plug / unplug cables.
what I wanted is
- able to switch them on/off independently
- balance their volumes with a one control per set
- manage total volume / pan with one control.
- from 2 stereo sources ( usb audio interfaces connected to 1 PC/DAW )
source 1 is a behringer 204HD , connected to a mixing table with a lot of instruments. (guitars, kbd, drums, bass, 2 synthesizers )
source 2 is a behringer 202 UFO, as a simple sound card attached to my PC/DAW
source 1 is connected to the headphone out of the 204HD
source 2 is connected to the RCA output of the 202
speaker sets are connected on the back of the AMP800 to headphone out 1, 2 and 3. ( stereo jack<==>RCA converter plugs)
4 has a headphone :-)
I can now independently, without unplugging/rewiring balance the volumes of the 3 sets ( 2x B&O and 1x Wharfedale ) and control the general volume of all 3 with the volume / pan of either :
the A input = 204HD/mixer (source 1)
or
the B input = 202-PC sound (source 2).
Using both 1 and 2 simultaneously , each directed to their speaker set(s) is also possible, of course...
I am using 6 mm jack-stero <==> 2x RCA converter plugs for better connection quality (compared to jack 3.5 mm) from the headphone connection 204HD to the AMP800 inputs
and 6mm jack TS mono <==> 1x RCA converter plugs to input the A and B inputs of the AMP800
Behringer used to have a device to do exactly this, but it is unfortunately out of production. The one they have now is a lot more expensive....
note: if you need to connect more than 4 targets to source A, you can link a second AMP800 to the first one via a special output. E.g, in a large room with more speakersets ?
