The MoCo from ESI is a completely passive monitor controller with 2 separately adjustable inputs and outputs each. The input signal can be selected via a switch. With the mono function, a downmix of both channels can be created and the signal is muted by mute. In addition, it is possible to switch quickly between the left and right channels using a push-button. The large control in the middle of MoCo controls the listening volume.
Actually it's the only unit i found, at least in this price bracket, that allows you to change between two sets of monitors while also facilitating multiple inputs.
Feels nice and sturdy.
Does the job. I'm happy :-)
So far, it has been a great piece of equipment to put in between my monitors and my audio devices. It feels expensive, it is very user friendly and it doesn't need power! If you need an affordable unit that can have 2 inputs and two outputs, look no further. Would recommend this to anyone!
