Hope all are well. I want to get another monitor set-different than my currect ones (Mackie HR624MKII's which I am vey happy with. Not sure if I will go up to 8's or down in size.
 
Issue is a monitor controller for 2 sets of monitors. Just something that lets me switch between the 2 sets, adjust volume on either and also lets me mute both if needed.
 
Thanks very much folks

I've got a set of JBL 2328. There is a 5" version available as well as a sub and a controller. They are powered and the controller allows upto 3 inputs and outputs as well as room correction. The controller is supplied with a reference mic.

Without going into Adam type prices I've found them quite good for the price.
