Presonus Monitor Station V2
I just bought a new monitor controller as my old became bad in time. I had a cheap ESI passive controller. Now I bought the Presonus Monitor Station V2.
It has two sets of TSR stereo inputs, One S/P Dif coaxial input and aux Unbalanced RCA/ 1/8 inch stereo input. You can connect three sets of monitors and four headphones. The monitor outs have adjusments pots, so you can equal the volume of each set of speaker to each other.
On the headphone side you can choose either the main source or selectable cue source. Volume is adjustable per headphone out.
