The PreSonus Central Station Plus is a prepackaged bundle of the wildly popular Central Station monitor controller and the CSR-1 Remote Control. This passive monitor controller lets you switch between one digital input and three sets of stereo analog inputs -- DAW, CD player, mixer outputs, whatever you've got -- and then three sets of monitors with mute, dim and mono controls. The Aux input on RCA connectors features its own level control to volume match input signals for true A/B comparisons. Need to talk to the band? The Central Station's got talkback facilities built right in which feed the two headphone outputs on the front panel.
