Monitor System Controller with RMC Room Mode Correction


The MSC1 Monitor System Controller includes essential "Monitor Strip" features found in large mixing consoles so you can take control of all monitoring functions from your place at the mix position. Since the acoustics of the room can play a big part in what you hear, the MSC1 includes JBL's highly acclaimed RMC Room Mode Correction Technology to tune your monitor system to the room. The end-result is a calibrated reference environment in which your speakers work in harmony with your room to take the guesswork out of mixing.
