What is the difference between the MR816 CSX and MR816 X?
Basically the MR816 CSX and MR816 X are the same device. The only but not unimportant difference between those two units are the eight DSP-powered channelstrips that the MR816 CSX provides. The innovative Sweet Spot Morphing Channel Strip is a unique new compression and EQ tool that runs on DSP inside the MR816 CSX. All other features of the both units are the same: Both provide best sound quality and outstanding preamps as well as the same quantity of inputs and outputs. Also MR8168 CSX and MR816 X offer one REV-X reverb, a complex reverb algorithm developed by Yamaha which provides a high-density, richly reverberant sound quality, with smooth attenuation, spread and depth that work together to enhance the original sound.
