The Roland/RSS V-Mix may be a good choice for many applications but it can be a bit awkward to implement in others, especially in existing systems. Unlike the Yamaha consoles discussed, the RSS M-400 has minimal direct I/O on the console (8 mono analog and a single unbalanced analog stereo for inputs, 8 mono analog and a stereo SPDIF/Toslink for outputs) and relies on digital snakes and stage boxes for all other I/O. This can be great if your system supports having the mic inputs at stage or other locations but not as effective if all your cabling runs to the mix position. Also, only one of the RSS stage box options supports anything other than analog audio and that is limited to AES/EBU digital, there are currently no Aviom, CobraNet, EtherSound, ADAT, etc. options (and since some of these are essentially direct competitors to the Roland digital snake products, it does not seem unreasonable that they may never be supported). Again, that may work fine for some applications and be a problem for others. So like any console, just be sure to consider both the operational functionality and the physical implementation aspects.
