We have gone from 14 and 16 bit to converters with 20 and 24 bit word size. Your analog console doesn't care about sample rates, word size or new formats. It can work with many different formats at the same time without inflicting a lot of brain damage. You could get a small digital console and plan to trade up in a few years, but size does matter. Little consoles just don't have the drawing power of a big analog console.
Some digital consoles radiate digital noise that can effect other equipment and degrade sonics.
Not only will your analog console protect you while digital technologies continue to change, many engineers find that having dedicated controls for each function make analog consoles easier to use. Your analog console is probably paid for, too. Flying Faders is our 'Just Mix' moving fader automation system that, when retrofitted to a console, has a proven track record of attracting more sessions at a higher rate. Our ACX automated console expander lets you book sessions that need more automated channels than your console has. MultiMAX is an inexpensive multiformat, multi-speaker controller that replaces your console's monitor section so you can attract surround sound customers.
