Is the M2000 a 20 or 24 bit unit? Which bits rates will it accept and which bit rates will it output?
If it's a "Mark 1" M2000 with a serialnumber lower than 1110000, it has 20 bit AD/DA converters. However, as the internal processing is done at 24 bits, it will accept 24 bits on the digital inputs and outputs.
If it's a "Mark 2" M2000 with a serialnumber higher than 1110000, it has 24 bit AD/DA converters.
