Unlike other Digital consoles, Soundcraft Digital 328 offers a mic or line input on each of the 16 channels, using Soundcraft’s UltraMic PlusTM preamp. There is also an optional mic pre-amps box available which allows 8 or 16 additional mic preamps to be added, (using one or two of the TDIF connectors,) giving a maximum of 32 mic preamps per console.
