A 4 channel analog mic input card for Soundcraft digital mixers.

Four analog microphone/line inputs,electronically balanced,with 24 bit,44.1/48/88.2/96 kHz delta-sigma A/D converters (mic/line sensitivity,gain setting in 1 dB steps,low-cut filter,soft clipping and 48 V phantom power on/off controlled by console software); four analog split outputs (not used),electronically balanced. Green "signal present" and yellow "phantom power" indicators per channel. Inputs and split outputs on standard 25-pin D-type connector (female).
