Soundcraft 4ch Analogue Mic Input Card for Vi Control Surface Option

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).
