6.2.3 HD Mic/Line In Card ( and ) A949.0447
Four analog microphone/line inputs, transformer-balanced, with 24 bit,
44.1/48/88.2/96 kHz delta-sigma A/D converters. Four analog split outputs,
electronically balanced. Green ‘signal present’ and yellow ‘phantom power’
indicators per channel. Mic/line sensitivity, gain setting in 1 dB steps, low-
cut filter, soft clipping and 48 V phantom power on/off are controlled by the
console software. Inputs and split outputs on a standard 25-pin D-type con-
nector (female).
Notes As opposed to the Mic/Line Input card A949.0427, the gain of the split outputs
is always unity, i.e., 0 dB.
This card does not support the Analog Insert Card A949.0428.
