ANALOG MICROPHONE INPUT
The DSP block Analog Microphone Inputs provides access to the eight analog inputs with microphone
in- put sensitivity of a MI-1 Microphone Input card. Establishing independent settings for each input channel is
possible. Equivalent to the ones of the Analog Line Inputs DSP block, these settings include a fader with ramping
function as well as Mute and Invert buttons. In addition, setting the GAIN in steps of 6 dB is possible in a range
between 0 dB and +60 dB. +48 V phantom power can be activated per channel. Adjacent channels can be linked by use
of the LINK button. This allows convenient synchronous settings of several input channels, e.g. for stereo signals. Up to
three MI-1 can be used simultaneously in a N8000 or P 64.
