8-channel AD option card for m908 for analog input channels 9-16
The m908 can accommodate up to 2 8-channel ADC modules. The ADC accepts 8 channels of balanced audio on a DB25 connector and also two channels of unbalanced analog on RCA phone jacks and two channels of balanced analog on XLR connectors. The RCA and XLR connectors are relay selected as alternate sources to channels 1-2 of the ADC. If one ADC option is installed in the m908 then the two stereo connectors are installed as well. The second ADC option module only has 8 channels in on DB25.
The stereo inputs on XLR and RCA jacks route to ADC channels 1 and 2. If an input is defined to use these connectors the ADC1 channels 1-2 can not be used at the same time.
