Plug-in module converts the XLR inputs and outputs to AES3, providing 2x in on two XLR-Fs and 2x out on
two XLR-Ms. The Nx12 provides 4x in on two XLR-Fs and 4x out on two XLR-Ms by using both channels of
AES signal.
Sample Rate Converters on all inputs and outputs. Inputs can accept 32, 44.1, and 48 kHz rates. Clock for
outputs may be sourced from the AES inputs or internally-generated, locked to the ISDN network.
