Waves Max Audio MX5000A - Manual (Page 6)

Preliminary
3.3 Digital Audio Input/Ouput
For digital audio I/O, the system supports three stereo inputs and two stereo outputs as
shown in Table 1. All inputs and outputs are synchronous with shared clock and synch pins.
The digital audio input/output is supported only in I
2
C Slave Mode of the MX5000A.
