iLive iDR-32 MixRack is the heart and brain of the entire iLive system. It includes a mixing processing unit with a 32-input, 16-output architecture along with control/audio networking interface. The DSP can be configured as mono/stereo and by type (group, aux, main, matrix). The system provides full dynamics, equalization, and delays for all inputs/outputs including the main output. All MixRacks have the same processing power and differ only in the physical number of microphone/line inputs and XLR line outputs. Expansion cards for network audio communication can be installed in the internal Port B, allowing for system expansion and digital split of microphone inputs. The iDR-32 offers 32 microphone/line inputs and 16 line XLR outputs. It features an Ethernet switch with 3 ports, MIDI input/output, PL-Anet port, headphone output with volume control, ACE network interface, internal power supply (iLive iPS10 can be used as a backup power supply). All of this is housed in a 6U rack chassis.
