The iDR0 is a 2U rack unit that provides all the processing features of the iLive system for networked audio systems. Instead of slots for I/O modules, the iDR0 offers two EtherSound ports, which provide all the audio inputs and outputs of the system. It provides cost effective and compact solution to users who wish to mix common sources for different applications such as FOH and Monitor, or need an additional mix for broadcast or recording that allows full processing and mix capability with the source material. The iDR0 unit is modular and uses the same processing PCBs as the iDR10, the mix rack which provides I/O and all processing and mixing functions with the current iLive system. Processing for 64 inputs, with full dynamics and EQ into 32 mixes with dynamics, EQ and graphic EQ is provided and can be controlled by any of the iLive surfaces over Ethernet. Provision is also made for the back-up power supply unit, iPS10, if required. iDR0 includes the new iDR-64 mix engine rack extra PCB, which provides the digital signal processing capability for the rack offering 8 effects engines, which can run system effects or can be inserted into input or mix channels. The iDR-64 mix engine rack extra module is also available as an upgrade to existing iLive systems.
