3.1. Single
unit
An iDR-8 or iDR-4 can operate as a single stand alone unit.
3.2. Daisy
chain
The audio from the first iDR unit in the chain is transferred to the following units via the A&H digital
audio buss in a unidirectional stream. This CAT5 connection carries a maximum of 8 channels at any
moment. There can be a different combination of 8
channels in each of 250 available presets.
Many iDR units can be chained and iDR-8 can be
mixed with iDR-4 in a combined system.
Each iDR unit runs its own separate System
manager software session and each unit is
programmed individually.
In a chain, the first unit
automatically becomes
the sync master.
