10 IDR-8 User Guide
System Processing Overview
The iDR-8 has 8 analogue inputs and 8 analogue outputs. However, it has the onboard processing for
a full 16 input and 16 outputs when operating in normal 48kHz mode. The extra 8 inputs and/or
outputs are available when the iDR-in and/or iDR-out audio expanders are added. Only one of each
may be added. This means that you can create an 8x8, 16x8, 8x16 or 16x16 system to suit your
requirements. The stereo monitor input and output can also be added into the matrix in a non-
expanded iDR-8 to create a 10x10 system. iDR-8 units can be daisy chained together using the 8
channel wide digital expander bus to create even more flexible systems with additional local inputs and
outputs and a maximum 16x16 matrix.
48kHz and 96kHz modes The full 16x16 matrix is available in 48kHz operating mode. The expander
channels are not available when the unit is operated in 96kHz mode. In this mode an 8x8 matrix is
provided.
The 48kHz system architecture illustrating the expanded iDR is shown below:
The 96kHz system architecture is shown below:
