AES/EBU Channel Status Data
The EQ1 allows to convert the incoming Channel Status Data as follows:

• From Consumer to Professional
• From Professional to Consumer
• Transparent mode, i.e. Channel Status Data is fed forward to the output without any conversion (one exception, see below)

The following tables describe how the output Channel Status Data Bits are generated in the various conversion modes.

Dithering algorithms are implemented using the POW-R set of algorithms, i.e. POW-R #1, POW-R #2, POW-R #3

MIDI Remote Control Protocol
All band parameters plus the controls parameters are remote controllable. Each parameter has its corresponding MIDI controller number. According to the different parameters, the controllers are limited in their range. Invalid values are replaced by the maximum allowable values. Details can be found in the EQ1 manuals.
