Extended Range Compressor Curve Values

The extended range compressor allows processing of input values up to +23.999 dB. In Sigma Studio, if one sets the graph to flat, the capture window shows that the address values written past the +6dB point are such that the output would be limited to 6dB. For example, the value written for the +24dB address input is .125 or -18dB. 24dB - 18dB = 6dB limit.

 

In an actual application, if a micro-controller were to write 1 to all address values up to +24dB would the compressor pass the input signal through at 1:1 or would it continue to clip to +6dB? In other words, does the compressor limit to the last two points on the curve at +3db and +6dB regardless of what is written to the remaining addresses.
