Has anyone tried running a CLRdsp into another CLRdsp and “double processing” it?

I wonder if the two different algorithms on lighter settings would work better?

I have two CLRdsp units for my two 7300’s and can try what you suggest. But the units have the same algorithms. As I stated in my previous post, I cascaded the CLRdsp with the NR in the 7300 (different algorithms), both at lighter settings with decent results. It seems to reduce the time frame “whoosh” of the noise abatement adaptation when changing from transmit to receive.

Great, let me know how it works. I realize the algorithms are the same. I was thinking that once speaker 1 processed it, speaker 2 would choose an algorithm with a different attack pattern.

I could be wrong in my assumption of how the units work.

I'm not sure what you mean with the speaker 1/speaker 2 scenario, as a unit can only feed one speaker or headphones. They each have a 10W audio amplifier, so I'm not gonna cascade one output into another's input. Maybe you're referring to the models with the built-in speaker? I have the stand alone models, needing external speakers.

Got you, I wouldn't run 10 watts into the input either; it would have to be attenuated for sure. Is there a volume for the output of the unit? I've only used the model with the speaker built in.

Yes. You adjust the radio’s audio volume control to a point that won’t cause clipping on the CLRdsp (red LED light), and adjust the CLRdsp volume control to your liking.
