I've just been playing with my power amp and thought I'd share my experiences in case it's of interest or benefit to others.
I have a Crown power amp, and there are several factory presets, but I always wanted to see how to create my own on the computer and sync with the power amp.
There is a confusing array of software related to Crown. First I tried Band Manager, but it never loaded up successfully. Then I tried System Architect, but it wouldn't recognize that a device was connected. Finally I tried Audio Architect, and after a simple-to-execute firmware update, all was ready to go.
The plan was to create a series of 'Boombusting' presets, i.e. cutting a specific frequency with each preset to try to eliminate any boom. As I understand it, the different shapes and sizes of venues may cause unwanted bass boom. The boom can originate anywhere between 80-250 Hz, and finding out the exact frequency can be a lucky dip.
So, I've created five 'boombusting' presets as follows:
-6db@80Hz
-6db@120Hz
-6db@160Hz
-6db@200Hz
-6db@250Hz
If I do detect boom in the room, I'll try each of these presets until it vanishes, leaving clean, smooth pure bass. That's the theory anyway.
Here's a screenshot showing how to set the EQ:
To be honest, it was more an exercise in having a play with the amp's capabilities - I don't get bad boom, but I'll have a play with the presets anyway, and it's nice to know that I can bust that boom should the need ever arise.
