I always disable the amp crossovers when going active in DSP.

Otherwise, it would be cascading multiple crossovers which will make tuning more tricky.

 

Ok cool, still need to turn up the gain on amp right?

 

looks like you can just set your crossovers to "off" according to the amp manual. And yes, you still need to properly adjust the gain.

 

On my amps the crossovers can not be turned off, so i basically set them to the largest span i can. Like the low side as low as it goes and the highs as high as they go so i can get as close to full range as possible, but the only issue is like Subterfuse said is that the actual crossover settings would end up being different then specified by the number, so using something like REW should be used to actually dial the crossovers if you want to use a certain frequency.

 

If you don't have the option to disable the amp crossovers, then that would be exactly my recommendation.

Set the amp crossovers way outside the range where you plan to set the DSP crossover.... so that you can minimize the interactions inside the passbands.

 

Thanks guys for your help.

 

Hey I'm back with a few questions. How do I turn off the amps crossovers since I'm using the Audison Bit one " clone or full range switch"?

Also the Audison setup wizard says to turn up the HU volume to the maximum undistorted level which I set up to 38 out of 40 & for some reason the music sounds pretty low between 18-32 while driving especially on the high way. I have to turn to max volume which I don't like and the amps gains are half.

Before I had the volume maxed on the wizard I think around 28 and gains were half & it was loud but was creating more engine & hissing noise.

Full range is the correct setting when doing active crossovers via DSP. But you must be careful not to feed too much bass signal to high frequency drivers like tweeters and damage them.

That is correct. The source needs to be playing at maximum undistorted volume during setup. If the source volume is too low, then you will get noise floor hiss.

The Bit One comes with a DRC volume control. The source volume should be "set and forget." The volume should be controlled via the DRC.

Yes, that's what happens when the source volume is not maximized during setup. The Bit One will attempt to boost signal and the signal to noise ratio is not good. The hiss is the noise floor.

Set the source volume to Max undistorted level and run the setup wizard again. Then use the DRC to control volume.

Cool thats how i have crossover at full. Also how do i get rid of the hiss & engine noise its almost gone but still could barely hear it when a song finshes playing?

 

Set the gain on your DSP to lower than zero. Ideally like -10. That should get rid of the hiss

 

The gain on the amp will have more effect on hiss than the gain on the DSP.

But more importantly; "Did you really open an account, just to respond to an 8 year old thread...?"
