Pre-purchase help - HW and time domain q's

[eriksq]

Hi everyone,

These seem like stupid simple questions but I didn't see them answered in the Juice pages. I'm in the process of considering making fully active main speakers that would use 3-way plate amps from Hypex. Is this an easy target for Audiolense?

I'm also interested in using Audiolense with Roon, or miniDSP. Same questions. Easy to do?

Lastly, how easy and which versions is it to do time / phase correction? Can I get to an ideal step response with any version of Audiolense?

Thank you!

There is a learning curve to AL. No doubt. Try by looking into Mitch Branetts videos and articles to get an idea of how it's done.

You need Audiolense XO. With miniDSP you probably have to (and should anyway) create & run the crossovers with IIR filters, and let Audiolense work as a fullrange correction. This works fine, btw.

With Roon this should be fairly straight forward.

It can be quite easy getting started with Audiolense. The work flow is pretty well laid out for you. But it will be steep if you run into measurement problems. And in any case there is learning involved in understanding what's going on. And most users want to understand this.

Hi Bernt!!

Just a couple of clarifying follow ups. I fired up the Hypex Filter Designer, the Hypex crossover and EQ management GUI. I've used HFD manually to create a 3-way before.. but I absolutely cannot find a way to import anything besides a project. Is there a path like this:

Audiolense XO --> save files --> Import files to HFD?

or is it more:

Audiolense XO --> Manually copy biquads --> HFD?

PS - Sorry for asking such a variety of questions. As it is right now I have Roon and my L/R speakers are passive. My center channel is active. My L/R speakers will be converted to active sometime this year with the addition of a subwoofer tower under them with 3-way plate amp. So I'm trying to understand what paths are and are not available to me.

I forgot to respond to the 3-way plate-amp. I am running a pair of two-way speakers driven by plate-amps from Hypex myself. I did set up a correction and crossover the Hypex way first, with IIR crossovers and some voicing ... without being too picky about the voicing. Then I measured and corrected these as a pair of full range speakers using Audiolense. This approach works really well. You get most of the benefits of digital crossovers, and I am not even sure if the part that's left is audible.

The alternative is to bypass all the digital parts in the Hypex powered speaker, install one terminal for each amp channel / speaker driver, get a mulltichannel sound card and let Audiolense do crossovers as well as everything else. But the combined approach works really well.

If you want all the crossover duties to be handled by Audiolense fyou need a multichannel sound card that has as many drivers and subs as your system holds, and each driver has do be driven by its own power amp channel. But Audiolense generally works very well with passive speakers, active speakers and various forms of bass manegement outside the PC. So you just configure the speakersetup the way it is seen by the PC and then you're on the right track.
