So I went to a live 2 day class for learning more about tuning and the differences between helix dsp's. It was quite interesting. The main things that stood out were the the many detailed parts of the tuning and the caparison between the dps pro and the ultra. I am now going to go đź’Ż ultra. It's the closest to Brax just thousands of dollars cheaper. I am a total noob but may be able to help someone who has some questions regarding the dsp's or even focal speakers

  • Just figured that I might have picked up on something that may be of help to someone. I'm not claiming to know it all. It actually made me realize how much of a newbie I really am. These days I'm more interested in learning and knowing how things work rather than just getting the perfect sound. Every vehicle is different as you know

It really comes down to what you are running with it. Like, 3 way front stage? 1 sub? ,amps, deck, crossovers and so on. What are you running and are you using high voltage on your current dsp? The dsp features like real front center and xclarity are great. Although I wasn't able to hear it in my truck the side by side comparison between the helix dsp pro mk1, mk2, and ultra. By far the ultra sounded much better by far. Especially between the mk1 and the ultra. I will be programming an ultra in middle may and will have hands on experience. If you are using passive crossovers you might as well not wasting your money. Only full active with decent amps. I suggest mosconi but that's just my opinion

I don't recognize either name. Nobody from our company seems to know him either.

I ask because I am the Director or Technical Support for MSC America America, the North American Distributors for all of the Audiotec Fischer brands and we should know when people are training on our products. We would likely support them and send folks out that know them inside and out and make sure that everyone gets the best information possible. We are in constant communication with the engineers and the rest of the company so we are as up to date as anyone.

I am in the market too for a Helix DSP too!, I did a post a few days ago and everyone said the DSP.3 and up to the Ultra have the same software and tuning capabilities, the only difference is how many channels they have. I called an audio store in Irvine, CA.....they told me to go with the Ultra for my basic system because it has the newest software on it....$1,400 and had optic cable. I came on here and everyone said the DSP.3 would be just fine for my system. I am running hertz mille active fronts with audison quattro amp, hertz coaxial with audison amp for rears and 1 JL audio sub with Amp. Installer said the ultra is a must, I come on here and everyone said DSP.3 was plenty. G

there are situations where the Ultra is necessary even though you don't need the output channels. That said, i don't think this is it. I guess that depends if your front speakers are 2 way or 3 way

As much as we would love for them to sell a DSP ULTRA every time, it just isn't necessary. It has more advantages than just the extra channels, but many of the advantages are related to the extra channels. The DSP.3 sounds like it would be perfect for you as long as the inputs work for you, and you mention optical, so I assume they will.

Virtual Channels are the biggest difference between the two DSPs you mention, and they are far more useful in a complex system. That isn't to say that they aren't handy. I'll likely use a DSP ULTRA in any system I build just because of its capabilities and the Virtual Channels. The high level inputs are quite different as well, again you mention optical so I assume you are using a Helix, NavTV or Mobridge interface for your factory system.

The main reason that someone would use the high-level inputs on the Helix is out of necessity... Not everyone has low-level outputs from their headunit. If you are using a stock head-unit, for example, which doesn't have line-level outputs, you'd have to use it's speaker outputs to feed the Helix.

Really, that is the only reason I can see that someone would use the high-level inputs - if they absolutely had to because they didn't' have any low-level outputs from their stock head-unit.

Running high level speaker signals from my stock headunit when I want to use the stock DTS processing for passengers.

The speaker level inputs are actually where I most noticed improvement in the Ultra when upgrading from the Pro MK2. For my ears, the more robust and improved speaker level input board preserves more of the speaker level signal fidelity than the Pro mk2. Not tested or measured in any way but I did not notice this difference when upgrading from Pro MK1 to Pro MK2.

The dials inside the DSP are input gains that are suppose to be adjusted to the voltage range of the speaker level signals your feeding it.
