Dayton DSP 408

Recommended Posts

Hi All,

 

I am looking to use the Dayton DSP 408 for some basic room/speaker correction.

Later down the track I may experiment (have fun) with going active.

 

I was just wondering whether anyone has experience with this DSP who could comment on its subjective sound quality, impact on the signal chain etc.

The software appears quite basic, although all required filtering and crossover requirements seem available (Without stepping into FIR's).

It's apparently quite serviceable. It's the same price as the minidsp umik-1 which apparently has better tolerances.

They are both compatible with room eq wizard. Look up Minidsp forums and room eq wizard tutorials to get an idea

I was asking about the Dayton DSP, not the USB measurement microphones. 

Thanks

Of course. I didn't read that properly.

I haven't used it so cannot really comment, but have a fair bit of experience with room eq wizard and minidsp plugins.

I assume that they are quite similar

Same processor as the original MD.

Hmmm.  Interesting, I had assumed it was not due to the channel count, and the listed SNR specs.

 

... but ahhh ... what they've done to get the channel #s and performance ..... is use 2x of the DSP chips (from the minidsp) .... and then they've added some extra ADCs and DACs in addition to what is already built into the 1701 DSPs.

I have a friend who said he uses the unit for an active speaker setup.

Apparently his experience is positive. Little to no background noise, and subjectively decent sound quality. 

I wonder if Paul Spencer from LSK could provide any insight.

 

He would no doubt have an excellent understanding v's miniDSP, Behringer etc

As long as your gain structure is good, you will get this.    Even more so on the Dayton than on the MiniDSP.

 

The big factor comes down to what setting you put in the DSP (ie. how you design your 'active setup') .  👍

Not with HE speakers. I had one, and now have 4x10HDs.

Interesting.

Just touching on Daves point, I think product quality (Power Supply, SNR, etc) is just as important.

In my experience product design/quality plays an extremely important factor in the areas of hiss and background signal noise. 

I have tried many DSPs in identical applications, and the pro units (Symetrix, QSC Core, BSS, Biamp) produce far less hiss and background levels than miniDSP in the same application.  

 

Even with input gain optimised, many Hifi amplifiers don't provide coarse gain adjustment for the output stages like commercial amplifiers do, which adds to the issues.

It is... from my (admittedly quick) glance at the spec sheet, I would expect the Dayton model to have better performance there.
