Hello greetings from a windy cold flatland.Today i opened the bought DATS v3 casing and looked at the board.My Dats is from 2023 (See picture).It also has the 1000 ohm calibraton resister built in.It has only 1 LMV op amp.
For the reference cal value i took a precision resistor of 100Ω first. Later i used a 4.952Ω closer to minimum impedance speakers. REW shows fairly accurate down to 0.2% 0.4%. Dats shows approx the same values.. REW with dats is somewhat more noisy but averaging should help.Higher sweeplevels -4db help too.
I'll post a comparison of the solo Dats vs REW-with dats later with higher resolution.In Rew's the impedance peaks (Most clearly the left one) shows 1ohm higher then dats is measuring.
Not shure if this is a large value or not.... I'm just starting with this measurements and threw away most cause i need to know if i'm doing it right. I didnt take any free air measurements yet to find T.S parameters.
The purpose is to get familiar with this stuf so i measure the speakers in box now and later on measure the seperate components of the crossover filters and speakers.This is a stereo system with 2.5 way floor standing speakers .nahh .with some 20+ year old elko's witch i want to replace/upgrade. I wil only take comparison measurements using dats vs rew-with-dats.Measuring with same room temperature and speaker placement. so no impedance RIG.. I'll try to get the levels about the same.
I have a modified behringer DEQ2496 ultracurve (parametic eq) where the "grainy sounding " output stage is bypassed.Signal goes out direct via highpass filter and coupling caps.All is done with online help.Im not much of a techy but know some tiny basic stuff.My L-shaped room is far from ideal and plan on doing some accoustic treatment in the future.I listen in a fairly small triangle (speakers and me) to reduce room interfearance and let early reflections not take over.Thats it for now.Time for bed.

Hello and welcome!
You will have more specific answers once you post your question in a dedicated thread, maybe in the equipment and tools forum!

Thanks for your suggestion stv,
yes i will try to find the right thread.. Would be great to get some answers from Olen who wrote the manual for using DATS in REW. I read that the first "introduction post for new members" should be about introducing yourself and not to ask questions...I read it a little bit late tho.Had to rewrite and cut my not yet submitted post for the introduction ha. No problem. stv, are there limitations for a new members for instance contacting a specific member through diyaudio forum or the possibility to start a new tread? greetings John

I think creation of a new thread will be moderated until you have posted a certain number of messages, so if you start a new thread it needs to be approved "manually" and unlocked by moderators which may take a little time.
Starting private conversations is also unlocked after some time or a certain number of postings.
But you can adress any member in a posting by typing "@" in front of the user name: @John64
The user will then be notified.
Have fun!
