The most complete and easy-to-use audio test system toolkit is now better than ever! Dayton Audio's DATS V2 is a powerful, versatile measurement and analysis device -- now with improved performance and stability!



Grab and go!

Any engineer knows that valid and accurate data is crucial to great results. DATS (Dayton Audio Test System) V2 is the essential tool in any speaker designer's or audio engineer's toolbox, providing accurate, precise measurement data for any audio transducer or loudspeaker system. Save yourself time, money, and trial-and-error frustration by using DATS V2 to measure loudspeaker drivers, crossover networks, and complete audio systems!

DATS V2 is a unique, multipurpose test system that works with your PC and full-featured test software to measure the impedance response of a speaker driver and derive a complete set of Thiele/Small parameters that describe its operation. It's as easy as connecting a driver and starting the test! The DATS V2 measurement module provides the electrical stimulus to the driver, measures the driver's impedance on the fly, and then creates a high-resolution graph (30,000 data points!) with no additional hardware required.

DATS V2 software is the true power of DATS. The included software not only measures impedance and parameters of speaker drivers with incredible accuracy, but it can also measure the true value of inductors, capacitors, and resistors, and it also works as a signal generator and scope to let you monitor small electrical signals (line-level only).

What's better about Version 2?

NEW in the DATS V2 software are the ability to measure Wright Parameters (Kr, Xr, Ki, and Xi) for precision speaker simulation, and the ability to display and print impedance data using a logarithmic scale. The precision of capacitor measurements also gets a boost from the newly added ability to measure ESR, dissipation factor, quality factor (Q), and loss angle (sigma), for complete characterization of passive components.

The new DATS V2 hardware eliminates warm-up and cool-down times, and is more stable than the original DATS, for uninterrupted measurements. It's also recognized instantly and configured correctly by your PC with no lengthy setup. DATS V2 also complements other, more expensive test gear by being easier to set up and use, and much more portable -- you can plug DATS right into a laptop! When used together with Dayton Audio OmniMic, you can take a fully-featured electro-acoustic lab anywhere you go.

DATS V2 provides the following unique advantages:

•Ultra-linear impedance response measurement for loudspeaker drivers and complete systems

•Accurate measurement of loudspeaker electromechanical parameters (Fs, Qts, Vas, and many more)

•Measurement of advanced Wright Model parameters (Kr, Xr, Ki, Xi) for precision simulations

•Precise, high-resolution impedance response measurements with 30,000 data points (1 Hz to 20,000 Hz)

•Save and compare up to 20 impedance graphs simultaneously within one test file

•Integrated quality control feature set provides pass/fail parameter measurement (QC Pack)

•Sensitive rub and buzz detection functionality reveals hidden flaws in individual drivers (QC Pack)

•Software signal generator with selectable waveform, frequency, and amplitude

•Generates sine, square, triangle, saw tooth, impulse, pink noise, and log sweeps

•Oscilloscope software mode with dual traces, plus adjustable time and amplitude scales

•Oscilloscope and generator modes are compatible with other audio interfaces

•Quality test interface hardware assembled using precision SMT components and automation

•High-quality alligator clip leads minimize contact resistance for improved consistency

•Includes method for calculating Vas from specified Mmd

•Faster-than-ever hardware startup time virtually eliminates warm-up/cool-down

•Software is compatible with Windows XP, Vista, 7, 8, or 10 with no added configuration needed

A solution like no other

DATS V2 is faster, more elegant, more versatile, and easier to use than any other tes t& measurement device. Get ready for your designs to make a quantum leap, thanks to better data!

DATS V2 software is backwards-compatible with the original DATS and WT3 hardware via a software setting. (Note: DATS V2 hardware is not backwards-compatible with DATS or WT3 software, due to an updated internal design).

Minimum System Requirements: IBM PC or compatible system with 64MB RAM; 500 MHz Pentium III processor; MS Windows XP, Vista, 7, 8, or 10; One available USB 2.0/1.1 port.

Would like to thank TLSK team for assisted me well, definitely will purchase from them more after this. good job guys!

Easy, accurate, brilliant!

DATS is incredibly easy to use. It took me 5 mins to set it up and was instantly measuring Theile-Small Parameters and Impedances on my drivers. No more guess work! I also tested a lot of my resistors, inductors and capacitors and it was quite eye opening to see how accurate (or inaccurate) some of the manufacturer's spec's can be. Also of note, I measured a number of run-in Dayton RS255-8 drivers. I have to say the proximity of the measured spec's to the manufacturer spec's in amazing.........

This is my first experience with the DATS, but on initial testing of drivers, with known specs, and from respected manufacturers, the DATS returns very similar and constant results. I assume this indicates that the DATS is doing its job well. Also, the LoudSpeaker Kit were a pleasure to deal with.
