Dats V3 Dayton Audio Test System - Available for Pre-Order Now!


  • Dats V3 Dayton Audio Test System - Available for Pre-Order Now!

    An essential tool for speaker designers and audio engineers.

    When designing speakers, accurate parameters are a requirement for great success. After a decade of widespread use, The Dayton Audio Test System (DATS) has now acquired an impressive reputation for fast and accurate testing in the world of loudspeaker design and production. Wide user praise is revealed in the 91 user reviews of DATS V2 at the Parts Express web site with an average of 4.6 / 5.0 stars.

    Users loved DATS V2 and now V3 is evenbetter. The newest generation of the test system is housed in an aluminum enclosure with both the test leads and USB cable being detachable/replaceable. The calibration resistor (0.1% accuracy) is now integrated into the V3 front panel with convenient turret terminals for connecting the test leads. No more searching for or fiddling with a separate calibration resistor. This helps assure that your system is always accurately calibrated even for those “quick look” measurements.
    Here are some of the changes for DATS V3:
    • Rugged metal enclosure
    • Detachable test leads and USB cable
    • Double the test signal output level
    • The DATS linearity test
    • Integrated front panel calibration resistor (0.1%)
    • Tightened tolerances on internal components
    • Ongoing software improvements
    DATS V3 is a Windows PC hardware/software package that gives speaker designers the ability to take accurate impedance response measurements quickly and easily. For raw drivers, DATS V3 can derive the Thiele- Small parameters in a matter of seconds. In addition, the impedance response graph can allow you to identify unwanted resonances and other anomalies that might be causing issues.

    A new feature for DATS V3 is the linearity test. With the increased output capability, DATS V3 can begin to see changes in parameters with drive level. This new test automatically performs multiple sweeps of the driver at increasing (or decreasing) levels while saving each test result to memory. After the data is collected you can compare the results by recalling and comparing impedance plots and parameters.

    For finished speaker systems, the impedance response measurement allows you to compare the actual impedance response to the predicted impedance. This comparison makes it easy to see if the crossover and enclosure are performing as expected. Impedance comparison measurements can also be used to compare similar systems to detect component failures.

    DATS V3 also accurately measures the value of resistors, inductors (inductance and DC resistance simultaneously), and capacitors (capacitance, ESR, DF, Q, and loss angle measured at three different frequencies with one click).

    Other features make DATS V3 more than just a parameter measurement system. The Rub and Buzz test allows quick comparisons of many drivers to a reference standard to identify possible defects quickly and effortlessly. Just set the Fs/impedance tolerances (or accept the defaults), measure the reference driver and then DATS V3 will be ready to compare other drivers in an instant by displaying “Pass” or “Fail” along with the amount of deviation, all while being ready to measure the next driver. Each subsequent driver and parameters are saved into memories for review.

    DATS V3 also functions as a low-distortion signal generator. In addition to sine waves, the generator can also generate square, triangle, saw tooth and impulse waveforms as well as pink noise and white noise. DATS V3 also includes an oscilloscope to monitor the output signal. You can see the audio waveform with amplitude on the vertical scale versus time on the horizontal scale.

    Having all these capabilities just a click away is why DATS V3 will remain a must have tool for the speaker builder and a very valuable tool for anyone who regularly works with audio equipment.

      Every loudspeaker designer should be familiar with Thiele/Small parameters1, usually abbreviated T/S. Originally defined in the 1960s, they are a simple model of how transducers behave – mostly useful for designing ported cabinets like subwoofers. In 1971 they were brought to the attention of the US audio world by A. Neville Thiele, a native Australian, and Richard H. Small, a San Diego native who moved “down
      under” to work with Thiele. This...

      The first electronic loudspeaker designs were introduced in the 1920s, and while there have been many improvements in component materials over the decades, not much has changed in the basic functionality of a loudspeaker: a permanent magnet interacts with an electromagnet (voice coil) to move a cone back and forth, which produces sound waves. Founded in 1966, Eminence has been a leading
      supplier of loudspeakers for professional audio, musical instrument, car audio,...
