Quick Start for the WT3 Woofer Tester

*** VERY IMPORTANT SAFETY NOTE ***

NEVER connect the test leads of the WT3 to a speaker that is connected to any other equipment or to an equipment ground! Severe damage could occur to the WT3 unit or to the other equipment. Only connect the WT3 to an unconnected loudspeaker.

Naturally, you will want to test your first woofer as soon as you get your WT3. Here are step-by-step instructions to get you going quickly.

1) Install the WT3 software.

•Insert the WT3 CD and allow the file named "WT3_setup.exe" to auto-run. (Alternately you can double-click on the "WT3_setup.exe" file to start the installation

process.)

•Follow the on-screen instructions to complete the software installation

•Check for available upgrades at: http://www.daytonaudio.com/wt3updates.html

2)Connect the WT3 hardware unit to any convenient USB port on your computer.

After a few seconds the PC will recognize the new hardware. However, on initial power up the unit requires a full 90 seconds to stabilize before measurements can be made. After this initial plug-in delay, impedance measurements take only a few seconds to complete. This settling time is due to the extremely wide low frequency bandwidth required for high precision measurements down to 1 Hz.

3) Set the Windows Volume Controls to Maximum.

From the task bar, double-click on Volume Control to open the mixer and Raise both the "Master" and the "Wave" sliders to maximum. Make sure the Wave signal is panned to center. Although drivers can be tested at lower signal levels, WT3 was designed to normally be used with the Windows Volume control set at maximum.

4) Launch the WT3 application software.

From the Windows "Start" button select "All Programs" then select "WT3". The WT3 software will launch.

5) Connect the alligator clips from the WT3 unit to the 1k Ohm calibration resistor.

WT3 specifications

The Dayton WT3 is a sophisticated and highly regarded tool in the field of audio measurement and analysis, particularly known for its precision in loudspeaker testing. This comprehensive device integrates several advanced features and technologies, making it an essential choice for audio professionals, engineers, and hobbyists alike.

One of the standout characteristics of the Dayton WT3 is its dual-channel capability, allowing users to conduct simultaneous measurements of two different loudspeakers. This feature is particularly useful in stereo systems where matching drivers is essential. The WT3 utilizes a high-resolution analog-to-digital converter (ADC) that ensures accurate and detailed frequency response measurements, providing users with the data they need to refine and optimize their audio setups.

The WT3 is equipped with a user-friendly interface that simplifies the measurement process. Its software is intuitive and runs on Windows, which means that users can easily navigate through various options to configure tests and analyze results. The inclusion of a built-in microphone makes it possible to perform room acoustics measurements, further enhancing its versatility.

Another key technology integrated into the Dayton WT3 is its frequency sweep capability. By generating continuous sine wave sweeps across a wide frequency range, the WT3 can analyze the response of loudspeakers in real-time. This allows for identifying resonances, distortion, and other critical parameters that affect sound quality.

The WT3 also features a range of measurement modes, including impedance measurements, which can be invaluable for understanding how a loudspeaker behaves across different frequencies. This data is displayed in easy-to-read graphs and charts, facilitating a straightforward interpretation of results.

Moreover, the Dayton WT3 utilizes advanced signal processing algorithms that help in reducing noise and other unwanted artifacts that can skew measurements. The device's accurate phase response measurement capability further distinguishes it from competitors, providing essential data for crossover design and speaker alignment.

In summary, the Dayton WT3 combines advanced measurement technology with an intuitive user experience, making it an essential tool for those seeking precise loudspeaker performance insights. Its features and capabilities position it as a valuable asset for both professional audio engineers and enthusiasts dedicated to achieving the best possible sound quality. Whether for designing new speakers or optimizing existing setups, the WT3 delivers reliable performance and accuracy.
