Something New! TEF Talk! We've expanded this feature to include a link to the NEW TEF TALK FORUM, where information, discussion and ideas about TEF can be found. This page is different from the TEF Tips page that is dedicated to fixes and work-arounds to various TEF problems. Click on TEF Talk in the Menu to the left and see what's up.

The TEF25 is a True Dual Channel Analyzer with accurate Phase Information, Balanced Inputs and Outputs, Phantom Power and a noise floor of -130dBV.
A new software option (SLPPS60), allows the user to store data and then POST PROCESS TDS measurements.
Noise Level Analysis (SLNLA60) is now available in Windows with new features and flexibility.
EZTune software is available for fast set up in small acoustical spaces. It includes automated routines for easy measurements of SPL, Reflections, Frequency Response, Optimal Filter settings for EQ and a Modal Calculator from our friends at McSquared Design Group.
The TEF25, along with your laptop computer and TEF Software, is all you need to make TEF measurements. It's easy to carry and can be powered directly from your USB computer port.
All TEF20 windows programs: MLS, PEQ, PET, PLR, RTA, SLX and TDS can now be run on the new TEF25 USB Preamplifier.

The TEF Analyzers are dedicated instruments designed to perform Time, Energy and Frequency (TEFŽ) measurements using the science of Time Delay Spectrometry (TDS).

The power of the TEF platform lies in its ability to join specialized software and the TEF25 or TEF20 analyzer with your computer to form a complete measurement system.

The TEF analyzers feature powerful processors with the speed and power to execute millions of instructions per second enabling it to accurately process complex acoustical data.

Sound contractors, consultants and engineers rely on TEF when they design, install and verify sound systems and solve problems associated with various aspects of room evaluation.

Optional software packages perform such functions as real time analysis, precision equalization, noise level analysis to name a few.

An invaluable tool, TEF analyzers enable the sound professional to see and measure existing acoustical problems while evaluating each change as it is made. When it comes to system design, verification and validation, nothing comes close to a TEF.

A TEF20 - USB adapter is now available. Go to the TEF Accessory page for more information.

The Original Sound Lab TDS Manual for DOS is available for download. Go to the TEF Tips page.

TEF and INTELLIGIBILITY - The TEF20 analyzer was put through it's paces at an Intelligibility Workshop. Download the article. 419K. This article is provided through the courtesy of Syn-Aud-Con.

Pentium Users! Software upgrades are available. If you have a Pentium Class Computer or are thinking of going to a Pentium Class Computer, your software can be updated! Contact Us.

Be sure to visit our TEF accessory page. We have added new items that compliment the TEF measurement system.
