Features Verifies System performance before major events. Monitors multiple zones with 5 MUX microphone inputs. An independent input is provided for special measurements such as a Type 1 NLA measurement. Provides Pass/Fail evaluation in accord with predetermined criteria. Software to add Distortion Criteria to Pass/Fail TDS test. Sound Lab RTA measurements for customer use. Requires a dedicated computer with internet connection (not supplied). Rack Mounted.

For many years, leading acoustic consultants have utilized TEF to accomplish outstanding acoustic designs. Consultants, traveling with TEF, are credited with designing many of the best Halls, Public Buildings, Terminals and outstanding Churches. The superior work of this select group of talented consultants is naturally in much demand. Limited available time and distances make it difficult to satisfy even the best customers. An installed TEFnet System helps to overcome Time and Distance constraints and allows consultants to be more available.

TEFnet is a complete TEF25 analyzer with 5 MUX inputs plus an additional input for special applications. The system is utilized in conjunction with a dedicated house computer. The consultant installs microphones in selected locations and sets the parameters for Pass/Fail evaluation. The software will prevent any unauthorized change made to the consultant's specifications. The Pass/Fail evaluation is based on a TDS test sweep and automatic sequential activation of MUX microphones. The Pass/Fail evaluation Test utilizes modified Sound Lab speaker test software.

The accuracy and usefulness of the Pass/Fail evaluation is based on the parameters selected by the Consultant and his ability to specify the acceptable tolerances for measurements at each of the microphone locations. Only the Consultant will specify the Pass/Fail parameters. The Pass/Fail software allows the customer to rapidly check his system before major events.

The Resident Soundmen will not be authorized to change the Consultants Pass/Fail parameters, however they will be able to measure frequency and SPL plus take advantage of the multiple microphones installed in many locations.

Other software such as NLA, can be added to document noise levels during a performance. Any other Sound Lab module can be added to the system to fill special needs.

Data from the Pass/Fail test will be accumulated on the dedicated house computer and made available via the Internet to authorized users or reported to the Consultant. Standard Windows software exists to allow the Consultant to access and control the TEF from a remote location. The Consultant will be able to look at all MUX positions or any individual position and make use of other TEF Sound Lab modules if they are included as part of the system. MUX measurements are individual but can be combined in the RTA software.
