About This Product
■ Advantages to use TEDS microfones
The TEDS microphone has a cartridge's individual identification information and load sensitivity in TEDS, and the biggest advantage is that when connected to the measuring device, this information is automatically set. The mini CD attached to many TEDS microphones contains individual characteristic data, and can be used to correct frequency characteristics. In addition, cartridge and preamplifier are sealed as a unit in a clean room to avoid incorporation of impurities such as chili, which causes aging of performance.
All TEDS Microhons, excluding TEDS template 4957 and 4958, are provided in a template that meets IEEE 1454.4 V0.9. If you specify it at the time of purchase, you can provide IEEE 1545.4 V1.0 template free of charge.
■ Data transmission
In general, there are two ways to transfer data from TEDS chip to analyzer. The simple method is to use a dedicated line for data transfer called class 2. In the conventional LEMO type TEDS preamplifier, 5 output terminals are transferred to TEDS data.
On the other hand, the method of class 1 is a single -track system such as DeltaTron, and signals and data transfer are performed at the same line. In this case, it is possible to use a single track by changing the mode (TEDS data/signal) electrically.
■ Custom -made TEDS Microphone
You can also provide a custom -made microphone. If you can not find any specifications, please contact us.
■ Diffusion sound field TEDS Micro Hon
The diffused sound field type microfon is also called a random in -case -type micro -hon, and is designed to have flat properties in a random sound field or a diffusion sound field where sounds enter at the same time from all directions. In addition, it is used in a diffusion sound field where multiple sound sources contribute at the measurement point. This includes indoor measurements in which sounds are reflected depending on the walls, ceilings, and objects of the room.
Other main uses of the diffusion sound field type microfones are measurements in the car room or in the cabin.
