- Supports identification of IEEE P1451.4 transducers (TEDS)
- Supports Charge Injection Calibration tests
- Robust construction
- Stackable
- Powers up to 4 microphone channels simultaneously
- Enables the functionality of the microphones and preamplifiers to be checked using CIC and TEDS

Note that Brüel & Kjær Preamplifiers Types 2669, 2670 and 2671 are all delivered with the TEDS capability. There are over 40 microphone/preamplifier combinations available as calibrated units where the combined sensitivity is already written into TEDS.
Applications include the production, testing and quality control of loudspeakers and telephones. The elegant design enables several Type 2829 units to be stacked on top of one another, if necessary.
If the connected microphone/preamplifier combinations contain TEDS (Transducer Electronic Data Sheets), they can be interrogated by connecting a TEDS Editor via the four pole RJ 11 socket labelled IEEE 1451.4. Type 2829 can supply both 0 V and 200 V polarization voltage for the microphones.
