TM Series Microphones
The TM provides the best combination of performance and size. It boasts performance comparable to the standard EM series, in a package 20% smaller. The TM can also be used in directional applications as a matched omni-directional pair. The BTM is an improved version of the TM microphone. It offers enhanced PFA performance, as well as power-on reset and an electrical high pass filter. The BTM is ideal in directional applications as a matched omni-directional pair.
Features
- Rugged construction to withstand severe environmental conditions
- High resistance to mechanical shock
- Improved RFI and EMI suppression
- Undamped, screen damped, and internally damped responses
- Numerous port locations and a wide range of frequency responses available
- Extended housing TM microphones also available improving sensitivity/noise in the same footprint
- Custom corner frequencies achieved through an electrical high pass filter optimize noise performance at low frequencies for demanding matching and directional applications
- BTM offers improved Power Feedthrough Attenuation, improved settling time, and an electrical high pass filter
