Dimensions (mm)
3.61 x 3.61 x 1.30
Intro
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
• Un-damped, 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
