Improved RFI and EMI suppression Undamped, screen damped, and internally damped responses Numerous port locations Custom tube diameters and lengths available Custom corner frequencies achieved through an electrical high pass filter optimizes noise performance at low frequencies for demanding matching and directional applications BTO offers improved Power Feedthrough Attenuation, improved settling time, and an electrical high pass filter

The TO is the thinnest omni-directional microphone offered. Its small size is perfect for all applications, especially where space is an issue. The TO can also be used in directional applications as either a matched omni-directional pair, or in the TP series uni-directional / omni-directional pair. The BTO is an improved version of the TO microphone. It offers enhanced PFA performance, as well as power-on reset and an electrical high pass filter. The BTO is ideal in directional applications as a matched omni-directional pair.
