TM-ST1 is a stereo microphone with stereo pattern switching. The recordist can select between 90 and 120 degree pickup to capture more ambience or to reduce background noise. The mid-side design captures a wide stereo field while maintaining a solid center image. TM-ST1 uses a back-electret condenser design for crisply detailed audio with a long battery life for portable recording. The output cable terminates to a 3.5mm stereo jack, ideal for plugging into a DR-1 recorder.
