ETS SM1-U Unidirectional Microphone W/ Ambient Noise Rejection & 12VDC Power
The ETS SM1-U is a uni-directional microphone for use where background noise must be reduced. You simply mount
the SM1-U in the direction of interest and the ambient noise around will be seriously dampened while it brings out the audio of the targeted area.
Additional features of this audio mic include a selectable on/off treble circuit, easy cable termination, and low noise pre-amplifiers. Furthermore the SM1-U mic is powered through basic 12VDC, which makes it extremely useful in a number of audio surveillance applications.
