High performance, Unidirectional pre-amplified microphone for use where side noise must be reduced. Simply mount the SM1-ULE2 in the direction of interest. Built in limiter circuit automatically lowers the output level during loud sound intervals. Selectable lo-cut and hi-cut filters significantly reduce background noise. ABS enclosure Mounts on any flat surface.

Features:

• Uni-directional 25' pickup pattern with reduced (-6db) sensitivity on all sides.
• Low noise MOSFET pre-amplifier.
• S/N ratio: more than 60DB
• Sensitivity –45DB
• 500Hz-16Khz Frequency response.
• Switch selectable hi-cut/lo-cut filters limit frequency response to up to 900 to 6Khz significantly reducing background noise.
• Switch selectable volume range: "Line level" (0db) or "Microphone level" (-30db)
• Adjustable gain in both volume ranges.
• Internal peak limiter circuit (.5 sec response)
