The SM1-T is a high performance, omni-directional microphone designed to sit on a table top. Built in limiter circuit automatically lowers the output level during loud sound intervals. Built in weight and 4 rubber feet help minimize unwanted movement of the microphone. Black ABS enclosure sits on any surface.

Features:

• Omni-directional 25' pickup pattern
• Low noise MOSFET pre-amplifier.
• 500Hz-13Khz 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)
• 100 Ohm unbalanced output.
• 3 position terminal block.
• Power: 12 to 24VDC @ 10mA.
• PTTC fused and reverse polarity protected
• On-board voltage regulator and RFI filtering.
• Temperature range: -40 to 85C
• S/N ratio: more than 60DB
• Sensitivity –45DB
• Weighted black ABS enclosure with rubber pads stays put on any surface.
• Dimensions: L 3.7” W 2.6” H 1.4”
• Weight 0.21lbs

Includes:

 

• Warning label.
