Highest performance, Omni-directional, pre-amplified microphone for fixed location security applications. Ideally suited for interrogation and interview rooms.

Features:

• Ultra low noise / high sensitivity
• Adjustable high and low frequency cut off filters. Useful for reducing back ground noise.
• Adjustable automatic level control with a compression ratio range of1:1 to 10:1. The circuit automatically lowers the gain in loud environments and when quiet, raises the gain where faint audio sources such as people whispering can be heard.
• Universal Power input: Accepts 12-60VDC or 9-42VAC
• Omni-directional 25' pickup pattern
• Low noise MOSFET pre-amplifier.
• 80db S/N ratio, -28db sensitivity
• 500Hz-16Khz Frequency response (hi-cut and lo-cut off) -40C to 105C.
• Industrial temperature range:
• Flexible plastic plate mounts flush or on a single gang electrical box.
• On-board voltage regulators and RFI filtering.
• Power: 12-60VDC or 9-42VAC @15mA.
• 3 position Euro-style connector makes cable termination fast and clean.
• Treble boost pre-emphasis.
• 100 Ohm unbalanced output.
• Adjustable output level (post AGC).
• Adjustable automatic gain control. (compression range 1:1-10:1).
• Adjustable lo-cut filter: (500hz to 1Khz)
• Adjustable hi-cut filter: (5Khz to16Kz)
• Dimensions: L 4.7” x W 2.9” H 0.9”
• Weight .1lbs
• Available in most other SM1 form factors.
