Description
The SM1-PH is a pre-amplified, pin hole style, omni-directional, microphone. Internal Limiter circuit lowers the output level during loud sound intervals.
Features
- Omni-directional 25’ pickup pattern
- Low noise MOSFET pre-amplifier
- 500Hz-13Khz Frequency response
- Switch selectable hi-cut/low-cut filters limit frequency response to 900-6khz significantly reducing background noise
- Switch selectable volume range: “Line level” (0db) or “Microphone level” (-30db)
- Adjustable gain in both volume ranges
- 100 Ohm unbalanced output
- Internal peak limiter circuit (.5 sec response)
- 3 position Euro-style connector makes cable termination fast and clean
- Reverse polarity protected
- Power: 12 to 24VDC @ 10mA
- On-board voltage regulator and RFI filtering
- S/N ratio: more than 60DB
- Sensitivity –45DB
