ETS SM1-PH Pin Hole Omni-directional Microphone

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 ensures clear audio capture from all directions, making it ideal for diverse recording environments.
• Low noise MOSFET pre-amplifier: Enhances audio quality by reducing unwanted noise, resulting in clearer sound production.
• Wide Frequency response: 500Hz-13KHz ensures a broad range of sound reproduction for professional audio applications.
• Switch selectable hi-cut/low-cut filters: Limits frequency response to 900-6kHz to significantly reduce background noise, improving overall audio clarity.
• Volume range options: "Line level" (0dB) or "Microphone level" (-30dB) allows for versatile use depending on the specific recording needs.
• Adjustable gain: Available in both volume ranges, providing flexibility in sound reinforcement based on the recording environment.
• 100 Ohm unbalanced output: Ensures compatibility with a range of audio equipment while maintaining high audio quality.
• Internal peak limiter circuit: Responds in just 0.5 seconds to prevent distortion from sudden loud sounds, safeguarding audio integrity.
• 3 position Euro-style connector: Makes cable termination fast and clean, streamlining setup and reducing installation time.
• Reverse polarity protection: Increases reliability by safeguarding the microphone from damage due to incorrect power supply connections.
• Power requirements: Operates on 12 to 24VDC @ 10mA, making it energy-efficient and easy to integrate into various setups.
• On-board voltage regulator and RFI filtering: Enhances performance by ensuring stable operation and reducing interference from other signals.
• S/N ratio: More than 60dB ensures superior sound quality and clarity, ideal for professional applications.
• Sensitivity: -45dB provides a strong audio signal for clearer sound capture, suitable for a range of settings.
