With its pre-amplified, pin hole style design and internal limiter circuit, this microphone effectively captures sound in various environments while minimizing background noise, making it ideal for professional applications.
ETS SM1-PH Microphone Features
- Omni-directional Pickup Pattern: 25’ pickup pattern ensures that sound is captured from all directions, providing flexibility in placement.
- Low Noise MOSFET Pre-Amplifier: Enhances audio quality by reducing noise levels, delivering clear sound reproduction.
- Wide Frequency Response: 500Hz-13kHz frequency range captures a broad spectrum of sounds, suitable for various audio applications.
- Hi-Cut/Low-Cut Filters: Switch selectable filters limit frequency response to 900-6kHz, significantly reducing unwanted background noise.
- Selectable Volume Range: Choose between “Line level” (0dB) or “Microphone level” (-30dB) to suit different recording needs.
- Adjustable Gain: Allows fine-tuning of the microphone’s output in both volume ranges for optimal performance.
- 100 Ohm Unbalanced Output: Compatible with a variety of audio equipment, providing easy integration into existing setups.
- Internal Peak Limiter Circuit: Responds in 0.5 seconds to prevent distortion from loud sounds, ensuring clean audio capture.
- 3 Position Euro-Style Connector: Facilitates fast and clean cable termination, simplifying setup.
- Reverse Polarity Protection: Safeguards the microphone from damage due to incorrect power supply connections.
- Power Requirements: Operates on 12 to 24VDC @ 10mA, making it energy-efficient.
- On-Board Voltage Regulator: Provides stable operation and RFI filtering for improved performance.
- High Signal-to-Noise Ratio: More than 60dB ensures clear audio with minimal interference.
- Sensitivity: -45dB sensitivity captures even quiet sounds effectively.
