Spec Sheet
Installation Instructions

When selecting a microphone for your application, it’s important to understand the performance differences between Default and Low Noise versions. Whether you’re using an omnidirectional mic for broad area coverage or a directional mic for focused pickup, choosing the right noise profile can greatly impact audio clarity.

🎤 Omnidirectional Microphones: Default vs. Low Noise

Omnidirectional mics capture sound equally from all directions, making them ideal for general-purpose use, surveillance, and open-area coverage.

Feature	Low Noise Omni Mic	Default Omni Mic
Sensitivity	-28 dB	-44 dB
Signal-to-Noise Ratio (SNR)	80 dB	60 dB
Ideal For	Clean, professional-grade audio	Basic installations

Key Differences

The Low Noise version is significantly more sensitive, meaning it picks up softer sounds without requiring high gain.
It also has a much higher SNR, producing clearer audio with less internal hiss or static.

✅ Choose the Low Noise Omni Mic if you’re using the mic in quiet spaces, need better clarity, or want stronger performance at lower gain settings.
❗ Choose the Default Omni Mic if you’re working in a noisy area or operating on a smaller budget where audio perfection is not critical, as the Ultra Low Noise option comes at a small upcharge per unit cost.

📡 Directional Microphones: Default vs. Low Noise

Directional (or uni-directional) mics focus on sound from one direction while minimizing ambient noise from the sides and rear. They’re great for kiosks, intercoms, and focused listening applications.

Feature	Low Noise Directional Mic	Default Directional Mic
Sensitivity	-35 dB	-54 dB
Signal-to-Noise Ratio (SNR)	70 dB	60 dB
Ideal For	Focused, high-clarity listening	Basic directional audio

Key Differences

The Low Noise Directional Mic is much more sensitive, capturing more detail with less gain.
It also produces less self-noise, which is important for environments where you need clear, focused audio.

✅ Choose the Low Noise Directional Mic if your application requires speech clarity, low background noise, or professional-grade sound.
❗ Choose the Default Directional Mic if you’re in a high-noise area or need a cost-effective directional solution.

🧠 Final Thought

Both microphone types perform reliably—but if audio clarity, lower background hiss, or gain efficiency are important in your setup, the Low Noise models offer a significant upgrade. They’re especially well-suited for surveillance systems, interview rooms, kiosk audio, and quiet environments where every detail counts.
