Specialty Microphones and Alternatives Summary

Specialty Microphones Overview

Boundary/Plate Microphone

• Also known as PZM (Pressure Zone Microphone).

• Captures sound using a small element near a flat surface.

• Suitable for conferences and stage productions.

Lavalier Microphone

• Miniature, clip-on mic for broadcasting.

• Commonly used hands-free in presentations and theater.

• Available in omnidirectional or cardioid patterns.

Shotgun Microphone

• Highly directional with a narrow pickup pattern.

• Used in film/TV to focus on specific sound sources.

• Enhanced directionality via interference tubes.

Parabolic Microphone

• Uses a dish-shaped reflector for long-range audio capture.

• Often employed in nature recording and surveillance.

Ambisonic Microphone

• Captures immersive 360-degree sound.

• Ideal for VR/AR applications, uses multiple capsules.

Contact Microphone

• Captures vibrations directly from solid surfaces.

• Suitable for instruments and unique sound exploration.

Measurement Microphone

• Omni condenser for acoustic measurements.

• Used in live sound, scientific research, and audio analysis.

Drum Triggers

• Attach to drum heads to capture vibrations.

• Output audio for live/studio use.

Alternatives to Microphones

Direct Injection Box (DI Box)

• Converts unbalanced, high-impedance signals to balanced low-impedance signals.

• Used for instruments with unbalanced outputs to minimize noise.

Types of DI Boxes

• Passive: Uses transformers, requires no power.

• Active: Requires power, offers higher headroom and sound quality.

Re-ampers

• Convert balanced line-level signals to instrument-level outputs.

• Enables creative sound options through amplifiers and effects.

Guitar DI Options

• Reactive DI captures amp signal and speaker's back impulse for realism.

• Amp modeling integrates amp and cabinet modelling with DI outputs.
