Audio-Technica AT4021 Cardioid Condenser Instrument Microphone

The Audio-Technica AT4021 Cardioid Condenser Instrument Microphone is a low-profile, end-address microphone engineered for critical studio and live applications. It provides a flat, extended frequency response and a wide dynamic range to ensure accurate sound reproduction across various environments.

High-Performance Audio Engineering

The AT4021 utilizes a low-mass diaphragm that enhances transient response and increases response bandwidth. This design reduces mechanical noise transfer and handling noise, allowing for cleaner audio capture. The microphone offers exceptional reproduction of low-frequency sounds, making it suitable for capturing instruments with deep tonal characteristics.

Signal Management and Isolation

The cardioid polar pattern delivers a high front-to-back rejection ratio, which improves the isolation of the intended sound source. This pattern effectively minimizes unwanted noise from the sides and rear. To accommodate loud sound sources, the microphone handles high maximum SPL without sacrificing clarity.

Integrated Controls

The AT4021 includes built-in controls for precise signal management:

• 80 Hz High-Pass Filter: A switchable filter helps eliminate low-frequency ambient noise.
• 10 dB Pad: A switchable attenuator prevents distortion when capturing high-volume sound sources.

Durable Construction and Low Noise

Built with a rugged design, this microphone maintains reliability in both stage and studio settings. The low self-noise performance ensures compatibility with sophisticated digital recording equipment, maintaining signal integrity throughout the recording process.
