Audix ADX51 — Professional Cardioid Condenser Microphone with Pad and Roll-Off
ADX51 Overview
The Audix ADX51 is a professional pre-polarized condenser microphone built for stage, studio, and broadcast applications, offering clear and accurate acoustic reproduction across a wide range of instruments. Its uniformly controlled cardioid polar pattern is engineered to capture the source instrument while rejecting off-axis bleed from surrounding sources on stage or in the studio. The 14 mm gold vapor diaphragm delivers a wide frequency response of 40 Hz to 18 kHz, while the onboard -10 dB pad and 150 Hz bass roll-off filter provide the flexibility needed for both close and distance miking scenarios. The ADX51 is well suited for audio engineers, system integrators, houses of worship, and broadcast facilities requiring consistent, reliable condenser performance.
Designed, assembled, and tested by Audix in the USA, the ADX51 is built to tight manufacturing tolerances with a precision machined brass body, durable black E-coat finish, steel mesh grill, and gold plated XLR connector for long-term reliability in demanding environments.
Key Features
- Pre-Polarized Condenser Capsule — 14 mm gold vapor diaphragm provides accurate, detailed acoustic reproduction without requiring an external polarizing voltage
- Uniformly Controlled Cardioid Polar Pattern — Captures the target source while isolating it from adjacent instruments, reducing stage bleed and improving mix clarity
- Wide Frequency Response — 40 Hz to 18 kHz range accommodates a broad variety of acoustic instruments in both close and distance miking applications
- -10 dB Pad — Allows the ADX51 to handle higher sound pressure levels without distortion, extending its usability to louder acoustic sources
- 150 Hz Bass Roll-Off Filter — Reduces low-frequency buildup and proximity effect, keeping the low end clean in live and studio environments
- Precision Machined Brass Body — Manufactured to high tolerances with a durable black E-coat finish and steel mesh grill for consistent performance and physical durability
- Gold Plated XLR Connector — Ensures reliable signal transfer and corrosion resistance over extended use
- USA Designed, Assembled, and Tested — Built by Audix in the USA to professional standards for stage, studio, and broadcast deployment
