Audix SCX25A condenser instrument microphone

Audix SCX-25A condenser microphone

The Audix SCX-25A is our engineers’ favourite microphone for mic’ing acoustic pianos and other acoustic instruments. The flat profile of the SCX-25A and the ingenious piano-mounting system (Audix SCX-25A-PS) allow a grand piano to be mic’ed up even with the lid closed and the clarity is unsurpassed.

The Audix SCX25A is a professional studio condenser microphone with an elegant design and a patented capsule suspension system. Uniquely shockmounted within an intricate machined brass ring, the Audix SCX25A capsule is completely isolated from the mic body and electronics. By successfully minimizing acoustic reflections and diffractions, the Audix SCX25A delivers a pure, open-air sound with exceptional detail and realism.

With a smooth uniform frequency response from 20 Hz – 20 kHz, the Audix SCX25A is very consistent when responding to on and off-axis signals, exhibiting excellent phase coherence and minimal proximity effect. The Audix SCX25A is characterized with a wide cardioid polar pattern which enables the sound engineer the opportunity to blend the sound of the instrument or vocal with the sound of the room. Other features include a one-inch (25 mm) gold vapor capsule, miniaturized electronics, and an extremely small footprint. The Audix SCX25A will handle sound pressure levels in excess of 135 dB and will provide up to 20 dB of ambient noise rejection.

In addition to vocals, the Audix SCX25A is ideally suited to capture acoustic instruments such as piano, guitar, vibes, woodwinds, brass, percussion toys, drum overheads, orchestra and symphony sectionals.

The Audix SCX25A, which is manufactured to exacting standards and tight tolerances, features a precision machined brass body, innovative capsule suspension system, steel mesh grill, black e-coat finish, laser etched model and serial number, Switchcraft XLR connector, and heavy duty nylon clip.
