Condenser Cardioid hanging choir mic, black 

The ADX-40 is a miniature pre-polarized condenser microphone designed to hang from an overhead position for applications in professional live sound, music, and broadcast. Available with a choice of three optional interchangeable microphone capsules (cardioid, omni, and hypercardioid), the ADX-40 is most commonly used for plays, theatrical productions, choirs, group vocals, and room ambience miking. With a smooth uniform response over a frequency range of 40-20k Hz, the ADX-40 provides a warm, rich sound not typical of microphones this size. It is machined from solid brass and comes in a non-reflective black finish. Supplied with an attached 30' cable, the ADX-40 operates on phantom power (9-52volts) with the preamp module provided (APS-910). If phantom power is not available, there is an optional power supply (APS-911) that operates in phantom or battery mode with bass roll-off and on-off switches. Low noise electronic circuitry, low impedance, and balanced output allow interference-free performance even with long cable runs.
