The Audix M40 is a miniaturized condenser microphone with a fully integrated preamp designed with very high sensitivity for distance miking.

The primary applications for the ceiling mounted M40 include Video & Teleconferencing (VTC), distance learning, hospital rooms, surveillance and ambient room miking.The M40 has complete immunity from RF interference caused by cell phones and GSM devices.

The M40, which comes with a cardioid capsule, is also available with hypercardioid or shotgun capsules, allowing for the microphone to be used in a wide variety of applications.The M40 is easy to install requiring only that a 5/8 inch hole be drilled in the ceiling with no additional tools required.

The cable assembly is equipped with a terminal block connector.

For installations where plenum rated cable is to be used a UL rated, metal plenum junction box is available.Optimized for voice recognitionImmunity from RF interferencePoint to shoot directivityIntegrated preamp circuitry12 mm gold vapordiaphragmExtremely low noise, high sensitivityDesigned, assembled andtested in the USAAudix M40W6S Features:Optimized for voice recognitionImmunity from RF interferencePoint to shoot directivityIntegrated preamp circuitry12 mm gold vapordiaphragmExtremely low noise, high sensitivityDesigned, assembled andtested in the USAAudix M40W6S Specifications:Transducer Type: CondenserFrequency Response: 60 Hz - 10 kHzPolar Pattern: Cardioid / Hypercardioid /SupercardioidOutput Impedance: 150 ohmsSensitivity: 37 mV / Pa @ 1kEquivalent Noise Level: 22 dB (A-weighted)Signal to Noise Ratio: 72 dBMaximum SPL: >=130 dBDynamic Range: 108 dBPower Requirements: 18-52 V phantomConnector: 3-pin terminal blockPolarity: Positive pressure on diaphragm producespositive voltage on pin 2 relative to pin 3 of output XLR connectorMaterials / Finish: Aluminum & Zinc Alloy / Whiteor Black FinishWeight: 12.9 oz (75 g)Length: 6.5" (165 mm)
