SPECIFICATIONS:
ARCHITECTS AND ENGINEERS SPECIFICATIONS:
The microphone shall be of the condenser type with a modular threaded capsule available in
cardioid, hypercardioid, and supercardioid polar patterns. The microphone shall be protected from RF
interference. The microphone shall have a fully integrated preamp circuitry thereby eliminating the need
for a remote preamplifier module. The microphone shall operate on 18-52 Volts DC and the nominal
output impedance shall be equal to 150 ohms at 1 kHz. The microphone shall have a sensitivity of 37
mV / Pa at 1 kHz. The microphone shall have a maximum SPL level of ≥130 dB with THD of 0.5%. The
microphone shall be machined out of brass and the dimensions shall be 12 mm in diameter by 54 mm
in length. The microphone shall be the Audix M40.
OPERATION:
The M40 is a low impedance microphone and should be plugged into a “mic level” input on your console,
mixer, or recording device. The M40 requires phantom power and will NOT operate without phantom
power voltage (18-52 Volts) which is available on most professional mic preamps and mixing devices.
If phantom power is not available on your equipment, you will have to procure a phantom power supply
(such as the Audix APS2). Avoid plugging or unplugging the microphone into or out of the audio system
unless the channel is muted or the volume of the system turned down. Failure to do so may result in a
loud “popping” noise which could seriously damage the speakers in the sound system.
