Thank you for purchasing the MXL 992 Condenser microphone. With proper care, this mic will provide

many years of satisfaction. For best results, please take a few moments to review this literature.

General Characteristics

This microphone has a twenty-five millimetre gold-sputtered diaphragm and a fixed cardioid pickup pattern.
Condenser microphones are very sensitive, readily revealing very subtle sonic details. They also tend to
pick up sounds outside the pattern more than some designs, which can lead to powerful feedback if you are
not careful. We strongly advise experimentation with placement and isolation requirements with the gain
initially set low to avoid equipment (and ear) damaging surprises!

Power Requirements

IMPORTANT - This unit requires phantom power at 48 volts, +/- 4 volts. Each unit has been thoroughly
checked before shipping, so if you hear no sound, check that the phantom power on your mixer or separate
power supply is switched on!

Microphone Cables

The microphone cable can have a profound effect on the sound of any microphone. Even the finest
microphones will sound poor if the interconnect cable allows noise to enter, or causes distortion and loss of
information. Use only the best microphone cable your budget will allow.

Care

Dust and foreign material can degrade the performance of a microphone over time so always store the unit
in its case. Remove fingerprints from the exterior with a damp soft cloth. Clean the gold contacts
occasionally with a de-oxidant/cleaner. For vocals use a “popper stopper” or a foam windscreen to avoid
getting moisture on the diaphragm as this can substantially degrade the microphone’s performance.
