Contents

Unpack your MXL microphone package carefully and verify that all of the following items are included:

• Rugged Carrying Case

• MXL H-03 Mic Stand Adapter

- MXL 990 Microphone

• MXL MT-001 Mic Stand Adapter

- MXL 991 Microphone

Power Requirements

IMPORTANT - The 990 requires 48V phantom power (± 4V).

IMPORTANT – The 991 requires phantom power at 48 volts, +/- 4 volts.

Each unit has been thoroughly checked before shipping, so if you do not hear sound, check that the phantom power on your mixer or separate power supply is switched on.

Microphone Cables

Your 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. We highly recommend the Mogami® brand microphone cables.

Care

Dust and foreign material can degrade the performance of a microphone over time, so always store the unit in its box. For vocals closer than 3", use a pop filter or a foam windscreen to avoid getting moisture on the diaphragm as this can substantially degrade the microphone's performance. Store the microphone in its original packaging in a cool, dry place along with the included packet of silica gel.
