General Characteristics
This microphone has a 22mm capsule with a 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 experimenta-
tion with placement and isolation requirements with the gain initially set
low to avoid equipment (and ear) damage. It is strongly advised to use a
mesh pop-filter to avoid moisture from damaging the capsule.
Contents
Unpack your MXL 990 microphone carefully and verify that all of the
following items are included:
•MXL 990 microphone
•Shock mount
•Carrying case
•Hard mount mic stand adapter
If any of these items are missing or damaged, contact the company from
which you purchased the microphone.
Power Requirement
The MXL 990 requires 48V phantom power (± 4V). If no sound is picked up
by the microphone, make sure that the phantom power on your mixer or
separate power supply is switched on.
Microphone Cable
The microphone cable can have a profound effect on the sound of
any microphone. Even the finest microphone will sound poor if the
interconnect cable allows noise to enter or causes distortion and loss of
information. We recommend that you use the best microphone cable that
your budget will allow.
Care
Dust and foreign material can reduce the performance of a microphone
over time, so you should store the MXL 990 in its case when not in use.

Shock Mount
The MXL shock mount can shift in shipment. Simply shift the nylon bands
to center the microphone in the assembly. Be sure that the wire clamp
does not rest on the chassis of the mount, as this impairs mechanical
isolation. Slide the mount all the way to the rim of the microphone for the
most secure hold.
