MXL 770X User Guide

Selectable Polar Patterns

The polar pattern of the microphone indicates how the microphone has been designed to react to
incoming sound waves. The 770X has the ability to switch between polar patterns to best match the
recording environment.

The Cardioid polar pattern excels at picking up sound from the
front of the microphone, less from the sides and has good rejection
of sounds to the back of the microphone. Select the cardioid pattern
for situations when you want to pick up specifi c sound sources, such
as a specifi c guitar within an ensemble, and is recommended for
recording applications where the acoustics are good, but not perfect.
For instance, a cardioid pattern is less likely to pick up ambient noise
from computers and recording equipment.

Cardioid

The Omni-Directional polar pattern picks up sound equally
from all sides of the microphone. This is best used for recording in
environments with excellent acoustics, as the omni-directional pickup
excels at picking up ambient noise. The omni-directional polar pattern
is less sensitive to “plosives”, handling noise and the proximity effect.

Omni

770X

The Figure-8 polar pattern will pick up sounds from the front
and back of the microphone with equal sensitivity while maintaining
a large amound of rejection 90 degrees off axis. Figure-8 patterns are
the most susceptible to proximity effect and are commonly used in
Mid-Side (MS) stereo recording setups.

General Characteristics

This microphone has a dual-diaphragm 32mm capsule that provides multiple pickup patterns and
a very open and detailed sound. Large capsule condensers 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, in order to operate. 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!

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.
