How should I position the A3 for best coverage?

Choosing the right position depends on the microphone pickup pattern and subject

position. The A3 Podium Microphone is available with precision omnidirectional, cardioid, or

hypercardioid patterns, or in a selectable pattern version allowing the microphone to switch

patterns instantly. In all cases, the ideal distance from microphone to subject is about 12

inches (30 cm), positioned at chest level, pointing toward the face.This location eliminates

pops and other breath noises, doesn’t interfere with sight lines, and accommodates both

normal conversational levels and presenters who prefer to project to the crowd.

A3 Podium: Frequently Asked Questions

How should I mount the A3 to a desk or podium?

The Countryman A4CDM Desk Mount consists of a Neutrik connector module and a metal

bushing that can be mounted through a table top or podium surface. It both supports and

connects the mic, and provides an attractive, unobtrusive mount with a very small footprint.

This kind of mounting is practical only because of the A3’s Active Vibration Plus shock

isolation—other podium microphones require bulky shock mounts to avoid table vibration

noises.

Mounting the A4CDM requires drilling the table surface and soldering to the connector

module, and is recommended for permanent installations only. The mic itself is held in place

by the XLR connector’s latch and can be removed easily for storage.

Hypercardioid

The A3 Podium’s extremely accurate hypercardioid pattern picks up approximately a

90° cone extending from the tip of the microphone, allowing the presenter to move

around or share the podium with a second person. This pattern also has the most

rejection of ambient noise and feedback and is the most popular ﬁxed pattern option.

Cardioid

The cardoid pattern has a pickup angle of about 130°, which is well-suited to groups

or moving subjects. This pattern has the most rejection to the rear of the microphone,

making it useful for taming feedback from nearby ﬂoor monitors.

Omnidirectional

The omnidirectional pattern picks up equally from all directions, making it ideal for a group

around a table or picking up the ambient sound of an ensemble or space. This pattern can’t

reject interfering sources and is not suitable for environments where feedback is an issue.

Selectable

Selectable pattern A3 Podium Microphones have a switch at the base allowing the

microphone to change instantly between any of the above patterns, making it the most

versatile choice.

XLR3 connection

1/8” pipe nipple or

“lamp pipe” bushing.

Can be any length;

one inch is normally

supplied for table

surfaces 3/4” or less

in thickness. Drill 7/16”
