CM311 AESH

CM311 L

esigned for touring and live-sound

applications, the AKG/Crown CM311

is a rugged head-worn microphone

with unequalled performance. It sounds like

the best handheld microphones - full,

clear, and distortion-free, even with the

loudest singers.

The CM311 is the latest version of the

AKG/Crown’s proprietary Differoid

technology. Its cardioid pickup pattern

rejects sounds from the rear, such as floor

monitors. Its

noise-cancelling ability rejects

sounds at a

distance, such as instruments

on stage and

crowd noise. This results in

the CM311 having outstanding gain-before-

feedback and isolation.

Lightweight and comfortable, the mic’s

headband and boom adjust to fit any singer.

An included pop filter greatly reduces

breath noise and pops. Because of the

boom’s unique behind-the-ear design, it

does not cover up the singer’s face.

Three models are available: CM311 A,

CM311

AESH and CM311 L. The CM311 A is

9 V battery or phantom power.

It has a

battery belt pack with an on/off

switch, a

programmable mic on/off switch,

and a

“Mic On” LED. The CM311 AESH has

a T4AF connector, allowing you to connect with

Shure® wireless systems. The L version offers a

3-pin mini XLR output, which fits all AKG wireless

body-pack transmitters.

How to adjust for best fit and to prevent

boom bounce

Note: To get the maximum performance out

of this microphone, take the time to adjust it

to fit correctly.

For best results, the CM311 A MUST be

custom fitted to a single user’s head. This

simple procedure takes only a few minutes.

Please refer to Fig. 5 and locate the parts

described.

1. If the microphone is for yourself, we

suggest that you use a mirror to double

check the fit as you make adjustments.

2. Loosen (just a little) the thumbscrew

located on the outside of the foam block,

part way back on the boom. This allows the

boom to slide in and out, and to rotate left

and right.
