Introduction

Thank you for your purchase of the NTG-3

precision broadcast-grade shotgun microphone.

The NTG-3 is one of ’s most exciting

microphones. It is the result of years of development

by engineers, providing the professional

broadcast and ﬁlm industries with an affordable yet

uncompromising microphone.

One of the key features of the NTG-3 is its ability to

withstand adverse conditions. Using a technology

known as RF bias the NTG-3 is almost completely

resistant to moisture, making it the only option when

recording in any demanding environments where

condensation is an issue.

In addition to its very low weight and anti-glare ﬁnish,

the NTG-3 also features incredibly low self-noise. I’m

conﬁdent that you won’t ﬁnd a similar microphone that

is this quiet.

When not in use you’ll be able to store the NTG-3

in the weather resistant aluminium anti-roll storage

cylinder (standard with purchase), providing additional

protection when traveling and storing the NTG-3.

Please take the time to visit www.rodemic.com and

While there you can view studio/ﬁeld tips and

techniques, as well as browse the comprehensive

range of accessories for the NTG-3 and other

microphones.

• Extremely low handling noise

• High level of immunity to

radio frequency interference

• High sensitivity

• Superior broadcast sound quality

• Designed & manufactured in Australia

• Full 10 year guarantee*

Powering the NTG-3

• The NTG-3 requires power to operate. This needs

to be supplied via a P48V phantom power supply

which is available from most professional video

cameras or mixing consoles.

• If the camera or console does not provide phantom

power, then an external phantom power supply is

needed.

*Online product registration required.

• We strongly suggest the use of high quality XLR

cables, using the shortest cable length possible

to ensure minimal noise interference between

the microphone output and the camera/recorder

input.

• The NTG-3 features a custom designed XLR

connector that is specially designed to reduce

susceptibility to RF interference from devices such

as cell phones.

• When mounting the microphone in a mic stand

or shock/suspension mount you must ensure that

you do not block any of the slots on the side of the

microphone (as illustrated below).

Obstructing these slots will affect the sound quality

and the polar pattern (directional qualities).

• The NTG-3 is designed for operation within

demanding environments, where the traditional

condenser microphone would fail. However all due

care should be taken to protect the microphone

body itself from high levels of moisture or dust.

For maximum protection please store the NTG-3 in

the supplied storage cylinder when not in use.

• Shotgun microphones have a narrow ‘pick-up’

angle or polar response, and so can be used to

great effect with cameras for news gathering,

wedding videos, sporting events or in any

situation where you want to focus on a particular

area of sound source without having your audio

overpowered by ambient noise.

The pick-up pattern of the NTG-3 has been

tailored to be slightly wider and therefore more

directionally forgiving than comparable shotgun

microphones on the market. This makes boompole

and handheld operation much easier.

• The NTG-3 is supplied with a foam windshield.

This windshield should be used whenever

recording outdoors, as even an unexpected slight

breeze can cause unwanted sound interference.

• For maximum wind protection a more specialised

wind shield is recommended, such as the

DeadCat, WS7 deluxe windshield, or the

Blimp suspension windshield system.

• The supplied weather resistant aluminium

storage cylinder is designed to provide extreme

environmental protection for your microphone

when not in use, however it is not recommended

that the cylinder be immersed in liquid. Damage

to the microphone caused by water entering the

storage cylinder is not covered by the microphone

warranty.
