Introduction

Thank you for your purchase of the RØDE NTG8

precision broadcast-grade shotgun microphone.

Based on RØDE’s award winning NTG3, the NTG8

is a broadcast quality RF-bias shotgun microphone

that exhibits increased directionality across a wide

frequency response range. This makes the NTG8

the perfect microphone for ﬁlm, television, sports

and outdoor broadcasting, live performance, or any

professional distance miking application.

Like the NTG3, the NTG8 features low self noise,

natural sound without colouration both on and off-

axis, and RF bias technology to ensure that it is almost

completely resistant to high humidity environments

which could make other condenser microphones fail.

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

warranty.

While there you can view studio/ﬁeld tips and

techniques, as well as browse the comprehensive

range of accessories for the NTG8 and other RØDE

microphones and products.

Powering the NTG8

• The NTG8 requires phantom power to operate.

This needs to be supplied via a P48V phantom

power supply which is available from most

professional video cameras, mixing consoles or

audio recorders.

• If the camera, console, or wireless transmitter does

not provide phantom power (44-52V min 2.5mA),

then an external phantom power supply will be

required.

*Online product registration required, subject to terms & conditions.

Visit rodemic.com/warranty for full details.

• 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 NTG8 features a custom designed XLR

connector that is specially designed to reduce

susceptibility to RF interference from devices such

as cell/mobile phones and other transmitters.

• The NTG8 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 moisture, dust or contaminants.

• 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 sound

source without having your audio overpowered by

off-axis ambient noise.

• The NTG8 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.

Using the NTG8

- 7 -

• To mount the NTG8 in the supplied SM8

shockmount, insert the base of the microphone

(with the XLR connector) into the rubber opening

closest to the grey cable management clips and

slide the microphone through all four rubber

mount openings.

Some pressure will need to be applied to insert

the microphone, as the openings must be tight to

secure the microphone.

• When mounting the microphone in the SM8 shock

mount or any mic stand or shock/suspension

mount take care not block any of the slots on the

microphone (as illustrated below).

Obstructing these slots will affect the sound quality

and the polar pattern (directional qualities).

• To adjust the SM8 mounting angle simply pull the

quick release handle open while supporting the

microphone.

The SM8 can now be freely adjusted through

approximately 190° (depending on cable XLR

connector and method of mounting.)

Once the required angle is achieved the quick

release handle can be pushed close to lock the

rotation.

If additional tension is required, there is a knob on

the opposite side of the quick release handle that

allows for ﬁne adjustment of the quick release grip.

• The SM8 features cable management clips on

either side to minimise noise transfer from cables.

When mounting the cable in the clip, please ensure

that the section of cable going to the microphone

has enough slack to not manipulate the

microphone position, and also to allow adjustment

of the mounting angle without having to reposition

the cable.

• The SM8 features a standard 3/8” thread in

the base, to allow for versatile mounting to a

boompole or microphone stand.
