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
register your microphone for a free ten year extended
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.

• 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

• 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.
