Power requirements

The NT-USB is powered by your device’s USB port, meaning that in

most instances you can just plug the microphone in and get started

right away. For non-standard USB ports, a powered USB hub may

be required.

The NT-USB is a “Plug & Play” USB device, compatible with both

Windows and Mac computers, as well as the Apple iPad via the USB

camera connection kit (available directly from Apple).

The NT-USB features a purple LED inside the microphone cage

that indicates when the microphone has power. If the light does not

turn on after plugging the microphone in, the computer or device

you are using may not provide enough power for the NT-USB. If this

is the case, we recommend connecting the NT-USB via a powered

USB hub.

Warranty

The NT-USB is covered by a limited warranty for one (1) year from

the date of purchase. This can be extended free of charge to a full

two (2) year warranty by registering your microphone online by

visiting our website as above.

Diagram 2 - Adjusting the

microphone position

To change the microphone

position, always be sure to

loosen the adjustment lever to

ensure that you do not damage

the stand.

When recording vocals,

always use the supplied pop

filter, mounted in front of the

microphone. The pop filter will

prevent plosives (hard ‘P’, ‘B’, ‘T’

and ‘K’ sounds) from overloading

the microphone’s capsule.

Mounting the NT-USB

Diagram 1 - Mounting the NT-USB

in the supplied tripod stand

The NT-USB is supplied with

a high quality tripod mount.

To assemble simply screw the

mounting ring onto the tripod

stand (diagram 1). The mounting

ring can also be used as a mic

clip to attach the NT-USB to a

mic or boom stand.

To install the NT-USB in the

mounting ring place the micro-

phone in the mount from above

(optionally using the pop filter),

and thread into the mounting

ring. Once the microphone is

facing the correct way, turn the

dial at the bottom clockwise until

tight (diagram 1).

General operation

The gold dot on the face of the

NT-USB indicates the front of the

microphone, and the pickup area

of the capsule. The microphone

(and gold dot) should always be

facing towards the sound source

that you wish to record.

On the side of the NT-USB there

are two adjustment knobs.

Diagram 3 - Monitor mix control

and headphone volume control

Monitor mix control

The Monitor mix control (the top knob) is used to ‘mix’ between the direct

microphone signal (your voice for example) and the sound from your audio

recording software on your computer / device (the music that you are singing

along to). By turning the knob counter-clockwise, you will hear more of the

direct microphone signal, and less of the signal coming from the computer

/ device software. If you turn the knob clockwise, you will hear more of the

computer/device signal, and less of the direct microphone signal.

We recommend always beginning with the knob in the centre position. This

will ensure that you are hearing an equal balance of both the direct signal,

and the computer / device signal, enabling you to then achieve an ideal

balance between the signals.

Headphone volume control

The headphone volume control (the bottom knob) allows you to control the

volume of the playback through headphones connected to the NT-USB via the

headphone jack.

Recording vocals

We strongly recommend using the supplied pop shield for all vocal

recording. This aids in minimising plosive sounds (hard ‘P’, ‘B’, ‘T’

and ‘K’ sounds) that produce a sudden jet of air which can cause the

capsule to overload and produce a ‘popping’ sound.

Any moisture on the microphone capsule can cause problems for a

condenser microphone such as the NT-USB, however the use of the

pop shield will reduce the risk of this occurring.

Placement of the microphone and relative to the vocalist may

be varied on several factors including room acoustics, the vocal

performance, and whether the vocalist has a high or deep voice.

An ideal reference is to begin with the NT-USB with the pop shield

attached, mounted directly in front of the vocalist, approximately

15cm (6”) away. The pop shield will assist in keeping the performer

at a constant minimum distance from the microphone and helps

to maintain reasonable recording levels. Moving the vocalist a little

closer will make the vocal sound more intimate and full, while

moving the vocalist back will give the vocal a little more ‘air’ or

room sound, and will reduce the proximity effect (increased bass or

low frequency response when the sound source is very close)

Experimentation should be made with the angle from which the

microphone is addressed, as different results can be achieved when

the vocalist is ‘off-axis’ to the microphone (and the gold dot).

General operation cont.

Setting your input level:

The NT-USB has been set to an ideal internal gain setting, without

the need for physical level adjustments on the microphone body.

Any necessary level adjustments to set the ideal recording level

can be made from within your recording program, or via your

computer’s system preferences.

To adjust your input level from within your recording software, refer

to the manual provided by the software developer.

To manually adjust your input level via your computer’s system

preferences, use the following instructions relevant to your device

platform/operating system.

Adjusting the input level on a Mac OS computer:

1. Click on the Apple symbol at the top left of your screen, and

select System Preferences.
