OVERVIEW

Overview

Introduction

Welcome to your new Vocaster One audio
interface. Vocaster One is designed for
podcasters, vloggers, voiceover artists,
streamers, audiobook creators, and more.
With Vocaster One and the included Vocaster
Hub software you can record studio quality
audio to your computer and camera.

We’ve designed Vocaster One for users of all
experience levels. With features such as Auto
Gain and Enhance you can achieve clear and
consistent recordings quickly.

The Vocaster Hub software is designed with
simplicity in mind. It provides easy access for
controlling Vocaster’s settings, and gives you
full control of your show’s mix as you send
it to your choice of recording and streaming
software.

Connect Vocaster One to a computer via its
USB-C port and the cable provided. You can
either live-stream audio in real time, or record
sound for later edit and upload.

Vocaster One also allows two-way connection
to a phone, letting you record interviews or
other audio from your phone to your camera
or computer. You can also record to the
audio track of a camera in perfect sync with
your video. You can monitor your stream or
recording process on either headphones or
loudspeakers.

The Vocaster One interface and the included
Vocaster Hub control software support both
Mac and Windows.

Vocaster One is also compatible with Apple
iPads with a USB-C port, so you can take
advantage of the additional portability and
convenience the tablet format provides.

If you can’t nd what you need in this User

Guide, please visit support.focusrite.com,
which has a Getting Started section, setup
guides, and technical support.

A video series explaining how to set up and
use Vocaster One is available from our Get

Started pages.

OVERVIEW

Hardware features

Vocaster One allows you to connect a high
quality microphone to a computer running
macOS or Windows: this lets you achieve a
much better audio recording than you would
get by using the microphone built into most
laptops or tablets.

The microphone input accepts a range of
microphone models, including both dynamic
and condenser types. If you are using a
condenser microphone, Vocaster One can
provide the phantom power (48V) it needs
to operate.

The microphone signal routes to your
computer’s audio recording software via the
USB-C connection at up to 24-bit resolution,
and 48 kHz sample rate. (24-bit/48 kHz is the
standard for most podcasts.)

If you don’t already have recording software,
we recommend Hindenburg. This is included
in the software package available to you free
of charge as a Vocaster owner.

A 3.5 mm jack socket allows you to connect
a phone to Vocaster One: a second, similar
socket allows connection to a video camera.

The phone connector is a TRRS: TRRS means
you get audio both in and out of the phone,
so you can record audio from the phone,
and the phone can also hear the other audio
sources you are recording to your show.

Vocaster One has outputs for both
headphones and speakers: a front panel ¼’
TRS socket for headphones and two rear
panel ¼’ TRS sockets for connection
to speakers.

The top panel has knobs for microphone gain
and listening level. The microphone control
is surrounded by ‘halo’ meters, showing both
the microphone signal level and the gain
setting. Three illuminated buttons start the
Auto Gain function, activate the Enhance
feature and mute the microphone. There are
also LEDs to show when phantom power and
the USB connection are active.

In the Box

Along with your Vocaster One you will nd:

• USB cable, Type ‘A’ to Type ‘C’

• Getting Started Information (printed
inside the box)

• Important Safety Information

As a Vocaster One owner, you are also
entitled to a selection of third-party software,
including the Hindenburg DAW (Digital Audio
Workstation) recording application. Go to

focusrite.com/Vocaster to see

what’s available.

System requirements

The easiest way to check your computer’s
operating system (OS) is compatible with
the Vocaster One is to use our Help Centre’s

compatibility articles.

As new OS versions become available over
time, you can continue to check for further
compatibility information by searching our
Help Centre at support.focusrite.com.

GETTING STARTED

All users:

If you have any issues using the Easy Start

tool, open the le More Info & FAQs, where
you should be able to nd answers to

your questions.

NOTE: When you install Vocaster Hub on a
Windows computer, the driver needed by

Vocaster One installs automatically. Vocaster
Hub and the Vocaster Windows driver are

always available to download at any time,
even without registering: see ‘Manual
Registration’ below.

Manual Registration

If you decide to register your Vocaster One
later you can do so at register. You need to
enter the Unique Product Number (UPN)
manually: this number is on the base of the
interface itself, and can also be found on the
barcode label on the side of the box.

We recommend you download and install our
Vocaster Hub software application, as this
unlocks the full potential of the interface. You
can download Vocaster Hub at any time from

downloads.focusrite.com.

Audio Setup in your DAW

Vocaster One is compatible with any
Windows-based Digital Audio Workstation
(this is the software you use to record and is
referred to as a ‘DAW’) that supports ASIO
or WDM, or any Mac-based DAW that uses
Core Audio. After following the Easy Start
procedure (see page 5), you can start
using Vocaster One with the DAW of
your choice.

Vocaster One lets you record all the sources
separately via the USB connection, for mixing
later, but also has a Show Mix input which is a
stereo mix from Vocaster Hub software.

To allow you to get started if you do not
already have a DAW application installed on
your computer, Hindenburg is included; this is
available to you once you’ve registered your
Vocaster One. If you need help installing this,
please visit our Getting Started pages here,
where a video tutorial is available.

Operating instructions for Hindenburg can

be found in the application’s Help les, or at

hindenburg.com/academy.

Please note - your DAW may not
automatically select Vocaster One as its
default Input/Output (I/O) device. In this
case, you must manually select Vocaster One/
Focusrite USB ASIO as the driver on your
DAW’s Audio Setup* page. Please refer to

your DAW’s documentation (or Help les) if

you are unsure where to select the ASIO or
Core Audio driver.

EXAMPLES OF USE

Examples of use

Vocaster One is the ideal audio interface for
live podcasting or voice recording, using a
Mac, PC, or iPad. A typical set of connection
possibilities is shown below.

Recording with a microphone

This setup shows a typical conguration for

recording from a microphone using software
on your Mac, PC, or iPad. You can record your
voice while listening to yourself and any other
audio via headphones.

Apart from the headphone socket, all
Vocaster One’s connections are
on the rear panel. Connect your
computer or laptop to the USB port
(marked ) using the USB cable
supplied. Turn the unit on with the
Power button.

The microphone input is an XLR socket
and work with microphones with an XLR
connector. You can use Vocaster One
can with most models of microphone,
including dynamic and condenser types.

We recommend dynamic microphones
for speech recording, as they deliver
good quality in the frequency range of
the spoken word, and can help reduce
unwanted noises in your surroundings
from being picked up.

Two types of dynamic microphone

focusrite.com Tell the world 11

EXAMPLES OF USE

Recording with a microphone (cont.)

Vocaster One can provide phantom power (48 volts) at the XLR input
if you’re using a condenser microphone. To enable phantom power,
push the 48V button on the rear panel: the 48V LED lights red to

conrm it’s active.

Dynamic microphones do not require phantom power. It’s rare, but
you can damage some microphones using phantom power. We
recommend turning off phantom power when you use a dynamic
microphone. If you are unsure whether your microphone needs
phantom power, please check its documentation.

Microphone setup

Vocaster One has two ways of setting the correct microphone level.
‘Gain’ is the term we use to describe how much you are boosting
your microphone signal.

You can either set the level automatically with Vocaster One’s
Auto Gain feature, or manually. Both methods are described in the
next sections.

focusrite.com Tell the world 12

EXAMPLES OF USE

Using Auto Gain

Vocaster One’s Auto Gain feature allows you to
get a good recording level without guesswork.

Press the button to activate Auto Gain, if you
have Vocaster Hub open on your computer, by
clicking on the on-screen Auto Gain icon.

The Auto Gain button will pulse amber.

Vocaster One

Vocaster Hub

Speak into the microphone for ten seconds,
using a normal speaking voice you will use for the
recording itself.

The halos acts as a count down timer, starting fully
white, then moving towards the bottom. Vocaster
Hub also shows a progress bar.

Halo countdown on Vocaster

Auto Gain didn’t set my input level

If the halos ash amber the signal is too loud
or too quiet so Auto Gain couldn’t set the correct
level and sets it to the minimum or
maximum level.

If the halos ash red Auto Gain couldn’t set a

usable level. This could be due to a Mic Level that
was too low:

• Test a different microphone or cable.

• Make sure 48V is on, if you’re using a
condenser microphone.

• Make sure you switch on your microphone
(if it has an on/off switch).

Vocaster Hub countdown

After ten seconds, Auto Gain sets the input level
for the microphone and you’re ready to record.

focusrite.com Tell the world 13

EXAMPLES OF USE

Manual gain adjustment

On Vocaster One, the large knob
marked sets the microphone
gain, and the level to your recording
software.

The gain knob is surrounded by two
LED ‘halo’ indicators, shaped as arcs.
These light in various colours to show
the microphone signal level.

To set your gain, speak into your
microphone as if you were recording,
adjust the gain knob until the halo(s)
just start to turn amber when you speak

48V

at your loudest. At this point, turn the
knob down a bit until you don’t see
any amber. If the halos ever turn red,

you will denitely need to turn the gain

knob down: red means your recording is
likely to distort. (See diagrams below.)

You can also adjust the gain from
Vocaster Hub by moving the on-screen
Mic Level slider: drag it to the right to
increase the gain.

When you’re adjusting the gain by
turning the knob, the left halo changes
to white to show the gain setting.

EXAMPLES OF USE

Microphone Mute

Vocaster One’s microphone channel has a
mute button, marked .

Vocaster One

Vocaster Hub

You can press this at any time to turn the
microphone ‘off’: the button lights red and
the gain halos pulse red while the microphone
is muted.

Using Enhance

Vocaster One’s Enhance feature optimises the
microphone’s audio processing to achieve the
best possible recording.

It uses compression to control the level of the
microphone signal, equalisation to help voice

recordings sound clearer and a high pass lter

to remove unwanted low frequencies such as
rumbling and microphone handling noise.

Enhance has four presets for you to tailor the
sound to your voice or your intended. You can
select one of the four presets using the drop­down arrow in Vocaster Hub:

• Clean

• Warm

To use Enhance, either press the button or,
if you have Vocaster Hub open, click the on­screen Enhance icon.

The button lights green when Enhance is on.
Press it again to turn Enhance off.

Press the button again to unmute. You can
also click the button with the same icon on

this feature as a ‘cough switch’.)

focusrite.com Tell the world 15

EXAMPLES OF USE

Listening with headphones

You can connect headphones to the front
panel headphone socket marked to hear
what you are recording.

This is a ‘default’ mix of your microphone and
any other audio sources, such as audio from a
phone or computer playback (the Loopback
channels).

You can adjust the volume of individual audio
sources using the mixer in Vocaster Hub.

You can adjust the volume in the headphones
with the control on Vocaster One marked

: this control does not affect your

recording level.

The Host level controls both the
headphones and speaker outputs. When
you’re using headphones we suggest muting
your monitors in Vocaster Hub.

Connecting to active speakers

Listening with speakers

Use the ¼’ jacks marked Outputs R and L

to connect speakers. You can connect

powered monitors or an amplier to these

outputs. Speaker volume is controlled by the
same knob used for headphones volume.

The outputs are balanced ¼’ TRS jack
sockets and provide line level. Small powered
monitors have unbalanced inputs, typically
a 3.5 mm jack plug intended for direct
connection to a computer. Separate power

ampliers are likely to have phono (RCA)

sockets.

You can also mute the speakers using
Vocaster Hub software. Click the speaker icon
in the top right of Vocaster Hub software to
toggle mute on (red) or off (black)

NOTE: You can create an audio feedback loop
if your speakers are active at the same time

Connecting to passive speakers

as a microphone! We recommend you turn off
your speakers while recording podcasts, and
use headphones for monitoring.

focusrite.com Tell the world 16

EXAMPLES OF USE

Recording a phone

You can connect a phone to Vocaster One
to record a conversation, or to record
music from the phone.

The rear panel has a phone connector,
marked . This is a 3.5 mm TRRS jack
socket, use a 3.5mm TRRS jack cable
to connect to the phone’s headphone
socket, which is normally a 3.5 mm TRRS
socket.

A 3.5mm TRS cable will work, but you
may not get two-way communication with
your phone guest.

If the phone does not have a 3.5 mm
headphone port, you can use a 3.5 mm
TRRS headphone adaptor.

The connector also feeds Vocaster
One’s output back to the phone so the
person on the phone call can hear the
whole podcast mix, but without their own
voice. This type of mix is known as ‘mix­minus’: it ensures the caller will not hear
their voice delayed or with echoes.

The signal level to the phone depends on
the setting of the input channel sliders in
Vocaster Hub’s mixer, but is unaffected by
the master output slider. The signal fed to
the phone is a mono version of the stereo
mix, because the phone’s input is a mono
microphone.

Vocaster One records audio from a phone
in mono.

EXAMPLES OF USE

Recording to a video camera

If you are working with video, you may want
to record your audio into a video camera.
Vocaster One has a dedicated output
connector for this purpose, the 3.5 mm TRS
jack socket on the rear panel marked .

You can connect this output to the audio/
mic input on your camera using a 3.5mm
jack-to-jack cable.

If your camera input uses a different
connector, use a suitable adaptor cable.
Ensure you select your camera’s external
audio source rather than its internal
microphone.

The camera output carries the same mix as
the USB recording output, and what you
hear in your speakers and headphone. You
can set the mix and levels going to the
camera using the sliders in Vocaster Hub’s
mixer.

VOCASTER HUB SOFTWARE

Vocaster Hub software

As part of the Easy Start registration process,
you’ll install Vocaster Hub software on your
computer. Vocaster Hub gives you access
to additional Vocaster One features - most
importantly, it lets you balance your voice
against any other audio in your mix.

IMPORTANT: A separate Vocaster Hub
User Guide can be downloaded from the

downloads area of the Focusrite website.

This describes the use of Vocaster Hub
in full detail. The following section of this
User Guide is limited to an overview of the
software’s primary features.

To open Vocaster Hub: After you install
Vocaster Hub on your computer this icon
appears in your applications:

If your Vocaster One interface is not
connected to your computer and powered
on, you will see a Welcome Page.

Note the Help Centre or Contact Support
links. You can always return to this page by
turning the interface off. More guidance on
using Vocaster One, including tutorial videos,
are available at these links.

When you connect the interface and power
it on, the icon lights white to conrm
the interface is communicating with your
computer, and you’ll see Vocaster Hub’s
Control Page:

If the icon lights red, it shows Vocaster
One has not been able to communicate with
your computer, and you should check the
cable is plugged in correctly.

Click it to open Vocaster Hub.

Controlling the microphone

The Host Input panel is where you adjust
Vocaster One’s microphone channel:

The bar should remain green most of the
time, with amber showing only on the loudest
‘peaks’. If it goes red, the gain is set too high.

Below the meter/level display are three
buttons which duplicate those on the
interface top panel:

• Auto Gain – click this to start the
Auto Gain function; speak normally
into the microphone for 10 seconds to
calibrate the gain setting.

• Enhance – click on this to activate

can adjust the gain with either control. The
colour bar shows the microphone signal level,
and again, this duplicates the signal level halo
display on the interface.

focusrite.com Tell the world 20

VOCASTER HUB SOFTWARE

Controlling your mix

The Mix section of Vocaster Hub allows you to
balance the audio inputs and computer outputs
making up your Show Mix.

Like the Mic Level control, the ‘sliders’ are
both meters and level control. The sliders
affect the headphone/speaker mixes and
Show Mix recording but don’t affect the
level of each channel into your software. The
channels of the mixer are (left to right):

• Host (mono) – this is Vocaster One’s
Host microphone.

• Aux (mono) – use this when you have
connected a phone to the rear panel

connector. It adjusts the audio level

being received from the phone.

• Loopback 1 and Loopback 2 (stereo)–
these control the level of two audio
sources within your computer: these
could be feeds from the internet, pre-

recorded les, or other sources. In the

image below Loopback 1 is ‘clipping’ so
the source level needs turning down to
stop the red clip bar appearing.

• Show Mix (stereo) – this shows and
controls the overall output level of the
mixer.

On the Loopback 1 channel the red part of
the meter is the ‘Clip Indicator’. This shows
you the source is too loud and may distort
in your recording. Bluetooth and Loopback
are an exception and may show as clipped
more often.

Turn down the track’s source, not the
slider in the mixer. If the Show Mix clips,
turn down the tracks in the mixer.

focusrite.com Tell the world 21

VOCASTER HUB SOFTWARE

Recording sounds from your computer

Vocaster’s Loopback feature lets you record
audio sources from within your computer
(e.g., the audio output from a web browser).
There are two stereo Loopback sliders
on the mixer; these use Vocaster One’s
‘virtual’ inputs. The virtual inputs don’t have
connectors on the interface, but you can
record them in your DAW in the same way as
any other input.

• Loopback 1 – this input gets its signal
from software with its output set to
Playback 1-2, or software that doesn’t
support output routing. The software
you can use with Loopback 1 includes:

- Internet browsers

- Music playback software such as
Spotify or Apple Music.

- Video call and conference software.

You can feed each Loopback input from
a different software application. Which
application you use with each Loopback

input is congured in the application’s output

settings. If you’re a Mac User and wish to use
both Loopback inputs, we recommend you
read this support article.

• Loopback 2 – this input gets its signal
from audio software with its output
routing set to Playback 3-4. You can

congure this in the software’s audio

settings, but not all software allows
output routing selection, so please
check your software’s user guide for this
feature. Software with the ability to feed
audio to Loopback 2 includes:

- Other recording or playback software
you’re using.

- VOIP and video conferencing
applications.

Tell the worldfocusrite.com 22

VOCASTER HUB SOFTWARE

Example of Loopback usage

You might want to use both Loopback inputs
when you’re recording a show but need
independent recordings of other software
sounds to mix later. For example, in your
show, you want to record your conversation
with a guest in a video call in addition to
including a sound or jingle playback from
another audio playback software.

Your video call software (e.g., Zoom), routes
its output to Playback 1-2 by default. This
appears as Loopback 1 in the mixer. You
can then route the output of your playback
software to Playback 3-4, which becomes
available as Loopback 2.

In your recording software you can now have
separate tracks for recording:

• Loopback 1 appears on your DAW
channels 7 and 8

Recording Tracks into Software

Depending on which recording software you
use, you can pick from up to ten channels to
record from, to separate tracks.

The ten channels you’ll see are:
