9 | PreSonus 2008
GETTING STARTED

Start Page: Setup Area
Shows Active Audio Driver and Sample Rate and Provides Quick Links to
Configure Audio and MIDI
In the middle of the Start page, you will see the Setup area. Studio One Artist
automatically scans your system for all available drivers and selects a driver.
By default, it will choose a PreSonus driver if one is available.
Selecting a Different Audio Driver From the Start Page
If you do not see “PreSonus FireStudio” on the Start page when you launch
Studio One, click on the Configure Audio Devices link in the Setup area to
open the Audio Setup Options window.
In the Audio Device menu, select “PreSonus FireStudio.” Click the Apply
button and then OK.
After you have verified that the PreSonus FireStudio driver has been detected, please continue to Section
2.2.3 to set up your external MIDI devices. If you do not have any MIDI devices to connect at this time,
please skip to Section 2.2.4.
2.2.3 Configuring your MIDI devices
From the External Devices window in Studio One Artist, you can configure your MIDI keyboard controller,
sound modules, and control surfaces. This section will take you through setting up your MIDI keyboard
controller and sound module with the FireStudio. Please consult the Reference Manual located on your
Studio One Artist installation DVD for complete setup instructions for other MIDI devices.
Setting up an external MIDI keyboard controller from the Start page.
A MIDI keyboard controller is a hardware device that is generally used for playing and controlling other
MIDI devices, virtual instruments, and software parameters. In Studio One Artist, these devices are referred
to as Keyboards, and they must be configured before they are available for use. In some cases, your MIDI
keyboard controller is also used as a tone generator. Studio One Artist views the two functions of these types
of hardware as two different devices: a MIDI keyboard controller and a sound module. The MIDI controls
(keyboard, knobs, faders, etc.) will be set up as a Keyboard. The sound module will be set up as an
Instrument.
10 | PreSonus 2008
GETTING STARTED
1)
From the Setup area in the Start page, you can also set up your
external MIDI devices. Before we set up a new Song for recording,
let’s take a moment to configure external devices. Connect the MIDI
Out of your external MIDI controller to the MIDI In of your
FireStudio.
2)
Click on the Configure External Devices link in the Setup area on the
Start page to launch the External Devices window.
Click the Add button.
3)
The Add Device window will launch.
From the menu on the left, select “New Keyboard.” At this point, you
can customize the name of your keyboard by entering the
manufacturer and device names.
Specify which MIDI channels will be used to communicate with this
keyboard. For most purposes, you should select all MIDI channels. If
you are unsure of which MIDI channels to select, we suggest you select
all 16.
4)
In the Receive From drop-down menu, select the MIDI interface input
from which Studio One Artist will receive MIDI data. In this case,
choose “FireStudio MIDI.”
In the Send To drop-down menu, select the MIDI interface output
from which Studio One Artist will send MIDI data to your keyboard
(also labeled “FireStudio MIDI”). If your keyboard controller does
not need to receive MIDI data from Studio One (say, for moving
motorized faders and the like), you can leave this unselected. If your
keyboard does need to receive MIDI date, you must connect a MIDI
cable from the MIDI output of the MIDI breakout cable to the MIDI
input of the keyboard.
5)
If this is the only keyboard that you will use to control the virtual
instruments and your external synthesizers in Studio One Artist, you
should check the box next to Default Instrument Input. This will
automatically assign your keyboard to control all MIDI devices in
Studio One Artist.
Click OK.
If you have a sound module you’d like to connect, leave the External
Devices window open and proceed to the next part of this section. If
not, you can close this window and skip to Section 2.1.4.
Setting up an external MIDI sound module from the Start page:
11 | PreSonus 2008
GETTING STARTED
MIDI instrument controllers (keyboards, MIDI guitars, etc.) send musical information in the form of MIDI
data to tone modules, which respond by generating sound, as instructed. Tone modules can be standalone
sound devices or can be integrated into a controller, as with a keyboard synthesizer. Studio One Artist refers
to all tone generators as Instruments. Once you have set up your MIDI keyboard controller, take a moment to
configure your sound module.
1)
Connect the MIDI In of your external sound module to the MIDI Out
of with your FireStudio.
2)
In the External Devices window, click the Add button.
3)
The Add Device window will launch.
From the menu on the left, select “New Instrument.” At this point,
you can customize the name of your sound module by entering the
manufacturer and device names.
Specify which MIDI channels will be used to communicate with this
keyboard. For most purposes, you should select all MIDI channels. If
you are unsure of which MIDI channels to select, we suggest you select
all 16.
4)
In the Send To drop-down menu, select the MIDI-interface output
from which Studio One Artist will send MIDI data to your sound
module, in this case, choose “FireStudio MIDI.”
In the Receive From drop-down menu, select the MIDI-interface
output from which Studio One Artist will receive MIDI data from your
sound module (also labeled “FireStudio MIDI”). In most cases, your
sound module will not need to send information to Studio One, so you
can leave this unspecified.
Click OK and close the External Devices window. You are now ready
to start recording in Studio One Artist. Sections 2.2.4 through 2.2.6
will go over how to set up a Song and will discuss some general
workflow tips for navigating through the Studio One Artist
enviroment.
12 | PreSonus 2008
GETTING STARTED
2.2.4 Configuring Audio I/O
Now that you’ve configured your MIDI devices, let’s create a new Song and set up your default Audio I/O.
1)
From the Start page, select “Create a new Song.”
2)
In the browser window, name your Song and choose the directory in
which you’d like it saved. You’ll notice a list of templates on the left.
The FireStudio template will create a Song with a track for each of the
available inputs. Every track is armed for recording, and no further
setup is required. Simply select this template and click “OK.”
The rest of this section will guide you through creating a Song from an
empty session.
3)
To begin a new Song, select “Empty Song” from the Templates list. At
this point, you should give your Song a name and select your preferred
sample rate and bit depth. You can also determine the length of your
Song and the type of time format you would like to use (Notation Bars,
Seconds, Samples, or Frames). Click the OK button when you are
finished.
If you plan on importing loops into your Song, you may want to select
“Stretch Audio Loops to Song Tempo” so that any loop of a known
BPM (like those in the included content library) will import at the
correct tempo.
4)
When the Song window launches, launch the Audio Setup window by
going to File|Options… (PC) or Studio One|Preferences (Mac), and
click on the Audio Setup button.
5)
Click on the Song Setup button to open the Song Setup window, then
click on the on the Audio I/O Setup icon.
13 | PreSonus 2008
GETTING STARTED
6)
Click on the Inputs tab in the Audio I/O Setup window, and you will
see all of the available inputs on your FireStudio. At this time, you
can add the number and type of inputs you plan to use. We
recommend that you create a mono input for each of the 26 inputs on
your FireStudio. If you plan on recording in stereo, you should also
create a stereo bus and assign it to the appropriate set of inputs. You
can remove any bus by simply selecting it and clicking the remove
button. To customize the name of your buses, double-click on the
default name to open a text box. When you have finished typing, hit
Enter.
If you would like the same inputs to be available every time you
launch Studio One Artist, click the “Make Default” button.
7)
Click on the Outputs tab, and you will see all of the available outputs
on your FireStudio. At this time, you can add the number of output
buses to which you would like to have access and can give them
custom names.
In the lower right corner, you will see the Audition select menu. This
allows you to choose the ouput from which you will audition audio
files prior to importing them into Studio One Artist. In general, you
will want this to be the Main Out bus.
If you would like this output configuration available every time you
launch Studio One Artist, click the Make Default button.
2.2.5 Creating a Song
Now that you’ve configured your MIDI and Audio I/O and created a new Song, let’s go through some of the
basics of Studio One Artist so you can start recording!
Creating Audio Tracks
In the upper left corner of the Arrange window, you will notice several buttons.
The middle button is the Add Tracks button. Click this button to bring up the
Add Tracks window.
In the Add Tracks window, you can select the number and type of Tracks you’d
like to create (Mono Audio, Stereo Audio, Instrument, or Automation) and
can customize the name and the color.
14 | PreSonus 2008
GETTING STARTED
Once you have added your Tracks, you can assign the input by simply clicking
on the input to which a Track is currently assigned. This will bring up your
inputs list. You can also access the Audio I/O Setup from here.
If you would like to add a Track for each of the available inputs and have the
routing automatically assigned, simply go to Track | Add Tracks for All Inputs.
To begin recording, create an audio track, assign it to Input 1, and connect a microphone or instrument to
Channel 1 on the front panel of the FireStudio. Select the record enable ( ) and monitor ( ) on your track
in Studio One Artist. Turn up the Channel 1 gain knob on the front panel of the FireStudio while
speaking/singing into the microphone or playing your instrument. You should see the input meter in Studio
One Artist react to the input. Adjust the gain so the input level is near its maximum without clipping.
Connect a set of headphones to the FireStudio headphone output. You may also wish to connect monitors to
the FireStudio’s Main Outs. You are now ready to record. For complete instructions, please consult the
Studio One Reference Manual, which is located on your Studio One Artist Installation DVD.
Creating MIDI Tracks
Click on the Add Tracks button. When the Add Tracks window launches, select
Instrument as the Track Format and click the OK button.
To assign your MIDI input, click on the MIDI Inputs list and select your
external sound module.
If you have added Virtual Inputs to your session, you will also see them as
available inputs.
If you selected your MIDI keyboard controller as the default keyboard, it will
already be selected. If not, choose your MIDI controller from Output menu
directly below.
To the left of the Add Track button, you will find the Inspector button. Click it
to display more parameters for the selected track.
At the bottom of the Inspector menu, you will see your Bank and Program
selections. From here, you can remotely change the patch on your sound
module.
15 | PreSonus 2008
GETTING STARTED
Please Note: MIDI data does not contain audio signals. To hear your sound module, you must connect the
audio output of the sound module to a FireStudio audio input, then connect the FireStudio’s audio outputs to
a sound system. (You also can listen on headphones, using the FireStudio’s headphone output.) When you are
ready to mix your Song, you must convert the recorded MIDI data to an audio waveform by recording a new
audio track.
Adding Virtual Instruments and Plug-in Effects to your Song
You can add plug-ins and Instruments to your Song by dragging-and-dropping from the browser. You can
also drag an effect or group of effects from one channel to another, drag in customized effects chains, and
instantly load your favorite virtual-instrument patch without ever scrolling through a menu.
In the lower right corner of the Arrange window are three buttons. The Edit
button opens or closes the Audio editor or the MIDI piano-roll editor, depending
on what type of track is selected. The Mix button opens and closes the mixer
window.
The Browse button opens the Browser window, which displays all of the
available virtual instruments, plug-in effects, audio files, and MIDI files, as well
as the pool of audio files loaded into the current session.
To add a virtual instrument to your session, click the Browse and Instrument
buttons to open the Instrument Browser. Select the instrument or one of its
patches from the Instrument Browser and drag it into the Arrange view. Studio
One Artist will automatically create a new track and load the Instrument as the
input.
To add a plug-in effect to a track, click the Effects button and select it or one of
its presets in the Effects Browser, then drag it over the track to which you
would like to add it.
Audio and MIDI files can also be quickly located, auditioned, and imported into

2.2.6 Cue Mix and the FireStudio
In Studio One, it is possible to quickly and easily create multiple cue mixes. A cue mix is separate from the
main mix and is usually provided to musicians for monitoring purposes during recording.
For instance, when recording vocals, the engineer and vocalist will probably want to hear different mixes.
Most vocalists want to hear more of their vocals in the mix, possibly with some reverb to make it sound
natural, while the engineer might focus on how the performance balances with the rest of the mix. Together,
Studio One and a FireStudio make this simple.
1)
You can create a cue mix and send it to any of 18 outputs on your
FireStudio (General Purpose, ADAT 1 out, and S/PDIF). You simply
need to create an output bus and enable Cue Mix. To begin, create a
new Song, open the Song|Song Setup. Click on the Audio I/O Setup
icon, switch to the Outputs tab, and add a new Stereo Output channel.
2)
Specify that this output is a cue-mix output by clicking on the channel’s
Cue Mix checkbox. You can create a cue mix for any or all of your
audio interface’s available stereo outputs. You can customize each Cue
Mix name by double-clicking on the default name.
When you are finished, click “Apply” and then “OK” to exit.
The Cue Mix Object
Once you have created a Cue Mix output, you will notice a special Send object in
the channels of the Console. This Send object is called a Cue Mix object. In the
Small Console view, Cue Mix objects appear in the far left column of the
extended channel. In the Large Console view, Cue Mix objects appear below the
Send device rack on each channel.

Activate Button
Sends a Channel to the Cue Mix
To completely remove any channel from a cue mix, simply deactivate the Cue
Mix object for that channel.

GETTING STARTED

Horizontal Level Fader
Sets the Volume of the Channel for the Cue Mix
By default this level will be identical to the level set on the channel’s fader. Once
you move the Cue Mix level fader, the volume of that channel in the Cue Mix will
be independent of the main mix or any other Cue Mix in the session.

Horizontal Pan Fader
Sets the Pan Position of the Channel for the Cue Mix
By default, the pan position will be identical to the position set in the main mix.
Once you change the pan position in the Cue Mix, the panning for that channel
will be independent of the main mix or any other Cue Mix in the session.

Lock to Channel Button
Locks the Volume and Panning in the Cue Mix Object to the Levels Set in the
Main Mix
By default, the Lock to Channel button is enabled, and level and pan values are
locked to the Channel level and pan faders. This means that each cue mix will be
identical to the main mix in the Console. Changing the level or panning in the
main mix will change the level or panning in the cue mix. However, changing the
level or panning in the Cue Mix object will unlock both settings, allowing
independent control of level and panning for each channel in each cue mix. Thus,
the level and panning for channels in a cue mix can be completely different from
the related level and pan in the main mix. At any time, you can lock the cue-mix
level and pan back to the channel settings by clicking on the Lock to Channel
button.

Zero-Latency Switch
Enables Zero-Latency Monitoring for FireStudio Inputs
Cue mixes are normally used in a recording situation in which one or more live
inputs need to be monitored. FireStudio interfaces feature internal hardware
mixers that provide zero-latency monitoring via the device window in the
Universal Control. While these mixers are easy to use, Studio One makes it even
easier by allowing you to control the mixers from within the software. Using this
feature only involves clicking just this one button.
You will notice that the FireStudio Device Window remains active while Studio One Artist is open. Because
of the powerful routing flexibility in the FireStudio Device window, FireStudio owners have the choice to use
either the FireStudio Device window or Studio One Artist’s Cue Mix feature to create their monitor mixes.
Please note: once Studio One Artist launches, DAW streams 1 through 18 will be patched to Outputs 1
through 18 on the Outputs/Router tab. If you make any changes to the FireStudio Outputs/Router tab while
Studio One Artist is open, and you want to use Cue Mix, you will need to repatch the DAW streams to their
respective outputs. For more information on Universal Control and the FireStudio device window, please
review Section 3.1. Because of FireWire streaming limitations, cue-mix zero-latency monitoring is not
available when daisy-chaining multiple FireStudio-family interfaces.
18 | PreSonus 2008
GETTING STARTED
The Main Output as a Cue Mix
It is possible to designate the main output in Audio I/O Setup as a cue mix. This is helpful if you often record
yourself require quick access to zero-latency monitoring for live inputs. When the main output is designated
as a cue mix, a Zero Latency button will appear on any audio channel with an assigned audio input in the
Console, below the Mute, Solo, Record, and Monitor buttons.
With the Zero Latency button and Monitor Enable both engaged, you will hear the live zero-latency input
straight from your FireStudio (as opposed to through software). As such, you will no longer hear the effects
of any inserts on the channel. However, you will still hear the result of any sends on the channel, as Bus and
FX Channels will still output normally.

2.3 SAMPLE HOOK UP DIAGRAMS
With the FireStudio, you can simultaneously record and play back up to 26 channels. Since it is loaded with
eight preamplifiers, you can plug in eight microphones to the FireStudio. Using the ADAT optical and S/PDIF
inputs, you can connect external A/D devices like the DigiMax FS. This makes recording extremely easy. All you
need are microphones, cables, and monitor speakers.

2.3.2 Full Band Setup Using the MSR in Track Mode
Please note: This setup can be used with or without an MSR connected. This example implies that seven monitor mixes have
been created in the FireStudio Device window and routed to the 8 General Purpose outputs of the FireStudio and 4 of the
DAC outputs on the DigiMax FS in stereo pairs. The seventh mix is assigned to an unused output and copied to the Main
Outputs for control room monitoring (see below). By connecting an ADAT cable to both the input and the output of the
DigiMax FS, it can be used to expand the outputs of the FireStudio as well as to add more analog inputs.

CONTROLS AND CONNECTIONS
3.1 UNIVERSAL CONTROL AND THE FIRESTUDIO
Like all members of the FireStudio family of interfaces, the FireStudio is compatible with Universal Control.
Universal Control is a powerful, flexible, and easy to use control-panel application that enables you to create 9
mixes from your input and output signals and lets you patch any input or playback stream to the first 18 of your
FireStudio outputs. This application also allows you to daisy-chain FireStudio-family interfaces. The FireStudio
can be connected to up to 3 other FireStudio-family devices, creating a system with a maximum of 52 inputs and
outputs.
Universal Control consists of the Launch window and the Device window. In the Launch window, you can set
basic parameters such as sample rate, clock source, and buffer size. The Device window of the FireStudio is the
FireStudio Mixer. The Mixer section of the Universal Control Panel was designed to look and feel like a
hardware mixer, so most of the features may already be familiar to you. From this mixer, you can create a zerolatency mix for each output and can route playback streams from your host application.
3.1.1 Universal Control Application Icon
If you are using Microsoft Windows, once you have successfully installed your
FireStudio, the Universal Control will be available from the Notification Area of your
taskbar (typically at the bottom right corner of your screen, near the clock).
The Universal Control icon is red when your FireStudio is disconnected or not installed and blue when the
FireStudio is connected and properly installed.
Open the Universal Control by double-clicking the blue Universal Control icon or by right-clicking the icon
and selecting “Open PreSonus Universal Control.”
Right-click the Universal Control icon and select “Quit” to exit the Universal Control application and remove
it from your taskbar. The Universal Control application can also be accessed from the PreSonus folder in the
Start Menu.
Mac OS X users will find the Universal Control application in the Applications folder. We
recommend that you move it to your Dock for easy access.

CONTROLS AND CONNECTIONS
3.1.2 Launch Window
From the Launch Window, you can set all the basic controls for your FireStudio.

Sample Rate Selector
Changes FireStudio Sample Rate
You can set the sample rate to 44.1, 48, 88.2, or 96 kHz. A higher sample rate
will increase the fidelity of the recording but will increase the file size and the
amount of system resources necessary to process the audio.

Buffer Size Selector
Changes the FireStudio Buffer Size (Windows PCs Only)
You can set the buffer size from 64 to 4,096 samples. The buffer size determines
the latency, which is the roundtrip time it takes audio data to be converted from
analog to digital and back to analog. As a general rule, the higher the buffer size,
the better the system performance, but the less playable virtual instruments
become. In general, 512 samples (11 to 12 milliseconds) will provide you with a
buffer that is large enough for optimum system performance, but small enough to
be unobtrusive. You should set your buffer size and sample rate prior to
launching your host applciation.
On Macintosh, the buffer size is set from inside your host application.



Clocksource
Normal Mode. Input and Output buffers are both identical to the Buffer
Size setting.
Safe Modes 1-3. Increases the Output buffer size for added stability.
Changes the Clock Source for the FireStudio
The clock source setting will determine the port from which the FireStudio is
receiving word-clock information. This keeps the FireStudio in sync with other
digital devices. You can choose between Internal, BNC, S/PDIF, ADAT 1, or
ADAT 2.
In general, you will want the FireStudio to be your master clock, in which case
you should set the clock to "FireStudio - Master." This setting also means that
your FireStudio is generating word clock and sending this information out of its
digital outputs.
If you want the FireStudio to receive sync from an external device, choose the
digital input to which the external device is connected (i.e. S/PDIF, ADAT, or
BNC Wordclock). The FireStudio's sync light will flash from blue to red. When
the FireStudio is in sync, the light will be blue.
Please note: When slaved to an external clock, the FireStudio will not
automatically change its sample rate to match the external clock. As a result, it
may fail to sync to the clock source. If your FireStudio is not syncing to an
external source, make sure that both your master device and the FireStudio are
set to the same sample rate.

3.1.6 The Device Window: Outputs / Router Matrix
True to its name, the Outputs/Router Matrix is the section of the FireStudio Device window where you have
full control of the physical outputs of your FireStudio. The Matrix Router allows you to create custom
routings of inputs and playback streams to any output. With the Outputs/Router Matrix you can:
•
•
•
Route a monitor mix to a stereo output
Assign every input and playback stream to its own output
Do quick AD/DA conversion on the fly
The Matrix Router can do it all quickly and easily. This is the virtual patch bay for your FireStudio recording
environment.
A quick note on playback streams: Wherever you see "DAW" in the FireStudio Device window, this is a
playback stream from your host application (or DAW). Traditionally, if you want to route a track in your
DAW to a physical output on your interface, you assign this output in your host application. Because the
FireStudio Device window provides much more flexible routing, you can now route this same track to one
output or to every output, by itself or as part of a mix.
For example, if you choose "FireStudio Out 4" for a track or virtual instrument in your DAW, FireStudio Out
4 will indicate a virtual output rather than a physical output. This track is now "DAW 4" in the FireStudio
Device window. The track can still be routed to the FireStudio's physical output 4, but you can also route it to
output 2 or 16 and include it in the monitor mix assigned to outputs 7 and 8. We'll get to that a little later.
Please note: ADAT 2 outputs (FireStudio outputs 17-24) can be directly accessed from your DAW
application; no additional routing is available in the FireStudio Device window.

3.1.7 The Device Window: Mixer tab
The FireStudio Device window allows you to create 9 stereo monitor mixes. The mixes can be renamed and
saved. You can also rename you inputs and playback streams.
It is important to mention that these mixes have no effect on what is being recorded in your host application.
This has obvious advantages. However, it is vital to remember that lowering the fader in the FireStudio
Device window on a channel strip that is clipping will not lower the signal that may also be clipping in your
host application. You must set the level for the recording using the physical trim pots on the face of the
FireStudio. If your signal is too hot in your DAW, it is these pots that will need to be lowered.
The Mixer is made up of 18 inputs and 18 playback streams (Standard Mode) or 26 inputs and 10 playback
streams (Expanded Mix Mode), each with its own channel strip. Just like in the Outputs / Router Matrix, you
have control both over your physical inputs and you playback streams from your host application.
Across the top row, you will see your Analog, S/PDIF, and ADAT 1 inputs. Across the bottom row, you will
see your playback streams. In Expanded Mix Mode, you will also see your ADAT 2 inputs. These playback
streams come directly from your host application. Each track or Virtual instrument in your session can be
assigned from within your host application to a FireStudio output. This output will be reflected as a
corresponding DAW channel in the FireStudio Device window.
Channel Fader Controls
Each input and playback stream is equipped with its own fader strip. This strip has all the same features as a

3.1.8 The Device Window: Naming inputs and mixes
You can customize the names of inputs, playback streams, and mixes on the FireStudio Device window. Once
these names have been changed on the Mixer tab, the changes will be reflected on the Output/Router Matrix
tab, making it easy to know at a glance what is connected to each input and for whom each monitor mix was
created.
To name your mixes, simply right-click or CTRL-click on the mix name you wish to change. A text box will
appear where you can type in the new name.
In this way, you can name all nine monitor mixes.
Once you have named all your mixes, you will see these same custom names on the Output/Router Matrix
when you click on a Mix Source button.
You can also name your inputs and playback streams. Each mix will reflect the changes you make to the
scribble strip on each channel and, again, these changes will also be viewable on the Output/Router Matrix.
To change the inputs, simply double-left-click on the input name and type the name you wish to use instead.
Renaming your inputs and mixes allows you to fully customize your FireStudio Device window for faster
mixing and routing and lets you get down to the business of making a successful recording.

3.2 FRONT PANEL LAYOUT

Microphone Preamplifier. Your FireStudio is equipped with eight custom designed PreSonus XMAX
microphone preamplifiers for use with all types of microphones (including dynamics, condensers, and
ribbons). As well as instruments and line-level signals. The PreSonus preamplifier design employs a
Class A input gain stage. This arrangement results in ultra-low noise and wide gain control, allowing
you to boost desirable signal without increasing unwanted background noise.
o
48-Volt Phantom Power. The FireStudio has 48V phantom power available in two groups via
button switches on the front panel. The top button activates phantom power for channels 1-4.
The bottom button activates phantom power for channels 5-8.

o
XLR-connector wiring for phantom power:
 Pin 1 = Ground
 Pin 2 = +48V
 Pin 3 = +48V
+14 dBu Headroom. The FireStudio microphone preamplifier has +14 dBu headroom. This
feature gives you wide dynamic range and excellent transient-response characteristics.
o
Combo Connectors. Each channel of the FireStudio has a Combo mic/line connector. This
connector lets you use either female ¼” phone or XLR connectors in the same jack. The ¼”
inputs on channels 3-8 are line-level inputs. When these inputs are engaged, the microphonepreamp circuit is bypassed.

Instrument Inputs (Channels 1 and 2). The ¼” TS connector on Channels 1 and 2 are for use with an
instrument (guitar, bass, etc.). When an instrument is plugged into the ¼” input, a high impedance
input buffer is switched into the preamp circuit and the FireStudio becomes an active instrument
preamplifier.
NOTE: Active instruments are those that have an internal preamp or a line-level output. Active
instruments should be plugged into a line input rather than into an instrument input. Plugging a linelevel source into the instrument inputs on the front of the FireStudio not only risks damage to these
inputs but also results in a very loud and often distorted audio signal. Therefore, don’t plug a line-level
source into the combo jacks of channels 1 or 2.
These two channels also feature a send and return on the back panel of the FireStudio. The return
inputs can be used as line-level inputs for these two channels if instrument preamps are not needed.

Input Gain/Trim Control. These knobs provide the following gain structure:
o
XLR Microphone Inputs: 54 dB of variable gain (-4 dB to +50 dB)
o
TS ¼” Instrument/Hi-Z Inputs: 54 dB of variable gain (-4 dB to +50 dB)
o
TRS ¼” Line Inputs: 32 dB of variable gain (-16 dB to +16 dB trim adjustment)

Main. The Main knob controls the output level for the main outputs on the back of the FireStudio and
has a range of -80 db to +10 dB.

Phones. The Phones knob controls the output level of the headphone output on the front of the unit.
Notice the volume indicator goes to 11; use this setting with extreme caution.



Red-Blue Power/Sync Light. This light is a clock source (sync) indicator. It lets you know if your unit is
receiving word clock correctly. Word clock is a signal with which digital devices sync frame rates.
Proper word-clock sync prevents digital devices from having pops, clicks, or distortion in the audio
signal due to mismatched digital-audio transmission.

CONTROLS AND CONNECTIONS
3.3 BACK PANEL LAYOUT

Power Adapter Input. This is where you plug in the proprietary power supply. The FireStudio features a
locking connector to ensure solid power connectivity.

FireWire Ports. There are two standard six-pin FireWire ports on the back of the FireStudio. Either
(and only one) should be used to connect your FireStudio to a FireWire port on your computer. If your
computer has a four-pin connector (commonly found on laptops), you will need a four-to-six-pin
connector to connect your FireStudio to your computer.
Use the second FireWire port to connect additional FireWire devices to you computer (such as external
hard drives).

MIDI Input and Output. MIDI stands for “Musical Instrument Digital Interface.” However, MIDI can
be used for many things other than instruments and sequencing. The MIDI inputs and outputs on the
back of the FireStudio allow connection to a variety of MIDI-equipped hardware, such as keyboard
controllers, and can be used to send and receive MIDI Machine Control and MIDI Time Code.
Note: MIDI does not carry audio signals but is frequently used to trigger or control an audio source,
such as a virtual instrument or hardware synthesizer. You should ensure that MIDI data is correctly
sent and received by the appropriate hardware or software. You may also need to route hardware sound
sources’ audio to the FireStudio. Please consult the User’s Manual of your MIDI devices for help with
MIDI setup and usage.

BNC Input and Output. These allow the FireStudio to receive and transmit word clock to and from
other digital audio devices.
You will need to select “wordclock” as the Clock Source and set the sample rate to correspond to the
external device in the Universal Control Launch window when using the BNC input. A 75Ω BNC wordclock cable is required to achieve proper sync.
38 | PreSonus 2008
CONTROLS AND CONNECTIONS

ADAT–S/MUX Input and Output These are the ADAT–S/MUX connections for your external digital
devices. When recording or playing back at 44.1 kHz or 48 kHz, each ADAT I/O will provide 8 of the
16 channels consecutively from left to right. When recording or playing back at 88.2 kHz or 96 kHz,
each connection will provide 4 of the 8 channels.
o
o
ADAT 1: Channels 1-8 (44.1/48 kHz) or 1-4 (88.2/96 kHz)
ADAT 2: Channels 9-16 (44.1/48 kHz) or 5-8 (88.2/96 kHz)
The ADAT–S/MUX I/O also allows the FireStudio to send and receive word clock to external digital
devices.
You should select “ADAT 1” or “ADAT 2” as the Clock Source and set the sample rate to correspond
the external device in the Universal Control Launch window when using one of these inputs for external
sync.

S/PDIF In and Out Jacks. The S/PDIF standard allows two channels of audio to be transmitted at rates
up to 24 bit, 96 kHz. The S/PDIF I/O also allows the FireStudio to send and receive word clock to
external digital devices.
You should select “S/PDF” as the Clock Source and set the sample rate to correspond to the external
device in the Universal Control Launch window when using the S/PDIF input for external sync.

Aux Input. This unbalanced stereo RCA input is for use with any device with an analog RCA output.
This input is only available when the MSR is connected. It allows quick comparison of your internal mix
with other playback material (e.g., comparing your mix to a CD). To listen to this input, select the Aux
button on your MSR.

Remote Control Input. This is the connection for the optional MSR: Monitor Station Remote. The MSR
connects to the FireStudio with a standard CAT5 (Ethernet) cable.
39 | PreSonus 2008
CONTROLS AND CONNECTIONS

Main Output. This stereo TRS output derives its source signal from the FireStudio Device window, as
described in Section 3.1.6. This output level is attenuated by the Main Level control on the front panel
of the FireStudio.

General Purpose Line Outputs (TRS Balanced). These are general-purpose line-level outputs. All eight
line outputs can be accessed in the FireStudio Device window and can be used for separate mixes,
additional speakers, external effects processors, etc.
Both the Main Output and the General Purpose outputs have additional functionality when an MSR is
connected to the FireStudio.
When using the MSR for monitor switching the outputs are routed as follows:
o
o
o
Main Output Left/Right. Monitor set A
General Purpose Outputs 7/8. Monitor set B
General Purpose Outputs 5/6. Monitor set C
When using the MSR for 5.1 surround-sound monitoring, the General Purpose outputs are assigned as
follows:
o
o
o
o
o
o
General Purpose Output 1: Front Left
General Purpose Output 2: Front Right
General Purpose Output 3: Rear Left
General Purpose Output 4: Rear Right
General Purpose Output 5: Front Center
General Purpose Output 6: Sub
As mentioned in section 3.1.5, the Main Outputs can be used as the Front Left and Front Right
monitors when mixing in surround, or they can be assigned separately from the surround monitors.

CONTROLS AND CONNECTIONS

Return 1 and 2 (Line Inputs). These are the line-level inputs for channels 1 and 2. Their gain structure
is identical to the ¼” inputs for channels 3-8 and are typically used for signals not requiring
preamplification (CD/MP3 players, effects processors, etc.). These inputs are normalled to the channel
1 and 2 preamp outputs, so they take precedence over the corresponding Mic/Instrument input on the
front of the FireStudio. (This means that if a cable is plugged into the channel 1 return input on the
rear of the FireStudio, the channel 1 Mic/Instrument input will be inactive, and it will become active
again when the cable is removed from return input 1.)

Send 1 and 2 (Preamp 1 and 2 Outputs). These ¼” jacks are balanced outputs of the preamps on
channels 1 and 2. They are half-normalled to the preamp inputs 1 and 2, so plugging a cable into either
of the preamp outputs does not interrupt the signal flow from the preamps to the AD converter.
Note: The Send outputs are typically used for patching in external signal processors (such as
compressors, limiters, EQs, and de-essers) to process the audio signals on channels 1 or 2. These
outputs are not connected to the digital-to-analog converters and so are only capable of routing the
input signals from channels 1 and 2. If you need to route recorded audio or input from channels 3
through 8, you will need to use the FireStudio Device window to route the input to one or more of the
General Purpose Outputs.
4.1 USING MULTIPLE FIRESTUDIO-FAMILY INTERFACES
Universal Control allows you to connect up to two FireStudios or to connect any member of the FireStudio
family of interfaces with any other. Once you have installed the Universal Control and FireStudio-family driver
on your computer, no further installation is required for any FireStudio product to connect to your system.
PreSonus supports the connection of up to four devices or a limit of 52 inputs and outputs (whichever comes
first) to any one system at a time. However, the ability to use more than two units simultaneously depends on
your computer’s specifications and optimization. If you plan to use three or more units at the same time,
installation of a dedicated FireWire bus with a tested and approved FireWire chipset and at least 2 GB of RAM
is highly recommended. A list of approved chipsets can be found in Section 5.1 of this manual. Updated lists are
available at www.presonus.com.
Below is a diagram showing the possible device combinations that you can use with your FireStudio Mobile and
the resulting input and output count.

TECHNICAL INFORMATION
How to Cascade Multiple FireStudio Interfaces:
The first time you add any FireStudio-family interface to your system, please follow these guidelines:
1. Go to www.presonus.com and check for the latest version of the Universal Control application.
2. Connect and sync each of your FireStudio-family interfaces to your computer separately before
cascading them.
3. Once a unit is individually connected, launch the Universal Control application. In the Launch window,
go to Settings | Check Firmware and verify that each unit has the latest firmware.
4. When the last unit has been updated, connect a second unit to the auxiliary FireWire port on the back
of the first unit. Allow the second unit to sync to your computer.
5. Connect additional units to your computer in this manner, one at a time, allowing each to sync before
connecting another FireStudio-family interface.
6. Once all your units are connected and synced, launch the Universal Control application. The individual
Device Window Buttons will be shown in the Launch window in the order of their internal ID number.
The unit with the lowest ID number will always be at the top of the list. This unit will also be the first
set of inputs and outputs your DAW application sees. The unit with the next highest ID number will be
the next set, and so on. Because of this, it is important to cascade your FireStudio interfaces in the
proper order from your computer so that you know which input belongs to which unit.
Please note: The order of the inputs and outputs in your FireStudio chain cannot be altered.
If you are using two or more of the same model (e.g., two FireStudios), you will need to look at the
serial number on the bottom of each unit (the internal ID number is the same as the unit’s serial
number) and connect them to your computer from lowest to highest. You may also wish to give each
unit a custom name. To do so, simply double-click on the name badge on each unit’s Device Window
button to open a test box. Once you have typed the custom name, hit the Enter key.
If you are using two or more different FireStudio family interfaces, make sure to reconnect them in the
order that their individual Device Window Buttons appear in the Launch window. Connecting your units
in this order will produce the best performance and will put your inputs and outputs in the correct order.
It is important to mention that the inputs and outputs on each unit in the chain are independent from one
another. This means that you cannot monitor the inputs from the first unit in the chain through the outputs on
the second unit in the chain unless you create a mix from within your DAW application. To easily maintain zerolatency mixing between the daisy-chained units, dedicate a set of outputs and a set of inputs from each device in
the chain to send a receive a mix in the Universal Control application.

TECHNICAL INFORMATION
5.1 TROUBLESHOOTING
Many technical issues can arise when converting a standard computer into a digital audio workstation (DAW).
PreSonus can only provide support for issues that directly relate to the FireStudio interface and Studio One
Artist software. It may be necessary to contact the manufacturer of the computer, operating system, and thirdparty DAW software to obtain additional technical support. PreSonus does not provide support for issues
regarding operating systems, additional hardware, or non-PreSonus software. Please check our Web site,
www.presonus.com, regularly for software information and updates, firmware updates, and technical support.
You also can get technical assistance by calling PreSonus at 225-216-7887 Monday through Friday between the
hours of 9 a.m. and 6 p.m. Central Time. PreSonus Technical Support can also be contacted during the same
hours via email at techsupport@presonus.com.
Pops and Clicks
Pops and clicks in either your input or playback audio are typically caused by momentary losses of
synchronization between the FireStudio and its clock source. This can be due to a FireWire card that is not
suited for FireWire audio devices or to a lack of CPU power or available memory. Try closing all unnecessary
programs, increasing the buffer size in the FireStudio Device window, and optimizing your operating system for
audio.
Pops and clicks exclusive to the digital inputs or outputs are typically caused when the FireStudio is not digitally
synced to the external digital device. If this is the case, ensure your FireStudio and external digital device are
properly synced. Please consult your external device’s user manual for details on syncing it to your FireStudio.
Flashing Sync Light
The FireStudio’s Sync light flashes red and blue when it is not synced. Check the FireWire cable to ensure that it
hasn’t become disconnected. If you are using an external digital device, and your Clock Source is set to the
correct digital input, set the sample rate in the Universal Control launch window to the same sample rate as that
of your master clock. If you are not using an external device to generate word clock, open the Universal Control
Launch window and set the Clock Source to “Internal.”
Audio Dropouts
Audio dropouts can occur when the speed of your processor cannot process the audio buffer fast enough.
Increase your buffer size in the FireStudio Device window and try the different Operation Modes on the
Hardware Settings tab.
No Input Signal on Channels 1-8
1. Check your mic cable. In order to access the microphone preamp, you must use an XLR cable. The TRS
connection in the combo jacks for inputs 3-8 bypass the microphone preamp entirely.
2. Make sure the microphone does not require phantom power. If it does, press the 48V button. Note:
Engaging phantom power will place +48V on channels 1-4. Ensure nothing will be damaged by
phantom power being present on the adjacent channel.
3. If there is no signal on Channel 1 or 2, make sure nothing is plugged into the line input on the rear of
the FireStudio. The return inputs on channels 1 and 2 take precedence over the combo input on the
front of the unit for channels 1 and 2. If a cable is plugged into the return input on channel 1, then the
mic/instrument input on channel one will be inactive until the cable is removed from return input 1.

TECHNICAL INFORMATION
Recommended FireWire Chipsets
The FireStudio will work with a wide range of FireWire cards and configurations. However, due to the plethora
of FireWire chipsets currently on the market, it is not possible to thoroughly test each one for compatibility.
Most users will not need to alter their current PC configuration to use their FireStudio. The following FireWire
chipsets, however, have been tested and approved for use with the FireStudio:
•
•
•
•
Agere/LSI FW323-06
TI TSB43AB23
VIA VT6308
VIA VT6306 (On some older motherboards this chipset will only support a limited number of
playback channels: 32 channels at 44.1 or 48 kHz; 16 channels at 88.2 or 96 kHz.)
These chipsets are available on a wide range of motherboards and PCI/PCMCIA FireWire cards. Here is a brief
list of manufacturers and models of PCI FireWire cards:
•
•
•
•
•
•
•
Lucent IEEE 1394a
Syba SD-LUD-4F
HP PA997A
Eforcity PCRDFW31CON1
Sabrent SBT-VT6306
Micropac Technologies SBT-VT6306
SIIG NN-400012-S8
Please note: manufacturers may change chipsets at any time, so it is recommended to verify these models still
employ a chipset in the above list prior to purchasing.
At the time of the publication of this manual, PreSonus only recommends the following Express cards:
•
ADS Pyro 1394a
•
StarTech EC13942
Known Incompatible Hardware
•
ATI RADEON 9000/9001 IGP video chipset. Symptoms are consistent click and pops during audio
playback. This video chipset is only found in PC laptops and is entirely integrated as the computer’s
only video controller. PreSonus strongly recommends that users do not purchase a system with this
chipset as there is currently no workaround for this incompatibility.
•
USB/FireWire and s400/s800 combo cards. Symptoms usually include no audio
recording/playback, even though the device will install and sync, and erratic audio performance.
Rarely, combo cards will prevent the device from installing or achieving a stable sync. We
recommend FireWire cards that have S400 FireWire connections only.
•
FireWire cards with NEC chipsets. Symptoms include installation issues, erratic audio, and
extraneous static and noise.
•
Motherboards with nForce4 chipsets. Symptoms include reduced to very poor performance,
especially if using the onboard FireWire connection. Installing a PCIe (not PCI) FW400-only card
with an approved chipset is a known workaround but might not allow full performance.
