Introduction

You now have a complete solution for routing high quality audio in and out of your computer.
This Guide provides a detailed explanation of both the hardware and accompanying control software "Saffire MixControl" to help you achieve a thorough understanding of the product's operational features. We recommend that both users who are new to computer recording, as well as more experienced users, take the time to read through the user guide so that you are fully aware of all the possibilities that the Saffire PRO 24 and accompanying software has to offer.
If the main User Guide sections do not provide the information you need, be sure to consult http://www.focusrite.com/answerbase, which contains a comprehensive list of common technical support queries regarding the product to date.

Basics

The Saffire PRO 24 hardware interface provides the means for connecting microphones, line-level signals, instrument-level signals, and digital signals to your computer, which are then routed to your audio recording software / digital audio workstation (referred to throughout this user guide as "DAW").
All audio signals connected to the inputs, plus audio output from your computer programs are routed to the physical outputs for you to connect to an amp and speakers, powered monitors, headphones, analogue/digital mixer, and any other studio equipment that you wish to use. There are also connectors for sending and receiving MIDI.
The accompanying software application, Saffire Mix Control provides further recording, routing and monitoring options, as well as the ability to control global hardware settings such as sample rate and synchronisation.
Saffire MixControl software provides mixing and routing to and from the DAW, allowing control over which signals are sent from the sequencer to each output. All inputs on the Saffire PRO 24 are routed directly to your DAW software for recording, but Saffire MixControl also allows you to route these signals to your monitors so that you can listen to the audio signals with zero latency - before they arrive at your DAW.

Box Contents

Along with your Saffire PRO 24 you should have:
1 - 6 pin – 9 pin FireWire cable (also known as an IEEE1394 cable)
1 - Universal DC power supply unit (PSU).
1 - Software download card containing a unique "bundle code" granting access to all necessary software for this product. Please refer to the "Getting Started Guide" for instructions.
4 - Self adhesive rubber feet - to be fitted to base of the Saffire PRO 24
1 - Focusrite and Novation product brochure

Getting Started

The Saffire PRO 24 has a single 6 pin FireWire ports on the back. This FireWire connection will work with any of the current FireWire standards and connectors; FireWire 400 (6 pin or 4 pin connection); and FireWire 800.
BEFORE YOU CONNECT THE SAFFIRE PRO 24 TO YOUR COMPUTER, PLEASE REGISTER YOUR PRODUCT, THEN DOWNLOAD AND RUN THE INSTALLER. This will ensure that the correct drivers are used, thus preventing any unexpected behaviour.
The Saffire PRO 24 ships with a 6 pin – 9 pin FireWire cable (FW400 – 800).
You may have a FireWire 400 connector on your computer. In this case you will need to purchase a 6 pin FireWire 400 to 400 cable.
The Saffire PRO 24 can be powered via the FireWire connection when using 6 pin FireWire 400 or FireWire 800. When connected to a 4 pin FireWire you will need to use the supplied PSU.
You may have a FireWire 400 connector on your computer. In this case you will need to purchase a 6 pin FireWire 400 to 400 cable. Alternatively, you may only have a Thunderbolt port on your computer. Firewire is compatible with Thunderbolt through the use of an Apple Firewire to Thunderbolt adapter.
Note:
FireWire considerations - Most computers will generally be equipped with 1 FireWire bus. You may have multiple FireWire ports (connectors) on your computer, but these are all connected to 1 physical chip which controls the bus.
The FireWire bus is limited in the amount of data bandwidth it can handle. Each additional FireWire device connected to the FireWire bus demands additional bandwidth resources, thus increasing the chances of exceeding the total available bandwidth. Consequently, it is recommended that Saffire PRO 24 run on its own FireWire bus for best performance.
The Saffire PRO 24 should be able to work alongside other devices connected to the same FireWire bus. However, problems may arise depending on which FireWire devices are connected. For example, a FireWire disk used for back-up or a digital camera should not cause any problems, but when streaming audio from a FireWire hard disk or a FireWire box such as Focusrite Liquid Mix, the total FireWire bandwidth may be reached. This will result in audio drop outs, or reduced performance on either the Saffire PRO 24 or the other connected FireWire device.
For this reason, we would recommend that you use a separate FireWire bus for each FireWire device. This may be a PCI / PCIe card in your desktop, or a PCMCIA or Express card in your Laptop.
In order to maximise the life of your FireWire ports, we recommend that you do not connect or disconnect your Saffire PRO 24 whilst bus powered.

Note on FireWire Connection and Disconnection
All Saffire units adhere to the IEEE1394 (FireWire) standard, however it may be the case that the FireWire port on your computer motherboard or FireWire card does not.
Connection and Disconnection from a FireWire port that does not adhere to the IEEE1394 standard may result in permanent damage to both the Saffire and your computer.
To prevent permanent damage:
Connecting your unit(s)
Ensure that the computer is turned OFF
Connect the Saffire to your computer
Attach power supply if necessary
Turn ON your Saffire
Turn ON your computer
Turn ON your monitor speakers
Disconnecting your unit(s)
Shut down Saffire MixControl
Turn OFF your monitor speakers
Turn OFF your computer
Remove power supply if used
Disconnect your Saffire

Saffire MixControl

The Saffire MixControl software allows flexible mixing and routing of all audio signals to the physical audio outputs, as well as control of output monitor levels. All sample rate selection, digital syncing and buffer size settings (Windows only) are available from Saffire MixControl.
To open Saffire MixControl:
Windows
Start > Programs > Focusrite > Saffire MixControl.
Mac
Open Finder > Applications > Saffire MixControl.
This is how the Saffire MixControl Graphical Interface will appear on your computer.

Pre-amp Section

When connecting a Microphone to the Saffire PRO 24, you must connect an XLR cable to the Combi inputs on the front panel. When connecting either Line level signal or Instrument signal to the combi inputs, you must select either Line or Inst from the pre-amp section.

Additional Line level sources can be connected to inputs 3 and 4 on the rear of the unit. The Pre-amp gain for Inputs 3 and 4 can be set to either Lo (low) or Hi (high) gain. The maximum input level before the signal will clip for each setting is as follows:
Low Gain: 0dBFS = +16dBu
High Gain: 0dBFS = -10dBV (~-6dBu)

Mixer Section

The Saffire MixControl software includes a total of 8 mixes, each with a maximum of 18 channels in the mix. Up to 8 mono mixes or 4 stereo mixes, (or any combination of mono and stereo mixes) are available, making up a total of 8 mix channels.
Each Mix can contain up to 18 of the possible 24 inputs signals, and each mix can be sent to any number of outputs.
Each mix shares the same source inputs, but all other mixer controls are independent in each mix.
The Mixer Section is used to create mixes for monitoring purposes. The mixes you create do not affect how the audio inputs are routed to the DAW, nor does it affect the audio level of the signal to be recorded. What you set up in the mixer section of Saffire Mix Control only affects what is heard in the outputs of the mix.
The recording levels that are sent to the DAW are therefore only affected by the input gain settings on the Saffire PRO 24, not the mixer.
The mixer section is useful for creating different simultaneous mixes. For example, you may wish to provide a headphone monitor mix for the recording artist which is different to the mix heard in the monitor speakers.
The artist needs to hear mainly the backing track, and a little of the recorded input signal. The engineer needs to hear mainly the recording artist's signal and a little of the backing track.
A separate mix can be created for both artist and engineer with the exact levels desired. Each independent mix is created on a different mix tab.

Mixer Tab
Each mix can be selected by clicking on the corresponding mixer tab.

Input Channel
Here is a picture of 2 mixer input channels. Below is a description of every component of a mixer channel.

Clip light
If the red portion at the top of the fader lights up, then the signal level is too high.
You will need to turn down the signal level by either using the gain knobs on the front panel for the analogue inputs, using the gain on the external devices connected to the digital inputs, or using the gain within the DAW.
Once the gains are lowered, click on the red portion to reset the clip light.

Mute

Pressing this button mutes the signal. Red indicates that Mute is active.

Solo

Pressing this button solos the signal. The level of the fader will affect the level of the soloed signal.
Yellow Indicates that Solo is active.

PFL (Pre-fade listen)

Pressing this button solos the signal and automatically routes it to Monitor 1 and 2. The level of the soloed signal is pre- fade (i.e. it will not be affected by the level of the fader). Green Indicates that PFL is active.

Stereo

Pressing this button combines 2 mono channels into 1 stereo channel.

Track Name
As a default, each track is given a number as a name. Double click to rename the track to something more useful such as 'Vocal Mic'.

Mix Output Channel

The output channel of the mix is where all the input channels are routed to and mixed together. The output channel gives you control of the overall level of the entire mix. You can send a mix to any or all hardware outputs; if a single output is selected this is displayed at the top of the output channel. "Many..." will be displayed if multiple outputs are selected.
The output channel can be either mono or stereo depending on the status of the stereo button. When the channel is set to stereo, you will see that the tab for that mix doubles in size. This is due to the fact that the stereo version takes up 2 channels of the available total output channel count.
Note that when pressing on the solo button on an output channel, that channel (i.e. the whole mix) is soloed and routed to Monitor outputs 1 and 2. This is a non-latching button.
You can name the current mix by typing the desired name in the text field below the output channel. You will see the name appear in the mix tab. For example, Mix 1 can be renamed "Monitor Mix", and Mix 5 named "Headphone 1 Mix".
To copy an existing mix to another mix, simply click on "Copy Mix To..." and select the mix to which you would like to copy. Note that you can only copy a stereo mix to another stereo mix, and a mono mix to another mono mix. Therefore you must make sure that you have correctly set up the output channels to either stereo or mono before copying the mix.
Click on "Sel..." to view a drop down menu of the available output destinations for the selected mix (see the drop down menu in the screenshot on the left side of this page). Select an output in this menu in order to choose the output destination for the selected mix.

Routing Section

The routing section allows you to set up which audio sources are to be routed directly to which physical outputs.

The routing section displays every physical output on the Saffire PRO 24 and the audio stream to be sent to that output is available for selection in a drop down menu to the left of that output.

Clicking on the box to the left of the output label will bring up a list of all available audio output sources.
The available sources include:

If you have named the mix (by clicking in the track name section – see previous chapter) then this name is displayed as the mix source name.
Note that the routing section is linked to the selection made for the output channel destination set-up in the mixer. If you have outputs pre-assigned from when you created your Mix, you will see the routing selections have been set up. Similarly, if you change the audio source from the routing section, the output of the mix will change automatically.
'Headphones 1' is a copy of line outputs 3 and 4. All audio routed to Line outputs 3 and 4 will be heard in Headphone Left and Right.
When working at sample rates of 88.2kHz or 96kHz, the total number of ADAT channels available drops to 4 channels "ADAT SMUX". At these sample rates, ADAT channels 5-8 for the ADAT connection are greyed out.

Routing Presets

Routing Presets are provided as a starting point for you to create your own routing and mixer set-ups.
These will enable you to quickly set up your routing for recording (monitoring your inputs); mixing (sending signals out to outboard processors or external mixer); or internal looping (routing audio between software applications without leaving the computer).

Clear
This turns off all output routing. This can be used to re-set the routing for when you need to completely restart a configuration, meaning you do not have to manually turn everything off first.

DAW Tracking
'DAW Tracking' is used for the initial recording process. It will automatically output DAW 1 and 2 to be sent to all Line outputs and hence your main monitors (1+2) and to Headphone outputs 1 and 2. All input channels must be monitored from within the DAW application.

Zero Latency Tracking
Zero Latency Tracking is used for the recording process. It will automatically output Mix 1 and 2 to all your Line outputs simultaneously, and hence will route to the main monitors (1+2), and to the Headphone outputs 1 and 2. Line inputs and DAW outputs must be set up in Mix 1 so that you are able to monitor these sources with zero latency. You must also ensure that you are not monitoring the same signals from within your DAW at the same time, otherwise you will be monitoring the same signal twice (once direct from Saffire MixControl AND a second time (with latency) from your DAW.)

Mixing
'Mixing' is used for the mixing process. When sending signals out to a mixer or to external processing hardware, hardware outputs are typically set exactly as they are set in the DAW software. DAW outputs route directly to the line output of the same number. (DAW outputs 1-10 to Monitor Outputs 1-2, Line outputs 3-6.)

Loopback
Use when recording from one software program to another. You can use loopback routing to record audio from e.g. your internet browser into your DAW, or to record from one DAW to another.
To prevent any audio feedback, make sure that the DAW you are recording into is not set to monitor its inputs. Alternatively, set the outputs of the DAW into which you are recording to 3 and 4; this allows you to monitor the inputs without feeding the signal back into the record stream.

Monitor Section

The output levels of the monitor outputs and line outputs are configured in the Monitor Section. You can set up your Saffire PRO 24 so that the audio sent to the line outputs are controlled by the software volume dial; independent of the software volume dial; or muted.

Monitor control enable buttons (1 to 6)

The monitor control enable buttons indicate which outputs are controlled by the monitor section on the GUI directly below the ten buttons. The Saffire PRO 24 can be set up so that you have hands-on control of volume levels, and depending on your monitoring setup, you may control no speakers, just a single pair of speakers, or up to 6 speakers simultaneously.
(All digital output levels are unaffected by the monitor section in Saffire Mix Control. Use the output levels of the DAW to control digital output levels.)
Each button can be set to 1 of 3 possible states:
Blue - this output is controlled by the below monitor section.

Red - this output is not controlled by the below monitor section and it is muted.

Grey - this output is not controlled by the below monitor section and it is at full level.

To set a button to its Grey state, SHIFT + Click the button.

When a Monitor control button is set to 'Grey', the signal routed to that output will be played back at full level. This may potentially result in a very loud signal being sent to your monitor speakers, headphones or other equipment.
Be cautious when setting your levels (in your DAW or the Saffire Mix Control Mixer) before setting the monitor button to Grey.

Monitor Presets drop-down menu
These presets allow quick changing of typical monitoring set-ups.

For the monitor presets to work, you must have your speakers connected to the line outputs as shown in the picture below.

Surround Sound Monitoring: Quad, 2.1, or 5.1.

Monitor Section Controls
The following controls in the Monitor Section will affect those channels that have been selected for monitor control (indicated with a blue button, see above.)

Monitor level control knob

Set the output level of all assigned outputs using this knob. The output level can be adjusted using the mouse and will affect all assigned outputs (as indicated with a blue button). The dB display below shows the current level to which the monitor knob is set.
Note that the front panel Monitor control affects only outputs 1 and 2, and is an additional volume control on top of the monitor level set in Saffire Mix Control software.

Dim switch

Attenuates the output level by 18dB.

Mute switch

Mutes the output.

Left Mute switch

Mutes the left output.

Right Mute switch

Mutes the right output.

Remember that these dim, mute and mono buttons only affect the outputs selected for control (i.e. Blue) in the monitor control section.

Device Status section

The Device Status section shows information about the sample rate, synchronisation and driver status of the Saffire PRO 24. The desired sample rate can be set as well as external synchronisation options for using the Saffire PRO 24 with external digital devices.

Sample rate display
This displays the current Sample rate at which the Saffire PRO 24 is running. To change the Sample rate, click on the red sample rate value and select 44.1kHz, 48kHz, 88.2kHz, or 96kHz,
Note: you must quit your DAW application BEFORE you make sample rate changes to prevent any undesirable side-effects in your DAW!

Sync Status display

Displays the currently selected sync source (red display) – To change the sync source, click on the red sync source value and select SPIDF -OPT, SPDIF, ADAT, or Internal.

Sync source locked display
Displays "Locked" when the Saffire PRO 24 has successfully locked to the specified Sync Source.
If "No Lock" is seen, then the unit has been unable to lock to either an external ADAT or S/PDIF signal. If this is the case, then please check that digital cables are secure in their input sockets, and that the external digital devices have been set up as master devices.

FireWire Driver
This should display "Connected" at all times when the Saffire PRO 24 is connected to the computer via FireWire. If this shows "Disconnected" please check FireWire connections, check that the unit is switched on etc. If it still shows "Disconnected" then restart the computer and then restart the Saffire PRO 24.

FireWire Driver In Use
When the Audio Applications are open and using the Saffire PRO 24 driver, the FireWire Driver Status will show 'In Use'. Various Settings will be unavailable until the Audio applications have been closed and the FireWire Driver Status and reverted to 'Connected'.

Unit Name Text Field
Allows naming of the Saffire PRO 24 unit. Double click in the field and enter your text. Press enter (return) on your computer keyboard to complete.

Settings Menu

This is a drop down menu containing all of the following items which allow you to set up different global/system configurations.
This is the only part of Saffire MixControl software where there are differences between the Windows and Mac versions.

Mac

Window

S/PDIF AC3
Allows the user to stream AC3 directly via the S/PDIF outputs. (AC3 is encoded 5.1 audio, e.g. from a DVD player, that will be sent via S/PDIF cable (RCA or Optical) to your 5.1 decoder.)
Please note: The Saffire PRO 24 is not an AC3 encoder/decoder and the signal must be output from your audio software as an encoded AC3 signal to be decoded by an AC3 receiver.

Firewire Driver Latency
The Saffire PRO 24 DSPs latency performance will be dictated by the Core Audio buffer size specified in your DAW (Mac,) or as set in the ASIO buffer size (Windows.) The Firewire Driver Latency affects the performance of the Core Audio or ASIO buffer settings. If you are experiencing clicks and pops or audio dropouts, this may be due to certain hardware in your computer that is affecting the performance of audio devices connected via FireWire. Rather than removing and replacing hardware (e.g. your graphics card or wireless internet card) trying a longer Firewire Driver Latency setting may solve the problem.

File Menu

Mac

Windows

Open - opens a File open dialog allowing selection of any pre-saved Saffire MixControl set-ups.
Save - opens a File save dialog allowing selection of a location into which your Saffire MixControl set-up can be saved. Subsequent saves overwrite the original file.
Save As - opens a File save dialog allowing selection of a location into which your Saffire MixControl set-up can be saved. Use this option if you want to keep your original saved set-up and create a new one with a different name.
Restore Factory Default - Causes the Saffire PRO 24 to revert to the original default state in which it left the factory. This can be used to globally reset all mixer, routing, and monitor settings, allowing creation of a new set-up from scratch.
Save to Hardware - This saves the current Saffire MixControl set-up to the Saffire PRO 24 hardware. If you are moving the Saffire PRO 24 from one computer to another and want to retain the set-up, then choose this option. Note that Saffire MixControl does not automatically load from hardware (as this would overwrite a current set-up); it must be loaded manually.
Load from Hardware - This loads the saved set-up from the Saffire PRO 24 hardware into the Saffire MixControl software.
As you can see from the above screen shots, 'Open', 'Save' and 'Save as' all have keyboard shortcuts. These are standard shortcuts for their respective functions, so if you are regularly changing settings for your various sessions, then the shortcuts will reduce your set-up time.
