Hardware Controls and Analog/Digital Connections

The FIRESTUDIO can simultaneously record/playback a total of 26 inputs and outputs. The following will outline each connection type in detail from left to right on the front and back panels.

Front Panel

a.) 48 Volt Phantom Power: These two switches will activate phantom power for microphone preamps 1-4 and 5-8 respectively. Phantom Power is only active on the microphone XLR input.

b.) Neutrik Combo Connectors: These connectors can accept either 1/4 TS/TRS or XLR inputs. Channels 1 and 2 feature an instrument level input on the 1/4 connector for use as a Direct Injection input for guitar, bass, etc. Channels 3-8 accept line level input on the 1/4 connector. The XLR input on all channels accepts microphone level input.

c.) Gain/Trim Controls: Each channel has its own gain/trim control and clip light. The clip light will illuminate red when the preamp is clipping.

d.) Headphone Output: This headphone output can be assigned any output from the DAW or the FIRESTUDIO Control Console, and has its own level control.

e.) Main Level: This level control will attenuate the Main Output on the back of the FIRESTUDIO.

f.) Sync LED: This sync LED will illuminate RED when sync is NOT present and BLUE when sync is present, indicating whether or not the FIRESTUDIO is properly connected and installed to the computer, or properly synced to another device (via ADAT, SPDIF, or BNC).

g.) Power Switch: This power switch will turn on/off power for the FIRESTUDIO.

Back Panel

a.) Power Connector: This power connection allows the included power adapter to screw tightly in, insuring that power is not accidentally disconnected from the FIRESTUDIO.

b.) FireWire Ports: The included FireWire cable will connect to either port here from the computer. The other port can be used to daisy-chain another FIRESTUDIO.

2 Installation and Hardware Overview

c.) MIDI I/O: The standard MIDI input and output allow connectivity of any MIDI device to the FIRESTUDIO to be used in the DAW software.

d.) BNC Wordclock I/O: These standard BNC connectors allow you to connect any device with BNC input or output to the FIRESTUDIO. This is to allow the FIRESTUDIO to function as a master clock, or to slave to any other device.

e.) Dual SMUX Optical ADAT: These two inputs and outputs can be used to connect any 96k Dual SMUX ADAT device via standard optical cable to the FIRESTUDIO. These inputs and outputs can also function at 48k, allowing the connection of one bank (8 channels) or two banks of ADAT (16 channels). For more on how to use the optical ADAT I/O, please refer to section 4.1.

f.) SPDIF I/O: These RCA type connectors are for digital SPDIF connections up to a 96k samplerate.

g.) RCA: This unbalanced RCA input is for use with any device with an analog RCA output. This input is ONLY for use with the optional Monitor Station Remote, and allows quick comparison of any other playback material with the incoming input (ie; comparing the mix to a CD, etc).

h.) CAT-5 Connector: The optional MSR (Monitor Station Remote) connects here. For more information on the MSR, please refer to the PreSonus website (www.presonus.com).

i.) Main Out: This stereo TRS balanced output derives its output signal from the DAW, the FIRESTUDIO Control Console software, or the optional MSR remote. This output level is attenuated by the Main Level control on the front panel.

j.) General Purpose Outputs: These stereo TRS balanced outputs can be used for any purpose, and derive their output signal from the DAW, the FIRESTUDIO Control Console software, or the optional MSR remote. There are no level attenuators on the FIRESTUDIO for these outputs.

k.) Line Inputs 1 and 2: These are the 1/4 balanced line inputs for channels 1 and

2. These can be used with the preamp sends on channels 1 and 2 to insert an external processor, or simply as line level inputs as found on channels 3-8 on the front panel. l.) Preamp 1 and 2 Sends: This TRS balanced output will output any analog signal coming into the respective preamp BEFORE it is converted into digital format and sent to the computer. This can be used to send the preamp signal out to an external processor (ie; compressor, eq, etc), and back into the respective line input for that channel, where it is then converted and sent to the computer. These outputs are ONLY for channels 1 and 2 respectively.

Standalone Operation

The FIRESTUDIO is capable of operating in Stand Alone mode without a computer. The settings you make in the FIRESTUDIO Control Console application will be stored in flash memory on the FIRESTUDIO itself, allowing you to disconnect the FireWire connection from the computer and use any routing setup or hardware setting already made.

Heres an example:

If you are tracking a live show, you could route all of the inputs to analog or digital outputs (using the FIRESTUDIO Control Console) to feed a hard-disk recorder or other recorder for backup. If the computer stops working for any reason, the backup recording will be unaffected, as all of the routing youve created has been stored in flash memory in the FIRESTUDIO. This eliminates the need for a more elaborate live recording setup involving splitter snakes, etc.

Cubase LE Quick Start Up

Use the included Cubase LE installation CD to install Cubase LE. Proceed through the installation as it prompts you. Make sure to keep the CD envelope sleeve handy to reference the serial number during installation.

1. Once Cubase LE is installed, launch Cubase LE. First you must set Cubase LE to the FireStudio drivers. Click the Devices menu and then Device Setup.

2. Select VST Multitrack in the left column and then on the right side choose ASIO PreSonus for the ASIO Driver.

3. Click Switch.

4. Now click the File menu and New Project. Choose empty template and a Destination Location where your project will be saved to your computer.

5. Now click the Devices Menu and VST Inputs. Activate your additional input channels clicking the graphic power buttons.

• Notice that the input channels are activated in pairs. Adding one audio track is MONO. Meaning it will record from 1 input channel. It can be switched to a STEREO track. Meaning it will look to record from 2 input channels for a left and a right signal.

• Also, notice that your inputs are labeled for what they are. Mic/Inst, Mic/Line, ADAT 1, ADAT 2 and SPDIF. The Aux ADAT channels are only available when your FireStudio is set to 44.1k or 48k Sampling Rates.

6. Depending on the version of Cubase LE you have, there may be a limitation for the maximum number of record-enabled input channels you can have active at any time. Cubase LE 1.0.10 allows 8 active input channels. Other versions of Cubase such as SL3 or SX3 do not have these limitations.

7. Now click the Project menu, Add Track and Multiple.

8. This will add multiple tracks. Choose Audio for Track and set your Count to the number of audio tracks you want to add to your project.

9. Click Record Enable for each of your tracks. You will now notice a green level bar indicating the audio track is receiving signal. You can also click the Input Monitor if you want to monitor (listen to) the audio through Cubase while you record. If you do, remember to turn off the Input Monitor button to playback what you have recorded to your audio track. You can also monitor your input signals with the FireStudio Control Console by creating a mix or routing inputs directly to outputs.

10.Expand an audio track to reveal additional buttons. One is a Stereo/Mono switch. Do this if you are recording a stereo source like the left and right outputs of a keyboard or other stereo sound device.

11.Finally, click the record button on the Transport Bar to begin recording.

12.Click the Help menu and Documentations. There you will find the Getting Started and the Operation Manual for Cubase LE. Use these to further familiarize yourself with Cubase LE.

Control Console

Please install the FIRESTUDIO drivers and open the FIRESTUDIO Control Console before continuing through this section of the manual. A hands-on approach is very helpful in learning all of the features the Control Console has to offer.

The Control Console has two main tabs, found at the top left of the window, Mixer and Outputs/Router. Click on either tab to access the Mixer or Matrix Router. Depending on the situation you may not need to use the Mixer or Matrix Router, however, knowing how to use this software can greatly enhance the studios efficiency and ease of use. Heres a short list of what this software allows you to do:

• Create multiple monitor mixes of all inputs and playback streams (ie; not everyone in the band has to hear everything equally).

• Send analog inputs to digital outputs, and vice versa. (ie; the FIRESTUDIO can function as a standalone AD/DA with zero latency)

• Create sends and returns for any input to incorporate external processors with zero latency.

• Give every input its own hardware output for incorporation into a larger studio console or other recorder.

• Send mixes out of several types of outputs simultaneously (TRS, ADAT, SPDIF) to different devices for monitoring comparisons. Note that ADAT channels 9-16 are not currently available in the FireStudio in the Control Console. You cannot mix our route these channels with the FireStudio Control Console. These channels may be monitored via the DAW software.

Mixer

The Control Consoles Mixer is a flexible and easy-to-use solution for creating multiple mixes from the inputs and DAW playback streams, all with zero-latency. It is capable of creating 9 independent stereo mixes of all of the inputs and playback streams, and routing each mix to any stereo analog or digital output (except ADAT channels 9-16 when in 44.1k and 48k sample rates).

Great care has been taken to make this mixer look and feel like hardware, so most of the features will be familiar to an experienced engineer. The following describes the layout of the Mixer and how it works:

• The top row of tracks is colored in blue and includes all analog and digital inputs.

• The bottom row of tracks is colored in grey and includes all playback streams from the DAW software.

• There are tabs at the very bottom of the window to access each mix 1-9. These tabs can be renamed to anything you like by double-clicking on the name, typing a new name, and hitting enter on the keyboard.

• In the upper right of the window there is a Mix File section with load and save buttons. These buttons allow you to save the current mix of Mixer (one of the nine stereo mixes), and then load that setup at any time. Below that are copy and paste buttons which allow you to copy the settings for any mix and paste them to another mix.

• Below the copy and paste buttons is the stereo output track for the current mix, with quick output routing buttons below it. You can select any and/or all outputs for the current mix. Disengaging stereo output buttons reverts routing to previous setting. If there is no previous setting or if the Control Console was closed and then reopened, routing reverts to default.

Note: All settings for the Mixer are stored in flash memory on the FIRESTUDIO, and will be recalled each time the FIRESTUDIO is connected to the computer and the Control Console is opened.

Track Elements

1. Pan Bar: This allows you to pan the track left or right, and shows numeric readout of the current setting.

2. Fader, Level Meter, Clip: Control and monitor the level of the track. A red C will illuminate when the track has clipped (click on the C to reset).

3. Link: Click on the word Link in between two tracks to put them in stereo mode. The faders for each track will now move in unison and the pan for each track will move far left and right respectively. When the Link is disengaged, the pan values will move back to their original positions.

4. dB value: Numeric readout of level in Decibels below the fader/meter.

5. Mute, Solo: (M, S) Mute or solo the track.

6. Name: You can name the track anything you like by right-clicking in this space, typing a new name, and hitting enter on the keyboard (this name will show up for this input/DAW playback stream everywhere in the Control Console).

Matrix Router

The Matrix Router allows you to create custom routing of inputs and playback streams to any output for complete control of the studio. From simply routing a mix to a stereo output, to AD/DA conversion on the fly, to every input and playback stream having its own output, the Matrix Router can do it all quickly and easily. The following describes the layout of the Router and how it works:

• On the far left of the window there are two tabs, Inputs and Playback. These tabs allow you to flip between views that list either the 18 inputs or 18 playback streams.

• Below the two tabs is the Router Preset section. You will see a Default button, which sets the Router to a default state with all DAW returns routed to their respective outputs (ie; DAW 1/2 out of analog 1/2, etc). The user can save any routing scheme to any of the six presets by clicking on Save and then on the number they wish to save to.

• Below the Router Preset buttons are the source selectors for the Main Output, and the headphone outputs (1 headphone output is on the front panel of the FIRESTUDIO, the other 2 are on the optional MSR remote). These outputs mirror the hardware outputs, so you can monitor what is outputting from any given output pair (ie. quickly check a headphone mix you created for someone else).

• You can quickly audition any output pair through the main output or any of the headphone outputs. o For example, click on the word Main and you will see it highlight in blue. Now drag the mouse over any output pair to see a grey box with the word Main on it over the given output pair. Left-click to audition what is being routed to that output through the Main output, and double-left-click to assign the Main output to mirror that output pair.

• At the bottom of the window are the tracks for each hardware output pair. The Track Elements are identical to the assigned audio source except for LINK and MUTE. You will make these settings manually for the hardware output channels.

• The matrix is arranged in columns (vertical) and rows (horizontal). The columns correspond to each hardware output on the FIRESTUDIO, and the rows correspond to individual input or playback sources. You can select one cell per column, and up to every cell per row.

• When on the Inputs tab, notice that the bottom row of the matrix includes a quick selection cell for the playback streams. When on the Playback tab, notice that the top row of the matrix includes a quick selection cell for the input sources. When on either tab, the bottom row includes a quick selection cell for a Mix selection. Clicking on a quick selection cell will drop down a menu to choose the source for that cell.

• When the mouse is moved over any cell, you will see that cell highlight and name what you are routing, with a small popup window that lists what output you are routing to. Click on the cell to assign the routing for that source.

• If you have routed a Mix to any output, that routing will be reflected in the Output Router section of the Mixer for that mix.

• Once everything is setup the way you need, we recommend creating a preset using one of the six user definable Router Preset buttons. To create a preset, left-click on Save, and then choose the number preset to which the current setup will be saved. Then, click on any preset to restore its settings. NOTE: All settings for the Matrix Router are stored in flash memory on the FIRESTUDIO, and will be recalled each time the FIRESTUDIO is connected to the computer and the Control Console is opened.

CONTROL CONSOLE EXAMPLE SETTINGS

Example 1: All inputs routed to same channel outputs with optional Mix to SPDIF L/R output.

Example 2: All analog inputs to same channel analog and digital outputs with optional Mix to SPDIF L/R output.

Example 3: Analog input to digital outputs and digital inputs to analog outputs (AD/DA).

Example 4: All software (DAW) playback channels to all same channel Hardware outputs.

Example 5: 8 channels of software (DAW) playback channels to 8 channels of analog and ADAT outputs.

Example 6: 9 separate Mixes assigned to all FireStudio Hardware Outputs.

Hardware Settings

Click on the Hardware Settings tab to access the following:

1.) Sample Rate (PC Only*): You can set the sample rate to 44.1, 48, 88.2, and 96k. When set at higher than 48k, the ADAT channel I/O is limited to 8 channels utilizing both ADAT ports and the Dual SMUX standard. A higher sample rate will increase both the fidelity of the recording you will make and the subsequent file size for every audio file.

2.) Buffer Size (PC Only*): You can set the buffer size from 64 to 1024 samples per buffer. The buffer size will affect the latency (roundtrip time it takes audio data to go into the computer and get processed back out to the FIRESTUDIO). The lower the buffer size is set, the lower the latency will be, and the higher the stress will be on the computer. Thus, if you experience digital pops and clicks in the audio playback, try adjusting the buffer size higher to reduce the stress on the computer.

• When using a Mac and OSX, the sample rate can only be changed in the Audio MIDI Setup Application. Buffer sized are changed in the DAW.

3.) Clock Source: The clock source setting will determine where the FIRESTUDIO is deriving its clock. Unless clocking to an external device, the clock source should be set to Internal. You can choose between SPDIF, ADAT 1, ADAT 2, or Word Clock when selecting an external clock source. The FIRESTUDIO will sync to the samplerate the external device is set to when switched to any of the external clock sources, and the sync light will be blue if it is in sync.

4.) Terminate BNC: Check this box to terminate the BNC Word Clock input. This may need to be done to achieve stable sync depending on the external device you are syncing to via BNC Word Clock.

5.) Reset Names: Clicking on this button will reset all user-defined names in the Control Console.

Expanding The Inputs and Outputs

You can easily connect additional microphone preamplifiers to expand the inputs and outputs on the FireStudio via ADAT/SMUX optical light pipe connectors.

The DigiMax FS can connect to the FireStudio using 88.2k and 96k sample rates via dual SMUX optical ADAT using 2 standard optical cables audio.

If you are recording with sample rate settings of 44.1k or 48k, you can connect 2 DigiMax FS to the FireSTudio for 16 additional preamp inputs and line level outputs. Note that ADAT channels 9-16 can only be assigned within the recording software (DAW). You cannot mix or route the Auxiliary ADAT channels 9-16 in the FireStudio Control Console. Each DigiMax FS or other digital preamp will connect with 1 optical cable at 44.1k or 48k.

You can also further expand the FireStudio by connecting to the Digital SPDIF I/O. Two PreSonus Eureka channel strips can be connected using the Eurekas AD192 digital output card. Simply connect the SPDIF output on the Eureka to the SPDIF input on the FireStudio for two additional microphone preamplifiers. NOTE: Any time you connect an external digital device you must make sure the Master and Slave Clock Source settings are appropriate. Only 1 device can be the Master device that will generate clock. Every other device connected must be Slaved to the Master device. You must also make sure that Sampling Rate is set the same for each connected device.

Live Recording

Live Recording Scenario

This setup scenario makes computer recording primary to the P.A. system or House Mix. This setup scenario allows the FireStudio to preamplify the signals that will be recorded by the computer and then mixed by the Main Mixing Console or P.A. system.

1. Connect all audio sources to the FireStudio +/- DigiMax FS to be used as a preamp and computer recording. 2. Route all input channels of the FireStudio to all outputs of same channels in the FireStudio Control Console. 3. Connect all FireStudio +/- DigiMax FS outputs to Line Level input channels of the Main Mixing Console or P.A. system. NOTE: The routing of the FireStudio is zero latency and is saved in Flash Memory. If communication is lost between the FireStudio and the computer, the FireStudio will retain its routing settings and continue to pass audio. The signal to the Main Mixing Console or P.A. system will never be interrupted. See section 2.3, Stand Alone Operation.

Live Recording Scenario 2

This setup scenario makes computer recording secondary to the P.A. system or the House Mix. This setup will allow the Main Mixing Console to preamplify the signals that will be mixed to the P.A. system and then recorded by the computer.

1. Connect all audio input sources to the Main Mixing Console or P.A. system. 2. Connect the direct or AUX outputs of the Mixing Console to the Line Level input channels of the FireStudio +/- DigiMax FS. 3. Anything you do with the FireStudio Control Console in setup scenario 2 will be entirely for the own monitoring purposes while you are recording. 4. Note that changes made to the Mixing Consoles preamps will effect the recording levels.

Studio Recording

In the project or professional studio, the FireStudio is extremely powerful and flexible. Here are a few typical set up examples.

Create separate headphone mixes for each musician

Setup the recording software (DAW) respectively to record the input channels to individual tracks. Doing so is specific to the recording software (DAW).

The FireStudio Control Console allows you to create up to 9 separate Mixes for each of the artists in the studio. You can control what each of the artists hear and what they want or need to hear.

For instance, the drummer might only want to hear the click track and a bass guitar, while the vocalist may not want the drums in his headphones or monitors.

Mix 1 might typically be the Control Room mix, the mix that the engineer wants to hear. Mix 2-9 can be specific to each of the artists and can be assigned to any hardware output of the FireStudio.

You can then connect headphone amplifiers and or monitors to the FireStudios hardware outputs. NOTE: you can assign a Mix to any Hardware Outputs with the Quick Output buttons in each Mixer view and also in the Output/Router view. The Engineer can also audition the audio for any hardware output. Reference audition feature outlined in section 3.3 Matrix Router and see Example 7.

Mix outside the computer using a mixing board or summing mixer

Connect all hardware outputs of the FireStudio to the line level inputs of the mixer board.

Then return the Main or an Aux L/R output of the mixer board to available input channels of the FireStudio. 31
