Introduction Introduction Thank you for choosing Echo Digital A udio. We think you’ll find your Echo product to be an extremely flexible, high-performance tool for your com puter- based hard disk recording system.
Introduction System Requirements In order to use AudioFire2, AudioFire4, AudioFire8, or AudioFire12 you’ll need the following: An Apple brand Macintosh computer (desktop or notebook) with: Mac OS X (10.
Installation Installation To properly install your AudioFire product you will need to: log in as an administrator, check OS X version, run software update, connect the audio interface to a FireWire port and to your ot her audio hardware, install the Console software, and install Tracktion.
Installation Installing the AudioFire Hardware and Software Now that you have logged in as an admini strator, checked the OS X version, and updated your software, you are ready to install your AudioFire product in your computer. 1. Install the AudioFire Console.
Installation NOTE: You should check the driver downloads area of our website ( www.echoaudio.com ) for any software updates and install them before continuing. The AudioFire hardware must be installed and powered on for the firmware update to load properly.
Connecting to the Audio Interface Connecting to the Audio Interface The AudioFire2, AudioFire4, AudioFire8 and AudioFire12 audio interfaces contain a wide variety of connections that allow great flexibility in operation. For optimal performance, it is critical to us e the appropriate cabling and connectors.
Connecting to the Audio Interface Analog Inputs and Outputs – AudioFire4 AudioFire4’s front panel has two universal inputs (1 – 2) with meters and trim knobs, a phantom power indicator (+48v), and a power button with an amber power indicator light.
Connecting to the Audio Interface headphone output jack, with a corresponding volume knob, which monitors analog outputs 1 and 2. AudioFire8 has six analog line inputs (3 – 8) and eight analog line outputs on the rear panel. These analog inputs (3 – 8) operate with an input impedance of 10Kohms.
Connecting to the Audio Interface Universal Inputs – AudioFire4 and AudioFire8 The universal input connections can accept balanced or unbalanced signals via ¼” or XLR connectors. Since your AudioFir e has built-in preamps, you can just plug your microphone or guitar cable right into the universal input.
Connecting to the Audio Interface For optimal audio quality, you should adjust the input trim knob so that your loudest recorded signal lights up the yellow light, but not the red.
Connecting to the Audio Interface By default, the inputs and outputs are set to receive or send a +4dBu signal. You can switch between +4dBu and –10dBV for each individual input and output via the console software (see “Console” section below).
Connecting to the Audio Interface When connecting devices to the S/PDIF j acks, the use of standard analog RCA audio cables is not recommended. For re liable S/PDIF operation, 75-ohm coaxial (RG59) video cables are recommended. MIDI Your AudioFire is equipped with MIDI I/O connectors.
Connecting to the Audio Interface The S/PDIF connectors are used to transmit digital audio data between digital audio devices via an electrical signal. When connecting devices to the S/PDIF jacks, the use of standard analog RCA audio cables is not recommended.
Software Configuration Software Configuration Now that you have installed your AudioFire product, you can verify that everything is working properly. Open “System Preferences” fro m the Dock or Apple menu, select “Show All”, and select the “Sound” panel.
Software Configuration You can also check out your hardware with the “Audio MIDI Setup” application. Go to your Applications folder on your hard disk and from there to the Utilities folder.
Software Configuration By clicking on the “MIDI Devices” tab, you will display the available CoreMIDI devices. You should see your AudioFire product shown as an icon here. Next, you’ll want to install Tracktion and learn about the AudioFire Console software.
Installing Tracktion Installing Tracktion Your AudioFire comes bundled with the full version of Tracktion 1, audio multitrack recording, MIDI, editing, and sampling software. Install Tracktion from the AudioFire CDROM To install the software: 1. Insert the AudioFire CD-ROM into your CD-ROM drive.
Installing Tracktion Launching Tracktion and Assigning Inputs & Outputs Now it’s time to launch the actual program and set a few options: Locate and double-click the Tracktion icon in the “Applications” folder or wherever you copied it to earlier.
Installing Tracktion Audio Settings 1. Click the “Settings” tab at the top of the screen. 2. Select “Audio Devices” on the left. 3. Where it says “Wave device:” click on the drop down menu and select your AudioFire product. 4. Now you should be able to see a list of the available audio devices for your AudioFire product.
Console Software 28 Console Software Console If you followed the instructions in Step 1 of the “Installing the AudioFire Hardware and Software” section of this manual, then you installed a “virtual control surface” application called the Audi oFire Console.
Console Software 29 Console Software The AudioFire8 Console Window: Analog Out 1-2 Tab selected. Bus Select Tabs The output bus is selected by clicking on one of the tabs at the top of the console window. The above example shows the console window for AudioFire8.
Console Software 30 Console Software output bus tabs. AudioFire12 does not have S/PDIF, so it does not have a digital output bus; it has 6 analog output bus tabs instead. NOTE: Analog outputs 3 and 4 for the AudioFire2 are labeled as “Headphones” in the console.
Console Software 31 Console Software The input monitor controls are a little complicated. Basically, there is a different set of input monitor controls for each output bus , but only one set is visible and changeable at a time .
Console Software 32 Console Software The AudioFire8 Console Window: Analog Out 3-4 Tab selected. Note that since the Analog 3-4 tab is selected you are no longer looking at the input monitor and output controls for analog outputs 1 and 2. You are now looking at the controls for analog outputs 3 and 4.
Console Software 33 Console Software monitored between the two channels of the currently selected output bus. Holding the Ctrl key and clicking on a pan knob w ill set it to the center position. Below each pan knob is a non-selectable green field that tells you the current setting of the pan knob.
Console Software 34 Console Software Adjusting Playback Volume Output volume adjustments are m ade in the digital domain. When you lower a volume fader below 0dB, you are actually decreasing the number of available bits, thereby taking away from the potential dynami c range of the system .
Console Software 35 Console Software Settings Tab Clicking the “Settings” tab allows you to access settings for controlling your AudioFire hardware. The Settings page includes the sample rate, clock source, S/PDIF format and version information. The AudioFire8 Console Window: Analog Out 3-4 Tab selected.
Console Software 36 Console Software Sample Rate The sample rate for your AudioFire hardware is set here. The sample rate, also known as clock rate, affects recording a nd playback. For more information please refer to Appendix C: An Introduction to Digital Recording.
Console Software 37 Console Software The S/PDIF output defaults to the Consumer format. If you are recording from your AudioFire8 into a professional DAT deck, CD recorder, or Mini Disc recorder, the device may not be able to recognize the signal until you switch the output to Consumer.
Console Software 38 Console Software Console Settings and Stand-Alone Mode When the console is closed, all the cons ole mixer settings for your AudioFire are saved to flash memory in the AudioFire. So, these settings will be recalled when you reboot your AudioFire or move it to another computer.
Console Software 39 Console Software Synchronizing Multiple Devices Your AudioFire is designed to work alongside other audio equipment. If you are planning on using your AudioFire with other audio equ.
Console Software 40 Console Software Note: When synchronizing your AudioFire product to an external device via S/PDIF or Word Clock, you must set the AudioFire to the correct base clock rate. See the following table for th e correct base clock rate setting.
Console Software 41 Console Software Connecting to your computer You can connect multiple AudioFires to your computer by daisy chaining FireWire cables (connecting one AudioFire to the ne xt) or by connecting each AudioFire to a different FireWire connector on your co mputer.
Console Software 42 Console Software We recommend using a maximum of 3 Audi oFires on each FireWire bus. Multiple FireWire connectors that are on the sa me FireWire card are all on the same FireWire bus. Similarly, all the FireWire connectors that are directly on your motherboard are on the same FireWire bus.
