[. . . ] This is useful when checking for driver updates on the M-Audio website, or in the event that you need to call tech support and give them your system information. 12 Windows Sound System and the Audiophile USB Windows may be set up to use the Audiophile as its default audio device, allowing system sounds to be played through the Audiophile. This also enables you to use the Audiophile with the sound applets included with Windows. To set this up, go to Control Panel | Sounds and Audio Devices (or, "Multimedia" in Windows 98). In the Audio Properties page, set the Playback and Recording devices to the Audiophile USB input and output devices of your choice. Windows may also use the Audiophile USB as its default MIDI device. This allows the Audiophile USB to be used with the MIDI applications included with Windows. To set this up, go to Control Panel | Sounds and Audio Devices | Audio. (Or, go to Control Panel | Multimedia | MIDI in Windows 98. ) Set the Audiophile MIDI driver as the default Windows MIDI driver by clicking on the "Out USB Audiophile" entry in the drop-down list, then selecting "OK" or "Apply". Macintosh Sound Manager and the Audiophile USB The Macintosh Sound Manager will allow you to select the Audiophile USB as the system's audio input and output device. Open the Apple menu and select "Sound" from the Control Panels list. Then choose Audiophile as both input and output driver. However, you may also leave the Sound control panel set to "Built-in" if you wish to use the Audiophile only with your music program and use the internal audio for system sounds. Audiophile USB Inputs & Outputs The Audiophile USB Digital Recording Interface's analog inputs and outputs are compatible with a variety of audio products. The Audiophile USB has both female RCA and female 1/4" TS (tip-sleeve) input jacks, and female RCA output jacks. These jacks allow connection to unbalanced (typically consumer or semi-pro) line level equipment. Only one pair of analog inputs can be used at any given time. When a 1/4" TS plug is connected to the 1/4" line inputs, the corresponding RCA input jack is defeated. If you have RCA cables connected to the Audiophile and then connect 1/4" plugs to the 1/4" jacks, the Audiophile will then get its signal from the 1/4" line inputs. NOTE: In order to preserve its high dynamic range and minimize distortion, the Audiophile USB does not have microphone preamplifiers built into it. Therefore, directly connecting a 13 microphone is not recommended. Instead, pass the microphone signal through a microphone pre-amp (such as the M-Audio TAMPATM, DMP3TM, or Audio BuddyTM), and then connect the pre-amp output to the input of the Audiophile USB. Some additional cable and/or cable adaptors may also be needed to ensure proper connectivity. The Audiophile USB also has digital inputs and outputs in S/PDIF format. These are available on RCA connectors, as stereo pairs. These jacks receive or transmit a digital audio stream that is independent of the analog audio streams. However, because of the bandwidth limits of USB there can be a tradeoff between the number of inputs and outputs that are active and the sampling rate and bit depth of the audio being processed. Also, you should ONLY activate the S/PDIF Input if you are connecting an active digital audio device to this input. This is detailed in the previous section, "The Audiophile USB Control Panel. " Also detailed in the previous section is the use of the S/PDIF Output for sending encoded surround sound signals. Checking the "DD/DTS Pass-Thru" box in the Audiophile USB Control Panel will allow you send Dolby Digital, Dolby Surround, DTS, or any encoded surround sound signal to the S/PDIF Output of the Audiophile USB. You can connect this output to a home theater system, or any device that will decode this signal. Using most DVD players, select the "S/PDIF" option in the DVD players audio setup page, and your computer becomes a high-end home theater player in conjunction with the Audiophile USB. Audiophile USB with Your Music Software Once the Audiophile USB hardware and software drivers are properly installed, the Audiophile is ready for use with your music application software. Some software applications may require you to highlight or enable the Audiophile USB drivers within the program in order to use the Audiophile, while others may have a utility that analyzes or profiles the audio devices in your system and enables the drivers. Your software should have an audio device driver setup page. [. . . ] This update will be skipped if you already have DirectX version 8. 1 (or higher) in your system. 1. During this installation, the Audiophile USB must be powered off. Begin the installation process by inserting the Drivers CD ROM in your computer. and double-click on the Audiophile USB.
