User manual M-AUDIO REVO71 F

[. . . ] . 29 Introduction Thank you for purchasing the Revolution 7. 1 by M-Audio. The Revolution 7. 1 is an audio upgrade for any PC or Macintosh computer, * bringing the ultimate in surround performance to your computer system. The Revolution 7. 1 brings you up to 24-bit, 192kHz audio and the highest-quality stereo, virtual surround, and multichannel surround sound available today. Please take the time to read this User Guide. [. . . ] By default, the front left and right speakers are highlighted. To change the settings of any other speaker, just click on that speaker in the diagram. Each speaker has it's own settings, so if you have large Front Left and Right speakers with a small Center speaker, you can set your system up accordingly. 18 Speaker Bass Management - This function enables Bass Management for the Revolution 7. 1 control panel. The Revolution 7. 1 control panel uses Bass Management to get the best sonic performance from your speakers. What this means is that if you have large speakers, it will send the full-range signal to those speakers. If you have small cube speakers, they probably can't reproduce the strong bass found in many DVD soundtracks, so the Revolution 7. 1 control panel automatically routes the bass from those speakers to the subwoofer. To allow a small-speaker surround sound system to reproduce the full-frequency spectrum by re-routing bass from the main channels to a subwoofer, which can handle frequencies that small speakers can not. As a precautionary safeguard to make sure the subwoofer is not overdriven when it simultaneously receives both LFE & Crossover Bass. Enable Bass Management by using your mouse to place a checkmark in the box, and use the Crossover control to select how much main-channel bass is sent to the subwoofer. Speaker Size - This setting tells the driver software what size your speakers are. Select the speaker size that best describes your selected speakers: Large, (5" or larger woofer), Medium (3"-5" woofer), or small (woofer smaller than 3"). The subwoofer screen, displayed after clicking on the subwoofer icon, has the following additional controls: Bass Boost - When Bass Management is turned on, this control increases the level of the Crossover bass signal to the subwoofer. This fader attenuates the bass below the crossover frequency sent to the subwoofer using Bass Management mode. LFE Boost - This controls the level of the ". 1" LFE signal going to the subwoofer. The subwoofer gets its signal from two places: from the LFE (". 1") signal on a DVD, and through bass management sending bass frequencies below a crossover frequencies to the subwoofer. These two faders give you individual control over these two signals. You can also adjust the overall subwoofer level using the Level control at the top of the window. Phase + 180 - This control switches the phase of the signal going to the subwoofer. Compare the volume of your subwoofer when this feature is enabled or disabled. Of the two settings, the one that produces the louder volume is the one you want to use. For example, if subwoofer volume is louder when Phase + 180 is enabled, then always leave this setting enabled. The best place for your subwoofer is usually near a wall or in a corner. Output Mixer Tab This tab provides level controls for each of the speaker outputs on the Revolution. [. . . ] With the proper settings, WinDVD will decode that material and send it to the multi-channel outputs of your Revolution 7. 1. To use WinDVD, you must have DirectX 8. 1 installed in your System. If you have an older version of DirectX, WinDVD will inform you that, "The setup program has detected that you have an older version of Microsoft's DirectX. " Click "Yes" to install DirectX 8. 1. If your System prompts you to restart your computer after installing DirectX, then do so. [. . . ]
