Resumen del manual


10, 2007 ASUS Xonar D2 Audio Card RMAA6.0.5 Test Guide V.1.1 The Xonar D2 driver CD includes RightMark Audio Analyzer (RMAA) v.5.6, popular software intended for testing the quality of audio equipment, be it a sound card, portable MP3 player, consumer CD/DVD player, or a speaker system. However, the latest RightMark Audio Analyzer v6.0.5 is available now. This document describes the test guideline with RMAA v6.0.5 and the complete test results by updated Xonar D2 driver package (8.17.20 or later), which improves RMAA MME test quality inherently limited by Windows to faithfully present Xonar D2’s hardware quality. The measurements are conducted by playing and recording test signals, and using frequency analysis algorithms. The following provides a step-by-step loop-back test guide for your Xonar D2 audio card. 1. Setting Up Xonar D2 Audio Card Open the Xonar D2 Audio Center. Use the settings below: 1. Select the sample rate you will be using with RMAA test (here we set 48KHz for testing 48KHz/24bit signals). 2. Set analog output to 2-speaker mode (to get rid of any channel processing over RMAA stereo signals in the driver) 3. Turn off all sound effects including Dolby, DTS, 7.1 speaker shifter, EQ, Environment, etc. A quick way to do so is to enable the “Hi-Fi mode” button in the Audio Center.

Click “Reset” to make sure the recording volume is on the default highest level (0dB). This is actually a high-quality onboard loop-back path from the Line-out directly to the Line-In. This allows you to get realistic output and input quality ratings for the Xonar D2 audio card. Copyright © ASUSTek Computer Inc. All Right Reserved. P.3 ASUS Xonar D2 Audio Card RMAA6.0.5 Test Guide V.1.1 4 Note: You may also choose to use an external 3.5mm line cable as follows (as short as possible) to connect the Front-Out jack to the Line-In jack for loop-back testing. In that case, please select “Line In” as the recording source on the mixer page. However, this external cable may cause unexpected performance drop depending on its cable quality. 3.5mm Line Cable Copyright © ASUSTek Computer Inc. All Right Reserved.

Please mind that Xonar D2 currently supports 44.1K, 48K, 96K, and 192KHz. 88.2K, 176.2KHz, and 32bit(float) tests are not supported.) 3. Click the General test options in RMAA and make sure “Analyze noise and distortion only in 20Hz-20KHz range” (audio in-band for human hearing) is selected. 1 2 4 5 3 4. It’s recommended by RMAA to ignore the two tests: “Frequency response (swept sine)” and “Total harmonic distortion (set of tones)”, which are for speaker test primarily. . 5.
