3. Installing the Xonar Hardware

3.1 Preparing Your Computer

Before you proceed with the following installation steps, it is recommended that you disable your onboard audio device in your BIOS settings, or uninstall any other sound cards on your PC. (For BIOS settings or uninstallation of other sound cards, refer to the user manuals of your motherboard and sound card.)

1. Power off your computer and disconnect the power cord.
2. Open the computer's case.
3. Remove the metal brackets from one unused PCI Express x1 slot for the audio card and its adjacent slot for the MIDI board (you can just remove one if you don't need to use the MIDI board in the package).

3.2 Installing the Audio Processing Card

1. Face the bracket of the Xonar D2X audio card toward the back panel of your computer and insert the audio card gently into an available PCI Express slot. Make sure it is completely inserted into the PCI Express slot. (Warning! Do not force the audio card into the slot. Make sure that the gold pins of the card's PCI Express connector are aligned with the motherboard's PCI Express connector before you insert the card into the PCI Express slot. If it does not fit properly, gently remove it and try again.)

1. Secure the audio card bracket to the back of your computer with the screw that you removed. Refer to section 3.1.
2. Connect the power cable of your power supply to the power connector on the Xonar D2X audio card.

The PCI Express high-quality audio card requires additional power from your computer. If the power cable is not connected properly, the audio card will not work at all.

When removing the power cable from the Xonar D2X audio card, make sure to pull outward the 4-pin header first, then unplug it from the power connector as the following pictures show. Do not forcefully remove the header from the power connector; doing so may pull up the power connector from the audio card and cause damage!

3.3 Installing the MIDI board

1. Secure the MIDI bracket to another slot on the back of your computer case.
2. Connect the 4-pin MIDI header on the audio card to the MIDI bracket with the MIDI cable as shown in the figure below.

3.4 Connecting CD/DVD-ROM Drive (with the analog header)

1. If you would like to use the physical playback buttons on your CD-ROM drive to control audio CD playback on your PC, you need to connect the analog cable between the CD-ROM drive and the audio card. Otherwise, you can skip this section and use ordinary digital CD playback on Windows.
2. Connect the CD-IN 4-pin header to the analog output on the back of your CD/DVD-ROM drive with the audio CD cable, which is usually included with the CD/DVD-ROM drive.

3.5 Connecting TV Tuner Card

1. If you have a traditional PCI or PCI Express TV tuner card on your PC, you may need to connect it to the audio card to send the tuner card's sound to your PC speakers.
2. Secure the PCI/PCI Express TV tuner card and screw it into the back-panel.
3. Connect the audio output header from the TV tuner card to the Aux-In header of the audio card, as shown in the figure below.

For optimum TV audio quality, Xonar uses ADC recording to digitize the signal and loops it back to DAC playback. Please select Aux-In as the recording source in the Xonar Audio Center's recording mixer and enable the monitoring button to pass this signal to the audio output. Using this setup, you can even turn on sound effects such as Pro-Logic IIx to expand the stereo TV audio to 5.1 or 7.1 channel surround sound. TV audio on your PC will become even better than on your TV set!

6.7 AEC (Acoustic Echo Cancellation)

Xonar D2X provides advanced Acoustic Echo Cancellation (AEC) for best voice communication quality over your speakers. AEC technology can eliminate up-to-40dB speaker echo return and suppress noises into your microphone for easier conversation experience. AEC is an innovative feature to make Xonar D2X the best sound card choice for online chatting in VOIP applications (Skype, MSN, Google, QQ, etc.) or online gaming. AEC provides the following benefits to you:

• Reduce voice acoustic echoes like speakerphone devices when others talk to you online.
• Minimize playback sound echoes into your microphone during gaming or music playback.
• Effectively suppress background or system noises into your microphone.
• 32-bit floating point algorithm providing precisely adaptive echo cancellation performance up to 40dB. Supports all VOIP applications and online games.

To achieve the best performance of AEC function, the ideal system requirements are as follows:

1. Speakers and microphone are low distortion (max. THD < 2%).
2. Flat frequency response between 300~4KHz.
3. Use omni-direction electret microphone with >=40dB sensitivity.
4. The microphone is more than 30cm far from PC's speakers (fix the distance) and do NOT turn your speakers too loud.
5. Put your microphone 20~30cm away from you (fix the distance) and do NOT speak too close or too loud into the microphone to avoid signal clipping and distortion. Enable "microphone boost" on Xonar D2X audio center mixer to get proper input signal level.
6. It's suggested to disable original AEC function residing in some of the softphones or voice communication programs to get best performance from Xonar D2X audio card.

AEC function will be only suitable for bi-direction voice communication applications. The speaker type will be set as 2 speakers and special voice processing mode while AEC is applied (all audio effects will be suspended and those controls on audio center will be frozen.). After you finish the voice-over-IP applications, please remember to turn it off for normal high-fidelity audio playback mode.

10. RMAA Test Guide

The Xonar D2X driver CD includes RightMark Audio Analyzer (RMAA) v5.6, a 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. 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 D2X audio card.

10.1 Setting Up Xonar D2X Audio Card

Open the Xonar D2X Audio Center. Use the settings below:

1. Select the sample rate you will be using with RMAA (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.

1. Go to the Mixer Recording page and select "ALT" as the recording source. 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 D2X audio card.

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.

1. Click "Reset" on the playback volume mixer page to keep the volume setting on default.
2. Turn the master volume to the MAX level (0dB).

10.2 Configuration and Test with RMAA

Start RMAA and follow the setup procedure below.

1. Select both of the playback/recording devices as "ASUS Xonar D2X Audio".
2. Select 24bit and 48KHz for the test signals. (If you change the format here, please remember to go back to set the same sample rate output in the Xonar D2X Audio Center.)

1. Click "Test options" button in RMAA and check "Analyze noise and distortion only in 20Hz-20KHz range" (audio in-band for human hearing) in the General tab.

1. Go to the Sound Card tab and select "DirectSound" as the Driver Model (because Windows MME mode doesn't support high-resolution 24bit audio playback and the data may be manipulated by Windows so that the real hardware quality cannot be measured properly.)

1. Click loop-back mode test button.

1. Check if the levels shown in the Adjusting level window are OK (the level meter will be green).

1. If the recording volume level is not high enough, please check and make the WAVE and Master Volume have been at the maximum level; instead, if the recording volume level is too high, please lower the WAVE and Master volumes gradually until the level is OK.

1. Begin the test by clicking the "Done" button. If you cannot get the level to be "OK" after the previous step, click "Done" anyway and proceed.

1. Enter "Xonar D2X Audio Card" in the New slot name and select one Empty slot. Then click "OK".

1. RMAA will pop up the Test results window. You can click the "Select" checkbox and click to "Make html report".

1. Check and key in the report name/options as follows and then click "OK".

10.3 RMAA Testing Results

Open the HTML file you created and saved in the test above, and it will display the report with both data and plots in your browser. The following report is a sample and you can see how high-fidelity and crystal-clean the Xonar D2X audio card is for both output and input (one of the world's finest sound cards, it has higher quality than most CE devices). You can also try testing the performance for other sample rates and bit-depths with the same procedure.

I can't hear any sound from the S/PDIF output

Instructions:

1. Ensure that you have enabled S/PDIF output in the Audio Center GUI (Main page).
2. Ensure that you are connecting the correct S/PDIF output jack on the card to the decoder's (AV receiver) S/PDIF input jack.
3. You may need to select the correct input and mode of your decoder or AV receiver. For Dolby Digital or DTS output, you may have to double check that the AV receiver is in that decoding mode.
4. If you are using 192KHz PCM output, please make sure your decoder can support 192KHz decoding. Try changing it to 44.1K or 48KHz first.

I can't hear audio input (Mic, Line-in, CD-in, etc.) from my speakers Instructions:

1. Go to the mixer recording page in the Audio Center and select the correct input as the recording source (Xonar D2X uses high-quality 118dB digital recording and monitoring to route the input signal through to the output.) If you are using Windows Vista, please also go to system audio control panel to see the current default recording/input device is right.
2. Remember to turn on the digital monitoring button for that recording source.

Q7: Does PMP software decrypt and violate the DRM of the copyright content? What's ALT technology in PMP software?

Answer:

No, PMP software is not able nor intended to decrypt DRMed content. It's just a software tool used to record the analog output signal from the line-out and then convert it into WMA and MP3 files. If you have Windows Media Player 10 or iTunes DRMed music, you are required to have the valid digital rights to play it, so that PMP can record it from analog output just as any other software recorders. Xonar D2X provides Analog Loopback transformation (ALT) technology to accelerate

the playback speed (2X, only on Windows XP) and record the accelerated analog signal. PMP will convert the signal back to the normal speed with very high-quality (118dB SNR), low distortion (-108dB) time-scaling algorithm. ALT technology can shorten the total conversion process. Please refer to the graph below:

Q8: What's the application of "S/PDIF in loopback"?

Answer:

"SPDIF in loopback" is the process of looping back the sound card's S/PDIF digital input signal directly to the S/PDIF output. It's useful mainly for two purposes:

• transforming electrical signals from coaxial cable to a fiber optical cable, or vice versa.
• using the PC as a SPDIF bridge (typically as a media center): for example, connect other devices like DVD players to the Xonar D2X's S/PDIF input and then connect its SPDIF output to an AV receiver or decoder. When you would like to send the player device's audio to the AV receiver, you need to have the Xonar sound card's "S/PDIF in loopback" enabled to redirect the player's input signal to output to the AV receiver.

Since "SPDIF In Loopback" is the hardware's high-fidelity pass-through path, not all sound effects will be applied to the signals.

Q9: Will PCM sound output through S/PDIF be just 2 channels even with different analog output channels?

Answer:

The S/PDIF protocol specification (IEC-60958) can only carry 2-channel PCM data or non-PCM AC3/DTS data. So, when a user selects PCM output for S/PDIF, the Xonar sound card will always deliver 2 channel PCM data through the S/PDIF output port. For attaining 5.1 channel surround sounds, you can select Dolby Digital Live or DTS Interactive encoding output from the S/PDIF out menu, which will allow the Xonar D2X to deliver 5.1 surround sound for games, DVD movies, and even stereo music.

Q10: Why is the sample rate of the original music file changed after the file is converted by PMP into a WMA file?

Answer:

The sample rate of a WMA file must be limited at 44.1KHz.

Q11: Why is the ALT recording volume reduced?

Answer:

If you connect a device, such as a headphone or speakers, the device will reduce the recording volume. When the situation happens, remove the device and try the function again.

Q12: Why is it that while playing audio CD, I cannot adjust volume from the path: Mixer page > Playback > CD?

Answer:

If you are using the Microsoft® Windows Media Player to play audio files, you have to change the playback setting of your CD optical drive to Analog. Open the Windows Media Player and do the following to change the setting: Tools > Options > Device > CD Properties > Playback > Analog.
