Introduction
As Vista OS brought users a newer interface, Realtek’s new Vista GUI provides users a more
convenient access for audio appreciation. This page will show you a quick glance with brief
note of major features and applications comprised by a sense of area allocation of the GUI.
I. Jack and Device: This area depicts all render and capture devices currently
connected w/ your PC; the “check” sign (in orange) indicates the devices as default
input/output setting. Additionally, more applications would be found at the option of
“Device Advanced Settings”.
II. Application Enhancement: The array of options will provide you a complete
guidance of anticipated sound effect for both output and input device.
III. Information: Showing hardware, software information, and language setting.

1. Jack and Device
All audio functions start with a correct device connection and Realtek HD Audio Manager
facilitates users with a series of friendly interface to ensure the device is connected. You may
figure out more tips with a demonstrated example below:
Example: How to Successfully Connect a Microphone
Step I: When you plug into the microphone at the pink jack of front panel, a dialogue window
will pop up asking you which device is current connected. As you know, each jack corresponds
to its default setting, and the pink jack represents “Mic In”.

Step II: When you confirm it’s OK, a new device will be included in the Device area (upper of
the screen), which you could compare the previous figure and the one below.
Step III: Once the process is completed, you may click the pink jack of the front panel, the
Microphone page will pop up afterwards. Showing the connectivity is successfully
implemented.

When you click the icon, namely, the yellow flag on the upper right of the screen, it will pop up
a dialogue window asking users their preference when system detects a device is plugged in.
Set Default Device
When more than 2 playback device plugged in, e.g. Digital output and Speaker, users need to
choose one and set it as default device. Same situation applies to the recording device.
Regarding how to set default device, please refer to P45 “What Is Default Device”.
Figure 1.1-1 Set Default Device
Realtek HD Audio Manager 8

Device Advanced Settings
The advanced setting provides the mechanism to deal with 2 independent audio streams.
Assuming that 2 devices already plugged in, say, a set of stereo speakers and headphone,
and you are about to use the speaker for a movie while using the headphone for the latest hit.
Select “ Make front and rear output devices playback 2 different audio streams” after you click
the device advanced settings with a pop up window.
Choose speaker and set it as default device.
Initiate any application program, e.g. media player, to playback the content.

2.1. Speaker Configuration
Realtek Audio facilitates users to best enjoy the listening appreciation with your available
equipments. We provide speaker settings spanning from 7.1channel, 5.1channel,
Quadraphonic (4 channel), stereo (2 channel). The following are two common scenarios.
Example I : 7.1ch. Speaker Set for Home Theater
Figure 2.1-1 7.1 Speaker Setup
Assuming you are building your home theater system with 7.1ch speaker set. Once you have
bought the speaker set with Realtek audio codec inside, you may follow the procedures to
correctly enable the speaker configuration.
Step I: Plug in the device in any available jack. Preferably at the default setting; e.g. the
default setting of the front speaker is the green jack of the rear panel.
Step II: A Dialogue Window of “The current connected device” will pop up for your selection.
You may click OK once you confirm it is an appropriate setting.
Step III: A useful check out icon (with circle above) is designed to help you hear and verify
Realtek HD Audio Manager 11
2. Application Enhancement
the sound exactly from the designated speakers.
Additional Applications
Speaker Fill
Definition: Speaker Fill creates a virtual environment for playback of stereo audio sources
on surround speaker systems
Example: When you playback a MP3, and you will hear sound appear from every
speaker of a 7.1ch set once you enable the speaker fill
Swap center/subwoofer speakers
Definition: It is an option to make low frequency sound playback from subwoofer. Users
do not need to check this item if low frequency sound is from subwoofer already.
Bass Management
Definition: Bass Management enhances or redirects frequencies below crossover point
to reduce loss or distortion of bass signals. It will facilitate users to obtain the best bass
enjoyment.
Full Range Speaker
Definition: This is a reminder for users to confirm the speaker system is full or small
range, for small range speakers can’t output full frequency audio streams.
Optional Speakers
Definition: The default setting is to assume users equip with subwoofer with their 7.1ch
speaker set, that’s why you could see with a check sign. However, if users don’t have
subwoofer, we need to blank the option and suggested to enable bass management to
make sure low frequency audio streams will be playback.

2. Application Enhancement
Example II: Stereo Speaker Set Figure 2.1-2 Stereo Speaker Setup
Assuming that a set of front speakers with your Desktop at the study room is what you have.
You may follow the procedure to correctly enable the speaker configuration.
Step I: Plug in the device in any available jack. Preferably at the default setting; e.g. the
default setting of the front speaker is the green jack of the rear panel.
Step II: A Dialogue Window of “The current connected device” will pop up for your selection.
You may click OK once you confirm it is an appropriate setting.
Step III: A useful check out icon (highlight in yellow) is allocated at the bottom of the screen.
When you click it, you should be able to hear the sound exactly from the speakers.
Additional Application
Headphone Virtualization
Definition: Headphone Virtualization uses advanced processing to create the illusion of a
home theater while using stereo headphone.
Example: When you use a normal headphone to listen MP3, this option will provide a
surround quality music.
Virtual Surround
Definition: Virtual Surround encodes surround audio for transfer as stereo output to
receivers with a Matrix decoder.
Example: It will be beneficial for users to enjoy a surround sound with only stereo
speakers

Movie mode
The movie mode is for use with stereo television shows and all programs encoded in Dolby
Surround. The result is enhanced soundfield directionality that approaches the quality of
discrete 5.1-channel sound
Music mode
The music mode is for use with any stereo music recordings, and provides a wide and deep
sound space. The Music mode includes controls that allow the sound to be tailored to
individual listening tastes.
Panorama control
This extends the front stereo image to include the surround speakers for an exciting
“wraparound” effect with side-wall imaging. It is particularly effective for recordings which
have left- or right- channel elements in the mix, as these are detected and accentuated
by the Panorama process.
Dimension control
This allows the user to gradually adjust the soundfield either towards the front or the rear.
This can be useful to help achieve the desired balance from all the speakers with certain
recordings that may contain either too much or too little special effect. Step “0” is the
recommended setting, which has no effect on the sound. Step 1, 2 and 3 gradually move
Realtek HD Audio Manager 29
2. Application Enhancement
sound forward, and steps –1, –2, and –3 move the sound toward the surround.
Center Width control
This allows center-channel sound to be positioned between center speaker and left/right
speakers over a range of eight steps. Step “3” uses a combination of all three front
speakers to give the best vocal imaging and most seamless soundstage presentation,
and is recommended for most recordings. Step “0” places all center sound in the center
speaker. Step “7” places all center sound equally in the left/right speakers, just as in
conventional stereo.
All three of the above controls may be used alone or in any combination. It is recommended
that you try them on a few programs. After try, it is easier to find the settings that are
preferable.
