1. Introduction
The Philips Sound Agent 2 (PSA2) is a computer graphical audio control center, designed to
work with Philips DGX220 Bus Powered Speaker. The PSA2 utilizes the computing power of
any compatible personal computer to enhance the quality of the audio that is played by PC
resident audio players. PSA2 includes a full suite of studio quality audio DSP processor that
adds features, depth and richness to all audio sources.
1.1. KEY FEATURES
QSurround enhances Dolby Digital 6-channel sources by filling the sound gap
between speakers to create a complete 360-degree wrap-around audio experience
that is smooth and natural. But more importantly, it creates virtual 3D surround over
a two-speaker setup.
Active Dynamic Filtering found in the new QSizzle and QRumble components
feature low, mid and high frequency enrichment algorithms that help restore sonic
fidelity for highly compressed digital audio files such as MP3s and WMAs. Simply
put, it makes MP3’s sound great.
UltraBass is a bass-enhancement system, which uses the way humans perceived
sound and signal processing to enhance bass quality of small loudspeakers.
QInteractive3D technology offers precise 3D sound positioning with headphone and
speaker output and is compatible with DirectSound3D, EAX 1.0, EAX 2.0/I3D Level 2,
and A3D enabled games.
QXpander converts ANY ordinary stereo input to virtual 3D surround sound with
headphones or speakers.
Professional style 10-Band Equalizer for precise sound tailoring of all digital audio
media.
15 unique reverb environments using the exclusive QSound Environmental
Modeling (QEM) algorithms for totally immersive gaming and dramatic musical
performances.
Normalization smoothes out the volume differences within audio files and reduces
the volume variations for all audio sources - automatically.
Default and user defined Presets for most settings to personalize all your games,
music, and movies - exactly the way you like it.

3. The Philips Sound Agent 2 Interface Operation
The following sections provide a detail description of the PSA2 features.
3.1. Launching the PSA2
DGX220 must be connected to the PC through the USB port. When DGX220 is not connected
to the PC, PSA2 icon in the system tray will appear with the red void mark. See Figure 2.
Sound Agent 2 icon
Figure 2
To open the control panel, double click on the PSA2 icon in the System Tray (normally the lower
right hand corner of the screen). This method can be used only if the icon does not have red
void mark on it. See Figure 3.
Figure 3
When you first launch the PSA2 it appears as partially expanded form as shown in Figure 4. To
reveal the Main Control Panel click on the Drop-down arrow at the bottom side of the
Visualization Control Panel.
The panel contains three distinct sections: Compact Control Panel, Main Control Panel and
Visualization Control Panel. To reduce the expanded form to a compact form, use the Resize
button. The Compact Control Panel takes up very little space on the screen and it contains the
top-level controls. However, to set or change some of the settings, you need to expand to the
Main Control Panel. Use the Resize button when you need to expand the Main control panel
again.

3.2. Compact Control Panel
The Compact Control Panel contains the following controls:
Mute Button Resize Button Close Button
Figure 5
Master Volume
Master Volume controls the overall output level of the sound system. This volume control is
synchronized with the volume control on the system tray (the yellow speaker icon).
Mute
This button toggles the sound on or off to attached speakers or headphones. It mutes the sound
but does not stop the player.
Resize
Resize button toggles between the compact mode (basic controls) and the expanded mode (for
more advanced options).
Close
Closes the PSA2 control panel without affecting audio operation.
Default
Pushing the Default button resets most controls to a predefined functional state.
Help
This button launches the on-line help system. It contains detail descriptions of all features of the
PSA2 interface and its operation.
Reverb
This button toggles the QSound Environmental Modeling (QEM) on or off. However, some
games apply their own environmental effects, which are not controlled by this button.
Environmental modeling uses reverb (reflected sound) and delay to create the impression that
the listener is in a particular environment.
QEM provides a wide range of high-quality environmental modeling effects that are selectable
from the Visualization Control Panel. By selecting a default environment, you impose
the
effects of that environment for music, movies, or games that do not use the EAX feature.
PSA2 responds automatically to games that use the EAX and EAX2.0 commands. These
games automatically control the selection of environments (regardless of what is selected from
the Visualization Control Panel) to match various scenes and locations, and change these
selections as the environment changes. The applied intensity of reverb is controllable by a slider
in the Visualization Control Panel. If the level of Reverb is not as expected, check the slider in
the Visualization Control Panel and adjust properly.

3.3. Main Control Panel
The Main Control Panel is in the center of the expanded mode, and it provides access to
advanced settings for most PSA2 controls, which are grouped in five separate tabs. See
Figure 6.
If only the Compact Control Panel is visible, you must expand it by clicking on the Resize button
on the right hand corner, next to the Close icon. See Figure 5.
If the Visualization Control Panel is covering the Main Control Panel, slide the Visualization
Control Panel cover down to reveal the Main Control Panel by clicking on the arrow at the
middle of the lower edge of the Visualization Control Panel. See Figure 4.
Figure 6
Once the Main Control Panel is open, you can choose any of the tabs to select the desired set
of controls. The following is a description of each tab from left to right:
3.3.1. Effects Tab
The Effects Tab is the first of the Main Control Panel tabs. Below is a description of all the
features on the Effects tab.
QSizzle
QSizzle is a mid and high frequency (treble) enhancement algorithm that helps to compensate
for the loss of presence, punch and signal detail that often results from compressed digital
media, such as MP3 and WMA formats.
QSizzle self-adjusts in real time according to frequency response of the input signal. This is
different from the Equalizer, which is a fixed frequency processor. The Equalizer does not
monitor the input signal or perform self-adjustment. The label QSizzle Active appears in
illuminated text when QSizzle is enabled, and QSizzle Off when disabled.

QRumble
QRumble is a powerful low frequency enhancement algorithm that helps to compensate for loss
of bass that may result from compressed digital media such as MP3’s or WMA formats.
QRumble responds in real time to the varying nature of the input signal, automatically adjusting
itself accordingly. This is very different from the Equalizer, which is a static frequency processor.
The Equalizer does not monitor the input signal or perform self-adjustment.
The label QRumble Active appears in illuminated text when QRumble is enabled, and
QRumble Off when disabled.
Normalization
Normalization automatically adjusts the volume variations in various audio files or streams.
Quieter signals are amplified to match the level of louder ones, so that the listening volume
maintains a consistent level. This means that when playing files with various output levels, the
need to constantly adjust your speaker volume is minimized.
The label Normalization Active appears in illuminated text when Normalization is enabled, and
Normalization Off when disabled.
NOTE: If the pre-recorded volume of the source is too high, the playback might sounds ‘wavy’.
This is ‘as designed’ and can be minimized by turning off the Normalization for that particular
song.
UltraBass
UltraBass is a bass-enhancement system, which uses the way humans perceived sound and
signal processing to enhance bass quality of small loudspeakers.
3D Effects
Three separate 3D audio enhancement algorithms are provided to maximize the spatial
experience no matter what the combination of signal type and output hardware.
When 3D Effects are enabled, the audio processor will automatically choose the appropriate
algorithm (3D mode) according to your output configuration and the type of input signal. The 3D
Effects indicator LED’s on front panel and the indicators on the Effects Tab illuminate to show
which algorithm is active at any given time.
QXpander optimizes stereo input played over 2 speakers or headphones. When QXpander is
active it provides a wider sound field far exceeding physical position of the speakers.
QSurround optimizes a multi-channel source (e.g. a 5.1 channel DVD) to create “virtual”
speakers and immerse the listener in surround sound.
NOTE: The source must be a multi-channel in order for this feature to be activated (e.g. on 5.1
DVD playback, please make sure the software-DVD player is set to 6-channel output).
background
Philips Sound Solutions

3.3.2. Equalizer Tab
The Equalizer (EQ) controls the frequency response of the system by increasing or decreasing
the frequency response of ten independent frequency bands.
This Equalizer works very much the same as the equalizers in high quality sound systems. Each
slider controls the relative level of a band (range) of frequencies. The number listed above each
slider column is the center frequency of the band controlled by that slider. When a slider is set to
the center position, frequencies within this band left flat and the gain is 0dB. See Figure 7.
Figure 7
To boost the level of a given band, move its slider above the centerline. To cut the relative level
of a given band, move its slider below the centerline. Maximum boost or cut is ±12dB on each
frequency level.
Sliders can be individually centered by right clicking anywhere within the slider area, or
collectively by clicking the Reset button on top right corner of the panel. Clicking the default
button on the Compact Control Panel can also collectively center the sliders. Please note that
the default button resets several other features as well.

3.3.3. Setup Tab
Figure 8
Speaker Test Utility
The Speaker Test Utility can be used for troubleshooting, in case no sound is coming out of the
speakers when expecting to have sound.
The test utility highlights each speaker that is being tested. Click either speaker to send the test
sound to the corresponding speaker. See Figure 8.
The Loop test button allows the test to repeat until the Stop button is pressed. If the Loop is off,
the sound will play once for each click of a speaker button.
The Auto button sends the test sound to each speaker once and moves to the next speaker
automatically. If the Loop and the Auto buttons are used in conjunction, the test signal will loop
through the speakers until the Stop button is pressed.
Preamp Slider
The Preamp Level control allows you to boost the input audio signal before it is processed by
the PSA2. It has a similar effect as the master volume, but should not be used instead of it.
NOTE: Increasing the PreAmp may cause audio distortion on some high level input signals. In
some cases, an input signal can be of such amplitude that audio distortion can occur at the
preamp default level. If this is the case simply lower the preamp level to help eliminate any
distortion.
Balance Slider
This slider allows you to balance the left and the right speakers.

3.3.4. Mixer Tab
Mixer controls allow you to control playback sources.
3.3.4.1. Playback source controls
You can individually mute or un-mute as many playback sources as you wish.
Volume sliders set the playback level for each source.
Balance sliders adjust the relative left and right output levels for each stereo source. Balance
sliders should normally be left in the center, which is the default position. Right-click any of the
balance sliders to center it.
Depending on the number of available playback sources in your PC, the number of horizontal
and vertical slider may vary, and a scrollbar may or may not be preset. The viewing area on the
Mixer Tab displays controls for a maximum of four playback sources at one time. Use the
Playback Source Scrollbar (if present) to reveal more source controls. See Figure 9.
Figure 9
When playing audio CD’s using the CD ROM driver of the PC, one should enable the digital
audio extraction in the system device manager. If you need more information refer to the
TroubleShooting section in Appendix C of this document.
3.3.4.2. Recording source controls
To simplify the operation of recording control on PSA2, the recording source have been pre-
selected at Mic In. To record from Mic In, connect the Microphone and launch your favorite
recording software and just hit Record.

3.3.5. Presets Tab
The Preset functions enable you to make snapshots of the state of all Philips Sound Agent 2
controls, so that you can conveniently reload the same settings at any time.
Figure 10
The Preset system enables you to save the state of PSA2 controls once you have made
adjustments to customize your listening experience, so you can recall settings for any source
and playback environment.
For example, if you have been listening to music with predominant drums and bass and have
adjusted the controls to suit your taste, you can quickly save a preset called “Drums’n’Bass”.
Whenever you listen to this type of music again, simply load this preset, and all the controls will
return to the settings you had in effect when you saved it.
Sound Agent 2 comes with six factory presets as listed on the Presets tab. The following is a
description of each feature on the Presets tab.
background
Philips Sound Solutions

Load
Clicking on this button loads an existing preset. To load another preset, highlight it on the list
and click the Load.
Save
When you load one of your presets and make changes to it, you can save it by clicking on the
Save button. If you have selected one of the factory presets and made changes to it, you will
have to save it under a different name. Sound Agent 2 will not overwrite factory presets, but
you can overwrite your own unique presets.
Save As
You can load an existing preset (factory or one of yours), modify it to your taste, and save it as a
new preset.
Delete
Deletes the selected preset permanently from the list. When you select one of your presets and
click on this button, a confirmation dialog box will appear and when you confirm by clicking the
OK button, the preset will be removed from the list. This button will not delete any of the factory
presets.

6. Appendix B, USB Hub Considerations
6.1. Introduction to USB Hub
A hub is a USB device that uses one USB port for connection to a PC and typically provides
four additional ports for connection to USB devices. The function is similar to an electrical plug
expander or an extension cord with multiple receptacles.
Some of the earlier computers have only two USB ports that are usually located on the backside
of the computer. In this case if we have more than two USB devices for connection to the PC we
need to use a USB hub. Using a hub not only provides more USB ports, but also provides easy
access to the ports that are located in the back of the computer.
Most newer computers have two USB ports in the back and two additional ports in the front. The
front ports are usually concealed under a flip up or flip down cover. Refer to your PC document
to locate these ports.
A USB host controller card may be added to a computer if it does not have any USB ports at all.
These cards need to be installed inside the computer in a PCI slot.
6.1.1. Power Limitation
Hubs, like any USB device, may be bus-powered or self-powered. A self-powered hub has an
external power supply, which plugs into an electrical outlet, and can provide maximum specified
power to all its USB ports. A bus-powered hub draws power from the root USB port, and thus, it
has limited power available to the connecting USB devices.
6.1.2. Bandwidth Limitation Issues
Each USB port on the PC has a maximum bandwidth of 12 Mega-bits per second (Mbps).
Different USB devices require different amount of bandwidth. Connecting more than two high
bandwidth-demanding devices to a hub may cause degradation of functionality for some or all of
the devices on that hub. For example, connecting a web camera and an audio device to the
same hub may cause gaps in the displayed video, or gaps in the audio stream. It may even
cause the devices not to function at all. This usually happens to the device that is used last
when other USB devices are active.

7. Appendix C, Troubleshooting
9 No Sound is coming out
1. Ensure the speaker system is plugged in.
2. Check the mute button to ensure it is deactivated.
3. Check the volume button and turn it up.
4. Click on default button on the PSA2 Compact Control Panel.
9 System Error Message
When attempting to launch an audio player application, on a rare occasion you may see one of
the following error messages depending on the operating system of the PC. This error message
also causes no audio to be played.
Windows XP
Windows 2000
Figure 13
This error message is generated due to lack of sufficient bandwidth on the USB hub that the
Audio System is plugged into. If you have a USB imaging device (such as a webcam or a
scanner) and you have an imaging application open, and try to open an audio player application
such as Winamp or Windows Media Player.
Solution
Click “Close” or “No” depending of which error message you have.
Close the audio player application.
Close the imaging application.
Reopen the audio player application and play the audio stream.

9 CD Player Control in the mixer playback tab does not have any effects on
the output when Playing Audio CD in the CD Drive
Because the CD player sends the audio streams via the digital data lines, Windows treats this
source like other digital audio sources such as MP3 files. Therefore, to control the volume and
balance use the controls for “wave”.
9 No PSA2 Icon in the System Tray
After you have installed PSA2 from the installation CD, if the PSA2 icon disappears from the
System Tray, go to the start menu, click on Programs (Windows 2000 or Windows XP), click on
Philips, then click on Sound Agent 2, then click on Control Panel.
