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.

Philips Sound Solutions

3.2. Compact Control Panel

The Compact Control Panel contains the following controls:

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.

QSizzle

Toggles the QSizzle effect. When on, enhances the mid/high frequency range of a digitally compressed audio stream. The button label illuminates when QSizzle is enabled.

QRumble

Toggles the QRumble effect. When on, it enhances the low frequency range of the audio stream.

The button label illuminates when QRumble is enabled.

Normalize

Toggles Normalization (automatic volume leveling) on or off. The button label illuminates when

Normalization is enabled.

3D Effects

Toggles 3D Effects on or off. This does not affect 3D audio games, but does affect non-3D audio games utilizing the 2D to 3D remixing feature. The button label illuminates when 3D

Effects are enabled. To enable automatic audio features such as QSurround, and QXpander this feature must be enabled

EQ

Toggles the 10-band Equalizer on and off. The button label lights up when the Equalizer is enabled. When the button is not activated the EQ remains inoperative.

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.

11

Philips Sound Solutions

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).

12

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.

13

Philips Sound Solutions

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.

14

Philips Sound Solutions

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 preselected at Mic In. To record from Mic In, connect the Microphone and launch your favorite recording software and just hit Record.

15

Philips Sound Solutions

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.

16

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.

3.3.6. Info Tab

This tab contains useful information regarding the product. It includes the software driver’s version number, manufacturer’s name, and web page addresses.

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.

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”.
