The label Normalization Active appears in illuminated text when Normalization is enabled, and Normalization Off when disabled. 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 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. 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. 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 panel can also collectively center the sliders. Please note that the default button resets several other features as well. 3.3.3. Setup Tab Speaker Test Utility The Speaker Test Utility can be used to verify that speakers and/or headphones are operating properly. The test utility highlights each speaker that is being tested. See Figure 8. Click any speaker icon to send the test sound to the corresponding speaker. If headphones are plugged in, the speaker icons are grayed out and you can click the left or right headphone icon instead. 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 or headphone icon. The Auto button sends the test sound to each output once and then moves to the next one automatically. If the Loop and the Auto buttons are used in conjunction, the test signal will loop through the available outputs 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. Subwoofer Slider The Subwoofer Level control enables you to set the level of the derived Subwoofer output relative to the left and right speakers. Balance Slider This slider allows you to adjust the balance between left and the right speakers or headphones. For best 3D effects it should normally be left in the center. Right-click the slider to center it. 3.3.4. Mixer Tab The Mixer Tab allows you to control playback and recording sources. Two sub-tabs at the bottom of the Mixer screen provide access to Playback or Recording controls. 3.3.4.1. Source controls When the Playback Sub-tab is selected, you can individually mute or un-mute as many playback sources as you wish using the Mute buttons. When the Recording Sub-tab is selected, you must select the single source you wish to record by clicking its Select button. See Figure 9. Volume sliders set the 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, the default position. Right-click any of the balance sliders to center it. 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. 3.3.5. 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. The Preset system enables you to save the state of PSA2 controls once you have made adjustmen...
