[. . . ] This is sufficient for creating 3D effects as the focus of attention is at the front, on the screen. To enhance the 3D impression, the sound from the rear loudspeakers is delayed by about 20 milliseconds. You don't have enough room to turn your living room into a home cinema?The five speakers would bother you, not to mention the cables they require? [. . . ] DSPpro will first perform a self test and is ready for operation after approx. To switch DSPpro off, press the POWER button for about 2 ­ 3 seconds. If pressed momentarily when DSPpro is switched on, it can also control the brightness of the DSPpro LEDs. You can choose successively between three brightness levels: dim, medium, and bright. The second headphone output provides the same audio signal, so a second user would listen with the same "ear type". If two persons are using DSPpro, you 30 Store two separate settings (see "Storing your personal ear type") and take turns at listening with your respective ear type. The headphone sockets have an additional function: In loudspeaker mode (the LED beside the button with the headphone symbol is not lit), the sockets deliver the four Dolby Surround channels. With the supplied adaptor cables, the Dolby Surround signals can be fed to external amplifiers. Of course you should try out DSPpro and its controls and functions as you please, but listen to some recommended settings first. Using RESET you can always reset DSPpro to the factory-adjusted standard settings. DSPpro will also return into the standard settings when it is switched off and on again.

Example: Volume At maximum volume the top LED will be lit, at minimum volume the bottom LED will light up. TEST enables you to check whether the virtual speakers that DSPpro creates are "positioned" correctly. When pressing TEST, a short hissing pulse is sent to one of the virtual speakers, when pressing again, to another speaker and so on. With PHANTOM you can compare virtual surround sound and normal stereo headphone sound. If PHANTOM is not active (LED is off) all signal processing (Dolby decoder and Toltec processor) is switched off, and the headphone reproduces the normal stereo audio signal. DSPpro features three controls for tailoring the sound to your personal listening preferences. In middle position (middle LED of the arc is lit) the bass response is neutral, it becomes less to the left and increases to the right. With BALANCE you can compensate for volume differences between left and right headphone system which may occur during transmission. If you are using Sennheiser headphones you will not need this control. [. . . ] After processing, the digital signals are converted back to analogue, the headphone reproduces the audio signal. A phenomenon whereby a given sound is assigned the direction from which it is first heard. Pro-Logic increases the differences in volume between the individual audio channels and is able to perform a better analysis of the directional information contained in the audio signal. It thus provides a better channel separation than the passive Dolby Surround system. [. . . ]
