DOLBY PRO LOGIC
Dolby Pro Logic
This state of the art Dolby Pro Logic mini system enables you to experience and enjoy a Home Cinema sound ambience. Dolby Pro Logic is a coding system that enables a set to decode 4 sound channels out of a normal stereo signal: the center channel for picture related sounds, both front left and right channels for stereo sounds and one surround channel for the rear to bring room and depth to the scene. The surround signal is reproduced by two speakers placed towards the rear of the listening area. Although the surround signal is mono, a pair of speakers is necessary to produce the correct diffused sound field. Dolby Pro Logic manufactured under license from Dolby Laboratories Licensing Corporation. DOLBY, the double-D symbol d and �PRO LOGIC� are trademarks of Dolby Laboratories Licensing Corporation. General hints for speaker positioning Avoid positioning the speakers in a corner or on the floor, as this will boost the bass tones too much. Placing the speakers behind curtains, furniture etc. will reduce the treble response, thus reducing the stereo effect considerably. The listener should always be able to �see� the speakers. Each room has different acoustic characteristics and the positioning possibilities are often limited. You can find the best position for your speakers by following the picture on the right. The speakers should always be arranged as symmetrically as possible in the room.
