AVC-50 !IlkliSIND THE OHHOLIND SOUND PROCESSOR The AVC-50 incorporates a sophisticated. multi-mode surround sound processing amplifier which allows you to expand and shape the audio sound field with both audio and video sources, for a theater-like experience in the listening/v erring room. The AVC-50 surround sound processor has 5 processing modes, a defeat postion, and an independent delay time control which functions in conjunction with three of the surround modes. There are three modes for stereo audio sources. TAro modes for monaural audio sources are also included. The surround sound processor in the AVC-50 is effective only when the AVC-50 is used in a 4-speaker system setup. A Rear Speaker Placement The placement of a rear speaker pair in the listening room will greatly affect the overall sound field created. A small pair of speakers is all that is really required to create the full effect, and the most basic speaker placement configuration is the one shown in Fig. A. This setup is ideal for creating a theater-like atmosphere for movies and other video programs. The "6" setup creates a sound field with added depth, much like that experienced in a live concert hall, where all the sound is coming at you from the front. It is most appropriate for musical sources, rather than videos. The "C" speaker placement configuration effectively 'Widens" the sound field, and is suitable for movies and other video programs. While the most basic speaker placement setup is recommended at first, by experimenting with different speaker placements for each musical or video source, and with each surround sound mode, you will be able to create a wide variety of sound field effects suited to your listening environment, and to your own particular tastes. C 44, 4, TV LJ illy WJ Standard Positioning 18 When four speakers are placed to the front, a satisfactory effect will be achieved in situations in which the walls are board or concrete if the speakers are faced towards the wall, reversing the positioning as shown in this diagram. Where the speakers are placed to the left and right, a satisfactory effect will be achieved if the sub-speakers are slightly raised and pointing down.
