Set the center speaker between the front left and right speakers and no further from the listening position than the front speakers. • Consult the owner's manual for your subwoofer for advice on placing the subwoofer within the listening room. • If the surround speakers are direct-radiating (monopolar) then place them slightly behind and at an angle to the listening position and parallel to the walls at a position 60 to 90 centimeters (2 to 3 feet) above ear level at the prime listening position. • Connect the surround speakers to the surround speaker A terminals on the AVR-4806 and set settings on the setup menu to "A". (This is the factory default setting ( page 126).) • The surround speakers can be switched freely during playback with the surround parameter adjustment ( page 45). Surround Additional Information The AVR-4806 is equipped with a digital signal processing circuit that lets you play program sources in the surround mode to achieve the same sense of presence as in a movie theater. [1] Dolby Surround q Dolby Digital Dolby Digital is the multi-channel digital signal format developed by Dolby Laboratories. Dolby Digital consists of up to "5.1" channels - front left, front right, center, surround left, surround right, and an additional channel exclusively reserved for additional deep bass sound effects (the Low Frequency Effects - LFE - channel, also called the ".1" channel, containing bass frequencies of up to 120 Hz). Unlike the analog Dolby Pro Logic format, Dolby Digital's main channels can all contain full range sound information, from the lowest bass, up to the highest frequencies - 22 kHz. The signals within each channel are distinct from the others, allowing pinpoint sound imaging, and Dolby Digital offers tremendous dynamic range from the most powerful sound effects to the quietest, softest sounds, free from noise and distortion. 2 Dolby Digital and Dolby Pro Logic Comparison of home surround systems No. recorded channels (elements) Dolby Digital 5.1 ch Dolby Pro Logic 2 ch No. playback channels 5.1 ch 4 ch Playback channels (max.)
