ENGLISH Additional Information [2] When not using surround back speakers Front speakers Center speaker Monitor Subwoofer 60° 120° Surround speakers [ As seen from above ] Surround speaker Front speaker 2 to 3 feet [ As seen from the side ] • Set the front speakers with their front surfaces as flush with the TV or monitor screen as possible. 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 2 to 3 feet above ear level at the prime listening position. Surround The AVR-1906 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 Dolby Digital Dolby Pro Logic No. of recorded channels (elements) 5.1 ch 2 ch No. of playback channels 5.1 ch 4 ch Playback channels (max.)

Also refer to the player's operating instructions. Media Dolby Digital output terminals Playback method (reference page) LD (VDP) Coaxial Dolby Digital RF output terminal 1 Set the input mode to "AUTO" ( page 19, 20). DVD Optical or coaxial digital output (same as for PCM) 2 Set the input mode to "AUTO" ( page 19, 20). Others (satellite broadcasts, CATV, etc.) Optical or coaxial digital output (same as for PCM) Set the input mode to "AUTO" ( page 19, 20). 1: Please use a commercially available adapter when connecting the Dolby Digital RF output terminal of the LD player to the digital input terminal. Please refer to the instruction manual of the adapter when making connection. 2: Some DVD digital outputs have the function of switching the Dolby Digital signal output method between "bit stream" and "(convert to) PCM". When playing in Dolby Digital surround on the AVR-1906, switch the DVD player's output mode to "bit stream". In some cases players are equipped with both "bit stream + PCM" and "PCM only" digital outputs. In this case connect the "bit stream + PCM" terminals to the AVR-1906. w Dolby Pro Logic II • Dolby Pro Logic II is a new multi-channel playback format developed by Dolby Laboratories using feedback logic steering technology and offering improvements over conventional Dolby Pro Logic circuits. • Dolby Pro Logic II can be used to decode not only sources recorded in Dolby Surround ( ) but also regular stereo sources into five channels (front left, front right, center, surround left and surround right) to achieve surround sound. 54 ENGLISH
