[2] When not using surround back speakers

• 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 compatible media and playback

methods

Symbol indicating Dolby Digital compatibility:

The following are general examples. Also refer to the player’s

operating instructions.

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.
