• 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-1506 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.

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.
Media
LD (VDP)
DVD
Others
(satellite broadcasts,
CATV, etc.)
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.
Dolby Pro Logic 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-1506, switch the DVD player's
2 ch
output mode to "bit stream". In some cases players are
equipped with both "bit stream + PCM" and "PCM only"
4 ch digital outputs. In this case connect the "bit stream +
PCM" terminals to the AVR-1506.
