About the “VIRTUAL MATRIX 6.1” playback

(For STR-DB1070) You can reproduce the 6.1 channel surround sound of the sources encoded in 6.1 channel (see below) in the 5.1 channel speaker settings.

(For STR-DB870) Though this receiver incorporates the 5.1 channel amplifier, you can reproduce the 6.1 channel surround sound of the sources encoded in 6.1 channel (see below).

To enjoy the “VIRTUAL MATRIX 6.1” playback most effectively, use the 6.1CH DECODING function when you select “CINEMA STUDIO EX A–C” or “SEMI CINEMA STUDIO EX A–C”. The sound characteristics of CINEMA STUDIO and the 3D sound imaging create the virtual surround back speaker, and you can enjoy the surround effect as if in the real theater. You can select AUTO/ON/OFF using the 6.1CH DECODING button (page 45).

About 6.1 channel matrix decoding

Some movies released after summer 1999 added a new channel to the preexisting 5.1 channels. The new channel added speakers behind the listening position. In the movie theaters, these speakers are placed on the rear wall, on each side of the projection room’s window.

The 6.1 channel system used in the movie theaters is called Dolby Surround EX system. However, to record on movie film, this 6.1 channel is converted to

5.1channel using matrix encoding, and the same number of channels are used as Dolby Digital and DTS recordings. Recordings on DVD also use the same signals.

A lot of movie theaters screen movies with matrix encoded 5.1 channel signals and this is not unnatural to the ears. However, when a matrix decoder is used to create surround back speaker signals it simulates the same 6.1 channel sound as Dolby Surround EX system in the movie theaters.

This unit is equipped with a matrix decoder allowing for 6.1 channel sound production.

For STR-DB870, with Virtual 3D technology, the surround back signals can be enjoyed even without an actual surround back speaker. When the center speaker is not used, it is possible to use this channel to output surround back signals.

NIGHT MODE

Allows you to retain a theater like environment, at low volume levels even late at night. Even at a low volume level, you can clearly hear the dialogues and adjust the volume in small steps. This function can be used with other sound field (pages 28–30).

While this function is on, BASS, TREBLE, and EFFECT level rises, and D.RANGE COMP. is automatically set to “MAX”.

This function does not work while MULTI/ 2CH A. DIRECT is on.

Note

No sound is output from the sub woofer when “2CH” is selected. To listen to 2 channel (stereo) sources using the front left and right speakers and a sub woofer, select “A.F.D.”.
