What is 7.1 channel, to those amplifiers speakers with, how to layout

A 7.1 system setup uses 4 surround speakers. For an optimal 7.1 setup, the SBL and SBR should be set to direct firing mode and placed together on the wall located at the back. This allows the THX Advanced Speaker Array, or ASA technology to deliver its best. If the SBLs and SBRs cannot be placed together, refer to the THX Setup menu of the preamplifier or rear amplifier for a compromise solution to maximize your system's potential.

The role of the 7.1-channel system is simply to establish a set of front and rear sound field around the listener's relatively balanced sound field, different from the 5.1-channel sound field is that it is based on the original increase in the rear of the sound field channel, at the same time, it is also different from the ordinary 6.1-channel sound field, because 7.1-channel has a two-way rear center, and the two-way rear center's biggest role is to prevent the listener from sitting in the emperor's seat and in the hearing of the sound field. Not sitting in the emperor's seat in the hearing of the sound field deviation. Because the human ear is divided into two left and right, then if your back only a center speaker, the sound field will be deviated, this deviation will cause sometimes you feel the sound is closer to the left, because your left ear first received the sound, and sometimes feel the sound in the right, and the sound field will not have a three-dimensional sense of sound, is almost very flat sound, sounds wrong. The reason is: when the front of your ear is not directly in front of the point of articulation, you need two speakers to correct the phase difference, which is why you need at least two speakers (stereo) to listen to music. So the soundstage and phase that can be created with two rear surround speakers is a much more advanced configuration in the home theater world.

DOLBY TRUEHD or DTS-HD BACK SURROUND PLACEMENT Dolby TrueHD and DTS-HD Rear Surround Arrangement

If you have a Dolby TrueHD and/or DTS-HD decoding-capable AV amplifier and you're playing a 7.1 split-track, you'll want to separate the two rear surrounds. Then you will want to separate the two rear surrounds at a 60 degree angle to the Emperor position. Additionally, you should make one adjustment to your amplifier settings. Simply go into the THX settings menu of your THX-certified front and rear amplifiers and set the ASA rear surrounds to "Split (greater than 48)"

FRONT SPEAKER PLACEMENT Main Speaker Arrangement

The front main speakers on the left and right are placed at ear height, creating a 45-degree angle to the Emperor position. that create a 45-degree angle with the emperor position. This conveys a wide sound stage and precise positioning of individual sounds.

CENTER CHANNEL SPEAKER PLACEMENT

The center channel speaker is placed either above or below the monitor. Based on this arrangement, the speakers are either high or low facing the listener. If you have an acoustically transparent [font class=t_tag href="tag.php?name=%C6%C1%C4%BB"]screen[/font], horizontally and vertically center this speaker behind the [font class=t_tag href="tag.php?name=%C6%C1%C4%BB"]screen[/font]. and vertically centered this speaker.

SIDE SURROUND SPEAKER PLACEMENT Side Surround Speaker Arrangement

The left and right side surround speakers reproduce the enveloping soundstage and intense effects that you would experience in a theater. These speakers are placed at an angle of 90 to 110 degrees from the listener and 2 feet or more above.

BACK SURROUND SPEAKER PLACEMENT Rear Surround Speaker Arrangement

The left and right rear surround speakers are DIRECT FIRING, placed together on the back wall to get the most out of THX's patented Advanced Speaker Array ASA technology. Using this speaker setup, THX ASA digitally reconfigures the surround channels to recreate the proper soundstage for movies, music, and games on the go.

If SBL and SBR can't be placed together, refer to the THX Setup menu of the preamplifier or postamplifier for a compromise solution to maximize your system's potential.

SUBWOOFER PLACEMENT Subwoofer placement

There are slight variations for subwoofer placement, depending on how many subwoofers your system has. If you have four, place them in a cross shape in the center of each wall. If you have two, place them in the middle of two opposing walls. If you have one, place it in the middle of the front wall.
