TONEWINNER-AT-300-Channel-Pre-Pro-Summithifi-fig-14

Above diagram is for 7 .1.6 system, you can refer to it according to the quantities of the speakers you have

  • 1. Front left and right speaker
    • Front left and right speakers can output the overall sound effects, these speakers play the role of offering a single locating point in sound field of the home theater system. The recommend placing way is facing the listener & in the ear height, the distances between the speakers & listener should be the same as the distance between TV and listener. In order to get a better audition experience, please move the speakers slightly inward, so the listener can be in the vertex of a triangle formed by the speakers and listener.
  • 2. Center speaker
    • The center speaker reinforces the sound effect of left and right speakers, & it increase the movement of the sound thus make the sound filed completed. The center speaker plays the dialogue in the movie. Please put the center speaker right under or above the display device & make sure it is face to the listener in the ear height or in the same height to the front & left speakers.
  • 3. Subwoofer
    • Subwoofer handles the bass in the sound field. The sound quality and volume of the subwoofer are closely connected by the shape of your audition room & the position of the listener. The recommend position is a corner of the front part of the room or the one third width of the room.
  • 4. Surround left and right speakers
    • These speakers are for precise positioning of sounds, & increase the reality ofthe sound from all directions. Please put these speakers on the sides or slightly backward and the recommend install height is 60cm to 100cm above listener’s ears, & the ideal position is the distances from the listener to left surround and right surround speakers are the same.
  • 5. Rear surround left and right speakers
    • When the input signal is Dolby HD or DTS HD, these speakers are needed, they can help to enhance the surround sound effect & create a realistic immersive effect. The recommend install height is 40cm to 100cm above listener’s ears.
  • 6. 6,7,8. high speakers
    • Add sounds in vertical to the system & make a powerful immersive 3D stereo sound filed for you. Based on the object recording methods, it records the sound information and directions in details and do real time calculation for the sound data of each channel when decoding. Thus it can reproduce the real space orientation and moving track of the object sounds.
