Hook It Up
The very best way to connect your consumer electronic devices is with HDMI (High-Definition Multimedia Interface) connections. For 3D, you need one HDMI 1.4 connection or two separate HDMI 1.3 connections – 1 for video and 1 for audio.
Connecting Your Audio
1. If you do not have an A/V receiver, connect your gaming console or Blu-ray Disc player directly to your TV via HDMI.
2. If you have an A/V receiver, connect your gaming console or Blu-ray Disc player to your receiver via HDMI.
3. Then the receiver’s HDMI out goes to your TV. Check your receiver’s user manual to setup the routing properly.
Optical/Coaxial = Digital Out
Optical/coaxial cables will deliver up to 6.1 channels of digital audio, but you will need a separate cable to deliver video. DTS technologies maximize the digital out connection, delivering the maximum of audio bandwidth for the cable at 1509 kbps. This is the second best scenario for the best sound to match your high definition or exceed your standard definition picture.
Analog / RCA
Analog / RCA cables contain one channel per cable, so you need to match channels from one device to another. Audio still sounds good, but for flexibility and simplicity, it would be recommended to use a digital cable such as HDMI or Optical/Coaxial.
Once your speakers are positioned properly for surround sound, you want the correct directional sound levels coming from each speaker to complete the entertainment experience. Many receivers offer a self-calibration mode and there are various calibration tests that are on standalone discs or included with some game titles.
