A home theater system can add another dimension to your viewing or gaming sessions. Crisp, clear sound which moves across the speakers in a direction which matches the pictures on the TV can enhance your pleasure and can be satisfying as you watch or play. Assuming you have all of the equipment ready to wire up, take a look at how to get the system working. Preparation Turn all of the equipment off so that you do not cause an injury while working with the system and speakers. Surround sound systems of all types run through a receiver. The receiver processes the sound and sends the signals to your speakers. Start by placing the receiver in a position which is close to the center of your set up, allowing all cables and wires to reach the receiver easily. Check The Speaker Connections Some of the systems use ports into which the speakers can be directly plugged, and others use a clip to hold the bare ends of the speaker wire in place. Check which kind your system uses, and if it uses clips, you may need wire-strippers to expose the wire for a good connection. Run each wire from the receiver to the speaker, ensuring that you hide the wire as much as possible. Not only will this look better, it will prevent people and pets from tripping over them. Remember to keep a little slack at each end; this allows you to make any small adjustments and prevents the wire connection from stressing. Once done, you can connect the speakers to the receiver. The Subwoofer The subwoofer uses a regular RCA cable to connect to the receiver; usually the port on the receiver is marked ‘sub pre-out’ or ‘sub out’. In case your subwoofer has multiple inputs, connect the cable at the far left to the receiver – this is sometimes labeled ‘LFE’ on the subwoofer. Remember to adjust the volume of the subwoofer. Place the subwoofer in the middle of your setup, as positioning it against a wall can cause bass and vibration issues. Connect HDMI Devices Modern receivers support HDMI input from your TV or console. HDMI connection transmits both visual and audio signals, so when connecting to the receiver, don’t worry about needing to connect other cables.  Plug the devices into the receiver’s HDMI ports; the order you plug them in will be the order they appear on the menu. Avoid stacking your devices – don’t put a DVD player under a console, as this can cause overheating. Composite Devices Many older devices still use the familiar three-pronged connecters – the red, yellow and white connectors. Match these up to the corresponding colored ports on...
