The following components are usually included in your home theater system: 5 to 7 satellite speakers, subwoofer and a main component. This central element is the main hub of your home theater system. You will generally be able to control it by remote control. It is going to process the sound and split it into the sound component for every separate loudspeaker.
Locate this receiver in a place which minimizes the loudspeaker cable run to each speaker. Just be sure it is in a dry and safe location. Moreover, be sure that you can easily reach the receiver from your television set or DVD/Blue-ray player since you are going to need to connect these.
Connecting the receiver to power and to your television set or Blue-ray player is pretty straightforward. The majority of modern TVs have an optical output that attaches straight to your receiver using a fiberoptical cable. This cable is generally included with your system. You can also get it a many electronics stores. After you have established the audio link to your TV, you can now proceed and connect your speakers. This step demands a little more work.
If you have cordless rear loudspeakers you will not need as much loudspeaker cord and the setup will be a bit less complicated. First of all, calculate how much loudspeaker cable you are going to need. Be sure to add some extra cable to take into account those twists and corners. If you are planning to drive a lot of power to your loudspeakers then ensure you choose a cord which is thick enough to cope with the current flow. Many subwoofers are going to have a built-in amp and thus accept a low-level music signal. You can attach your subwoofer by using a shielded RCA cable.
While attaching the loudspeaker cable, make sure that you attach the cord with the right polarity. Every loudspeaker has a color-coded terminal, generally red and black. Select a speaker cable that shows one strand in a different color than the other. Then connect the cable to all speakers the same way. Next, when connecting the speaker cord to your receiver, make sure that you connect the cable to each speaker terminal at the receiver in the identical way. This will keep the sound going to every speaker in the right phase and optimize your sound experience.
Cordless loudspeakers normally need to do some audio buffering during the transmission in order to cope with wireless interference. This creates a brief delay while the audio is transmitted. This delay is also known as latency and should be taken into consideration during your set up. Ideally, all speakers have the same latency and therefore are in perfect sync. If you have cordless rears then the audio is going to by somewhat out of sync with your other loudspeakers. In order to keep all loudspeakers in sync you are going to need to tweak the receiver to delay the audio going to your wired loudspeakers.
Confirm with the manufacturer if your surround receiver can be set to delay the signal of specific channels. If you are using cordless rears, you want to set the front-speaker and side-speaker channels to delay the audio. If your receiver does not support adding an audio latency, you might want to pick a wireless speaker kit that has minimum audio latency in order to keep your speakers in sync. A number of available kits have audio latencies of less than one ms.
