This component is also known as surround receiver and acts as the main control of your home theater system. Make sure that you put this receiver in a location that is fairly centrally located to minimize the amount of speaker wire which you have to run. You do not inevitably need to place the receiver right next to your TV. Most modern TVs include an optical output that connects straight to your receiver using a fiberoptical cord. You will not need as much speaker cable if your loudspeakers are wireless. You might want to add some extra length for safety. In most cases, you won’t be able to run the cable in a straight line to your speakers. You might need to consider carpets, furniture etc. The higher wattage you are driving into your speaker the higher the required gauge. If you are using wireless loudspeakers, there will be a short audio delay incurred throughout the audio transmission to the loudspeakers, also called latency. The amount of latency is dependent on the cordless system. If you have both cordless in addition to wired speakers, the cordless loudspeakers will be out of sync with the wired speakers. As a result you are going to have to delay the audio going to the wired speakers by tweaking your receiver. The rear-speaker audio which is going to the wireless rears should have no delay. Usually home theater systems that have been designed for loudspeakers which are cordless or include a wireless transmitter are going to include this capability and allow your speakers to be in phase.
