Basic receiver setup entails plugging in audio and video sources and running wire from the unit’s back panel to your speaker’s input connections. Most DVD players, CD changers, satellite receivers, and cable boxes provide a digital audio output along with a set of regular analog output jacks. You’ll usually get better sound if you use this digital audio connection, and it’s an absolute requirement to experience the 5.1 channel digital soundtracks on DVD or HDTV programs. The rules for video setup on receivers are pretty much the same as those for audio.

The sound coming from your receiver needs to be divided up to match the capabilities of the speakers used in the system. To do this effectively, a receiver’s speaker setup menu lets you specify the size of individual audio speaker in the system as large or small, and asks whether or not you’re using a subwoofer. Th setting you select allow it to perform bass management, which determines the precise audio frequency at which bass signals are filtered out from the various speakers and sent on to the subwoofer.

The next step is to measure the span from the speakers to your seating position and specify those distances in the setup menu. This allows the receiver to perform time alignment basically adding slight delay to the audio channels to create a more uniform surround sound effect. And the final setup task is to balance the output levels of each speaker in the system. This ensures that setup task is to balance the output levels of each speaker in the system. This ensures that the sound coming from all speakers is equally loud, and important step for getting smooth dialog and realistic surround.some receivers perform the task automatically, with others, you need to use a sound pressure level meter along with the receiver’s built in setup test tones to manually make the adjustments.
