A great idea is to test and measure even distances from the seating position to each speaker. The subwoofer is a non-directional speaker, so it can be placed anywhere in your room. You may need to consider a longer than supplied subwoofer cable, the final resting place could be at the other end of your room. Check the manufacturer’s recommendations before replacing any provided cables with good quality OFC home theatre speaker cable, doing this can increase sound quality. The AV Receiver channel level adjustment is useful for fine tuning sound to your satisfaction. Each manufacturer has perfectly matched power output providing optimal speaker performance. Choosing the correct AV Receiver matching your speakers is not required with “in a box” home theatre systems. It’s also a great idea to look for USB input, allowing connection of your favourite MP3 player like an iPod. Also Ensure your home theatre system choice has enough inputs to handle extra components. Glossary AV Receiver The AV receiver also acts like a hub or central point handling additional components audio and video signals routing them into one cable connected to your TV. Powers your speakers and subwoofer, the AV receiver power rating indicates what size speakers you can buy. Channels Refer to the user manual provided by the manufacturer for the correct speakers to use with each channel. Channels are used to connect your speakers; each channel has a positive and negative terminal. Dolby Digital, Dolby Digital EX Using the Dolby unique encoding and decoding process bring your movies to life. Dolby Digital represents a digital sound format used by Hollywood studios, recreating realistic effects in movies. As sound formats change, more channels are added to the traditional 5.1. For example, Dolby Digital EX has 7.1 unique channels of sound therefore more speakers are required. DTS When compared to Dolby Digital, DTS has a higher fidelity rate due to its 20-bit audio compression. It is a sound format created by Digital Theatre Systems in 1993; US based and dedicated to delivering the ultimate entertainment experience. HDMI An uncompressed digital video (1080p Full HD) is carried in a High Definition Multimedia Interface and audio in one neat and tidy cable to your LCD or Plasma TV. Seating position use the speaker and TV placement guide provided by the manufacturer for the best sound and picture quality and check your preferred seating position. Subwoofer The positioning of the subwoofer is extremely important. A large speaker used to create BASS, usually has its own power amplifier classing it as an “active” speaker.
