Dolby Digital Sound with 5.1 Channels

The Zenith HD Satellite Receiver will be the focal center of your home entertainment system com- prising a variety of components, such as TV, DVD, VCR, etc. and external audio systems. Since digital programs being broadcast contain digital-quality audio, you can create a home theater by sending audio signals from the HD satellite receiver to your audio system externally. HD digital signals use the Dolby Digital audio encoding system - the same digital sound used in most movie theaters, on DVDs, and in many home theater systems.

When you tune to a channel, the Zenith HD Satellite Receiver can send signals either to a Dolby Digital decoder/receiver or to a PCM (normal digital) decoder. (* Refer to Section 3.7 Connection for Audio for making the required external connections to your system.)

Using the analog mode of the Zenith HD Satellite Receiver allows use of your Hi-Fi audio system instead of the TV speakers. This usually results in substantially improved sound.

GLOSSARY

Dolby Digital, formally known as AC-3 for Audio Coding 3rd Generation or “5.1” channel audio, is a coding technique that provides five independent, full frequency response audio channels (three in left, center, and right, two in rear left and right, and one low frequency effect for a sound you can feel).

Pulse Code Modulation (PCM) decoders support L/R stereo only. If select- ed, audio outputs are decoded and transmitted in PCM mode.
