also be used to drive two or more loud speakers for a theater-like audio experience. It may
also offer features such as Dolby Digital audio.
Dolby Digital Audio.
Some programs are broadcast with Dolby Digital audio: the
soundtrack is recorded on six separate channels, each of which can be heard on one of six
separate speakers. To hear Dolby Digital audio, you must use an Optical Digital Audio
cable (not supplied) to connect your DVR to an A/V receiver capable of supporting Dolby
Digital audio. Not all A/V receivers with optical audio inputs are capable of receiving
Dolby Digital audio. You must also set your DVR to record using Dolby Digital audio. For
more information, see page 80.
Dolby Surround Sound.
Dolby Surround Sound audio is a technique for encoding
surround sound audio on two channels. When decoded by a compatible A/V receiver, audio
on these two channels is separated into as many as five signals which play through your
home theater speakers. To hear Dolby Surround Sound audio, you must connect your DVR
to an A/V receiver that supports Dolby Pro Logic or Dolby Pro Logic II. You can use either
L/R (red and white) audio cables or an Optical Digital Audio cable.
Digital PBX Phone System.
Digital PBX phone systems allow many phones to share a
single telephone number and are usually used in hotels and office buildings. If you are
installing the DVR in your home, it is very unlikely that you are using a digital PBX phone
system. Do not connect your DVR to a digital PBX phone system. Doing so may
permanently damage your DVR’s modem and will void your warranty.
Surge Protector.
Like all electronics equipment, your DVR can be damaged by
fluctuations in your power supply. Purchasing a surge protector is highly recommended. If
you purchase a surge protector that allows you to plug in both your DVR’s power and your
telephone cord, you may prevent damage to the parts of your DVR that are connected to
your phone line as well!
