TO OPTIMIZE SOUND ND IMGE QULITY

Video Equipment

• Digital terminals are equipped with an S-Video (Separate Video) output connector, which provides superior image

quality compared to standard video (composite) connections. If your peripherals are equipped with this type of input,

we recommend that you use it.

Audio Equipment

• The coaxial output (RF) from digital terminals is monaural (which means it transmits sound in MONO only). If your

equipment supports stereo sound or you connect your terminal to a home theatre system, you are better off not using

this output as your main connector.

• All digital terminals are equipped with RCA analog audio output (left and right channels) and a coaxial digital audio

output connector (S/P DIF). Use the RCA outputs to connect your terminal directly to your TV, VCR, or standard sound

system.

• If you use your digital terminal with a home theatre receiver that has a digital audio decoder (Dolby Digital, DTS, etc.),

we recommend that you connect the receiver’s AC-3/PCM Digital In inputs to the terminal’s Digital Audio Out output.

This will provide you with superior sound quality compared to standard analog audio, and you will be able to enjoy

programs broadcast in Dolby Digital (AC-3) Surround, Pro-Logic Surround and 5.1.

• If your home theatre receiver is not equipped with S/P DIF input for digital audio, or if it is already in use and only an

optical input is available, you can purchase an S/P DIF optical converter.

• An RCA cable can be used for a digital audio connection if the two devices are less than 2 metres (6 feet) apart.

At greater distances, it is preferable to use a cable specially designed for the S/P DIF format.

HDMI (High Definition Multimedia Interface) Port

HDMI is a digital audio/video interface that supports Standard Definition Television (SDTV), Enhanced Definition Television

(EDTV) and High Definition Television (HDTV), as well as digital audio.

Some HDTV sets are not designed to decode audio content encoded with the Dolby

Digital standard. If you connect your

PVR HD directly to your HDTV and the latter does not support this standard, th HDMI interface will tell the PVR to output

the audio in PCM (two-channel stereo) format via its S/P DIF and optical digital audio outputs to make it compatible with

the HDTV set. In other words, sound will not be output to your receiver in Dolby

Digital if the connection is via one of

these two outputs. To work around this default configuration, select the "Dolby Digital" option under "Audio: Digital" in

the general settings.

Important: If your HDTV set cannot decode Dolby

Digital–encoded audio content and you have configured your PVR to

output audio in that format, you will not hear any sound from the TV’s speakers. In this case you must use your home

theatre receiver to process the audio signal. Alternatively, you could reconfigure the PVR to output audio in two-channel

PCM format when you want the sound to come out of the TV speakers. To do so, select the HDMI option under "Audio:

Digital" in the general settings. Other configurations may also be possible, depending on your TV’s other audio source

selection capabilities. For more information, refer to the user guides for your other components.

Note: If you are required to use an HDMI to DVI adapter (Explorer

series 8300 HD only) to connect your

terminal to your TV, you will have to make a separate audio connection, because the audio portion of the

signal will not be transmitted via the DVI port on your TV.
