If you are using the Optical ¡ or the Coaxial ™ Digital Audio Output with an audio/video receiver or processor, you may select the Digital Output Format. If your receiver or processor is capable of decoding signals in the Dolby Digital or DTS format, select “Original” to make sure that these for- mats are passed through to the receiver for optimal audio performance. How- ever, if your receiver or processor is not capable of decoding these for- mats, set the digital output to “PCM” to enable the receiver or processor to play back 2-channel audio or use matrix decoding (e.g., Dolby Pro Logic I or II) if available (see Figure 21). Changes to this setting that are made during disc playback will not take effect until after play is stopped and restarted.

The PCM Limit setting enables you to select the sample rate for the digital audio output of the DVD280 that is compatible with the circuitry in your receiver or processor. Consult the owner’s manual for the receiver or processor to determine the maximum sampling rate your receiver or processor is capable of handling. Select the “48kHz” option if your receiver or processor is not capable of resolving digital signals greater than 48kHz, or if you are uncertain of your equipment’s capabilities. The DVD280 will down-sample any pro- gram material with higher sample rates so that it is compatible with your equipment. If your receiver or proces- sor is capable of handling digital sig- nals up to 96kHz, select that option. If your receiver or processor is capable of handling digital signals up to 192kHz, select the “No Limit” option. In this case, all signals will be passed through at their native rates without down-sampling. If you select the “96kHz” or “No Limit” options when your equipment is not capable of han- dling higher-resolution signals, then you will not hear any audio when a higher-resolution disc is played. Change this setting to “48kHz” so that the audio will be properly down- sampled (see Figure 22).

The Dynamic Range setting allows you to take advantage of the pro- gramming present on some Dolby Digital recordings to reduce the vol- ume of louder, peak passages so as to avoid disturbing others, while

maintaining intelligibility of quieter passages. The DVD280 accomplishes this by compressing the audio to a greater or lesser degree, depending on which setting you choose. The Minimum compression setting does not affect the original soundtrack at all. At the Medium compression set- ting, louder passages are a little bit quieter. At the Maximum compression setting, louder passages are much softer. Feel free to experiment with the settings at any time. Note that

if your receiver or processor also allows you to program the dynamic range setting and you have already done so, it is not necessary to pro- gram the dynamic range on the DVD280 and you should leave this setting at “Minimum” (see Figure 23).

The Video submenu is used to config- ure the DVD280 for compatibility with your video display.
