Digital Input Signal Formats

The digital input signal formats are available only for the input sources that you have assigned a digital input jack; otherwise you will see “Analog” indicated on the screen (see page 39).

Normally, the AV receiver detects the signal format auto- matically. However, if you experience either of the fol- lowing issues when playing PCM or DTS material, you can manually set the signal format to PCM or DTS:

•If the beginnings of tracks from a PCM source are cut off, try setting the format to PCM.

•If noise is produced when fast forwarding or reversing a DTS CD, try setting the format to DTS.

	DIGITAL INPUT
1	Press and hold the AV receiver’s [DIGI-
	TAL INPUT] button for about 3 seconds.
2	While “Auto” is displayed (about 3 sec-

onds), press the [DIGITAL INPUT] button again to select: PCM, DTS, or Auto.

DTS or PCM: The DTS or PCM indicator, depending on which format you have set, flashes, and only signals in that format are output. Digital signals in other formats are ignored.

Auto (default): The format is detected automat- ically. If no digital input signal is present, the cor- responding analog input is used instead.
