Input modes and indications

This unit is equipped with a variety of input jacks. You can select the type of input signals you wish to use.

Each time you turn on the unit power, the input mode is set to the “INPUT 2 INPUT MODE” setting defined in the set menu.

Press INPUT MODE repeatedly until the desired input mode is shown on the front panel display.

		Input mode
AUTO:	In this mode, the input signal is selected
	automatically as follows:
	1) Digital signal
	2) Analog signal
DTS:	In this mode, only digital input signals
	encoded with DTS are selected, even if the
	unit is receiving another signal
	simultaneously.
ANALOG:	In this mode, only analog input signals are
	selected, even the unit is receiving digital
	signals at the same time.

Notes

•When AUTO is selected, this unit automatically determines the type of signal. If it detects a Dolby Digital or DTS signal, the decoder automatically switches to the appropriate setting.

•When playing a disc encoded with Dolby Digital or DTS on some LD or DVD players, there is a delay in sound output for a moment when playback resumes after a search, because the unit must select the digital signal again.

•When playing a LD source that has not been digitally recorded, the unit may not output any sound for some LD players. In this case, set the input mode to ANALOG.

■Notes on digital signals

The digital input jacks of this unit can handle 96 kHz sampling digital signals. Note the following when a digital signal with a sampling frequency greater than 48 kHz is input to this unit:

•You cannot use any DSP programs.

•The unit will output sound as 2-channel stereo from the main left and right speakers only. Therefore, you cannot adjust the level of the effect speakers while listening to such a source.

■Notes on playing DTS-CD/LDs

•If the digital output data of the player has been processed in any way, the unit may not be able to perform DTS decoding even if there is a digital connection between this unit and the player.

•If you play a source encoded with a DTS signal and set the input mode to ANALOG, the unit may reproduce the noise of an unprocessed DTS signal. In this case, connect the source to a digital input jack on this unit and set the input mode to AUTO or DTS.

•If you switch the input mode to ANALOG while playing a source encoded with a DTS signal, the unit does not output any sound.

•If you play a source encoded with a DTS signal with the input mode set to AUTO;

–The unit automatically switches to the DTS- decoding mode (The “t” indicator lights up) after detecting the DTS signal. When playback of the DTS source is completed, the “t” indicator may flash. While this indicator is flashing, the unit can only reproduce DTS source. If you want to play a normal PCM source immediately, change the input mode back to AUTO.

–When the input mode is set to AUTO and a search or skip operation is performed during playback of a DTS source, the “t” indicator may flash. If this state continues for longer than 30 seconds, the unit will automatically switch from “DTS-decoding” mode to PCM digital signal input mode. The “t” indicator will turn off.
