English TROUBLESHOOTING When playing back a source encoded with DTS: Problem A loud hissing noise is heard when you play back a source encoded with DTS. A percussive noise is heard when you begin playing back a source encoded with DTS. No sound is heard when you play back a source encoded with DTS, even though the "AUTO" or "DTS" input mode is selected on this unit. No sound is heard when you play back an MD onto which you have recorded a source encoded with DTS. No sound is heard when you play back a DAT onto which you have recorded a source encoded with DTS. No sound is heard when you play back a source (CD etc.) even though the currently selected input mode is "AUTO". Cause The player which plays back the source is not connected to a digital audio signal input terminal of this unit. The "ANALOG" input mode is selected on this unit. If the "AUTO" input mode is selected, depending on some sources, there may be a case that a noise is heard while this unit is identifying the format of input signal. The DTS decoder built into this unit does not function because the player has a digital volume control and it is set at a position other than "maximum", "neutral" or "ineffective". A source encoded with DTS cannot be recorded onto an MD. What to Do The player must be connected to a digital audio signal input terminal of this unit besides analog audio signal terminal connections. Select a proper input mode on this unit to turn on the DTS decoder built into this unit. Set the input mode of the currently selected input source to "DTS". Set the player's digital volume control at the maximum, neutral or ineffective position. Depending on a DAT deck, a source encoded with DTS cannot be recorded onto a DAT. In the "AUTO" mode, DTS-decoding mode cannot be changed to the normal (PCM) digital signal input mode automatically. Press the INPUT MODE button on the front panel or the input selector button (for the currently selected source) on the remote controller so that "PCM" appears on the display. Notes • It is necessary to use a DTS decoder to play back a source encoded with DTS, so the player which plays back a source must be connected to a digital audio input terminal of this unit in the way described in this manual. If this connection is not made or only a D-to-A converter is used without using a DTS decoder, when you play back a source, only a loud hiss noise will be heard. • If you make a search (or skip etc.) operation while playing back a source encoded with DTS, the "dts" indicator goes out from the display. This is because this unit automatically changes the DTS-decoding mode to the standard (PCM) digital signal input mode to prevent a noise from being output. • A source encoded with DTS cannot be recorded onto analog audio and video tapes, and also, an analog tape recorded with a source encoded with DTS cannot be played back. The same result is obtained for MDs and DATs (depending on a DAT deck used for recording and/or playback). 73
