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 fromhet 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).
