To enjoy Surround mode or Stereo mode
DOLBY PRO LOGIC
This surround format consists of four channels (left and right front, center, and monaural surround channels) and emphasizes the center channel. This format is very effective for panning music, conversation, and three-dimensional sound movement output from three front channels. It also simulates the atmosphere and surround effects of the sound re�ected from the side and rear walls of the theater. Select this option when you play a VHS, VHS Hi-Fi, laser disc, or DVD video that has a mark.

Notes on DTS
1. If you play a CD or LD that supports DTS when the �ANALOG� setting is selected on the TX-DS484, the DTS encoded signal will not be decoded and noise will be output. This noise could damage the ampli�er and speakers. Therefore, be sure to select �DIGITAL� and use the digital input jacks (OPTICAL/ COAXIAL) to connect the DTS source. (Refer to �Switching between digital and analog inputs� on page 19.) 2. If you play a CD or LD that supports DTS when the �DIGITAL� setting is selected, you may hear a noise for a short while until the DTS decoder recognizes the DTS encoded signal and starts operating. This is not a malfunction. 3. If you press the PAUSE or SKIP button on the player while playing a DTS source, a short noise may be heard. This is not a malfunction. 4. The DTS indicator on the TX-DS484 lights up while it plays the DTS source. When playback concludes and the DTS signal transmission stops, the TX-DS484 remains in DTS mode and the DTS indicator remains lit. This prevents noise when you operate the PAUSE or SKIP button on the player. Therefore, if the source switches from the DTS signal to the PCM signal immediately, the PCM signal may not be played. In this case, stop the playback of the source on the player for about three seconds, then resume playback. 5. Some CD players and LD players may be unable to play DTS sources correctly even if you connect the player to the TX-DS484 digitally. This is because the digital signal has been processed (such as the output level, sampling frequency, frequency response, etc.), and the TX-DS484 cannot recognize the signal as DTS data. Therefore, you may hear noise when you play a DTS source while processing the signal. 6. The Rec Out jacks of the TX-DS484 output analog audio. Do not record CDs or LDs that support DTS using these jacks. Otherwise, you will record a DTS encoded signal as noise.
