Using Listening Mode
Before Using Listening Mode Listening Modes
The DTR-5�s surround sound enables you to enjoy the presence of a movie theater or concert hall in your room. Before using a listening mode, make sure the Speaker Setup parameters have been set (refer to page 14). Once the parameters have been set, it is not necessary to set them again. The con�guration of the speakers are very important for the surround sound. Refer to �connecting speakers� on page 10.

The following modes are available: DOLBY 3STEREO The surround channel sound is output from the left and right front speakers. STEREO This is a normal stereo mode. Surround mode is cancelled.

� A system with L/R front speakers

DOLBY DIGITAL Surround, DTS (Digital Theater System) Surround
This 5.1-channel digital surround format enables you to individually record and play �ve full-range (20Hz�20kHz) channels (left and right front, center, two surround channels) plus an LFE channel (Low Frequency Effect) for the low-range effect sound. It will create a realistic sound that could be heard in the theaters and concert halls. DOLBY DIGITAL: Select this option when you play a DVD video that has a mark. DTS: Select this option when you play a DVD player, laser disc, or CD 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 DTR-5, 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 �Audio (digital or analog) selection� on page 18.) 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 DTR-5 lights up while it plays the DTS source. When playback concludes and the DTS signal transmission stops, the DTR-5 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 DTR-5 digitally. This is because the digital signal has been processed (such as the output level, sampling frequency, frequency response, etc.), and the DTR-5 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 DTR-5 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.

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.
