Connecting Audio Components
I Connecting to digital jacks
This unit has digital jacks for direct transmission of digital signals through either coaxial or fiber optic cables. You can use the digital jacks to input PCM, Dolby Digital and DTS bitstreams. When you connect components to both the COAXIAL and OPTICAL jacks, priority is given to the input signals from the COAXIAL jack.
I Connecting an MD recorder, CD recorder or tape deck
Connect the analog input/output jack of your recording component to the AUDIO jacks.
When you connect a recording component to this unit, keep its power on while using this unit. If the power is off, this unit may distort the sound from other components.
You can designate the input for each digital jack according to your component by using 3 I/O ASSIGN in the SET MENU.
Connecting an External Decoder
This unit is equipped with 6 additional input jacks (left and right MAIN, CENTER, left and right SURROUND and SUBWOOFER) for discrete multi-channel input from an external decoder, sound processor or pre-amplifier. Connect the output jacks on your external decoder to the 6CH INPUT jacks. Be sure to match the left and right outputs to the left and right input jacks for the main and surround channels.
When making connections between the digital signal jacks, you should connect the components to the same-named analog audio signal jacks of this unit, because a digital signal cannot be recorded by a recording component connected to this unit. All digital signal input jacks are applicable to sampling frequencies of 32 kHz, 44.1 kHz and 48 kHz.
About the dust protection cap Pull out the cap from the optical jack before you connect the fiber optic cable. Do not discard the cap. When you are not using the optical jack, be sure to put the cap back in place. This cap protects the jack from dust.
When you select 6CH INPUT as the input source, this unit automatically turns off the digital sound field processor, and you cannot listen to DSP programs. When you select 6CH INPUT as the input source, changing items of 1 SPEAKER SET in the SET MENU is not affected (except MAIN LVL).
The OPTICAL jacks on this unit conform to the EIA standard. If you use a fiber optic cable that does not conform to this standard, this unit may not function properly.
I Connecting a CD player y

The COAXIAL jack is available for a CD player which has coaxial digital output jack. When you connect a CD player to both the analog and digital jacks, priority is given to the input signals from the digital jack.

PROGRAM

0104V420RDS21-25_EN 22 2/12/1, 1:35 PM
Input Modes and Indications
This unit comes with various input jacks. If your component is connected to more than one type of input jack, you can set the priority of the input signal. Press INPUT MODE (or the input selector button that you have pressed to select the input source on the remote control) repeatedly until the desired input mode is shown on the display.
I Notes on playing a source encoded with a DTS signal
If the digital output data of the player has been processed in any way, you may not be able to perform DTS decoding even if you make 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, this unit reproduces the noise of an unprocessed DTS signal. When you want to play a DTS source, be sure to connect the source to a digital input jack 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, this unit reproduces no sound. The following phenomena may occur if the input mode is set to AUTO when playing back a source encoded with DTS: If you continue to play a source encoded with a DTS signal, this unit automatically switches to the DTSdecoding mode to prevent noise from being generated during subsequent operation. (The t indicator lights up on the display.) The t indicator may flash immediately after playback of a source encoded with a DTS signal has finished. Only a source encoded with a DTS signal can be played back while this indicator is flashing. (The indicator will flash for less than a minute.) If you want to play a normal PCM source soon, set the input mode back to AUTO. The t indicator may flash when a search or skip operation is performed. If this status continues for a certain length of time, the unit will automatically switch from the DTS-decoding mode to PCM digital signal input mode and the t indicator will go out.

Input mode

Changing the RDS Mode

The four modes are available in this unit for displaying RDS data. When an RDS station is being received, PS, PTY, RT and/or CT that correspond to the RDS data services offered by the station light up on the display. Press RDS MODE/ FREQ repeatedly to change the display mode among the RDS data offered by the transmitting station in the order shown below. Illumination of the red indicator next to the RDS mode indicator shows that the corresponding RDS mode is now selected.

Description of RDS Data

This unit can receive PI, PS, PTY, RT, CT, and EON data when receiving RDS broadcasting stations.
When an RDS station is being received, do not press RDS MODE/FREQ until one or more RDS mode indicators light up on the display. If you press the button before the indicators light up on the display, the mode cannot be changed. This is because the unit has not yet received all of the RDS data on the station. RDS data not offered by the station cannot be selected. The RDS data service cannot be utilized by this unit if the received signal is not strong enough. In particular, the RT mode requires a large amount of data to be received, so it is possible that the RT mode may not be displayed even if other RDS modes (PS, PTY, etc.) are displayed. RDS data cannot sometimes be received under poor reception conditions. If so, press TUNING MODE so that the AUTO indicator goes off from the display. Although the reception mode is changed to monaural by this operation, when you change the display to RDS mode, RDS data may be displayed. If the signal strength is weakened by external interference during the reception of an RDS station, the RDS data service may be cut off suddenly and.WAIT will appear on the display.
I PS (Program Service name) mode:
The name of the RDS station being received is displayed.
I PTY (Program Type) mode:
The program type on the RDS station being received is displayed. There are 15 program types to classify RDS stations. You can make this unit search for a station which is broadcasting a program of the desired type. Refer to PTY SEEK Function for details.

I RT (Radio Text) mode:

Information about the program (such as the title of the song, name of the singer, etc.) on the RDS station being received is displayed by a maximum of 64 alphanumeric characters, including the umlaut symbol. If other characters are used for RT data, they are displayed with under-bars.

This program recreates the acoustic environment of a lively disco in the heart of a big city. The sound is dense and highly concentrated. It is also characterized by a highenergy, immediate sound. Using this program increases the listening position range. This is a sound field suitable for background music at parties.

5CH STEREO

Reverberations (sound effects) for realizing the sound field and unprocessed stereo from the left and right main speakers is output. The sound is not output from the center speaker. (The sound is output when one of these programs is selected while playing a source encoded with a Dolby Digital or DTS signal. If 5CH STEREO is selected, the sound is output from all speakers regardless of the input source.)

CINEMA DSP Programs

I For audio-video sources: Nos. 4 to 6
No. Program (group) ENTERTAINMENT TV SPORTS Sub-program GAME Features This program adds a deep and spatial feeling to video game sounds. Although the presence sound field is relatively narrow, the surround sound field employs the sound environment of a large concert hall. With this program, you can enjoy watching various TV programs such as news, variety shows, music programs or sports programs. In a stereo broadcast of a sports game, the commentator is oriented at the center position, and the shouts and the atmosphere in the stadium spread on the surround side, while their spread to the rear is properly restrained. This program is provided for reproducing monaural video sources (such as old movies). The program produces the optimum reverberation to create sound depth by using only the presence sound field.

MONO MOVIE

0108V420RDS43-45_EN 43 2/12/1, 1:36 PM
I For movie programs: Nos. 7 to 9
No. 7 Program (group) Sub-program 70 mm SPECTACLE Input source Analog, PCM, Dolby Digital in 2-channel Dolby Digital (5.1-channel) Features This program creates the extremely wide sound field of a 70-mm movie theater. It precisely reproduces the source sound in detail, making both the video and the sound field incredibly real. This is ideal for any kind of video source encoded with Dolby Surround, Dolby Digital or DTS (especially large-scale movie productions). This program clearly reproduces dialog and sound effects in the latest sound form of science fiction films, thus creating a broad and expansive cinematic space amid the silence. You can enjoy science fiction films in a virtual-space sound field that includes Dolby Surround, Dolby Digital and DTS-encoded software employing the most advanced techniques. This program is ideal for precisely reproducing the sound design of the newest 70-mm and multichannel soundtrack films. The sound field is made to be similar to that of the newest movie theaters, so the reverberations of the sound field itself are restrained as much as possible. This program is for reproducing sounds from 70-mm and multichannel soundtrack films, and is characterized by a soft and extensive sound field. The presence sound field is relatively narrow. It spatially spreads all around and toward the screen, restraining the echo effect of conversations without losing clarity. For the surround sound field, the harmony of music or chorus sounds beautifully in a wide space at the rear of the sound field. The built-in decoder precisely reproduces sounds and sound effects from sources. The highly efficient decoding process improves crosstalk and channel separation, and makes sound positioning smoother and more precise. In this program, the digital sound field processor is not turned on. MOVIE THEATER 1 SPECTACLE
