SPEAKER SETUP FOR THIS UNIT

SPEAKERS TO BE USED

This unit is designed to provide the best sound-field quality with a 5 speaker configuration. The speakers to be used with this unit will be mainly front speakers, rear speakers, and a center speaker. (You can omit the center speaker. Refer to the 4-Speaker Configuration shown below.) The front speakers are used for the output of the main source sound and the effect sound. They will probably be the speakers of your present stereo speaker system. The rear speakers are used for the output of the effect sound. And the center speaker is used for the output of the center sound (most important effects as well as dialogue) encoded with the Dolby Surround. The rear and center speakers do not need to be equal in power to the front speakers. However, all the speakers should have high enough power handling to accept the maximum output of this unit.

SPEAKER CONFIGURATION

5-Speaker Configuration
This configuration is the most effective and is the one that is recommended. In this configuration, the center speaker is necessary as well as the rear speakers. If the digital sound field program is in DOLBY PRO LOGIC, ENHANCED or TV THEATER mode conversations will be output from the center speaker and the ambience will be excellent. q Set the center mode to the NORMAL or WIDE position. (For details, refer to page 13.) Front L Center Front R

4-Speaker Configuration

The center speaker is not used in this configuration. If the digital sound field program is in the DOLBY PRO LOGIC, ENHANCED or TV THEATER mode, the center sound is output from the left and the right front speakers. However, the sound effect of other programs can be the same as that of the 5-speaker configuration. q Be sure to set the center mode to the PHANTOM position. (For details, refer to page 13.)

ON SCREEN DISPLAYS
If you connect your video cassette recorder, video disc player, video monitor, etc. to this unit, you can take advantage of this units capability to display DSP program names and information about other various settings and adjustments on your video monitors screen. This information will be superimposed over the video image. If there is no video source connected or it is turned off, the information will be displayed over a monochromatic background. Notes q If you watch a video source that is connected to both S VIDEO and composite video input terminals of this unit, signals of screen display information are output from only the S VIDEO MONITOR OUT terminal. q When no video signal is input to either S VIDEO input or composite video input terminals of this unit, signals of screen display information are output from both S VIDEO MONITOR OUT and composite MONITOR OUT terminals with a monochromatic background. * For the General Model, if the PAL/NTSC switch on the rear panel is set to PAL, nothing will be output from either S VIDEO MONITOR OUT or composite MONITOR OUT terminal in this case.

FRONT IN terminals

These terminals are for line input to the built-in front-channel amplifier. Leave the jumper bars connected to FRONT OUT terminals when you use the built-in amplifier. However, if you drive front speakers with an external stereo power amplifier, remove the jumper bars.
<U.S.A. and General models>
The maximum power (total power consumption of components) that can be connected to the SWITCHED AC OUTLETS is 100 watts. The maximum power (total power consumption of components) that can be connected to the UNSWITCHED AC OUTLET is 200 watts.

REAR OUT terminals

These terminals are for rear-channel line output. If you use the built-in amplifier, there is no connection to these terminals. However, if you drive rear speakers with an external stereo power amplifier, connect the input terminals of the external amplifier to these terminals. If you use the built-in amplifier and the external power amplifier at the same time, the sound will be output only through the external one.

<Canada model>

The maximum power (total power consumption of components) that can be connected to the SWITCHED AC OUTLETS is 120 watts. The maximum power (total power consumption of components) that can be connected to the UNSWITCHED AC OUTLET is 180 watts.

<Australia model>

The maximum power (total power consumption of components) that can be connected to the SWITCHED AC OUTLET is 100 watts.

CENTER OUT terminal

This terminal is for center-channel line output. There is no connection to this terminal when you use the built-in amplifier. However, if you drive a center speaker with an external power amplifier, connect the input terminal of the external amplifier to this terminal. If you use the built-in amplifier and the external power amplifier at the same time, the sound will be output only through the external one.
REMOTE CONTROL (PHONO) connector
If you have a YAMAHA turntable with the terminal for remote control, connect it to this connector by using the cable provided with the turntable. This connection allows you to control the turntable from the provided remote control transmitter.

LOW PASS terminal

This terminal is for output to a mono amplifier driving a subwoofer. Frequencies above 200 Hz are filtered out so that only the bass range remains.
GND terminal (For turntable use)
Connecting the ground wire of the turntable to this terminal will minimize hum, but in some cases better results may be obtained with the ground wire disconnected.

ENGLISH

ANTENNA CONNECTIONS
Each antenna should be connected to the designated terminals correctly, referring to the following figure. Both AM and FM indoor antennas are included with this unit. In general, these antennas will probably provide sufficient signal strength. Nevertheless, a properly installed outdoor antenna will give clearer reception than an indoor one. If you experience poor reception quality, an outdoor antenna may result in improvement. Outdoor FM antenna Outdoor AM antenna

Description of Dolby Pro Logic Surround
DOLBY PRO LOGIC SURROUND: This unit employs the Dolby Pro Logic Surround system. This system is similar to professional Dolby Stereo decoders used in movie theaters. By employing a four-channel system, the Dolby Pro Logic Surround system divides the input signals into four levels: the left and right main channels, the center channel (to characterize dialog), and the rear surround-sound channels (to characterize sound effects, background noise and other ambient noise). Dolby Surround is encoded on the sound track of commercially available video cassettes and video discs as well. When you play a source encoded with Dolby Surround on your home video system, the Dolby Pro Logic Surround mode on this unit decodes the signal and feeds the surround-sound effects. The Dolby Pro Logic Surround mode may not be always effective on video sources not encoded with Dolby Surround.
Manufactured under license from Dolby Laboratories Licensing Corporation. Additionally licensed under one or more of the following patents: U.S. number 3,950,590; Canadian numbers 1,004,603 and 1,037,877. Dolby, Pro Logic, and the double-D symbol are trademarks of Dolby Laboratories Licensing Corporation.
To play a source with the digital sound field processor
Follow step 16 shown in OPERATIONS on page 15. Notes q If you prefer to cancel the selected program, press the ON/OFF switch. The sound will be the normal 2-channel stereo without surround sound effect. q In the ROCK CONCERT, JAZZ CLUB, CHURCH and CONCERT HALL modes, no sound is heard from the center speaker. q When a monaural sound source is played in the DOLBY PRO LOGIC or ENHANCED mode, no sound is heard from the front speakers and the rear speakers. Sound is heard only from the center speaker. However, if the center mode is in the PHANTOM, the front speakers output the sound of the center speaker. q If you connect an external amplifier to this unit, see if it has built-in surround sound or ambience circuitry. If it does, then be sure that the surround or ambience circuitry on that amplifier is off while you are using the digital sound field processors Dolby Pro Logic Surround decoding function. q When this unit is in the Dolby Pro Logic Surround mode, if the main-source sound is considerably altered by overadjustment of the BASS, TREBLE controls or BASS EXTENSION switch, the relationship between the center and rear channels may produce an unnatural effect.

Select the desired program that is suitable for the source.

The corresponding indicator will illuminate.
If desired, adjust the delay time and the output level of each speaker. (For details, refer to the corresponding descriptions on page 2223.)

Adjustment of DELAY TIME

You can adjust the time difference between the beginning of the source sound and the beginning of the effect sound with the DELAY TIME control. The DELAY TIME control is effective with all programs. By applying more or less delay, sound effects, background noise, and ambient noise coming at you from the rear speakers can be enhanced or subdued for extra effect. from 15 to 30 milliseconds (Preset value: 20 milliseconds) 2.

By continuously pressing + or on the DELAY TIME control, the value changes continuously. However, the value stops changing momentarily at the preset point.

DELAY TIME

DELAY ms
Adjustable. Note Adding too much delay will cause an unnatural effect with some sources. Experiment with the DELAY TIME control to create the effect that you find most suitable.
Adjustment of the FRONT EFFECT LEVEL
If desired, you can adjust the effect sound output level of the front speakers with this control. The output level is preset to be 80. However, you can adjust the level between 1 and 100.
If the digital sound field program is in the DOLBY PRO LOGIC mode, the FRONT EFFECT LEVEL control does not function. Once the output level is adjusted, the level value will be the same in all the digital sound field programs except for the DOLBY PRO LOGIC. If a digital sound field program is not used, the FRONT EFFECT LEVEL control does not function.

Appropriate input selector is not pressed. The sound suddenly goes off. Only one side speaker outputs the sound. Amplifier The protection circuit has activated because of short circuit etc. Incorrect setting of the BALANCE control. Incorrect cord connection. Sound hums. Incorrect cord connections.
