Page 5 You are the proud owner of a Yamaha stereo amplifier —an extremely sophisticated audio component. Follow the instructions in this manual carefully when setting up your system, and this unit will sonically transform your room into a wide range of listening environments —movie theater, concert hall, and so on.
In addition, you get incredible realism from Dolby-encoded video sources using the built-in Dolby Pro Logic Surround Decoder. Please read this operation manual carefully and store it in a safe place for later reference. Dolby Pro Logic Surround provides a true center channel, so that there are four independent channels, unlike passive Dolby Surround which has in effect only three channels: left, right, and rear. This center channel allows listeners seated in even less-than-ideal positions to hear the dialog originating from action on the screen while getting a stereo effect as well.
It recreates the surround effect of a movie theater, effectively duplicating its multiple surround loudspeaker system, completely surrounding the listener with the sounds of the action taking place on the screen. 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. The front speakers are used for 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 effect sound. And the center speaker is used for the center sound dialog etc. 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.
In this configuration, the center speaker is necessary as well as the rear speakers. For details, refer to page The center speaker is not used in this configuration. However, the sound effect of other programs can be the same as that of the 5-speaker configuration. When you place these speakers, refer to the following. Front: In normal position. The position of your present stereo speaker system. Rear: Behind your listening position, facing slightly inward.
Nearly six feet approx. Center: Precisely between the front speakers. To avoid interference with TV sets, use a magnetically shielded speaker. LD player, TV tuner, etc. Note If video signals are sent to both S VIDEO input and composite input terminals, the signals will be sent to their respective output terminals independently.
One or two center speakers can be connected to this unit. If you cannot place the center speaker on or under the TV, it is recommended to use two center speakers and place them on both sides of the TV to orient the center sound at the center position. For connecting two center speakers, follow the method shown below. If the connections are faulty, no sound will be heard from the speakers.
If these wires are reversed, the sound will be unnatural and will lack bass. Note Use speakers with the specified impedance shown on the rear of this unit. Simply insert the Banana Plug connector into the corresponding terminal. These outlets will supply power to any component whenever this unit is turned on.
These terminals are for front channel line output. There is no connection to these terminals when you use the built-in amplifier. However, if you drive front speakers with an external stereo power amplifier, connect the input terminals of the external amplifier MAIN IN or AUX terminals of a power amplifier or an integrated amplifier to these terminals. REAR OUTPUT terminals Connecting the ground wire of the turntable to this terminal will normally minimize hum, but in some cases better results may be obtained with the ground wire disconnected.
These terminals are for rear channel line output. However, if you drive rear speakers with an external stereo power amplifier, connect the input terminals of the external amplifier MAIN IN or AUX terminals of a power amplifier or an integrated amplifier to these terminals.
Only frequencies below Hz from the front and center channels are output. 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. With some subwoofers, including the Yamaha Active Servo Processing Subwoofer System, the amplifier and subwoofer are in the same unit.
With this adjustment, the sound output level heard at the listening position will be the same from each speaker. This is important for the best performance of the digital sound field processor.
The adjustment of each speaker output level should be done at your listening position with the remote control transmitter. Otherwise, the result may not be satisfactory. Select the front speakers to be used. Note In step 6, when you select the center channel output mode, note the following. In this mode, the bass tone will be output from the front speakers. WIDE: Select this mode when you use the center speaker approximately same sized as the front speakers.
You will hear a test tone like pink noise from the left front speaker, then the center speaker, then the right front speaker, and then the rear speakers, for about two seconds each. The display changes as shown below. The center sound will be output from the left and right front speakers. Cancel the test tone. Lights up. This is because in this mode, the center sound is automatically output from the left and right front speakers. Refer to page Notes on using the input selector buttons Note that pressing on each input selector button selects the source which is connected to the corresponding input terminals on the rear panel.
Select the source to be recorded. Set the tape deck or VCR to the recording mode. Adjusting the BALANCE control Adjust the balance of the output volume to the left and right speakers to compensate for sound imbalance caused by speaker location or listening room conditions. Note These controls are effective only for the sound from the front speakers.
You can listen to the sound to be output from the front speakers through headphones. You can create an excellent audio sound field by selecting the suitable program and adding desired adjustments. This presents you the best surround condition without manual adjustment. Selects the center channel output mode. Adjusts sound output level at each speaker. 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. Page 7: Connections Before attempting to make any connections to or from this unit, be sure to first switch OFF the power to this unit and to any other components to which connections are being made. Center speaker Note on front speaker connection: One or two speaker systems can be connected to this unit.
If the connections are faulty, no sound will be heard from the speakers. With some subwoofers, including the Yamaha Active Servo Processing Subwoofer System, the amplifier and subwoofer are in the same unit. With this adjustment, the sound output level heard at the listening position will be the same from each speaker.
This is important for the best performance of the digital sound field processor. Page 13 Select the center channel output mode according to your speaker configuration. Note In step 6, when you select the center channel output mode, note the following. Set the tape deck or VCR to the recording mode.
This digital sound field processor has 8 programs; Keep in mind that most of these are precise digital recreations of actual acoustic environments. The data for them was recorded at the locations described using sophisticated sound field measurement equipment. Select the desired program that is suitable for the source. Yamaha sound in Direct mode with disabled voices were strong, with deep bass, but somewhat cumbersome and colorless.
But when included voices DSP-A sounds just fine: powerful bass at high-sounding and clear the "middle"! At the same time, the inclusion of different modes of surround sound Surround very significantly changed the character of the amplifier, but the very sound becomes somewhat artificial and unnatural. This was particularly evident in the sound of percussion instruments, such as cymbals, the sound of which, as it was duplicated and was accompanied by a strong digital echo.
Three-dimensional sound image created by AV-amplifier mode Dolby Pro Logic, an enviable bulkiness and lots of sonic detail. Yamaha confident arranged the sound sources both in front and in depth, it created soundscapes were almost tangible. The sound quality, especially in the low frequency range was great.
