SPEAKER PLACEMENT
Although speakers should ideally be placed as shown below, try to adjust the speaker location according to the environment of your listening room so that you can experience the best sound field effect.
■Front speaker unit
Place the front speaker unit on top of the television and align the front surface of the speakers with the front surface of the television monitor. If the unit cannot be placed on top of the television, place it on a rack beneath the television as close to the television monitor as possible.
Rear speakers
Depending on room conditions, you can place rear speakers on shelves or hang them on the wall. Speakers should be placed about 1.8m above the floor.
Subwoofer
Place the subwoofer either at the right or left side of the front speaker unit and facing slightly toward the center of the room so that the sound from it and the sound reflected by the wall would not cancel each other out. As a transducer
is located on the left side panel of the subwoofer unit, place the subwoofer unit more than 10cm away from a wall or curtain. Try altering the position of the subwoofer versus the listening position as the relative position will affect the way the bass sounds.
CAUTION
- Although the speaker system in this unit is magnetically shielded, it may still affect the color on the television monitor when using this unit near the television. Adjust the relative positions of this unit and the television if this happen. Perform the following steps if you are using a television with a demagnetizing function.
1 Turn off the television.
2 Wait awhile and turn the television back on.
- Install the speaker system in a well-ventilated place.
- Since there is a low frequency sound output from the opening and transducer of the subwoofer, do not place an object near these areas of the subwoofer.
- When transporting the subwoofer, do not put your hand on the left side of the subwoofer. Doing so may damage the speaker or grille panel.
INSTALLATION
Installing the Front Speaker Unit
To prevent the front speaker unit from falling, secure it with the provided fastener when placing it on a television or other device. Also, use the height adjustment bracket on the rear of the front speaker unit when there is a step on the installation surface.
Using the fasteners
Precautions before installation
- Do not touch the adhesive surface after peeling off the strip as this will weaken its adhesive strength.
- Thoroughly wipe clean the surface where the fastener is to be applied. Note that adhesive strength is weakened if the surface is dusty, oily or wet and that this may cause the front speaker unit to fall.
Peel off the seal of the fastener with the rough surface and apply to the protrusions on the bottom of the front speaker unit.
2 Place the front speaker unit where it is to be installed (ex. on top of the television) to determine where to apply the fastener with the smooth surface.
Position it so that the fastener stuck to the front speaker unit matches that of the fastener stuck to the top of the television.
3 Peel off the seal of the fastener with the smooth surface and apply to the positions determined in step 2.
4 Align the fasteners on both sides and firmly press downward from the top of the front speaker unit.
Note
- Once the front speaker unit is secured in this way, the paint on the television surface used for installation may peel off when fastener is removed later. Be sure to apply fasteners after carefully checking the surface you are going to use for installation.
INSTALLATION
Using the height adjustment brackets
Precautions before installation
- Do not install the unit on a tilted surface, or in a place where there is not enough even space.

GLOSSARY
■Encode/Decode
When a signal or other information is processed, compressed and digitized, this is called encoding. Encoding can be used to record an extremely large amount of information on a single CD or DVD.
An encoded signal cannot be listened to directly. It must be returned to its original state (i.e. audible sound) and this is called decoding.
Sound field
Not all sound travels from the sound source directly into the human ear, but instead reflects off of walls, ceilings and other objects to arrive at the ear slightly delayed (early reflection). It may also reflect repeatedly in a complicated manner before reaching the ear (subsequent reverberation). A human is able to perceive the size and shape of a location based on the various sounds heard in this way. The specific acoustic space of a particular building is called a sound field.
■Dolby Surround
Dolby Surround uses a four analog channel recording system to reproduce realistic and dynamic sound effects: two left and right main channels (stereo), a center channel for dialog (monaural), and a rear channel for special sound effects (monaural). The rear channel reproduces sound within a narrow frequency range.
Dolby Surround is widely used with nearly all video tapes and laser discs, and in many TV and cable broadcasts as well. The Dolby Pro Logic decoder built into this unit employs a digital signal processing system that automatically stabilizes the volume on each channel to enhance moving sound effects and directionality.
■Dolby Digital
Dolby Digital is a digital surround sound system that gives you completely independent multi-channel audio. With three front channels (left, center and right), and two rear stereo channels, Dolby Digital provides five full-range audio channels. With an additional channel especially for bass effects, called LFE (low frequency effect), the system has a total of 5.1 channels (LFE is counted as 0.1 channel). Using two-channel stereo for the rear speakers, more accurate moving sound effects and surround sound environment are possible than with Dolby Surround. The wide dynamic range (from maximum to minimum volume) reproduced by the five full-range channels and the precise sound orientation generated using digital sound processing provide listeners with previously unheard of excitement and realism.
With this unit, any sound environment from monaural up to a 5.1-channel configuration can be freely selected for your enjoyment.
■DTS (Digital Theater Systems) Digital Surround
DTS digital surround was developed to replace the analog soundtracks of movies with a six-channel digital sound track, and is now rapidly gaining popularity in movie theaters around the world. Digital Theater Systems Inc. has developed a home theater system so that you can enjoy the depth of sound and natural spatial representation of DTS digital surround in your home. This system is a practically distortion-free, clear 6-channel sound (technically, a left, right and center channels, two rear channels, plus an LFE 0.1 channel as a subwoofer, for a total of 5.1 channels).
■LFE 0.1 channel
This channel is for the reproduction of low bass signals. The frequency range for this channel is 20Hz to 120Hz . This channel is counted as 0.1 because it only enforces a low frequency range compared to the full-range reproduced by the other 5 channels in a Dolby Digital or DTS 5.1 channel systems.
CINEMA DSP
Since the Dolby Surround and DTS systems were originally designed for use in movie theaters, their effect is best achieved in a theater with many speakers designed for acoustic effects. Since home conditions, such as room size, wall material, number of speakers, and so on, can differ so widely, it's inevitable that there are differences in the sound heard as well. Based on a wealth of actually measured data, YAMAHA CINEMA DSP uses YAMAHA original sound field technology to combine Dolby Pro Logic, Dolby Digital and DTS systems to provide the visual and audio experience of movie theater in the listening room of your own home.
■SILENT CINEMA
YAMAHA has developed a natural, realistic sound effect DSP algorithm for headphones.
Parameters only for headphones have been set so that accurate representations of the sounds can be enjoyed on headphones.
■VIRTUAL SURROUND
YAMAHA has developed a virtual CINEMA DSP algorithm that allows you to enjoy DSP sound field surround effects even without any rear speakers by using virtual rear speakers.
■PCM (Pulse Code Modulation)
PCM is a signal format under which an analog audio signal is digitized, recorded and transmitted without using any compression. Therefore, PCM may be called the liner PCM compared with the compressed audio signal such as Dolby Digital or DTS. This is used as a method of recording CDs and DVD audio. The PCM system uses a technique for sampling the size of the analog signal per very small unit of time. PCM which stands for "pulse code modulation" means that an analog signal is encoded as pulses and then modulated for recording.
TROUBLESHOOTING
Be sure to investigate the problem thoroughly before requesting repairs or after service. If the problem cannot be corrected or if it is not listed in the SYMPTOM column, disconnect the power cord and contact your authorized YAMAHA dealer or service center.
Notes
- Sometimes the unit may cease to recognize operations due to an error in operation or as a result of strong external noise (such as irregular voltage due to shock of impact, excessive static electricity, or lightning strike). If this happens, first disconnect the power cord, wait about 30 seconds, re-connect the power cord, and try the desired operation again.
- When requesting repairs or after service of the subwoofer and rear speakers, be sure to bring along the front speaker unit.
