D8-10-1-3_EF S-W1EX_En_SRD6034A.book Page 3 Tuesday, October 11, 2005 6:51 PMS001_En Selecting fine audio equipment such as the unit you’ve just purchased is only the start of your musical enjoyment. Now it’s time to consider how you can maximize the fun and excitement your equipment offers. This manufacturer and the Electronic Industries Association’s Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level. One that lets the sound come through loud and clear without annoying blaring or distortion-and, most importantly, without affecting your sensitive hearing. Sound can be deceiving. Over time your hearing “comfort level” adapts to higher volumes of sound. So what sounds “normal” can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts. To establish a safe level:

• Start your volume control at a low setting.

• Slowly increase the sound until you can hear it comfortably and clearly, and without distortion. Once you have established a comfortable sound level:

• Set the dial and leave it there. Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all, we want you listening for a lifetime. We Want You Listening For A Lifetime Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since hearing damage from loud noise is often undetectable until it is too late, this manufacturer and the Electronic Industries Association’s Consumer Electronics Group recommend you avoid prolonged exposure to excessive noise. This list of sound levels is included for your protection. Decibel Level Example 30 Quiet library, soft whispers

Operating instructions x 1 FEATURES

250W (RMS) power with D class amplifier that serves audio and video software playback such as Dolby* Digital with a wide dynamic range.

Equipped with 30 cm driver

Turnover frequency can be continuous (50 – 150Hz, & Bypass).

Equipped with Bass Mode selector (Music/Cinema mode).

2 systems consisting of an input that connects to the amplifier's speaker terminals and an input that connects to the SUBWOOFER PRE-OUT terminal.

Fine-tuning the subwoofer with the help of world-class studio engineers. With the cooperation of AIR Studios, this subwoofer has been designated AIR Studios Monitor Reference: * Maunfactured under license from Dolby Laboratories. ”Dolby” and the double-D symbol are trademarks of Dolby Laboratories.

SPEAKERS The frequency characteristics of the S-W1EX combined with small-size speakers are shown below. As shown in these figures, the low frequency range is improved.• These special characteristics are obtained in an echoless chamber. The effect of an additional S-W1EX in an ordinary listening room is better than the chart indicates when positioned adequately.

• With playback of Dolby* Digital, establishment of a special channel for the subwoofer is recommended; and with playback of LFE (Low Frequency Effect: sound effect like the rumbling of the earth, whose purpose is to intensify the force of the video), the S-W1EX is especially effective. Dolby* Digital Dolby Digital is the name of the Dolby Surround multi-channel digital system that was developed from Dolby Surround, as a continuation of Dolby Pro Logic Surround.Dolby Digital is also referred to as a 5.1 channel system. This is because it has 5 channels in the 20Hz – 20kHz frequency range (front left and right, center, and rear left and right) and an independent channel for the subwoofer. The subwoofer channel is also referred to as LFE (Low Frequency Effect).

The LFE channel is used according to individual tastes to enhance the bass effect. INSTALLATION Before using this subwoofer, screw the 4 provided decoupling spikes. Make sure to use the spike bases provided (between the spikes and the floor) when placing the subwoofer. Speaker Installation

Recommended installation range for the subwoofer

Listening position The subwoofer plays back the bass in monaural, making use of the fact that the human ear is not very sensitive to the direction of low-pitched sound. Because of this, the subwoofer can be installed almost anywhere. If it is installed too far away, however, the sound from the other speakers may become unnatural.

An example of speaker positioning (ıı

Rear right speaker NOTE:

• To avoid interference with the picture on a nearby TV set, use magnetically shielded speaker systems. This is particularly important for the center speaker since it is usually located closest to the TV.

• Position the left and right channel speakers at equal distances from the TV set and approximately 1.8 meters from each other.

• Install the center speaker above or below the TV so that the sound of the center channel is localized at the TV screen.

• The rear (surround) speakers are most effective when installed in parallel locations directly to the side, or slightly behind, the listener, at a level about 1 meter above the listener's ears.

CAUTION: When installing the center speaker on top of the TV, be sure to secure it with tape or some other suitable means. Otherwise, the speaker may fall from the TV due to external shocks such as earthquakes, and it may lead to endangering those nearby or damaging the speaker.
