VOLUME

Thank you for purchasing Yamahas YST-MS30 Powered Multimedia Speakers. Advanced Yamaha Active Servo Technology offers exceptionally high performance, allowing these compact speakers to produce a rich bass sound.

Cautions

Please read the following operating precautions before use: When you disconnect the AC adapter from the AC receptacle, hold the plug, not the cord. If you plan not to use the YST-MS30s for a while, disconnect the AC adapter from the AC receptacle. Always disconnect the AC adapter from the AC receptacle before making any connections. The YST-MS30s do not contain any user serviceable parts. Refer all servicing to your Yamaha dealer. Never open the cabinet. If a foreign object drops into the set, contact your dealer, and do not use the YST-MS30s. Otherwise, you may cause a re. Do not expose the YST-MS30s to temperature extremes, direct sunlight, excessive dust, humidity, or vibration. Position the YST-MS30s on a level, stable surface. Do not drop the YST-MS30s, apply excessive force to their controls, or put heavy items on top of them. Do not place small metal objects on the speakers. Otherwise, the object may fall, possibly causing an injury. Since this unit has a built-in power amplier, heat will radiate from the rear panel. Therefore, place the unit apart from the walls, allowing a space of at least 20 cm (7-7/8") above, behind and on the both sides of the unit. Also, do not position with the rear panel facing down on the oor or other surface. (Subwoofer only) Do not obstruct the port with your hand or a foreign object. To protect the YST-MS30 speakers, avoid microphone feedback, continuous and excessive output from electronic musical instruments, and excessive signal distortion. If the YST-MS30s are located close to uorescent or neon lights, a slight hum may be heard. In this case, relocate the YST-MS30s away from the light. Although the YST-MS30 speakers are magnetically shielded, keep oppy disks and tapes away from them. The YST-MS30s may cause picture distortion when located close to a television or computer monitor. In this case, move them away a short distance. Avoid sources of hum (transformers, motors). To prevent re or electrical shock, do not expose to rain and water. Do not use force on switches, knobs, or cables. When you move the YST-MS30, rst turn off the power to the speakers, then disconnect the AC adapter from the AC receptacle and the cables from the connected devices.

Always turn the volume control counterclockwise to the minimum before starting to play the audio source: increase the volume gradually to an appropriate level after the playback has started.
Controls & Connectors
Refer to the illustrations on page 1.

1 TO RIGHT SPEAKER

Connect the 8-pin cable from the right satellite speaker to this connector.

2 INPUT 1/2

You can input two audio sources to the speaker system from these input jacks. For example, you can connect the output of a CD-ROM player and a personal computer here. The two audio sources are mixed together by the speaker system.

3 TO LEFT SPEAKER

Connect the RCA plug cable from the left satellite speaker to this connector.

4 BASS control

Allows you to adjust the volume level of the subwoofer. A typical (recommended) setting is the position between one oclock and two oclock. Rotating the control clockwise will increase the volume level, and rotating the control counterclockwise will decrease the level.

5 DC connector

Connect the included AC adapter to this connector. Press the (standby/on) button on the right satellite speaker to turn the power on or standby.

6 VOLUME control

Allows you to adjust the volume level of the entire speaker system. Rotating the control clockwise will increase the volume level, and rotating the control counterclockwise will decrease the level.
(standby/on) button/indicator Press this button to turn on the power to the speaker system. Its indicator lights up. Press the button again to turn the speaker system to standby mode. Before turning the power on or standby, make sure that the VOLUME control setting is lowered. A small electrical current ows through the speaker system even if the standby/on switch is turned off.
You can adjust the speaker angle. Loosen the screw on the bottom of the speaker stand as shown in the gure, adjust the angle of the stand, and tighten the screw to x the stand. To prevent the speakers from sliding around, attach the supplied pads to the four points on the bottom of each satellite speaker. Place the speaker on a stable, at surface.
