Yamaha’s Active Servo Technology offers exceptional high performance. Cautions Please read the following operating precautions before use: • • • • • • • • • • • • 6 Use the AC adaptor designed specifically for the YST-M8 only. Yamaha cannot be held responsible for damage caused by using other power supply adaptors. When disconnecting the AC adaptor from an AC receptacle, hold and pull the adaptor, not the power cord. If the YST-M8 are not going to be used for a while, disconnect the AC adaptor from the AC receptacle. Always disconnect the AC adaptor from the AC receptacle before making any connections. YST-M8 do not contain any user serviceable parts. Refer all servicing to your Yamaha dealer. Do not expose the YST-M8 to temperature extremes, direct sunlight, excessive dust, humidity, or vibration. Place the YST-M8 on a level, stable surface. Do not drop the YST-M8, apply excessive force to their controls, or put heavy items on top of them. If the YST-M8 should require cleaning, use a soft cloth. If necessary, use a damp cloth. To protect the YST-M8 speakers, avoid microphone feedback, continuous and excessive output from electronic musical instruments amplifiers signal distortion. If the YST-M8 are located close to fluorescent or neon type lights, a slight hum may be heard. In this case, relocate the YST-M8 away from the light. Although the YST-M8 speakers are magnetically shielded, keep floppy disks and tapes away from them. The YST-M8 may cause picture distortion when placed close to a television or computer monitor. In this case, move them away a little. This unit is not disconnected from the AC power source as long as it is connected to the wall outlet, even if this unit itself is turned off. This state is called the standby mode. In this state, this unit is designed to consume a very small quantity of power. Connections Refer to page 4 for system connections. Rear Panel (right cabinet) (Refer to page 5) 1 INPUT 1 and 2: These are 3.5 mm jack connections for inputting signals to the YST-M8. Using these two inputs will mix two input signals. For example, you may connect your CD-ROM player and personal computer to these input terminals. 2 TO LEFT SPEAKER: This should be connected to the TO RIGHT 3 4 SPEAKER connection on the left-channel cabinet using the supplied RCA plug cable. OUTPUT (ADJ. VOL.): This 3.5 mm stereo jack outputs the input signal after the VOLUME control. DC 12V: Connect the supplied AC adaptor to this connection. Rear Panel (left cabinet) 5 TO RIGHT SPEAKER: This should be connected to the TO LEFT SPEAKER connection on the right cabinet using the supplied RCA plug cable.  Specifications Front Panel (right cabinet) (Refer to page 5) Type Active Servo Technology Output power 5 W + 5 W (1 kHz, 4 Ω) Input sensitivity 200 mV (1 kHz, 4 Ω at 5 W) Input Impedance 25 kΩ Frequency response 80 Hz to 20 kHz Speaker unit 6.5 cm (2.5") full-range cone, magnetic shielding Output Impedance 600 Ω Output level 0.9 V (at 200 mV Rated Input) Power supply DC 12 V U.S.A. and Canada models AC 120 V, 60 Hz Europe and U.K. models AC 230 V, 50 Hz Australia model AC 240 V, 50 Hz Dimensions (W×H×D) 86 (3 3 /8") × 216 (8 1 /2") × 130 (5 1 /8") mm Weight 0.7 kg (1 lb 9 oz.)/Right channel unit 0.6 kg (1 lb 5 oz.)/Left channel unit Finish YST-M8 W: Computer white YST-M8 B: Black Accessories AC adaptor × 1 3.5 mm stereo mini plug cable × 1 RCA plug cable × 1 8 non skid pads × 1 * Specifications subject to change without notice. 6 (power) switch and indicator: Press the (power) switch to turn on the YST-M8; the indicator will light up. Press it again to turn off. Before turning on and off, turn down the VOLUME control. 7 VOLUME control: Use this control to set the volume level. Turn it clockwise to increase the volume, and counterclockwise to reduce it. 8 TONE control: This control allows frequency boost and cut up to ±7 dB at 10 kHz. This tends to emphasize vocals, providing a warmer intimate sound. Turn it clockwise to boost, and counterclockwise to cut. 9 (headphones) jack: Use this jack to connect stereo headphones for monitoring. No sound is output from the speakers or the OUTPUT (ADJ.VOL.) jack when headphones are connected. English Controls Non skid Pads The pads supplied with the YST-M8 should be stuck onto the bottom of each speaker cabinet as shown. As well as preventing the YST-M8 from slipping around, these pads also isolate the cabinet from the mounting surface. 7  Troubleshooting If your speakers fail to operate normally, check the following table.
