Cautions
Please read the following operating precautions before use:
•
Use the AC adaptor designed specifically for the YST-M15/M20DSP 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-M15/M20DSPs 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-M15/M20DSPs do not contain any user serviceable parts. Refer all
servicing to your Yamaha dealer.
•
Do not expose the YST-M15/M20DSPs to temperature extremes, direct
sunlight, excessive dust, humidity, or vibration.
•
Place the YST-M15/M20DSPs on a level, stable surface. Do not drop the
YST-M15/M20DSPs, apply excessive force to their controls, or put heavy
items on top of them.
•
If the YST-M15/M20DSPs should require cleaning, use a soft cloth. If
necessary, use a damp cloth.
•
To protect the YST-M15/M20DSP speakers, avoid microphone feedback,
continuous and excessive output from electronic musical instruments
amplifiers signal distortion.
•
If the YST-M15/M20DSPs are located close to fluorescent or neon type lights,
a slight hum may be heard. In this case, relocate the YST-M15/M20DSPs
away from the light.
•
Although the YST-M15/M20DSP speakers are magnetically shielded, keep
floppy disks and tapes away from them.
•
The YST-M15/M20DSPs may cause picture distortion when placed close to a
television or computer monitor. In this case, move them away a little.

ADJ.VOL. knob:
Adjusts the level of the component connected to INPUT 1.
Use this adjustment if the sound from INPUT 1 is louder than INPUT 2.
Normally, leave it set to the MAX position.
When connecting two sources with different output levels, connect the source
with the higher output level to INPUT 1.

INPUT 1 and 2:
These are 3.5 mm jack connections for inputting signals to
the YST-M15/M20DSPs. 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.
3
TO LEFT SPEAKER: This should be connected to the TO RIGHT SPEAKER
connection on the left-channel cabinet using the supplied RCA plug cable.
