Dynaudio mc15 用户指南

Components of the highest quality are used in your MC 15. This 
assures years of trouble free operation. The following precautions 
should still be made, however.

NOTICE: Do not touch the drive units by hand. Especially the tweeter, 

which uses a very fine fabric dome with an ultra-thin coating.

X To clean the cabinet use a moistened cloth or a mild detergent.

Do not use aggressive cleaning solutions.

Hazardous voltage inside may lead to an electrical 

shock when opening the cabinet.
X Do not open cabinet. There are no user serviceable 

parts inside the speaker.

Power LED 
lights green 
but no sound.

No signal from 
preamplifier.

X Check the preamplifier and the 

signal source for proper cabling and 
setting.

Speaker is 
damaged.

X Switch speakers to check if the 

problem is caused by the speaker.

red.

overheated.

1. Check the temperature of the heat 

sink (5). If it feels hot turn off the 
speaker and wait for about 10 
minutes to allow the amplifier to 
cool off. Turn it on again.

2. If it works now it is ok, but you may 

need better air circulation around 
your speaker.

Using a wrong fuse type will damage the speaker and 

may cause fire.
X Replace fuse only with same type and rating.
