Cambridge SoundWorks MC630HD User Manual

-  -

   The switch located near the connection terminals optimizes the low 

frequency response of the speaker for wall or stand mounting. 

When the speaker is mounted on a speaker stand, away from 

the wall press the end of the switch marked with “|”. 

When the speaker is mounted on the wall or table, press the 

end of the switch marked with “o”. The upper bass range will 

be slightly attenuated to compensate for the increase in bass 

caused by wall reflection.

  The above recommendations should yield the most accurate 

response in each example, but they are optional. If you prefer the 

sound with settings opposite the above recommendations, feel free to 

use your settings instead.

  The MC630HD can be safely used with any receiver rated above 30 watts per channel. There is little advantage in using more power than 

100 watts per speaker, but receivers above this power rating can be used so long as the receiver is not operated at distorted levels.

Operating a receiver (of any power rating) beyond its maximum undistorted output level creates distortion – added high frequency sound not 

part of the musical program. Distortion dramatically increases the internal operating temperature of a speaker and will eventually cause the 

speaker’s failure due to burned or melted internal parts. While Cambridge SoundWorks includes the most heat-tolerant parts commensurate 

with good acoustic design, the speaker’s Limited Warranty against defects in materials or workmanship does not apply to parts that fail from 

long-term operation at very high temperatures.

  The speaker enclosures can be cleaned with a soft, damp cloth or mild cleaner. 

  Brush or vacuum the grille panels with a soft brush attachment to your vacuum cleaner.
