Setting Bass Contour
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.
Note: Always place the switch in the “o” position if you are
using amplifier or receiver that does not have a high-pass filter
on the speaker outputs. Receivers and amplifiers that do not
have separate subwoofer outputs are in this category.
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.
Warning About Excessive Amplifier Distortion
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.
