Controlling Noise And Distortion; Specifications - Cambridge SoundWorks FPS1800 User Manual

Controlling Noise and Distortion

FPS1800 has high input sensitivity,
so it may amplify the hum and hiss
inherent in some audio program
sources.
This noise is not due to a fault in
the speaker system. You can minimize
this background noise by following
these guidelines:
❒
Decide which volume control you
would like to use as the master
level control: the FPS1800
volume control or the program
source's volume control.
If you choose to use the FPS1800
volume control, first set the
program source's volume control
high (at least 70% of the
maximum level). Where there is
more than one software level
control, set all volume controls
high. Then leave the controls. Use
the FPS1800 volume control to
adjust overall output.
If you choose to use the program
source's volume control, first set
the program source's volume
control high (at least 70% of the
maximum level). Then adjust the
FPS1800 volume control until the
distortion is inaudible. Set the
FPS1800 volume control aside.
Use instead the program source's
volume control to adjust overall
output.
❒
Adjust the output control of your
audio card until the noise
disappears. This may require trial
and error.
