Cambridge SoundWorks SoundWorks Digital Installation And Operating Instructions Manual - Playback Levels

Playback Levels
This speaker system is intended
for individual or small group
listening and will achieve
surprisingly high output levels.
However, playing the system
continuously at overly loud,
distorted levels on heavy-bass
program material may cause its
internal fuse to blow.
The fuse can be replaced only
by a qualified representative. To
avoid this inconvenience and a
possible non-warranty repair
charge, reduce the playback
volume when the system shows
obvious signs of stress—that is,
when it sounds “raspy,” “fuzzy,”
and/or “muddy.”
Controlling Noise and Distortion
(Analog Inputs Only)
Due to the high sensitivity of
SoundWorks Digital’s analog
inputs, some program sources
will send audible levels of
background hum and hiss
through to the speakers. In this
case, if the signal source has an
output level control (on-screen
control for a computer or variable
audio output for a TV or CD/tape
player), use one of the following
approaches:
1. Use a digital output
if one is present.
2. Reduce the setting of the
volume control until hum
or hiss is reduced to an
unnoticeable level. Use the
signal source to control the
output level.
3. Set the signal source’s volume
control to a high setting
(70% or higher) and use the
volume control to vary output.
Some PC sound cards have an
output control on the card. Trial
and error may be necessary to
achieve the right setting of this
control. Too low a setting could
cause background noise. Too
high a setting may cause
distortion.
Keep in mind that SoundWorks
Digital has sonic fidelity
sufficient to reveal noise and
distortion inherent in many
digital sound processors. You
may not have noticed these
imperfections before, even with
so-called “CD-equivalent” cards.
Background noise present in a
few, fixed-level signal sources
may be audible when the volume
control is set to a high level and
program material is silent or
playing at a low level. This
behavior is intrinsic to the fixed-
level signal source and is not the
fault of the speakers.
