*NOTE: PMPO (Peak Music Power Output) is a non-
industry standard measurement that can be manipulated
to generate any value. A large PMPO number does not
mean more power or a better product.

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.
