Important – Please Read Before Operating Your MicroWorks
Playback Levels
MicroWorks is intended for indi-
vidual or small group listening
and will achieve surprizingly 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 vol-
ume when the system shows
obvious signs of stress, i.e. it
sounds "raspy," "fuzzy,"
and/or "muddy."
Controlling Background Noise and Distortion
Due to MicroWorks' high input
sensitivity (only .18 V RMS for
rated output), some signal sources
will send audible levels of back-
ground hum and hiss through
to MicroWorks.
If hiss or hum is heard from
MicroWorks and if the signal
source has its own volume control
capability (on-screen control for a
computer or variable audio output
for a TV or CD/tape player), use
one of the following
two approaches:
1. Reduce the setting of the
Volume Control until hum or
hiss is reduced to an unnotice-
able level. Use the signal
source to control the
output level.
2. 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 boards 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, MicroWorks 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 behav-
ior is intrinsic to the fixed-level
signal source and is not the fault
of MicroWorks.
