APPLICATIONS
ENHANCING THE SOUND OF TAPE DUPLICATIONS
Even under the most favorable of conditions, presence,
liveliness and transparency of the program material will
suffer during each copying process. These losses are par-
ticularly obvious when copying cassettes while simultane-
ously using a noise reduction system. With the MSE-
100A, losses during tape duplication can be avoided or
compensated for, provided that the original is of good
enough quality, with only low noise levels. It is even pos-
sible to produce “super” copies, which sound even better
than the original. For this application, the MSE-100A is
inserted between the line outputs of the source machine
and the inputs of the target machine. Machines with post-
head listening control (setting “Tape Monitor”) allow you to
check the quality of the copy while duplicating.
If the tape noise is fairly high, a different strategy is
required, since the MSE-100A can effectively process the
frequency ranges in which the most predominant noise
portions can be found. We recommend attenuation of
noisy high frequencies, either with an equalizer or prefer-
ably with a “single-ended” noise reduction system. The
MSE-100A will process those frequencies with all of their
natural clarity, but without the tape noise.
ENHANCING THE SOUND OF INSTRUMENTS
The bandwidth of most electronic musical instruments is
limited by its “sampling rate”. The MSE-100A can improve
the sound so that the synthesizers, samplers, and drum
machines have a more natural and transparent sound.
With the MSE-100A, even tiny details within the sound of
acoustic musical instruments such as guitars, etc., can be
emphasized without affecting the overall sound of the
instrument. Drum instruments, such as toms, bass drums,
etc., benefit from such “punch” and thus achieve a more
powerful, precise and defined sound.
Note: That low-level signal sources such as microphones,
guitars, etc., should pass through a preamplifier before the
processing stage, since the MSE-100A is a line-level
device (120 to +10 dBu).
ENHANCING THE SOUND OF P.A. SYSTEMS
If used in P.A. and other sound reinforcement systems, for
background or live music, the MSE-100A offers dramatic
advantages:
1. In audio systems for announcements and back-
ground music, the MSE-100A is placed in a
similar way to recording and tape duplication—
directly before the power amp. The intelligibility
and range of your system will be improved and
the sonic image will become clear and transpar-
ent, even at low volume levels. You will quickly
find that the MSE-100A can be a valuable tool
in solving otherwise difficult audio problems.
For instance, in clubs, you do not need to
constantly readjust the high frequencies as the
room becomes increasingly crowded. With the
MSE-100A, you will thus be able to protect your
speaker system and the hearing of your visitors.
Also, background music in bars and restaurants
can be heard more easily while keeping the
volume more manageable.
2. The sound of any P.A. system will be improved
by the MSE-100A. For example, vocals and
speech will be considerably more transparent
and intelligible, and the instruments can be
distinguished more easily.
The MSE-100A will increase the speaker system’s acous-
tic performance and its ability to penetrate a room, particu-
larly in places with difficult acoustics. The system will also
need less effective amplifier power, since the subjectively
heard volume level increases. Powerful and detailed
sound reproduction can thus be achieved in “weak” sys-
tems. Often the MSE-100A can help you prevent spend-
ing a small fortune on upgrading your entire system.
