KNOW HOW ›MOBILE-SOUND‹ TECHNOLOGY
General introduction into mobile audio technology
The following tips, explanations and illustrations are to give you an understanding and facilitate the planning,
installation and use of mobile PA systems.
First we would like to mention that battery-/mains-operated mobile technology for the user means:
Laymen proof handling, small material cost (one-point or two-point acoustic irradiation),
mains-independence, cable-free operation and a very fast assembly and disassembly.
In most cases, these factors only allow a commercial acoustic irradiation, if at all, possible at great cost
with labour involving PA systems. We would like to give you some typical examples for the application
of mobile-sound technology in the following, which, by the way, you will find again in the second part of
this “guideline” supplemented by schematic drawings and explanations.
● Sports fields and halls
● Open air and indoor baths
● Churches, chapels and cemeteries
● Conference rooms and administration buildings
● Supermarkets and big stores
BASIC INFORMATION ON THE INSTALLING
OF MOBILE SYSTEMS:
Mobile systems and their applications
Speeches, panel discussions, conferences as well as musical
performances are normally amplified for the audience by
a PA system in order to be sufficiently understandable and
loud. Generally, PA systems are not used for the performance
of classical music and theatrical performance.
Additional acoustic irradiation has proven to be indispensable
for presentations of easy listening, lectures, discussions,
training courses and conferences.
The reasons for this are very distinctive audience expectations
as well as different degrees of required attention. RCS
has developed specific PA systems for this purpose. The
requirement of a PA system is to supply every listener equally
with sufficient direct sound. In doing so, a sound impression,
as natural as possible, is generated. A particular and
consistently recurring problem in practice is to avoid feedbacks
while amplifying sound waves. RCS´ PA systems are
especially developed for handling the problems that may be
expected.
Installation and placing the mobile systems
A professionally assembled sound system should be installed
accurately and inconspicuously. Please place your loudspeaker
systems so that they do not stand in corridors or
areas, which are accessible. In most cases, you will install
your speakers near the side walls and pointing to the audience.
This kind of assembly has several advantages: The
coupling of the sound produced within the loudspeakers to
the side walls improves your presentation, and the speakers
are less visible. Please lay all cables out of sight, and tape
them at accessible points to the floor in such a way, that
nobody trips or stumbles (please avoid laying mains and
speaker cables parallel to microphone cables). Please
remember, when adjusting the volume, that part of the
sound is absorbed by the audience in the room.

PLEASE NOTE:
Because of the audience noise in the background, an
additional higher sound pressure is required.
Start up mobile systems:
1. Check all connectors.
2. Adjust all volume controls to 0.
3. Switch your active system to ON. If other units are connected
to your system, switch these on first.
4. Talk into your microphone or start your player. Now turn
the AUX/Line or the (wireless) MIC volume control slowly to
the right, and adjust to the required volume. Regulate the
different inputs against each other, as you wish for your desired
presentation.
5. Adjust the equalizer controls to optimal playback quality.
When using a wireless microphone, note that feedback problems
may occur, if you are in front of the loudspeakers.
Please pay attention to the wireless microphone instruction
manual.
