Patentierte Gehäuse
Die Gehäuse der BELL Lautsprechersysteme
werden in einem aufwändigen
Prozess nahtlos mit Wandstärken
von bis zu 70mm gefertigt.
BELL Dual Core Technologie
Die Entwicklung der patentierten
DUAL CORE Technologie ermöglicht
die Herstellung mehrschichtiger
Lautsprechergehäuse von höchster
mechanischer und akustischer Güte.
BELL Audio Systems
are the result of more than 40 years
of research and development.
The target performance
of each new model is focused on its
very specific applications.
Excessive prototype sessions
No longterm experience and no highly
sophisticated simulation software
will ever replace the need for working
prototypes and endless tests.

Pre-Production - Die Prototypen
Keine noch so grosse Erfahrung und
keine Computersimulation kann bei
seriöser Entwicklungsarbeit die zahlreichen
Prototypen auf dem langen
Weg zum Endprodukt ersetzen. So
werden in der Entwicklungsphase
eines neuen BELL Audio Systems
zahlreiche Arbeitsmuster erstellt. Erst
nach unzähligen Tests und weiteren
Optimierungsläufen wird das Produkt
zur Fertigung freigegeben.

Mechanische Qualität
Während herkömmliche Holzgehäuse
zumeist von Nägeln, Klammern und
Leim zusammen gehalten werden,
überzeugen die nahtlosen BELL Dual
Core Gehäuse durch ein um ca. 35%
niedrigeres Gewicht bei höchster
Stabilität und Wetterfestigkeit.

Quality in detail
BELL Speaker Systems are designed
around high quality components such
as US.magnetics, Fostex or B&C.
All Crossover networks are exclusively
manufactured 'in house' using only
selected audio grade foil capacitors,
PTC protection and air coils.
For perfect and safe installation
BELL speaker systems are prepared
for the use of overhead cradles,
U-brackets, aeroquip type flyingpoints-
and eyes as well as floor-,
wall- or satellite speaker stands.

SMP QX.serie
Die aktuelle BELL SMP.QX Serie
kombiniert die bewährte SMP
Endstufentechnologie mit den
Vorteilen des neu entwickelten
QX Amplifier Mangement Systems.
Digitales Amplifier Management
Das DSP Management beinhaltet
u.a.: Level, Delay, DSC, Polarität,
High-Pass Filter, Low-Pass Filter,
White- u. Pink Noise Generator,
8-Band EQ, Peak- u. RMS Limiter.
Sämtliche Parameter werden
direkt oder mittels BELL QX Audio
Remote Control Software editiert
und gespeichert.
RS485 Remote Control & Software
Über die RS485 Schnittstelle und
die mitgelieferte QX Software werden
bis zu 32 SMP-QX Endstufen
angewählt und gesteuert.
Switch mode power supply
Während das Gewicht einer
herkömmlichen 2000W Endstufe
kaum weniger als 30kg beträgt,
liegt das einer SMP2000QX mit
SMPS Netzteil bei lediglich 12,5kg.
Digital DSC Prozessor on board
Durch den pro Kanal zuschaltbaren
digitalen DSC Prozessor
erfährt die erlebte Dynamik der
SMP.QX Endstufen eine geradezu
dramatische Aufwertung.
Digital DSC steht für schnelle,
trockene Bässe und transparente,
kristallklare Höhen.
