1. THE V-DOSC SYSTEM STANDARD
V-DOSC is a complete, self-contained FOH sound reinforcement system consisting of V-DOSC
enclosures and accessories, rigging hardware, SB218 subwoofers, approved digital signal processors
with OEM factory presets, L-ACOUSTICS LA48a power amplifiers, power amplifier racks, PADO2a
or PADO4a panels, CO6 or CO24 signal distribution panels, loudspeaker and signal distribution
cables. V-DOSC system elements have been carefully selected by L-ACOUSTICS for their specific
quality and long term reliability.
The benefits of a system standard include:
Cross rental compatibility between V-DOSC Network Partners
High standards of quality control
Consistent system performance worldwide
Reduced procurement time (no need to build panels, racks, etc)
Long term, common experience shared by QVTs and CVEs
Enhanced end user confidence (artist, FOH engineer, production)
The V-DOSC system standard does not include chain motors, mains distribution or external handling
gear, nor does it include upstream signal mixing and processing equipment. In general, the V-DOSC
system is capable of producing sound from a line-level signal in any concert situation.
System block diagrams are presented below to provide an overview of system connection and signal
flow. This is followed by an identification of the individual elements of the system and more detailed
descriptions in Sections 1.2 through 1.7.
Please note that specific multi-conductor connector selection for system drive remains open for the
user to define although L-ACOUSTICS does offer a specific connector type that is supplied with
turnkey systems. L-ACOUSTICS recognizes the fact that multi-conductor snakes and connectors
represent a significant investment and many users already have their own internal standard that they
must adhere to. Therefore, this part of the system standard remains flexible.
System elements that must remain standard in order to ensure compatibility include: digital signal
processors; OEM factory presets; channel assignments for signal distribution; power amplifiers; and
power amplifier rack panels.
General block diagram representations of V-DOSC system components, cabling and signal flow are
given below in Figures 6-8. Please refer to these block diagrams for a system overview.
NOTE: V-DOSC systems that do not comply with the system standard are considered non-approved by L-
ACOUSTICS. For the case of non-standard systems, L-ACOUSTICS does not accept responsibility for misuse
or misoperation and in some cases warranty coverage may be considered void.
L-ACOUSTICS strongly encourages all users to comply with the recommended standard as closely as
possible in order to maintain approved status.
