The Dv-Dosc System Standard - L-Acoustics dV-DOSC Operator's Manual

1. THE dV-DOSC SYSTEM STANDARD

dV-DOSC is a complete, self-contained FOH sound reinforcement system consisting of dV-DOSC
enclosures and accessories, rigging hardware, dV-SUB, SB118 or SB218 subwoofers, approved digital
signal processors with OEM factory presets, L-ACOUSTICS LA24a or LA48a power amplifiers, power
amplifier racks, PADO2a or PADO4a panels, CO6 or CO24/MD24 signal distribution panels,
loudspeaker and signal distribution cables. All dV-DOSC system elements have been carefully selected
by L-ACOUSTICS for their specific quality and long term reliability.
Benefits of the dV-DOSC standard include:
Cross rental compatibility compatibility between Certified dV-DOSC Providers
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 dV-DOSC system does not include chain motors, mains distribution or external handling gear, nor
does it include upstream signal mixing and processing equipment. In general, the dV-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 identification of the individual components of the system and more detailed
descriptions.
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; L-ACOUSTICS LA
power amplifiers; and power amplifier rack panels.
NOTE: dV-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.
