W8LC and W8LCD Quick Start Guide
Important note:
This information assumes the reader is an experienced sound system technician who is familiar
with high quality, low noise system design and works to the internationally recognized
93/68/EEC Low Voltage Directive for mains safety. All rack systems should be fully PAT
(Portable Appliance) tested for electrical safety before use.
What would a typical W8LC rack look like?
Can I paralle l drive W8LC cabinets?
Yes. In normal systems W8LC cabinets are paralleled in pairs at the
loudspeaker column using short link cables. All W8LC sections are 8 ohms.
Each cable sees a two-speaker load so cables must be rated for a 4 ohm load.
See cable recommendations later.
In theory it is possible to drive more than two cabinets in parallel using
MA2.8S power amplifiers but sonic performance could suffer for the following
reasons:
1)
The rack mains current demand may cause mains voltages to drop or
exceed the breaker ratings. The former would reduce sound quality, the latter
would mute whole system sections.
2)
Band zoning (the progressive shelving control applied to the upper mid &
high frequency sections of line array columns to partially compensate for air
absorption) will be in coarser steps. Coverage won't be as smooth.
