Parallel Wiring Mode:
Powering subwoofers in parallel mode with one subwoofer per amplier channel provides opmum exibility for im-
plemenng cardioid subwoofer conguraons and Electronic Delay Steering (EDS) as well as an opmum 4-ohm load
for power amplier channels. This wiring method allows for greater design and control exibility since each VTX enclo-
sure is connected to its own amplier and DSP channel. Parallel wiring also makes tesng easier since each subwoofer
can be tested independently.
In this conguraon a breakout cable or a rack I/O panel is necessary to wire the two subwoofer transducers to one
amplier channel. These adapter cables are easy to construct out of stock connectors and cables. The pin conguraon
is provided later in this document.
