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