PN/LA Self-Powered Systems
PN/LA modules are self-powered with the PN-1 PowerNet Amplifier. The Class A/B amplifier section and the
Loudspeaker Specific Processing electronics require appropriate AC power. Audio inputs are high-CMRR analog
audio inputs with XLR looping connectors. If the R-Control remote supervision network is installed, connections
can be made via a separate twisted pair cable and Phoenix connector.
Source Signal
Source signal connections to a PN/LA array are quite straightforward, unless you intend to use level shading as
part of your array design. Connecting analog signal simply requires one cable from the top module to the snake.
Subsequent modules can be connected using the PN-1’s looping XLR inputs and outputs. Of course, if you intend
to use level shading as part of your array design, you will need to attenuate the inputs to all modules that receive
different signal levels.
Optional CobraNet Connections
The optional Renkus-Heinz CobraNet Breakout Box provides a very simple way to add CobraNet connectivity
to the system. Each Breakout Box can supply signal for up to six modules.
PNX/LA Externally-Powered Systems
PNX Amplifier Selection
PNX/LA array modules are bi-amplified. For optimum performance we recommend the X12 Controller and the
following power amplifier ratings:
LF 400 to 800 watts, RMS @ 16 Ohms
HF 80 to 160 watts RMS @ 16 Ohms
