WIRING
The IA 402D amplifiers use 4-pin Phoenix terminals and speakON® NL4 and connectors to output audio
signals, being the later the most recommended option. Equally, L-Line loudspeakers use speakON® NL4
connectors to input and pass amplified audio signals. These wires should be connected as shown below:

As detailed in the L-Line User Manual – Loudspeakers, L 35/R units include on the rear a switch to select the
source of the input signal from the NL4 connector, namely pins 1+/1- or 2+/2-. The signal chosen is the one
delivered to the transducers.
With a single NL4 cable, it is possible to send independent signals to L 35 FS and/or L 35 units in
the same array. Then, the input switch on each unit allows to select the pins carrying the signal
it must reproduce.
Finally, IA 402D amplifiers can input and link audio signals through XLR-3 connectors. They follow the next
plug-in and configuration scheme:

Wiring Scheme
It is recommended to use cables with at least 18 AWG conductor size. For long cable lengths, the maximum
conductor size is 14 AWG. Those wires must be assembled by a qualified technician.

In addition, the term L 35/R refers to both versions of L 35: L 35 indoor or L 35 R outdoor version.
Correspondingly, L 35 FS/R indicates the indoor and outdoor versions of the flysubs.
