binding posts
In this version, the power outputs for loudspeaker
connection are available on four separate pairs of
fully-enclosed binding posts.
speakon connectors
In this version, the power outputs are simultaneously
available on a single 8-pole Neutrik Speakon
connector, and on two 4-pole Neutrik Speakon
connectors. The two 4-pole connectors carry the
outputs of channels 1 & 2 and 3 & 4 respectively.
The table below shows the proper wiring scheme
for these Speakon outputs.

6.2.3 Network connectors

The two Neutrik RJ45 EtherCon
permit integration into an Ethernet control network
encompassing multiple PLM Series units as well as a
PC running the DLC PLM Edition software. Network
connection permits full control of all PLM functions,
and monitoring of all PLM operating parameters, from
a remote position. The PLM Series also supports
the Dante audio networking protocol, which allows
transmission of multichannel, high-definition digital
audio over the same Ethernet connection.
The Ethernet ports automatically switch to
operate at the two standard Ethernet data
rates of 10Base-T and 100Base-T, and also
allow either "crossed" or "straight" network
cables to be used. Two LEDs above each port indicate
connection to a valid network (LINK) and network
activity (ACT).

Full information on how to connect the PLM to a
network is contained within a separate document,
the PLM Series Network Configuration Guide.
Primary connector
Use this connector when the network is a simple
"star" configuration, consisting of individual Cat-5e
connections between PLMs and a local Ethernet
switch. Alternatively it can be used to connect to
the Secondary connector of another PLM within a
network, thus forming a daisy-chain topology.
secondary connector
The secondary network connector can be used as a
loop-through to daisy-chain multiple PLMs into the
network. Alternatively, system security can be greatly
increased by using a dual-network topology. In this
case, the Secondary connector is connected to an
alternative Ethernet distribution system employing
a second set of switches, thereby ensuring full
redundancy and no single point-of-failure in the case
that Dante is used and a switch or cable fails. Further
information on PLM network configurations can be
found in the PLM Series Network Configuration
Guide.
When connecting multiple PLMs to an
Ethernet network, care must be taken NOT
to create a ring (closed loop) with the PLM
Ethernet ports. Ethernet by default will not
support a ring topology; creating a ring will cause the
network to malfunction.

6.2.4 AC input

Mains connector
AC input to the PLM is via a Neutrik PowerCon
connector, rated at 32 A.
