Figure 10-8
Binding post versions of the PLM are fitted with
four pairs of black and red 4 mm binding posts. Each
pair provides the output from one power output
channel.
Connect the ‘+’ loudspeaker terminals to the red
binding posts and the ‘ – ‘terminals to the black
binding posts.
There are three methods of connecting to the binding
posts.
Solder 4 mm Banana plugs to the ends of the
▸
speaker wires and plug into the center of the
turrets.
Thread the stripped ends of the wires through
▸
the holes in the posts. Enter the wires for output
channels 1 and 3 from above and for channels 2
and 4 from below. Tighten the plastic turrets by
finger only – be careful not to overtighten.
Crimp 4mm insulated spade terminals onto the
▸
ends of the wires. These can be pushed into the
binding post assembly from above (Chs 1 and
3) or below (Chs 2 and 4). The hole in the post
is ignored. Hand tighten plastic turrets, being
careful not to overtighten.
The outputs of the PLM can produce a high
voltage. Do not connect or disconnect
loudspeaker(s) while the PLM is powered on. Never
operate the PLM with any portion of bare loudspeaker
wire exposed. On Speakon versions, do not use
mating plugs without the rear covers in place.

The network connections of the PLM are on two
Neutrik EtherCon RJ45 sockets. The second
connector may be used for linking multiple PLMs,
or alternatively for connection of a secondary network
for full redundancy.
The network connections on the PLM auto-sense
whether standard (‘straight’) or ‘crossed’ Cat-5e
cables are in use, and thus either type may be
used. Pre-made cables with moulded RJ45 plugs
are recommended. If it is necessary to make up
custom Cat-5e network cables, use the following
pinout:
When the PLM is connected to an active network,
the yellow LINK LED above the connector being
used illuminates. Data activity on the network is
indicated by illumination of the green ACT LED. It is
normal for the ACT LED to flicker either sporadically
or continuously.
Pin No.
