field 2-channel PLMs
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. On 2-channel PLMs each power channel is available
from two pairs of binding posts.
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 chan-

nels 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 4 mm 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.
