Galaxy Audio LA4/LA4PM - Manual (Page 5)

The LA4PM is an unpowered permanent mount Line Array
speaker designed for 70 volt systems. It features an internal
100 watt, 70 volt autoformer and a screw terminal block on
the back panel for selecting the proper wattage tap. Simply
connect the common (-) line from the amplifier to the screw
terminal labeled “COM”. Then connect the positive (+) line
from the amplifier to the screw terminal corresponding to the
desired wattage tap. A 16 ohm terminal is also provided to
bypass the autoformer and connect directly to the speakers
if desired. When using the 16 ohm terminal remove the
jumper clip that connects the 16 ohm terminal to AF+
terminal. The LA4PM may be wall mounted using an optional
bracket or “flown” from cables using the various threaded T-
nut locations on the cabinet. To use the
T-nuts, simply remove the threaded
plastic plugs using a small flat blade
screwdriver. To prevent air leaks, leave
the plastic plugs in any unused T-nuts.
