L-Acoustics LA12X
LA12X is a four-channel amplified controller designed to
power the largest loudspeakers in the L-Acosutics catalog.
LA12X features a proprietary switch mode power supply
(SMPS) with DSP-controlled power factor correction (PFC)
capable of delivering 12,000 watts of output power with
record hold times.
The universal SMPS (100 – 240 V) allows worldwide operation of LA12X with identical performance while the PFC grants
a high tolerance to unstable mains with low power consumption. The 4 x 4 architecture offers both flexibility to power a
high density of passive loudspeakers and a powerful amplfiication for large format active enclosures.
