circuits of traditional QSC amplifiers to produce an
amplifier with incredible audio performance,
reliability, and thermal capacity. A special “High
Voltage” output circuit provides maximum power at
16, 8, 4 ohm loads. The PowerLight 1.6

HVX

is rated at
725 watts/channel into 8 ohms and 1100 watts/
channel into 4 ohms for the low frequency channel,
making it ideal for powering stage monitors and any
high power, bi-amplified speaker systems.

PowerWave Switching Technology
provides increased power supply
regulation to maintain excellent low
frequency response to 20 Hz.
Outstanding audio performance and
reliability, networkability, and light
weight make this amplifier ideal for all
critical sound system applications.
