QPS Series products are high-performance, versatile power
amplifiers for both touring and install applications, using
sophisticated Class-HD topology with four single-channel
outputs or one/two bridged outputs, parallel or stereo for up
to 4 x 2500 W (QPS 10K) and up to 4 x 1500 W (QPS 6K) at
2 ohms. It features independent gain control, signal/clip and
faults indicators, channels A and C XLR output link, parallel and

bridge mode, and speakON output connectors. Three dip-
switches allow setting the maximum output voltage peak for

each channel among eight values. High-e!ciency heat sinks and
variable-speed fans can withstand the hardest heat conditions
ensuring great power output stability over time. High quality, low
distortion audio output, flawless reliability, and industry-standard

speakON connectors make QPS series electronics the hassle-
free solution for sound systems and permanent installation

applications.

HD DESIGNED DRIVING POWER
Our HD amplifier technology features a very e!cient power
section with great care of the power output musicality,
maintaining a natural and clear sound at all frequencies, with
smooth highs and a tight, high-impact low end. The power
supply rails continuously track the input signal for remarkable
signal purity while preserving the high e!ciency of the Class-D
design. QPS amplifiers are bridgeable and maintain high
reilability with complex loads as low as 2 ohms nominal.
