- Legacy of rock-solid QSC amplifier dependability
The MP-A Series music and paging amplifier family builds on a 50 year legacy of QSC amplifier dependability and quality whileoffering an incredible amount of flexibility for business music and paging applications.
FlexAmp Technology
FlexAmp Technology simplifies system design by allowing a single high channel count amplifier to meet the needs of systems thatwould typically utilize multiple amplifiers of different power levels. It achieves this by allowing the installer to configure each pair ofchannels (e.g. ch 1-2, or 3-4, etc.) to deliver up to 400 W combined output power, in any mix. This makes for an amazing amount offlexibility, especially when paired with the output mode switch that offers settings for 4 Ω, 8 Ω, 70 V and 100 V. Additional capabilities of the MP-A series include an 80 Hz highpass filter available on each output, as well as a remote input for putting the amplifier into standby mode for firesafety systems and an amplifier status signal on the remote output for system verification.
Flexibility
For an example of versatility of the MP-A Series, imagine the MP-A40V in a typical restaurant scenario. Output A of the amplifier is set up for a 20 W 70 V load for a pair of ceiling loudspeakers in the bathrooms while output B is set up in 4 Ω mode for driving one or two Lo-Z subwoofers with up to 380 W. Output C is set up with the highpass filter engaged for driving 250 W into 70 V ceiling loudspeakers in the main dining room, whileoutput D is driving 150 W into 8 Ω surfacemount loudspeakers on the patio.
Power and Space Efficiency
MP-A Series amplifiers are extremely efficient with class-D output circuitry and switchmode power supplies. In addition, all models offer seamless Standby mode when not in use for 28 minutes and auto-ramp circuitry that ensures quiet and fast power up from Standby when signal is present. This combination of output topology and energy saving circuitry make for extreme efficiency and low operational costs. The 1RU chassis meansthat the MP-A Series amplifiers are perfect for installations with rack space restrictions.
