Description
The MP-A Series music and paging amplifiers build on a 50-year legacy of QSC amplifier dependability and quality. The MP-A Series offers an incredible amount of flexibility for business music and paging applications, while maintaining high efficiency and low total cost of ownership.
Features:
- FlexAmp Technology allows each pair of amplifier channels to deliver up to 400 W total power, in any ratio
- Class-D output circuitry and switchmode power supply for high efficiency and low cost of ownership
- 1RU amplifier design for rack space savings
- Load selector for driving 4 Ω, 8 Ω, 70 V or 100 V on each channel
- Selectable 80 Hz highpass filter offered on each channel
- Power saving features - Auto-standby (after 28 minutes with seamless auto-ramp when signal returns) and remote standby input
- Amp status remote output
- Rock-solid QSC amplifier dependability
FlexAmp Technology
FlexAmp Technology allows each pair of amplifier channels to deliver up to 400 W total power, in any ratio.
Hi-Z / Lo-Z
Each channel can be quickly configured to drive 4 Ω, 8 Ω, 70 V or 100 V on each channel.
Highpass Filter
The MP-A Series includes switchable 80 Hz high-pass filter on each output channel.
Power Efficient
MP-A Series amplifiers are extremely efficient with Class-D output circuitry and switchmode power supply.
Space Efficient
MP-A Series come in a 1RU chassis and are perfect for installations with rack space limitations.
