QSC MP-A40V 400W FlexAmp Hi/Lo-Z 4-Channel Amplifier, 4x 200W Power, Highpass Filter Per Channel
Image of 1
Key Features
- Flexible FlexAmp power lets you allocate up to 400 W per channel pair (4 x 200 W nominal) so zones and paging get exactly the power they need
- Class-D efficiency and switchmode power supply reduce energy use and operating cost for 24/7 security and monitoring installations
- Hi/Lo-Z load selector (4 Ω, 8 Ω, 70 V, 100 V) and selectable 80 Hz highpass per channel simplify integration with speakers and line‑level paging systems
- 1RU rackmount footprint and robust protections (overcurrent, short, thermal) save rack space and minimize downtime in AV racks and control rooms
- Auto-standby and remote control inputs reduce power draw while maintaining instant responsiveness for background music, paging, and surveillance announcements

MP-A40V
Overview
Built for flexible, reliable audio distribution in paging, background music and security monitoring environments, the QSC MP-A40V 4-channel pro amplifier delivers focused power and efficiency where you need it most. As a QSC professional amplifier, the MP-A40V uses FlexAmp technology to provide up to 400 W per channel pair (4 x 200 W nominal) so installers can route power dynamically between zones without wasting capacity. Class-D output circuitry and a switchmode power supply keep energy use and cooling requirements low—helpful for 24/7 surveillance, monitoring and control-room setups.
Integration is straightforward: a front-end load selector supports 4 Ω, 8 Ω, 70 V and 100 V loads, and each channel includes a selectable 80 Hz highpass filter to protect low-frequency drivers and improve voice intelligibility for paging and security announcements. The 1RU chassis saves rack space while comprehensive protections (overcurrent, short, thermal) and auto-standby maintain uptime. Ideal for AV integrators, security contractors and facilities managers, the MP-A40V pairs proven QSC reliability with power flexibility. Contact sales or add to cart to specify the MP-A40V for your paging, security or surveillance audio system.
