The QSC MP-A40V is a compact four-channel installation amplifier from the MP-A Series, featuring FlexAmp technology and Class-D output for efficient music and paging systems. In a single rack unit, it drives low-impedance (4/8 ohm) or constant-voltage (70V/100V) loudspeakers, making it ideal for retail, restaurants, offices and background-music/paging applications.
Key Features
- Four channels delivering 200 W each at 4 ohm, 8 ohm, 70V or 100V (per-channel load selectable)
- FlexAmp technology lets each channel pair share up to 400 W total in any ratio (800 W total)
- Class-D output with switch-mode power supply for high efficiency
- Selectable 80 Hz high-pass filter and DIP-switch operating modes per channel
- Auto-standby with signal-sensing auto-ramp; remote standby and status outputs
- Compact 1RU chassis with thermally regulated forced-air cooling
The MP-A40V provides flexible, energy-efficient amplification for multi-zone installed sound without network dependency.
