Q-SYS MP-A20V Flexamp Technology 400-Watt Amplifier - 2x 200-Watt
The MP-A Series music and paging amplifiers are a legacy of 50 years of amplifier dependability and quality. They offer amazing flexibility for business music and paging applications, while keeping high efficiency and low total cost of ownership.
The MP-A20V is a 2-channel amplifier perfect for background music and paging. It has Class-D output circuitry with a switch-mode power supply and active PFC. The FlexAmp circuit topology allows each pair of channels to deliver up to 400 Watts of total power in any ratio. This technology combined with the ability to drive any output load (4/8 ohms or 70/100V) ensures great flexibility.
Features:
- • FlexAmp Technology: Each pair of channels can deliver up to 400 W total power in any ratio, giving you ultimate control
- • Class-D output circuitry and switchmode power supply: High efficiency and low cost of ownership
- • 1RU amplifier design: Saves rack space
- • Load selector: Drive 4Ω, 8Ω, 70V or 100V on each channel
- • Selectable 80 Hz highpass filter: Offered on each channel for customization
- • Power saving features: Auto-standby (after 28 minutes with seamless auto-ramp when signal returns) and remote standby input
- • Amp status remote output: Keep track of the amplifier's status remotely
