The MP-A20 power amplifier are designed for Background Music and Paging applications. With class-D output circuitry, a switch mode power supply with active PFC, and Auto-standby power saving, the MP-A20 offer high efficiency and low cost of ownership.
This amplifier provide a unique FlexAmp™ circuit topology that enables each pair of channels to deliver up to 400 Watts of total power in any ratio. This FlexAmp technology when combined with the ability to drive any type of output load (4 Ω, 8 Ω, 70 V, 100 V) ensures extreme flexibility. Other useful features of the MP-A20 include an 80Hz high-pass filter per channel, a remote standby contact, and amplifier status output for 3rd party system monitoring.
