Amplify your fixed 70/100 V line installations with the AMP4150, the high-impedance amplifier that simplifies your installation projects.
Commercial installations, schools and public spaces require reliable sound systems over long distances, often with a large number of loudspeakers distributed in zones requiring differentiated sources and volumes. The AMP4150 meets these needs with four independent 150 W high-efficiency Class D channels. Full protection, compact rack format, rear panel volume controls for technician-only management: this amplifier is designed for continuous operation without audience intervention.
High-performance Class D
Class D amplification delivers 4 × 150 W at 100 V with outstanding acoustic precision. Frequency response extends from 20 Hz to 20 kHz, while harmonic distortion remains below 0.1% and the signal-to-noise ratio exceeds 100 dB. Thermo-regulated thermal management combines energy efficiency and electronics protection, ensuring continuous, safe operation.
Save energy and reduce costs
Auto Standby constantly monitors the presence of the audio signal and automatically optimizes power consumption. After 15 minutes of inactivity, the amplifier switches to standby, drastically reducing energy consumption and your electricity bills. When a new signal is detected, the amplifier instantly returns to nominal power. In installations with intermittent operation, this intelligent management generates substantial savings while reducing your carbon footprint and extending the life of the device.
Professional installation made easy
Euroblock connectors are fitted to all inputs and outputs, guaranteeing fast, secure wiring. Essential controls (volume, high-pass filter, standby activation) are located on the rear panel, while level and protection indicators remain visible on the front panel. The 2U rack format integrates naturally into your technical bays, with intelligent ventilation that preserves acoustic discretion.
