AMP4150

Boost your 70/100 V in-line fixed installations with the AMP4150, the high-impedance amplifier that simplifies your installation projects.
Commercial facilities, schools, and public spaces require reliable sound systems capable of covering long distances, often with a large number of speakers distributed across zones that require different audio sources and volume levels. The AMP4150 meets these needs with four independent 150-watt channels in highly efficient Class D. With comprehensive protection features, a compact rack-mount design, and rear-panel volume controls for technician-only operation, this amplifier is designed to operate continuously without public intervention.

High-performance Class D.
The Class D amplifier delivers 4 × 150 W at 100 V with remarkable acoustic precision. The frequency response ranges from 20 Hz to 20 kHz, while harmonic distortion remains below 0.1% and the signal-to-noise ratio exceeds 100 dB. The thermoregulated thermal management system combines energy efficiency with electronics protection, ensuring safe, continuous operation.

Energy savings and cost reduction.
Auto Standby continuously monitors for an audio signal and automatically optimizes power consumption. After 15 minutes of inactivity, the amplifier switches to standby mode, drastically reducing its energy consumption and your electricity bills. The amplifier instantly returns to full power as soon as a new signal is detected. In installations that operate intermittently, this intelligent management generates substantial savings while reducing your carbon footprint and extending the device’s lifespan.

Simplified professional installation.
All inputs and outputs feature Euroblock connectors, ensuring secure and quick wiring. The essential controls (volume, high-pass filter, standby activation) are located on the rear panel, while the level and protection indicators remain visible on the front panel. The 2U rack-mount format integrates seamlessly into your equipment racks with intelligent ventilation that ensures quiet operation.
