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.

High-performance architecture
This mono amplifier delivers 1100 W at 100 V with full bandwidth from 20 Hz to 20 kHz. Harmonic distortion remains below 0.1% and the signal-to-noise ratio exceeds 100 dB, guaranteeing faithful reproduction and maximum intelligibility. Thermo-regulated fan cooling adapts in real time to thermal constraints, keeping the electronics in their optimum range without generating noise pollution.

Energy-saving Auto Standby
After 15 minutes without signal, the amplifier automatically switches to Auto Standby mode to limit power consumption. Resumption is instantaneous as soon as an audio stream is detected, with no perceptible delay or interruption. This autonomous function significantly reduces the energy bill of intermittent installations, while helping to extend component life.

Simple rack integration
Euroblock terminal blocks provide reliable and fast input and output connections. The volume control and HPF high-pass filter remain confined to the rear panel, preserving the integrity of installer settings. Four front LEDs (Signal, -20 dB, Clip, Protect) keep you constantly informed of operating status. With a weight of 7.8 kg and a standard 2U format, the amplifier fits into any existing technical cabinet.

Controlled power, minimal heat
Thanks to its Class D technology, this amplifier delivers 4 × 300 W at 100 V with exceptional energy efficiency and low heat emission. The audio spectrum covers the entire 20 Hz-20 kHz range, with harmonic distortion kept below 0.05% and a signal-to-noise ratio in excess of 100 dB. The thermostatically-controlled fan adapts its speed to the actual thermal load, ensuring stability and longevity without parasitic noise.

Automated power management
Intelligent standby mode detects the absence of signal for 15 minutes and automatically reduces the amplifier’s power consumption. This continuous monitoring of the audio flow optimizes energy expenditure without compromising responsiveness: the device instantly resumes nominal operation as soon as a signal is present. A decisive advantage for controlling long-term operating costs while limiting environmental impact.

Integrated installer configuration
Each channel has its own volume control and switchable high-pass filter (Flat/HPF 80 Hz), accessible only from the rear panel. Euroblock terminals on all links facilitate wiring and enhance connection reliability. On the front panel, four LEDs per channel (Signal, -20 dB, Clip, Protect) provide immediate visual diagnostics. The standard 2U rack chassis houses the electronics in a compact format weighing just 6.7 kg.
