Advanced DSP Processing: The Lab Gruppen LUCIA-240-2 integrates comprehensive onboard DSP, providing high-pass filters, parametric EQ, multi-band compression, and look-ahead limiting. This robust DSP capability ensures precise audio processing and customization, allowing for optimized sound quality and performance in various settings. The software for configuration, available for both Windows and Mac, simplifies initial setup and advanced adjustments via USB.

Energy Efficiency: Certified with ENERGY STAR, the LUCIA-240-2 is designed with energy efficiency in mind. It automatically transitions to standby mode after 20 minutes of inactivity, consuming less than 1 watt. This feature significantly reduces running costs and minimizes environmental impact while maintaining exceptional performance.

Automatic Dynamic Loudness Contouring: The amplifier includes Automatic Dynamic Loudness Contouring (ADLC), which adjusts the audio output for consistent sound quality across different volume levels. This technology ensures a balanced listening experience, even at low levels, enhancing overall audio clarity and comfort.

Enhanced Bass Profile: The LUCIA-240-2 features an Enhanced Bass Profile that extends low-frequency response, which is particularly beneficial when using smaller loudspeakers. This enhancement improves the depth and richness of the sound, making it suitable for various audio applications.

Auto Load Sense Technology: The Auto Load Sense technology in the LUCIA-240-2 detects the impedance load on each channel and self-configures the Voltage Peak Limiter (VPL) for optimal performance. This innovation allows the amplifier to deliver maximum power output across all loads, making it adaptable to a wide range of loudspeaker configurations.

Compact and Efficient Design: Featuring a Class-D amplifier, the LUCIA-240-2 offers low distortion and minimal heat generation. Its compact, half-rack 1U chassis allows for discreet installation in various environments. The included bracket supports easy wall-mounting, while the intelligent fan control ensures quiet operation.

Versatile Connectivity: The amplifier provides balanced analog inputs and outputs on detachable screw terminals, along with parallel unbalanced RCA connectors. The configurable GPIO port enables remote control for channel switching and level adjustments, while the RS232 interface allows for integration with third-party control systems.

Robust Protection Features: To ensure reliable operation, the LUCIA-240-2 includes comprehensive circuit protection, covering short circuit, thermal overload, and undervoltage conditions. These protections safeguard both the amplifier and connected loudspeakers, maintaining performance and longevity.
