The LAB Gruppen Lucia 120/1-70 is a compact, single-channel 120W power amplifier designed for high-impedance (70V/100V) distributed audio systems. It is part of the Localized Utility Compact Intelligent Amplification (LUCIA) series, which focuses on decentralized AV system design by placing power and processing closer to the speakers.
Key Specifications & Performance
- Power Output: Delivers 120W into 70V lines or 16-ohm loads, and 60W into 100V lines.
- Efficiency: ENERGY STAR qualified with an automatic standby mode that consumes less than 1W after 20 minutes of no signal.
- Form Factor: Half-rack 1U chassis (216 x 44 x 280 mm) weighing approximately 1.9 kg (4.2 lbs).
- Connectivity:
- Inputs: Two balanced 3-pin Euroblock terminals and two parallel unbalanced RCA connectors.
- Outputs: One 2-pin detachable screw terminal.
- Control: USB port for firmware and DSP configuration, plus a configurable GPIO port for remote level control or integration.
Advanced Processing Features
The unit includes an integrated digital front end with a 2 x 1 Mix Matrix and comprehensive DSP capabilities:
- Loudspeaker Presets: Pre-configured EQ filters for various loudspeaker models to simplify commissioning.
- Automatic Dynamic Loudness Contouring (ADLC): Adjusts performance to maintain audio quality at any output level.
- Protection Circuitry: Comprehensive safeguards against short circuits, thermal overload, and extreme low line voltage.
- Auto Load Sense: Automatically sets the Voltage Peak Limiter (VPL) based on the connected load for optimal performance.
