LAB GRUPPEN LUCIA 240/1-70 Power Amplifier 1×60 W into 70 V/100 V
เครื่องขยายเสียงสำหรับระบบประกาศ LAB GRUPPEN LUCIA 240/1-70, 1 x 240 W into 70 V/100 V1, Class D amplifier, Built-in 2×1 matrix, Automatic Dynamic Loudness, DSP automatically, RS232 – Remote control and monitoring
LUCIA 240/1-70 has been designed and engineered for quick installation and easy setup. The supplied wall-mount bracket enables discreet on-wall location (such as behind video displays), but the ultra-compact form factor also allows easy placement virtually anyplace – whether next to a projector or integrated into a reception counter, podium & lectern or bar area. All input and output connections are on Euroblock screw terminals (with parallel unbalanced RCA connectors), and level setting is available on front-panel potentiometers. Advanced circuitry protects the amplifier and connected loudspeakers from potential damage caused by clipping, thermal overload, or extreme low line voltage.
The LUCIA 240/1-70 incorporates a digital front end with a 2 x 1 Mix Matrix and comprehensive DSP features, including proprietary Automatic Dynamic Loudness Contouring (ADLC™) and a full selection of EQ filters both before and after the matrix – features that eliminate the need for external mixers and processors in many applications, saving time and money. A software wizard facilitates fast setup, while the advanced editor allows offline configuration of common presets that can be quickly downloaded to multiple units via USB.
Features:
- Designed for constant voltage applications – 1 x 240 W into 70 V/100 V1
- Built-in 2×1 matrix – Mix two sources to mono or use for source selection
- Comprehensive DSP features – Per channel presets for high-pass filter, parametric EQ, multi-band compressor, and look-ahead limiter
- Automatic Dynamic Loudness Contouring™ – DSP automatically adapts to optimize performance at any output level
- Optimized presets – Available for specific loudspeaker models
- Configuration software – Windows and Mac software wizard for initial set-up (connection via USB)
- GPIO – Remote control for output level and instant wake from sleep mode as default; other options possible via the configuration software
- Compact form factor – Half-rack, 1U chassis and supplied bracket for flexible mounting
- Efficient Class D amplifier – Patented design for low distortion and minimal heat dissipation
- Fail-safe operation – Comprehensive short circuit, thermal and under-voltage protection
- Intelligent fan control – Silent at idle and extremely quiet at low output levels
- Selectable high-pass filter – Rear switches for ON/OFF and 50 Hz or 80 Hz filter; this is in series with the customizable input and output EQs (which are flat from the factory)
- ENERGY STAR® qualified1 – Conforms to latest energy efficiency standards
- RS232 – Remote control and monitoring from third party control solutions
***The peak voltage is 100 V, but the look-ahead limiter solution ensures that it cannot clip, so in real life use with music or speech it will typically be able to sustain a higher SPL in 100 V applications than 100 V amplifiers with higher peak voltage capability as the amplifier have the capacity to handle peaks way beyond “clip” without sounding harsh.
