L-Acoustic LA24a 2-Channel Power Amplifier

$0.00

The LA24a is a compact, light-weight power amplifier (2 rack units high, 10 kg) designed for high performance touring and fixed nstallation. Capable of delivering over 1700 watts per channel into 2 ohms, the LA24a can also be configured to match the power delivered to a wide range of impedance loads using Minimum Load Select (MLS) switches. MLS flexibility allows the LA24a to be customized to suit a variety of L-ACOUSTICS loudspeaker models and applications. The switch-mode power supply (SMPS) employed in the LA24a is a modern solution to the weight and size problem. With SMPS technology, it is possible to use ferrite transformers instead of the heavy iron transformers and large electrolytic capacitors that are typical of conventional power amplifiers. Combined with the patented Intercooler® system, this results in a weight reduction of up to 60% when compared with conventional amplifiers of similar power ratings.

About the L-Acoustic LA24a 2-Channel Power Amplifier

The LA24a is a dedicated two-channel power amplifier conceived as an integral component within a complete, optimized sound reinforcement ecosystem, designed to deliver controlled, transparent power to specific passive loudspeaker systems. It embodies a system-oriented philosophy where the amplifier is not a generic component but is engineered in concert with the loudspeakers it is intended to drive. This synergy ensures that the amplifier's output characteristics, damping factor, and protection parameters are meticulously matched to the loudspeaker's load requirements, unlocking the full acoustic potential and designed performance of the system. The result is an amplification platform that provides exceptional control, particularly in the low-frequency range, contributing to tight, articulate bass response and overall sonic fidelity that is consistent and reliable.

Technologically, the LA24a incorporates a robust and efficient Class D power stage, capable of delivering substantial current to drive demanding low-impedance loads with stability. It features comprehensive thermal management and advanced protection circuitry that monitors output conditions in real-time, safeguarding both the amplifier and the valuable loudspeakers connected to it. The front panel provides clear, intuitive metering for real-time level monitoring of each channel, along with status indicators for signal, clip, and thermal conditions. Its connectivity is straightforward, with balanced analog inputs and robust output terminals, reflecting a design ethos that prioritizes sonic performance and reliability over extraneous features, making it a trusted workhorse for both touring and installation professionals who rely on this specific system synergy.

In application, the LA24a excels in providing clean, dynamic power for stage monitoring, front fill arrays, or compact main systems where its matched performance is critical. Its reliability and predictable behavior under load make it a preferred choice for audio engineers who require consistent performance show after show. The amplifier represents a commitment to a holistic approach to sound system design, where every element from the source to the speaker is considered as part of a cohesive whole. It offers not just amplification, but a guarantee of performance integrity, ensuring that the connected loudspeakers perform precisely as the system designers intended, with clarity, power, and resilience.
