The L-Accoustics LA 15a is a state-of-the-art, four-channel power amplifier designed for professional use in both touring and fixed installations. Weighing just 8.6 kg and occupying only 2 rack units, this amplifier delivers a robust 600 watts per channel into 4 ohms. It's specifically engineered to amplify the high frequency section of multi-channel monitor systems or passive 2-way systems, making it an ideal selection for distributed installations. Additionally, the LA15a can power active 2-and 3-way systems through bridged connection of one or two channel pairs. It incorporates Minimum Load Select (MLS) switching technology, allowing it to adjust the output power to match various impedance loads effectively. The LA15a uses a cutting-edge switch-mode power supply (SMPS) that significantly reduces the weight and size traditionally seen in power amplifiers.

This SMPS makes use of lighter ferrite transformers replacing the bulky iron ones and utilizes large capacitors, contributing further to its lightweight profile. Furthermore, the patented Intercooler system enhances the heat dissipation, allowing this amplifier to perform efficiently under demanding conditions. The combination of these advanced technologies results in an amplifier that is up to 60% lighter than traditional models with comparable power outputs, offering enhanced portability and ease of installation without sacrificing performance.
