LAB GRUPPEN E 40:4_US1 4000W Amplifier with 4 Flexible Output-Channels for Installation Applications (E 40:4_US1)

The E 40:4 boasts intelligent eco-friendly credentials, ensuring a low lifetime cost of ownership. Expanding upon Lab Gruppen's renowned legacy in tour-grade sonic excellence and unwavering durability, the E Series emerges as a game-changer in the installation market. It introduces an ultra-compact footprint, top-tier operational efficiency, output flexibility, and an unmatched cost-benefit ratio. Central to the E Series is Lab Gruppen’s pioneering IDEEA (IntelliDrive Energy Efficient Amplifier) technology. Anchored around a patented Class D variant output stage, IDEEA generates high-power levels with minimal distortion while drawing minimal mains current. Exclusive to the E Series, Lab Gruppen’s proprietary Rail Sensing Limiter (RSL™) significantly diminishes signal clipping, ensuring consistent high-quality audio output. Configurable for Hi-Z (70 V or 100 V) or Lo-Z, RSL dynamically senses rail voltages to optimize each output for instantaneous load conditions. These settings also facilitate the asymmetrical loading of channels, maximizing both performance and efficiency. Moreover, the total available output power can be intelligently allocated among the channels as per the application's demands, enabling scenarios like powering a small sub on one channel and multiple 70 V ceiling loudspeakers on another.

Flexible Asymmetric Loading

Maximize performance and efficiency on a per-unit basis, offering the flexibility to distribute the total available output power unevenly across channels or consolidate all power into a single channel for mono applications. This empowers you to effortlessly power a small subwoofer through one channel while commanding a series of 70 V distributed ceiling loudspeakers through the other channel.
