Lab.gruppen E 40:4 — compact 4-channel Class D installation amplifier from the Lab.gruppen E series, designed for efficient, high-density deployment in fixed installation audio systems across theatres, conference centres, and commercial venues.
The E 40:4 provides four independently configurable channels of amplification in a single 1U chassis. Lab.gruppen's IDEEA (IntelliDrive Energy Efficient Amplifier) Class D technology minimises heat output and power consumption without compromising audio performance. The proprietary Intercooler heatsink dissipates heat efficiently, allowing high channel density in tightly packed racks. Each channel includes selectable gain and filter settings for per-zone tuning. Both XLR and Speakon connectors are provided on the rear panel. Integrates with Lab.gruppen's CAFE (Configuring Amplifiers for the Environment) software for energy monitoring and system planning.
