Lab.gruppen E 20:4 — compact 4-channel Class D installation amplifier from the Lab.gruppen E series, optimised for low-power fixed installation applications in small commercial and corporate environments where high channel density and quiet, efficient operation are priorities.

The E 20:4 offers four channels of Class D amplification with Lab.gruppen's IDEEA technology, minimising energy use and heat generation in always-on commercial environments. Rational Power Management (RPM) allows power to be allocated across channels symmetrically or asymmetrically to match the specific load requirements of each zone. Individual channel gain and filter settings allow per-zone audio tuning. Comprehensive protection circuits guard against overheating, overload, and short circuits. The lightweight 1U chassis integrates into standard rack enclosures. Suitable for churches, conference rooms, hospitality, and retail installations requiring a compact, efficient multi-zone amplifier.
