    About this Product

    The Lab Gruppen E 40:4 delivers 4 × 1,000 W, 4,000 W in total, from a single rack unit for installed sound. Built on the IDEEA Class-D platform with the Rail Sense Limiter, each channel runs Lo-Z loads down to 2 Ω or Hi-Z 70 V / 100 V constant-voltage lines, and asymmetric loading lets you mix subs, full-range pairs and long distributed ceiling runs across the four channels of one chassis. High efficiency keeps mains draw and heat low, easing demands on the installation’s power distribution and cooling.
