Name: Lab Gruppen E 40:4 4 Channel Class D Power Amplifier, 4 x 1000W, 70V and Low Impedance, 1U Rack, Energy Efficient
Brand: Lab Gruppen

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. 4 × 1,000 WOutput power 4,000 WTotal output 2 Ω-100 VLo-Z and Hi-Z 1U19″ rack, 7.9 kg Features 4,000 W across 4 flexible output channels in a 1U form factor 4 × 900 W into 2 Ω; 4 × 1,000 W into 4 Ω, 8 Ω, 70 V or 100 V; 4 × 625 W into 16 Ω Asymmetric channel loading mixes different impedances on one amplifier Proprietary IDEEA Class-D output stage Rail Sense Limiter (RSL) greatly reduces signal clipping and simplifies configuration Low power consumption and heat generation ease demands on mains and cooling Auto-standby and auto-power-on cut consumption in non-operating cycles Built-in 50 Hz high-pass filter, switchable per channel on the rear panel Per-channel attenuation knob and signal LED on the rear panel for commissioning Temperature-controlled fan with front-to-back airflow Aluminium front panel with power, temperature and per-channel signal/limit LEDs GPIO connector with power control and indication for system integration Balanced analogue inputs and amplifier outputs on detachable screw terminals Comprehensive fail-safe circuit protection Specifications Amplifier channels4 Total output, all channels driven4,000 W Output per channel900 W into 2 Ω; 1,000 W into 4 Ω, 8 Ω, 70 V or 100 V; 625 W into 16 Ω Max output voltage per channel141 Vp / 100 Vrms Max output current per channel21.2 Arms THD (20 Hz - 20 kHz @ 1 W into 8 Ω)70 dB Frequency response2 Hz - 40 kHz Input impedance20 kΩ Common mode rejection50 dB Output impedance25 mΩ Mains100-240 VAC, standard IEC receptacle Power consumption1,000 W Standby consumptionShow more
