Lab Gruppen E4:2ComercialAmplifier

Lab Gruppen E4:2 Commercial Amplifier is a high-efficiency, 2-channel Class D amplifier delivering 2 × 200 W power output, perfect for modern commercial AV installations requiring reliable and energy-efficient performance.

The Lab Gruppen E4:2 amplifier incorporates advanced design principles from the flagship D Series and PLM Powered Loudspeaker Management systems. Featuring the patented IDEEA (IntelliDrive Energy Efficient Amplifier) platform, it offers energy-efficient, low current draw operation ideal for 21st-century commercial AV environments.

Maintaining Lab Gruppen’s renowned sonic performance and robust power output, the E4:2 exceeds Energy Star 3.0 certification requirements by reducing current draw during high output and lowering power consumption when idle.

The amplifier includes a 50 Hz high-pass filter (switchable per channel), detachable Phoenix-type screw terminals for inputs and outputs, and a temperature-controlled fan that activates only at higher signal levels. Comprehensive circuit protection and fault indication ensure reliable 24/7 operation.

Its high-headroom universal power supply accepts mains voltages from 70 to 265 V at 50 or 60 Hz, preventing excessive current draw during peak bursts and maintaining headroom for sustained output with minimal distortion. The Class D output stage operates at over 90% efficiency and supports bridged operation, allowing one channel to deliver up to twice the rated power when the other channel is unused or lightly loaded.
