Lab Gruppen E8:2CommercialAmplifier

Lab Gruppen E8:2 Commercial Amplifier is a high-efficiency 2-channel Class D amplifier delivering 2 × 400 W power output, perfect for modern AV installations requiring reliable, energy-efficient performance.

Overview

The Lab Gruppen E8:2 amplifier utilises the advanced IDEEA (IntelliDrive Energy Efficient Amplifier) platform, derived from the flagship D Series and PLM Powered Loudspeaker Management systems. It combines exceptional sonic performance with robust power output while meeting stringent Energy Star 3.0 efficiency standards.

Designed for 24/7 reliable operation, the E8:2 features 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 safe and dependable service.

Advanced Power Supply and Output Stage

The amplifier includes a high-headroom universal power supply compatible with mains voltages from 70 to 265 V at 50 or 60 Hz. Its high storage capacity prevents excessive current draw during peak bursts, maintaining headroom for sustained maximum 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 its rated power when the other channel is unused or under low load.

Rail Sensing Limiter (RSL) Technology

Lab Gruppen’s proprietary Rail Sensing Limiter (RSL) optimises amplifier output for connected loads. Each channel features a two-position switch for low impedance or high impedance (70 V) loudspeaker systems, maintaining +4 dBu sensitivity regardless of load. This enables asymmetric loading, maximising power utilisation across channels.

Flexible Power Control

The E8:2 supports auto-power-down after 20 minutes of no signal and auto-power-on when signal returns, complying with Energy Star requirements. Additionally, a GPI-type contact closure allows external control of power state and integration with power sequencers.
