Lab.Gruppen E10:4 4-Channel Power Amplifier

Building on LAB GRUPPEN’s touring reputation for sonic excellence and rock-solid durability, E Series brings a competitive edge to the installation market by adding ultra-compact size, high operating efficiency, output configuration flexibility, and an unprecedented cost-benefit ratio. At the heart of E Series is LAB GRUPPEN’s IDEEA (IntelliDrive Energy Efficient Amplifier) technology. Based around a patented Class D variant output stage, IDEEA produces high power levels with very low distortion while drawing minimal mains current. LAB GRUPPEN’s proprietary Rail Sensing Limiter (RSL™), also exclusive to E Series, greatly reduces signal clipping to ensure high quality audio output at all times. User configurable for Hi-Z (70 V) or Lo-Z, RSL senses rail voltages and optimizes each output for instantaneous load conditions. RSL settings also facilitate asymmetric loading of the channels to optimize performance and efficiency. Total available output power can be allocated among the channels as required by the application. This makes it possible, for example, to drive a small sub on one channel, a number of 70 V ceiling loudspeakers on the second channel, and a pair of full-range low impedance loudspeakers on the two remaining channels.

Features

• 1000 W amplifier carrying 4 flexible output channels in a high power density 1 rack unit form factor saves rack space and system cost
• Flexible IntelliDrive permits delivering the 4 x 250 W at constant voltage 70 V or low impedance (2, 4, 8 and 16 Ohms) on any channel
• Asymmetric channel loading allows mixing and matching loads with different impedances to maximize overall system efficiency and inventory utilization
• Comprehensive fail safe circuit protection ensures continued operation even under reduced operating conditions
