Lab Gruppen E 5:4 4-Channel Amplifier, 500W

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

• High power density – 4 x 125 W in 1U
• Certified Energy Star compliant
• Flexible – IntelliDrive delivers similar power perchannel at 70 V or Low-Z (4, 8 and 16 ohms)
• Asymmetric loading – Allows “mixing and matching” ofloads with different impedances to maximize both overall system efficiency andinventory utilization
• IDEEA™ output stage based on patented Class D variant
