Based around a patented Class D variant output stage, IDEEA produces high power levels with very low distortion while drawing minimal mains current.\u003c\/p\u003e\n\u003cp\u003eLab 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 100 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFlexible Asymmetric Loading\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOptimize performance and efficiency from each individual unit - allowing the total available output power to be utilized unequally between the channels, or for mono use with all power on a single channel.
