Details
The E Series incorporates the latest advances in Lab.gruppen quality and durability into this powerful, ultra-compact, and highly cost-effective two-channel amplifier.
Small in size, huge in benefits
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 IDEEA (IntelliDrive Energy Efficient Amplifier) technology. Based around a patented Class D output stage, IDEEA produces high power levels with very low distortion while drawing minimal mains current.E Series also introduces a proprietary Rail Sensing Limiter (RSLTM) which greatly reduces signal clipping, ensuring high quality audio output at all times, with user configurable output thresholds of either Hi-Z (70 V) or Lo-Z (40 V peak). The highly innovative RSL switch circuit senses rail voltages and optimizes output for instantaneous load conditions. RSL settings also facilitate asymmetric loading of the channels, to optimize performance and efficiency from each individual unit - allowing the total available output power to be utilized unequally between the channels, and even allowing for mono use, with all power on a single channel. This makes it possible, for example, to drive a small sub on one channel and a number of 70 V distributed ceiling loudspeakers on the other.
