Specifically designed for greater sustainability through “greener” commercial installations, 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 Lab.gruppen performance with Energy Star compliance Building on Lab.gruppen’s touring reputation for sonic excellence Lab.gruppen’s IDEEA architecture facilitates Energy Star 3.0 and rock-solid durability, E Series brings a competitive edge compliance by combining net operating efficiency of greater than to the installation market by adding ultra-compact size, high operating 80% with an auto-power-down feature. After 20 minutes with no input efficiency, output configuration flexibility, and an unprecedented signal present, the amplifier automatically switches to standby mode – cost-benefit ratio. At the heart of E Series is IDEEA (IntelliDrive Energy reducing power consumption to less than 1 W – and switches back on Efficient Amplifier) technology. Based around a patented Class when an input signal returns. GPIO facilities enable third-party systems D output stage, IDEEA produces high power levels with very low to remotely control and monitor power state via contact closure. distortion while drawing minimal mains current.
