Lab.gruppen Brings Double Channel Density to its E Series of Commercial Install Amplifiers

Lab.gruppen has expanded its innovative and energy efficient E Series of compact 1U installation amplifiers with the introduction of the first four-channel models in the range, the E 10:4 and E 5:4, as well as the highly cost-effective new two-channel E 2:2. Now with a total of six models to afford integrators with unprecedented flexibility in system specification, the newly expanded E Series marks the 10th anniversary of Lab.gruppen's first major entry of 2U, 8 channel solutions for the commercial installation market with C Series in 2006.

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 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.
 

Lab.gruppen performance with Energy Star compliance

Lab.gruppen's IDEEA architecture secures full Energy Star compliance by combining net operating efficiency of greater than 80% with an auto-power-down feature. After 20 minutes with no input signal, the amplifier automatically switches to standby mode – with consumption of less than 1 W – and switches back on when an input signal returns. GPIO facilities enable third-party systems to remotely control and monitor power state via contact closure.
