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
efciency, output conguration exibility, and an unprecedented
cost-benet ratio.
At the heart of E Series is Lab.gruppen’s IDEEA (IntelliDrive Energy
Efcient Amplier) 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 congurable 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
efciency. 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.
Lab.gruppen performance with Energy Star compliance
Lab.gruppen’s IDEEA architecture secures full Energy Star compliance
by combining net operating efciency of greater than 80% with an
auto-power-down feature. After 20 minutes with no input signal, the
amplier 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.
