Oldal 1/2
▸High power density – 4 x 125 W in 1U
▸Certied Energy Star compliant
▸Flexible – IntelliDrive delivers comparable power per channel at
70 V or Low-Z (4, 8 and 16 ohms)
▸Asymmetric loading – Allows “mixing and matching” of loads
with different impedances to maximize system efciency and
inventory utilization
▸IDEEA™ output state based on patented Class D variant
▸Exceptionally low lifetime operating costs
▸High efciency – Extremely low power consumption and
heat output
▸Auto-standby function – Power consumption < 1 W in
standby mode
▸RSL Switch – Innovative circuit senses rail voltage and optimizes
output for instantaneous load conditions
▸Efcient cooling – Dual temperature-controlled fans
▸Comprehensive circuit protection and fault indication
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
efciency, output congurationexibility, and an unprecedented
cost-benet 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
efciency. 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 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.
