Technology Brief:
Class TD, Regulated SMPS (R.SMPS™), and Intercooler®
E Series: Dedicated Installation Amplifiers
Technical Data
▸ High power density – 2 x 200 W in 1U
▸ Certied Energy Star compliant
▸ Flexible – IntelliDrive delivers comparable power per channel at
70 V or Low-Z (2, 4, 8 and 16 ohms)
▸ Asymmetric loading – Allows “mixing and matching” of loads
with different impedances to maximize both overall system
efficiency and inventory utilization
TM
▸ IDEEA
output stage based on patented Class D variant
▸ High efciency – Extremely low power consumption and
heat output
▸ Auto-standby function – with power consumption < 1 W in
standby state
▸ Exceptionally low lifetime operating costs
▸ RSL switch – Innovative circuit senses rail voltage and optimizes
output for instantaneous load conditions
▸ Efcient cooling – One temperature-controlled fan
▸ Comprehensive circuit protection and fault indication
E Series, built around Lab.gruppen’s eco-friendly IDEEA: IntelliDrive Energy Efficient Amplifier
Specically designed for greater sustainability through “greener” commercial installations, E Series incorporates the latest advances in
Lab.gruppen quality and durability into a complete line of compact (1U) and highly cost-effective two- and four-channel ampliers.
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 conguration exibility, and an unprecedented
cost-benet ratio.
At the heart of E Series is Lab.gruppen’s IDEEA (IntelliDrive Energy
Efcient Amplier) technology. Based around a patented Class D
variant output stage, IDEEA produces high power levels with very
low distor tion 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 congurable 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.
Lab.gruppen performance with Energy Star compliance
Lab.gruppen’s IDEEA architecture secures full Energy Star compliance
by combining net operating efciency of greater than 80% with an
auto-power-down feature. After 20 minutes with no input signal, the
amplier 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.
