E 12:2

Technology Brief:

Class TD, Regulated SMPS (R.SMPS™), and Intercooler®

E Series: Dedicated Installation Amplifiers

Technical Data

▸ High power density – 2 x 600 W in 1U

▸ Certied Energy Star compliant

▸ Flexible – IntelliDrive delivers comparable power per channel at

70 V or Low-Z (2, 4 and 8 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 efciency – 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

▸ Efcient 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

Specically 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 ampliers.

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 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 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.
