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
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.
