In designing the E Series, Lab.gruppen engineers drew upon the cutting-edge amplifier design philosophies developed for the flagship PLM™ 20000Q Powered Loudspeaker Management system, evolving these to create new circuit topologies and control features to meet the demands of 21st century AV installations. The result is a new amplifier platform called IDEEA: IntelliDrive Energy Efficient Amplifier. The principal design challenge was maintaining Lab.gruppen's impeccable sonic performance and robust power output while meeting – or exceeding – the rigorous efficiency requirements of Energy Star 2.1 certification. The challenge was met on two fronts: reducing current draw during operating cycles with vigorous program material and high output levels, and reducing power consumption during non-operational cycles.

Lab Gruppen E 10: 4 Features:

  • High power density – 4 x 250 W in 1U
  • Certified Energy Star compliant
  • Flexible – IntelliDrive delivers similar 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 both overall system efficiency and inventory utilization
  • IDEEA™ output stage based on patented Class D variant
  • Exceptionally low lifetime operating costs
  • High efficiency – 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
  • Efficient cooling – Dual temperature-controlled fan
  • Comprehensive circuit protection and fault indication

Lab Gruppen E 10: 4 Specifications:

  • Number of channels: 4
  • Total output all channels driven: 1000 W
  • Peak output voltage per channel: 100 V / 70 Vrms
  • Maximum output current: 14 Arms
  • Dimensions (W x H x D): 483 x 44 x 381 mm (19" x 1 U x 15")
