LAB GRUPPEN E8:2 Power Amplifier 2 x 400 W

เครื่องขยายเสียง LAB GRUPPEN E8:2, มีกำลังขยาย 2 x 400 วัตต์ per channel at 70 V or Low-Z (4, 8 and 16 ohms), IDEEA™ output stage based on patented Class D variant, Auto-standby function, Comprehensive circuit protection

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.

To conform with Energy Star requirements, E Series amplifiers offer auto-power-down, which activates when no signal is detected for 20 minutes. Auto-power-on is triggered when signal is again present at the input. The GPI-type contact closure can also be used to control the power state as well as external power sequencers if desired.

E Series amplifiers are designed for ease of installation and reliable service, with notable features including a 35 Hz high-pass filter (switchable per channel), inputs and outputs on detachable Phoenix-type screw terminals, and a temperature controlled fan that turns off for low-level signals. Comprehensive circuit protection and fault indication also included.

Features:

  • High power density – 2 x 400 W in 1U
  • Certified Energy Star compliant
  • Flexible – IntelliDrive delivers similar 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 efficiency – 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
  • Efficient cooling – One temperature-controlled fan
  • Comprehensive circuit protection and fault indication
