คำอธิบาย

LAB GRUPPEN E2:2 Power Amplifier 2 x 200 W

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 × 200 W in 1U
Certified Energy Star compliant
Flexible – IntelliDrive delivers similar power per channel at 70 V and Lo-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
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
