LAB GRUPPEN E 8:2_US1 800W Amplifier with 2 Flexible Output-Channels for Installation Applications (E 8:2_US1)

The E 8:2 has smart green credentials delivering a low lifetime cost of ownership. 

Energy Star Qualified

Our Energy Star qualified products achieve impeccable Lab Gruppen sonic performance and robust power output while adhering to the stringent efficiency standards of Energy Star certification. They maintain exceptionally low current draw even at high output levels during operation and minimize power consumption during non-operational cycles. This balance ensures optimal performance while meeting the rigorous efficiency demands of Energy Star certification.

Small in Size, Huge in Benefits

Leveraging Lab Gruppen’s renowned reputation for exceptional sonic quality and enduring durability in touring, the E Series takes a significant leap into the installation market, offering an edge through its ultra-compact design, heightened operational efficiency, versatile output configurations, and an unmatched cost-benefit ratio. At the core of the E Series lies Lab Gruppen’s pioneering IDEEA (IntelliDrive Energy Efficient Amplifier) technology. Utilizing a patented Class D variant output stage, IDEEA achieves remarkable power output with minimal distortion while drawing minimal mains current. Exclusive to the E Series, Lab Gruppen’s Rail Sensing Limiter (RSL) plays a critical role in mitigating signal clipping, ensuring consistent high-quality audio output. Configurable for Hi-Z (70 V) or Lo-Z, RSL dynamically senses rail voltages, optimizing each output for immediate load conditions. This capability extends to asymmetric channel loading, optimizing both performance and efficiency. Additionally, the total available output power can be intelligently distributed among the channels, enabling scenarios such as powering a small sub on one channel and multiple 70 V ceiling loudspeakers on another.

Lab Gruppen Performance with Energy Star Compliance

Lab Gruppen's IDEEA architecture ensures complete Energy Star compliance by merging an operational efficiency exceeding 80% with an auto-power-down function. When idle for 20 minutes without an input signal, the amplifier seamlessly transitions into standby mode, consuming less than 1 W, and swiftly reactivates upon detecting a new input signal. Further enhancing its functionality, GPIO facilities empower third-party systems to remotely monitor and control the power state through contact closure. This level of control enables seamless integration and monitoring within broader operational systems, ensuring optimized energy usage and operational efficiency.

Smart Green Credentials with Our IDEEA Platform

The established IntelliDrive Energy Efficient Amplifier (IDEEA) platform stands as the pinnacle of our amplifier design evolution. It incorporates technologies from our flagship PLM Series, culminating in ingenious contractor solutions distinguished by their exceptional environmental sustainability and groundbreaking performance.

Flexible Asymmetric Loading

Maximize the performance and efficiency of each unit by offering the flexibility to distribute the total available output power unevenly between channels or consolidate all power into a single channel for mono applications. This versatility allows you to effortlessly power a small subwoofer on one channel while driving multiple 70 V distributed ceiling loudspeakers on the other channel, catering to your specific audio needs.
