LAB GRUPPEN E 12:2_US1 1200W Amplifier with 2 Flexible Output-Channels for Installation Applications (E 12:2_US1)

The E 12:2 has smart green credentials delivering low lifetime cost of ownership.

Energy Star Qualified

This Energy Star-qualified product maintains remarkably low current draw even at high output levels and reduces power consumption during non-operational cycles. This combination allows Lab Gruppen's products to uphold exceptional sonic performance and powerful output while adhering to the stringent efficiency standards of the Energy Star certification.

Small in Size, Huge in Benefits

The E Series from Lab Gruppen builds upon its renowned reputation for exceptional sound quality and robust durability, introducing a compelling edge to the installation market. This series boasts ultra-compact sizing, high operational efficiency, versatile output configurations, and an unparalleled cost-benefit ratio. At the core of the E Series lies Lab Gruppen’s IDEEA (IntelliDrive Energy Efficient Amplifier) technology, centered around a patented Class D variant output stage. IDEEA delivers high power with minimal distortion, drawing remarkably low mains current. Exclusive to the E Series, Lab Gruppen’s Rail Sensing Limiter (RSL) significantly minimizes signal clipping, ensuring consistently high-quality audio output. The RSL settings, configurable for Hi-Z (70 V) or Lo-Z, detect rail voltages and optimize outputs for instantaneous load conditions. These settings support asymmetric loading, enabling optimization of performance and efficiency across channels. This flexibility allows the allocation of total output power among channels as per application requirements. For instance, driving a small sub on one channel while powering several 70 V ceiling loudspeakers on another.

Lab Gruppen Performance with Energy Star Compliance

Lab Gruppen’s IDEEA architecture ensures complete Energy Star compliance through a blend of operational efficiency exceeding 80% and an auto-power-down function. When no input signal is detected for 20 minutes, the amplifier seamlessly transitions into standby mode, consuming less than 1 W. Once an input signal is detected again, the amplifier reactivates automatically. Additionally, GPIO facilities enable third-party systems to remotely manage and monitor the power state using contact closure.

Smart Green Credentials with Our IDEEA Platform

The now-proven IntelliDrive Energy Efficient Amplifier (IDEEA) platform represents the latest evolution of our amplifier design philosophies, drawing from technologies in our flagship PLM Series, to create ingenious contractor solutions with supreme green credentials.

Flexible Asymmetric Loading

Optimize performance and efficiency from each individual unit - allowing the total available output power to be utilized unequally between the channels, or for mono use with all power on a single channel. Enables you to drive a small sub on one channel and a number of 70 V distributed ceiling loudspeakers on the other.
