Lab.gruppen launches E Series

AUTHOR: Inavate

Lab.gruppen officially launched its E Series of power amplifiers at PLASA in London. InAVate got a sneak preview of the product at InfoComm in June – watch the video in the main story.

The 1U power amplifier range was developed specifically for the installation market. It provides good power reserves with low power consumption.

It comprises three two-channel power amplifiers, all incorporating Lab.gruppen’s IDEEA (IntelliDrive Energy Efficient Amplifier) technologies. All are housed in 1U cabinets, weigh less than 5 kg (11 pounds), and feature universal power supplies.

Nominal output power ratings per channel (@ 4 ohms or 70 V) are 600 W, 400 W, and 200 W for, respectively, the E 12:2, E 8:2, and E 4:2. However, significantly higher per-channel outputs are possible with asymmetrical loading and proper setting of Lab.gruppen’s proprietary Rail Sensing Limiter (RSL).

The amplifiers are certified as Energy Star 2.1 compliant. In this respect, the power-to-current-draw ratio for burst signals with 1/8th average power is 400 W output for 1 A of line current at 120 V mains – a performance characteristic matched only by the PLM 20000Q. Control via third-party systems is enabled via GPIO.
