Our Adamson E-Racks are equipped with two Lab Gruppen PLM 20K44 SP amplifiers, featuring Lake processing and Dante™ audio networking functionality, and supplying up to 40,000 watts of output power per rack.


Our Adamson E-Racks are equipped with two Lab Gruppen PLM 20K44 SP amplifiers, featuring Lake processing and Dante™ audio networking functionality, and supplying up to 40,000 watts of output power per rack. The Adamson E-Rack also features serial redundant digital and analogue inputs, automatically switching to the next in series if signal is lost at the primary input.

Audio Panel
The 19”, 2U Adamson Audio Panel is comprised of XLR in and thru connections (analog or AES/EBU), etherCON RJ45 connections (Dante™ and control) and both Speakon™ NL8 and Socapex output connections. Jumping signals from rack to rack is simple, and even Dante™ signals can be distributed to up to 3 E-Racks without the use of an additional switch.

AC Panel
The AC Panel has 32 A 3-phase input and link connections, three hard-wired 32 A Powercon™ connections, as well as auxiliary power plugs.

Cisco SG300-20 Switch
The SG300-20 exceeds the performance benchmark set by Audinate. Adamson has adopted its use along with specific configurations designed to optimise transmission of Dante™ signals and Lake control data.

The Lab Gruppen PLM 20K44 Combines a 4-In, 4-Out Configuration With Industry-Standard Dante Networking, Setting The Benchmark For Powered Loudspeaker Management System.

The PLM 20K44 is the natural successor of the proven, road tested, and trusted LAB GRUPPEN touring foundation exemplified by the iconic PLM 20000Q. Now offering an extended 4-in, 4-out configuration together with twice the processing power via the latest version 6.3 Lake Controller release, plus industry-standard Dante® networking, the PLM 20K44 sets the benchmark for Powered Loudspeaker Management Systems.

The Power of LAKE Processing
The PLM 20K44 features the legendary power of exclusive LAKE Processing algorithms, incorporating four full-featured LAKE modules with four discrete channels of audio throughput input to output. Audio signals are selectable from four channels of analog (with Iso-Float ground isolation), four channels via AES3 digital inputs and eight dual redundant Dante networked digital inputs. Input signals are individually selectable for each channel, with programmable failover to a lower prioritised input.

CAFÉ for Green Credentials
CAFÉ (Configuring Amplifiers For the Environment) is a software suite that allows the PLM 20K44 to be easily configured and monitored in the most efficient manner possible. In addition to providing comprehensive system surveillance and configuration of amplifier features such as ISVPL and Breaker Emulation Limiter (BEL), CAFÉ also includes valuable help to save the environment. CAFÉ can accurately predict estimations of average mains current draw and generated heat, and utilising the PLM+ Series’ innovative power supply technologies in combination with BEL the mains draw can be safeguarded to a predicted level. The end result is precise mains management and thermal control, which allows more accurate provision of mains distribution, cabling and cooling. CAFÉ reduces lifetime running costs and minimises environmental impact, and also reduces demands on UPS systems.

Allocate Power Where It Is Needed
RPM Provides ultimate flexibility of power output allocation across channels to match specific load requirements, enabling more efficient use of amplifier inventory

More is More: Power, Performance, and Processing
PLM+ offers unprecedented levels of refined performance, double the processing power, and even better overall efficiency – proven, tested and trusted.

CAFÉ with ESP: Configuration, Control, and Monitoring
LAB GRUPPEN’s dedicated integrated software provides comprehensive system surveillance, reducing running costs and minimising environmental impact.
