Wireless Microphone Systems
We do our best to keep healthy stocks across the many Wireless Microphone System SKUs but in the rare case where we don't have your required system in stock, please contact our sales team as we can often make your product to order by borrowing the system components (transmitters, receivers or mics) from other stocked systems.

Main Features
2,000 W amplifier carrying 4 flexible output channels in a high power density 1 rack unit
Delivering 4 x 500 W on any channel for all loads (2, 4, 8 or 16 Ohms or Hi-Z 70 V or 100 V)
Energy efficient
High efficiency amplifier with low power consumption
E 20:4 Energy Efficient Class-D Amplifier 4x500W 19" 1U
The E 20:4 has smart green credentials delivering low lifetime cost of ownership.
Building on Lab Gruppen’s touring reputation for sonic excellence and rock-solid durability, E Series brings a competitive edge to the installation market by adding ultra-compact size, high operating efficiency, output configuration flexibility, and an unprecedented cost-benefit ratio.
At the heart of E Series is Lab Gruppen’s IDEEA (IntelliDrive Energy Efficient Amplifier) technology. Based around a patented Class D variant output stage, IDEEA produces high power levels with very low distortion while drawing minimal mains current.
Lab Gruppen’s proprietary Rail Sensing Limiter (RSL™), also exclusive to E Series, greatly reduces signal clipping to ensure high quality audio output at all times. User configurable for Hi-Z (70 V or 100 V) or Lo-Z, RSL senses rail voltages and optimizes each output for instantaneous load conditions. RSL settings also facilitate asymmetric loading of the channels to optimize performance and efficiency. Total available output power can be allocated among the channels as required by the application. This makes it possible, for example, to drive a small sub on one channel, a number of 70 V ceiling loudspeakers on the second channel.
Product Features
2,000 W amplifier carrying 4 flexible output channels in a high power density 1 rack unit form factor saves rack space and system cost
Energy efficient for supreme green credentials and exceptionally low lifetime running costs
Flexible IntelliDrive permits delivering the 4 x 500 W on any channel for all loads (low impedance 2, 4, 8 or 16 Ohms or Hi-Z 70 V or 100 V)
Asymmetric channel loading allows mixing and matching loads with different impedances to maximize overall system efficiency and inventory utilization
High efficiency amplifier with low power consumption and minimized heat generation lowers demands on the installations' mains distribution and cooling systems
