KEY 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

  • IDEEA outputs stage based on proprietary, state-of-the-art Class-D amplifier technology for superior performance

  • Comprehensive fail safe circuit protection ensures continued operation even under reduced operating conditions

  • Auto-standby and auto-power-on reduces power consumption in non-operating cycles

  • Rail Sense Limiter (RSL) greatly reduces signal clipping and ensures simple configuration for constant voltage and low impedance loads

  • Built in 50 Hz high pass filter selectable per channel available on rear panel switch

  • Per-channel attenuation knob and signal LED on rear panel for simple commissioning

  • Efficient cooling with temperature-controlled fan with front to back airflow

  • Aluminum front panel with power and temperature LEDs and per-channel signal and limit LEDs

  • GPIO connector with power control and indication for further system integration

  • Balanced high-quality analog inputs and amplifier outputs on detachable screw terminals

 

DESCRIPTION

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.

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. This enables you to drive a small sub on one channel and a number of 70 V distributed ceiling loudspeakers on the other.

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.
