  • Building upon Lab.Gruppen's touring amplifier technology
  • The E-Series E 4:2 Amplifier is a two-channel amplifier with professional-quality sound and rock-solid durability
  • Well suited for the installation market including bars & restaurants, retail outlets, performing arts centers, hotels, houses of worship, schools, museums & galleries, theme parks, and convention centers.
  • The E 4:2 utilizes Lab.Gruppen's IntelliDrive Energy Efficient Amplifier (IDEEA) technology, which produces high-power levels with low distortion, while drawing minimal mains current. 
  • The built-in Rail Sensing Limiter (RSL) greatly reduces signal clipping to ensure high-quality audio output at all times. 
  • The 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, making it possible, for example, to drive a small sub on one channel and a number of 70 V ceiling loudspeakers on the second channel.
  • The two-channel amplifier offers 200W per channel or 400W total output. 
  • The front panel offers LED indicators, but lacks controls for security purposes. The rear panel offers potentiometers for level adjustment, as well as a variety of limit and gain switches for each channel. All input and output connectors use detachable screw terminals. 
  • The Lab.Gruppen E 4:2 ships with a power cord and several phoenix connectors for input, output and GPI/GPO power controls.
  • High-Power Density: 2 x 100 W in 1 RU
  • Certified Energy Star compliant
  • IntelliDrive delivers comparable power per channel at 70 V or Low-Z (2, 4, and 8 Ohms)
  • Asymmetric Loading: Allows “mixing and matching” of loads with different impedances to maximize system efficiency and inventory utilization
  • IDEEA output state based on patented Class-D variant
  • Low lifetime operating costs
  • High Efficiency: Low-power consumption and low-heat output
  • Auto-Standby Function: Power consumption < 1 W in standby mode
  • RSL Switch: Smart circuit senses rail voltage and optimizes output for instantaneous load conditions
  • Efficient Cooling: Dual temperature-controlled fans
  • Comprehensive circuit protection and fault indication
  • Tested for key functions
  • Tested to accept and amplify signals and that all the controls and indicators were functional.
