Lab.Gruppen

System installers in search of a compact, flexible amplifier with Hi-Z and Lo-Z output capabilities should check out the Lab.Gruppen E 4:2, a 1 RU, two-channel 400W amplifier for mixed A/V installation applications. The E 4:2 utilizes IntelliDrive Energy Efficient Amplifier (IDEEA) technology to produce high power levels with very low distortion while drawing minimal mains current. E-Series amplifiers also utilizes Lab.Gruppen's proprietary Rail Sensing Limiter (RSL) technology, which greatly reduces signal clipping to ensure high-quality audio output all the time. The amplifier is user-configurable for Hi-Z (70V) or Lo-Z. The RSL circuit senses rail voltage and optimizes each channel output for instantaneous load conditions. This allows for asymmetrical channel loading for optimized 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 and several 70V ceiling loudspeakers on the second channel.Benefits 400W amplifier carrying 2 flexible output channels in a high power density 1 rack unit form factor saves rack space and system costEnergy efficient with Energy Star certification for supreme green credentials and exceptionally low lifetime running costsFlexible IntelliDrive permits delivering the 2 x 200W at constant voltage 70V or low impedance (2, 4, and 8 ohms) on any channelAsymmetric channel loading allows mixing and matching loads with different impedances to maximize overall system efficiency and inventory utilizationHigh-efficiency amplifier with low power consumption and minimized heat generation lowers demands on the installations' mains distribution and cooling systemsIDEEA outputs stage based on proprietary, state-of-the-art Class-D amplifier technology for superior performanceComprehensive fail-safe circuit protection ensures continued operation even under reduced operating conditionsAuto-standby and auto-power-on reduces power consumption to below 1W in non-operating cyclesRail Sense Limiter (RSL) greatly reduces signal clipping and ensures simple configuration for constant voltage and low-impedance loadsBuilt-in 50 Hz high-pass filter selectable per channel available on rear-panel switchPer-channel attenuation knob and signal LED on rear panel for simple commissioningEfficient cooling with temperature-controlled fan with front-to-back airflowAluminum front panel with power and temperature LEDs and per-channel signal and limit LEDsGPIO connector with power control and indication for further system integrationBalanced high-quality analog inputs and amplifier outputs on detachable screw terminals
