LabGruppen E54 500W E-Series Installation Amplifie

System installers in search of a compact - flexible amplifier with Hi-Z and Lo-Z output capabilities should check out the LabGruppen E 54 - a 1 RU - four-channel 500W amplifier for mixed A/V installation applications The E 54 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 LabGruppen'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 (70/100V) 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 70/100V ceiling loudspeakers on the other channels
