  • Flexible IntelliDrive delivers similar power per channel at 70V, 2, 4, 8 and 16 ohms
  • Asymmetric loading allows mixing and matching of loads with different impedances to maximize both overall system efficiency and inventory utilization
  • Patented IDEEA output stage based on Class-D topology
  • High efficiency Extremely low power consumption and heat output
  • Exceptionally low cost of ownership over lifetime
  • RSL switch circuit senses rail voltage and optimizes output for instantaneous load conditions
  • Efficient cooling One temperature-controlled fan
  • Comprehensive circuit protection and fault indication



The combination of a high-headroom power supply and the dual range RSL enables asymmetric loading on E Series amplifiers. What does that mean for you? In many Kingdom Halls, this means the main auditorium can use more power to run the auditorium speakers while the auxiliary areas share what is left. Gone are the days of having to dedicate a 200W channel solely to a 10W load.
