The E1300 features a high-frequency switching power supply,
with on-board intelligent control providing very high
performance in a lightweight 9.5kg, 2U package. This amplifier
also has a plug-in module facility located behind an easily
removable front panel section, which obviates the need for costly
stand-alone dedicated controllers in many applications.
