3.4. Switching on for the first time – the Soft-Start feature
The RE 290 is equipped with a multi-stage Soft-Start-Turn-On protection circuit which extends
component as well as tube life considerably by protecting against stress caused by typical high
inrush currents during switch on.
1) Check that the Ecomode switch on the rear panel is in the "Eco off" position
2) Connect the RE 290 to the mains. (On new units, this switch is set to "off" at the factory).
3) Switch on the RE 290 using the amplifier’s mains power on/off switch.
The Power-LED next to the mains switch will illuminate.
