8. USING THE (SUPER) BLACK BOX
8.2. Super Black Box option
Operation
Blue power LED
The blue "power" LED illuminates when the power amplifier is switched on via the
amplifier's power on/off switch.
Yellow unload LED
The yellow "unload" LED (discharge control circuit) lights up for approximately two
seconds after switch-off, in case the electronic protection is activated and if the RE 290 is
powered down through the Ecomode. The Super Black Box is equipped with a rapid
discharge circuit, which discharges the unit's electrolytics. The yellow LED indicates that
that this procedure is taking place. The discharge circuit also activates if the SBB
connecting cable is accidentally removed. This is to prevent the SBB maintaining its
charge when it has not been properly disconnected.
