Blue power LED 

 

The blue "power" LED illuminates when the power amplifier (or 
integrated amplifier) is switched on via the amplifier's power 
on/off switch. 

 Yellow 

unload 

LED 

 

The yellow "unload" LED (discharge control circuit) illuminates 
for approximately two seconds after switch-off, and also when 
the electronic protection is activated and when the V 40 SE is 
powered down with Ecomode on. 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.  

 

 

Connecting to the amplifier 

 

 

Warning! Before connecting the Super Black Box, make sure 
that the power amplifier is switched off via its on/off switch or 
disconnect the plug from the wall outlet. 

 

When inserting the connector, guide the anti-rotation lug 
carefully into the mating recess in the socket.  

 

N.B. The LED on the Super Black Box extinguishes when the 
amplifier's electronic protection circuitry is activated, as the 
protection circuitry shuts off the power to the amplifier.
