OPERATIONAL CONSIDERATIONS

 

 

5.1 

Mains O n- Off Switching and level 

On-Off switching is provided by a rocker switch on the rear panel. Intelligent circuitry ensures  
noiseless power-on and power off. 

5.2

 

 

Thermal 

The output devices of the internal power amplifiers are mounted onto an internal heatsink,  
which heats up and reaches temperatures well above that of ambient. The design is such that  
no forced cooling is necessary, provided sufficient free space can be maintained around the  
cabinet to allow the air to circulate freely. The internal circuitry monitors temperature to  
maintain its safe operating area. Should this detect unsafe temperatures, output is muted to 
protect the amplifier. You will need to turn the unit off and on to reset the protection. This 
will  
only work if the amplifiers temperature has fallen within its safe working threshold.  

5.3 

Front Panel Indicators

 

A multi function LED is mounted behind the LOGO badge on the front of the cabinet. On 
initial turn on the LED will flash green this indicates that the amplifier is warming up (see
