1  STANDBY BUTTON:

 Press this button to switch ON the C 275BEE. 

The Standby LED indicator will turn from amber to blue. Pressing the 
STANDBY button again turns the unit back to standby mode.

IMPORTANT NOTICE

 

The rear panel POWER switch must be in the ON position for the 
STANDBY button to activate.

2  STANDBY LED:

 This indicator will light up amber when the C 275BEE 

is in standby state. When the C 275BEE is at ON state, this indicator will 
illuminate blue.  

In cases of serious abuse of the C 275BEE, such as excessively low 
loudspeaker impedance and short circuit, the C 275BEE will engage its 
Protection circuitry, indicated by the Standby LED turning from blue to 
red and the sound being muted. 

In such a case, turn the C 275BEE OFF by the rear panel POWER switch, 
wait for it to cool down and/or check the speaker connections, making 
sure the overall loudspeaker impedance doesn’t go below 4 ohms or 
8 ohms in Bridge mode. Once the cause for the protection circuitry to 
engage has been removed, switch ON the rear POWER button and the 
Standby Button to resume normal operation.

3  BRIDGE MODE INDICATOR:

  This BRIDGE MODE indicator lights up 

blue when the C 275BEE is switched to Bridge Mode.  Refer also to the 
item below about BRIDGE MODE at the IDENTIFICATION OF CONTROLS 
– REAR PANEL. 

4  SOFT CLIPPING INDICATOR:

  The blue SOFT CLIPPING LED shows 

that the SOFT CLIPPING mode is engaged. Refer also to the item below 
about SOFT CLIPPING at the IDENTIFICATION OF CONTROLS – REAR 
PANEL.
