1.   24V DC:    

indicates that 24V DC power is applied

 

2.   Channel A Fault:  

indicates a fault, e.g.: thermal overload at channel A 

 

 

 

During normal operation this LED fl ashes shortly after powering up until the protection mode 

 

 

 

is terminated and the speaker output is enabled.

3.   Channel A Clip:  

indicates an excessive input signal and the activation of the built-in limiter to prevent a clipping 

   of 

the 

signal

4.   Channel B Fault: 

as item 2, but for channel B

5.   Channel B Clip: 

as item 3, but for channel B

6.   230V AC:   

indicates that the applied voltage is 230V AC. The device is supplied by this voltage - 

 

 

 

the 24V DC remains unloaded.

7.   Channel A Operating Mode: 

Indicates that channel A is active. This means a signal at input A is present, 

 

 

 

 

     which is amplifi ed. If no signal is detected, the amplifi er switches to a low power  

 

 

 

 

     standby mode - the LED turns off.

8.   Channel A Signal: 

indicates that the signal is > 30dB.

9.   Channel B Operating Mode: 

as item 7, but for channel B

10. Channel B Signal: 

as item 8, but for channel B
