7.4. LED indicators 

 

SP

: The signal presence or 

SP

 LED indicator shows that there is a signal in the 

amplifier input. This light up when the input level reaches the established detection 
threshold. 

 

CLIP

: The saturation or 

CLlP

 LED indicator comes on when the signal delivered to 

the speakers is close to the amplifier's clipping or saturation level. Input signals 
should be set to ensure the 

CLIP

 (saturation or cut off) indicators never stay on, but 

that they do so at most to the beat of the lowest sound frequencies. Otherwise the 
amplified signal will be distorted with low quality and low intelligibility. 

Note:

 If the input signal is too high, the CLIP indicator lighting up very frequently 

over a short time  interval (a few seconds), the amplifier may go into protection 
mode, being muted to return to normal operation in a short time 

 

MUTE

: This light up when the 

MUTE

 function is active (silent mode) 

 

ON/STBY

: the green light comes on when the equipment is in normal operating 

mode  and  it  goes  orange  when  it  is  in  standby  or  low  consumption  mode 
(STANDBY). 

 

LEVEL: 

This flashes when you adjust the general level of the device. It also lights 

up during special adjustment modes, input levels (

see section 7.2. Special active 

source selection mode and setting adjustments

) 

 

BASS: 

This light up during special adjustment modes bass frequencies (

see section 

7.2. Special active source selection mode and setting adjustments

) 

 

TREBLE

: This light up during special adjustment modes, treble frequencies (

see 

section 7.2. Special active source selection mode and setting adjustments

) 

 

LINE1, LINE2, LINE3/MIC

: These light up during special modes, selection of active 

sources and adjustments (

see section 7.2. Special active source selection mode and 

setting adjustments

)
