11.4 LED-METERS 

 
The Oxygen 3 and Oxygen 3 ST mixers are fitted with VU / PEAK LED meters. 
 
VU meters respond to an average signal level, whereas PEAK LED glows when the 0dB threshold is over-
passed (it remains ‘on’ long enough to provide easy recognition). 
The VU meters are factory-calibrated and no further user adjustement is allowed.  
 
A short cable with a 9 pins subD plug on each end (male and female) comes with the console. It is used to 
connect the meterbridge to the mixer. 
 
The RIGHT pair of meters always display the Master signal. 
 
The LEFT pair of meters show any combination of the MASTER output, the EXTERNAL input or PFL 
output is selected on the Monitor module
.  
For example, if Monitor section has MASTER selected, then the meters will display the MASTER signal. Of 
course, meters will also display the PFL signal, if PFL listening is selected (see par. 11.3)
