Individual level 
modification 
The I/O module offers the 
option found in professional 
studio technology, to adjust the 
levels of the individual analogue 
inputs against each other. With 
this function, a quieter CD 
player could have its level 
raised so that no volume 
adjustment is necessary when 
switching between sources. 
If you want to edit this function, 
you must first select the source 
in question through the 
SOURCE menu. 
You can choose from: 
Aux-1, Aux-2, Aux-3, Rec-In 
The SOURCE menu is called 
by pressing the Setup button 
for approx. 2 seconds and then 
pressing the Source softkey. 
The following menu appears in 
the display with the Level 
Adjust display in the middle. 
The standard setting is with the 
bar positioned in the middle. In 
this position, the signal is not 
modified. 
If you want to lower or raise the 
level of this source, press the 
-Level or Level+ softkeys 
accordingly. In this way, the 
level can be modified by ± 10 
dB. 
The change can be heard while 
you are making it as the output 
of this source gets quieter or 
louder. 
If the levels are set correctly, 
there shouldn't be any volume 
difference between the adjusted 
analogue source and the M51 
tuner. 
If this is not the case, carry out 
the adjustment again. Once you 
have achieved the required 
level, you can quit the Level 
function by pressing the Source 
or Amplifier  buttons.
