RELATIVE Volume adjustment

 
It is quite common to have sources with very different output levels connected to a preamplifier.  In 
this case, switching between different inputs is usually accomplished by a large change in volume.  
The VK-40 allows the user to avoid this inconvenience by setting volume offsets between different 
inputs (using ANY input as a reference).   
 
To program this feature: 

 

1.  Select any input that you would like to use as a reference.  Play music at the level you find 

comfortable. 

2.  Press the Function button twice.  The display will read:  VOL    000 
3.  Switch to a different input.  Adjust the volume while playing the music to the level that is 

comparable to the reference input level.  The display will indicate the volume offset 
number.  That number can be either positive or negative, depending upon whether the new 
selected input is stronger or weaker than the reference input. 

4.  Exit the programming mode by pressing and holding the Function button or by switching 

to a different input. 

 
Any input volume offset can be programmed at ANY time with respect to ANY other input.   
 
 

EXAMPLE: 

 

The CD1 input is used as the reference.  Let’s presume that the PH1 input (the weaker source) is 
then programmed to play at 20 counts higher.  Its volume offset will then read 20.   
 
The user can later select the PH1 input and using it as the reference, program the AUX1 input to be 
10 counts lower than the PH1 input.  Effectively, the volume offset from the CD1 input to the 
AUX1 will now become 10. 
 
The user then can at any time verify his volume offset programming by switching the unit in its 
VOLUME mode (by pressing the Function button twice) and then selecting the inputs 3, 4 and 5.  
The volume offset numbers for these inputs should then read 0, 10 and 20 respectfully.  That means 
that the AUX1 source will be played at 10 counts above the CD1 input and the PH1 input at 20 
counts above the CD1 input. 
 

 
 
Alternatively, the volume offset number can be entered directly, based on your judgement of 
volume difference between the two sources.  To do that, select the input, enter the VOLUME 
programming mode by pressing the Function button twice, and use the volume knob to set the 
volume offset number that you deem desirable.  Then exit the programming mode by pressing and 
holding the Function Button

 
NOTE:  A negative number for the selected input indicates that its gain will be set lower than 
the gain of the reference input.
