VK-40 PROGRAMABLE FUNCTIONS 

 
The VK-40 programming functions allow the user to optimize the unit configuration for any 
particular system set up.  The flexible programming facility defines each signal input with a group 
of user-selectable parameters that are then stored in the unit’s memory.  Every time a particular 
input is selected, its unique combination of parameters is loaded into the operating memory.  
Programming is easy and is accomplished through using just two front panel controls -: the 
Function button and Volume knob, or corresponding remote control buttons (Function and 
Volume Up/Down buttons). 
 
Every unit comes from the factory with a default set of parameters stored in its memory.  This set of 
parameters is usable for many applications.  The default set includes the following parameters: 
 

BALANCE     

 

 

ZERO 

 
RELATIVE VOLUME  

 

ZERO 

 

 

PHASE 

 

 

 

Non-Inverting 

 
MONO/STEREO 

 

 

STEREO 

 
MAXIMUM VOLUME 

 

140 

 
FIXED GAIN   

 

 

OFF 

 
DISPLAY  

 

 

 

COUNTS 

 
INPUT NAMES  

 

 

TAPE 

TUN 

CD1 

AUX1 

AUX2 or PH1 if the phono card is installed 

 
 
The user may at any time, configure the unit to a particular set of system requirements.  For 
example, input names can be changed to reflect a given system’s source configuration.
