Parameter Definitions: 

 

Every input of the VK-33SE is defined with the following set of parameters. 

 

1.  Input name (Examples include CD1, DVD1, PH-1, VKD5, or any other 

combination of up to four characters including the Latin, Cyrillic and Greek 

alphabet as well as digits) 

2.  Balance adjustment – gain shifted Left or Right. 

3.  Volume offset relative to any other input (to compensate for gross 

differences in various sources levels) 

4.  Phase: Inverting, Non-inverting or Last configuration 

5.  Stereo, Mono or Last configuration 

6.  Maximum allowable volume setting for a particular input.  This is a 

convenient safety feature in some instances. 

7.  Display mode.  This allows the user to switch the volume display to operate 

in any of the three modes: relative Counts, DBU (Decibels referenced to 

Unity gain) or DBM (Decibels referenced to Maximum gain).  

8.  Fixed volume mode: this allows any input to be set with a preferred fixed 

volume setting, and is usable, for example, in Audio/Video installations. 

 

With this flexibility it is possible, for example, to set the CD input to be Stereo 

and Non-Inverting, while the Phono input would be Mono and Inverting.  

 

 

 

 

 

 

PROGRAMMING THE VK-33SE 

 

NOTE:  It is important to note here that all the functions described 

below are accessible either through the front panel controls or via the 

VK-R3 remote control.  Therefore, functions like BALANCE, PHASE, 

MONO, etc. all can be performed by using the Function button on the 

remote control in conjunction with the Volume Up/Down buttons. 

 

BALANCE Adjustment. 

 

Pressing the Function button once will invoke the Balance adjustment mode.  

When in this mode, turn the volume control knob (or press the Volume Up/Down 

buttons on the VK-R3 remote control) to set the balance to the desired position.  

An L or R character will appear indicating that the balance is now shifted in the 

corresponding direction.
