Page 10: Vk-52Se Programmable Functions
VK-52SE PROGRAMING FUNCTIONS The VK-52SE 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. -

Parameter Definitions: Every input of the VK-52SE 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. -
Page 12: Volume Offsets
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.

Page 13: Phase
PHASE programming. Select the desired input. Press the Function button three times. The display will read: PHASE NINV. Use the volume knob to set the condition to NINV, INV or LAST. Exit the programming mode by pressing and holding the Function button. NOTE: In the LAST mode, the state of the PHASE switch will be the same as used the last time for that particular input. -
Page 14: Fixed Gain
FIXED Gain mode In some systems (some A/V installations, for example) it is desirable to set a particular input to a fixed gain, that is then becomes unaffected by the volume knob. Most often it is required to set the preamplifier gain to Unity (Gain of 1). -
