Pin 3: negative For the VK-33SE, use the Main 1 XLR Output for connection to your balanced power amplifier. The Output 2 is configured as an RCA connector output. Single-Ended Components Single-ended components have RCA connectors. The VK-33SE preamplifier is designed to work with mix of single-ended and balanced components connected to its inputs and outputs. -

Balance mode. More on that in the corresponding sections of this manual. The volume control knob on the VK-33SE is linked to a digital encoder and is of a continuously rotating type (there are no stops). -
Page 12: Display Brightness Function
The VK-33SE has two mute modes: manual and automatic. The blue LED above the Mute button goes ON when the unit is in MUTE state. To MUTE the VK-33SE, depress the MUTE button located on the right side of the front panel. Depressing this button again will return the unit to its normal operation and turn the mute LED off. -
Page 13: Vk-33Se Programmable Functions
VK-33SE PROGRAMABLE FUNCTIONS The VK-33SE 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. -
Page 14: Parameter Definitions
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. - Page 15 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-33SE allows the user to avoid this inconvenience by setting volume offsets between different inputs (using ANY input as a reference).
-
Page 16: Mono/Stereo
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. -
Page 17: Fixed Gain
Most often it is required to set the preamplifier gain to Unity (Gain of 1). The VK-33SE allows the user to do so by using its FIXED gain function. Press the Function button six times. -
Page 18: Display Mode
DISPLAY MODE programming The volume display of the VK-33SE can be switched to work in any of the following three modes: CNTS: Relative volume counts with the range of 000 to 140 DBU: Decibel readings with respect to unity gain (0dB). -
Page 19: Remote Control Functions
Advance to the next character by pressing the Function button once. Exit the programming mode by pressing and holding the Function button . REMOTE CONTROL FUNCTIONS: The optional VK-R3 remote control that comes with your VK-33SE has the following functions: Volume Up and Volume Down control Mute function... -
Page 20: Mute
Mute Pressing this button will cause the MUTE function in the VK-33SE to toggle between ON and OFF states. The Mute LED on the VK-33SE front panel will reflect the status of the Mute circuit. Fade Pressing the FADE button on the VK-R3 remote control will cause the volume to smoothly decay over the period of several seconds. -
Page 21: Fuse Protection
Fuse Protection: A blown fuse in the VK-33SE is an indication of a serious problem. If a replacement fuse fails as well, no further attempts should be undertaken. Please contact the factory for professional service. The proper fuse ratings are as follows:... -
Page 22: Resetting The Vk-33Se
RESETTING THE VK-33SE: Under certain conditions it might become desirable to reset the internal microprocessor that controls all the functions of the VK-33SE. Doing so will erase ALL user programmed setpoints, and will return the unit to its factory default state. -
