Do not stack the VK-P5 phono stage on top of other units, nor vice versa. General Description of VK-P5 Phono Preamplifier The VK-P5 balanced all-tube phono stage is designed to provide the maximum possible performance while operating in conjunction with the wide verity of phono cartridges available today.
Output Connection The VK-P5 is equipped with XLR output connectors. Any high quality set of balanced interconnects can be used to connect the VK-P5 to your balanced preamplifier. Single-ended preamplifiers can be connected to the VK-P5 output through the use of XLR- to-RCA adapters, available from BAT.
Configuration Switches WARNINGS: Please make sure that the VK-P5 is turned OFF and your preamplifier is in MUTE before changing the state of any internal configuration switches in VK-P5. Hazardous voltages are present on the unit’s printed circuit board. DO NOT operate the VK-P5 with its top cover removed.

Cartridge loading switches S101 and S201 Resistance: The 47K load resistor is permanently connected to the cartridge input. If a different loading value is desired, it can be obtained by switching in additional resistors, installed on the VK-P5 PC board. This is accomplished by using the two DIP switches, S101 and S201, which allow multiple choices for resistive and capacitive cartridge loading.
Gain Switch By moving the switch S2 from High to Low position, the amplifier’s gain is reduced by about 6dB. While the High gain position provides the most universal setting, it may be desired to reduce the overall system gain when using some high output phono cartridges. Gain Potentiometers Gain potentiometers R130 and R230 allow the user to optimize the VK-P5 performance when using very high output cartridges.
Factory supplied fuses should be only replaced with the same type and rating parts. Servicing The Balanced Audio Technology VK-P5 should require no service other than changing tubes to maintain its high performance. The vacuum tubes used in the VK-P5 are high quality 6922’s and 6SN7’s rated for approximately 5000 hours of use.
