Balanced Audio VK-P6SE Phonostage - Manual (Page 8)

The output of the VK-P6SE phono stage has a mute relay that disables it for
about 45 seconds every time the unit is turned ON.
When the unit is powered up it automatically self-mutes until the proper
operating points of the circuitry are reached. It will then go into normal play
mode.
Configuration Switches
WARNINGS:
Please make sure that the VK-P6SE is turned OFF and your
preamplifier is in MUTE before changing the state of any internal
configuration switches in VK-P6SE.
Hazardous voltages are present on the unit’s printed circuit board.
DO NOT operate the VK-P6SE with its top cover removed.

switches, do the following:
1. Turn the VK-P6SE OFF and disconnect the power cord from the
power line receptacle.
