The output of the VK-P6 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-P6 is turned OFF and your
preamplifier is in MUTE before changing the state of any internal
configuration switches in VK-P6.
Hazardous voltages are present on the unit’s printed circuit board.
DO NOT operate the VK-P6 with its top cover removed.
This section describes the setting of internal configuration switches that are
located inside the VK-P6 phono preamplifier. In order to access these
switches, do the following:
1. Turn the VK-P6 OFF and disconnect the power cord from the power
line receptacle.
2. Remove the top cover, using the supplied Torx T-10 wrench.
Figure 1 depicts the locations of the VK-P6 internal configuration switches.
