The first time connect the Master 2 MK3:
Connect the signal cables between the preamp and Master
2 MK3, confirm the Master 2 MK3 selectors that on the rear have select
to proper position.
About the gain switch , recommend turn to "L"
(20 dB) when the
speakers has higher than 95dB sensitivity , otherwise turn to
"H" (26 dB) .
Users also can try the AB compare find the best choice
because the preamp and listen room size also effect the loud
level, please shut down the amps before switch the gain .

The rule of power on and off the Master 2 MK3:
Power on the transport, then the DAC and preamp ,
latest turn on the Master 2 MK3.
When power off the system, must turn off the Master 2
MK3,
then power off other units in the system.
Please note:
The stock AC power cables can not show the Master 2 MK3
real performance , they are only for test the Master 2 MK3 if can
work. We recommend customer buy the good quality power cables
for the Master 2 MK3, the power amp even need two strong power
cables .
We have the power cable for customer order

How to connect the preamp only had the RCA output :
The Single ended preamp can not show how good of
the Master 2 MK3, we don't recommend that connected.
But if must connect, can built the RCA to XLR
cable connect the preamp and Master 2 MK3.
