Audio Note M9 Phono - Manual (Page 9)

Umbilicals
Two dedicated cables are supplied for connection of the M9 Phono
main unit to the power supply unit. One cable is used for the Line
stage and one is used for the Phono stage.
The cables are fitted with Military specification circular connectors, and
can only be installed in one direction; the male connector attaches to
the PSU ‘power supply out’ sockets, the female connector attaches to
the M9 Phono main unit ‘power supply input’ sockets.
The connectors are a ‘push and twist’ bayonet design, and once the
connector and socket have been aligned, twist the external ring on the
connector to secure it to the socket.
Both cables are identical in construction, but it is important to make
sure the correct output from the PSU is connected to the correct,
corresponding input on the main unit.
If you are in any way uncertain regarding these connections, please
consult your official Audio Note (UK) agent.
Ground Post Each of the chassis is fitted with a separate Earth connection / ground
post. The post located on the main preamplifier unit is for connection
to source components that also use a separate ground terminal. The
ground post located on the power supply can be used in situations
where the following amplifiers require a separate ground connection to
maintain quiet, hum free operation. Please consult your official Audio
Note (UK) agent for further information on how best to use these in
your system.
