Audio Note M1 RIAA - Manual (Page 8)

Phono input Connect the cables from your tonearm to the ‘Input’ sockets. The
inputs are colour coded; RED is for RIGHT channel connection,
WHITE is for LEFT channel connection. If your Turntable is equipped
with a separate earth wire, connect this to the dedicated grounding /
earth post, located in between the Right input socket and the Output
sockets.
If you wish to use a low output Moving Coil (MC) cartridge,
Audio Note (UK) manufactures a series of Step Up Transformers for
this purpose. For further information, please contact your Audio Note
(UK) Dealer, or alternatively please contact us directly.
Mains The M1 RIAA phono stage uses an IEC 320 mains inlet socket. Use
the supplied mains cable to connect the unit to the local mains supply.
The mains fuse and a spare is located in the inlet socket fuse drawer.
Special Note – Make sure that all connections are tight and clean. For
best results use good quality audio interconnects. Although it is
perfectly acceptable to use cables manufactured by other companies,
for best results and performance, we recommend our own Audio Note
(UK) range of interconnects and loudspeaker cables. For further
information, please consult your nearest Audio Note (UK) dealer, or
alternatively please feel free to contact us directly.
Outputs

consisting of two pairs of colour coded RCA / Single Ended sockets.

connection.
RCA The two pairs of RCA / Single Ended outputs are for connection to a
power amplifier and are identical, making them suitable for bi-amping.
