Audio Note M3 Line - Manual (Page 8)

Line inputs Four RCA / Single Ended line inputs are available for connection,
labeled ʻTunerʼ ʻAuxʼ ʻCD1ʼ and ʻCD2ʼ; any standard ʻline levelʼ source
can be connected to these inputs.
All sockets are colour coded;
RED is for RIGHT channel connection,
WHITE is for LEFT channel connection.
Mains The M3 Line Pre Amplifier utilizes an IEC 320 mains inlet socket. Use
the supplied mains cable to connect the unit to the local mains supply.
The mains fuses are located in separate fuse holders, located on the
rear panel.
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.
Ground Post A ground post is provided for connection to those source components
that also use a separate ground terminal.
Outputs
The M3 Line provides two unbalanced outputs, consisting of two pairs
of colour coded RCA / Single Ended sockets.
RED is for RIGHT
channel connection, WHITE is for LEFT channel connection.
There is also a balanced output, consisting of a pair of ʻmaleʼ XLR
sockets (see ʻBalancedʼ section, below).
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.
