Audio Note M9 Phono - Manual (Page 16)

OPERATION
Once all the connections are completed and checked, ensure that the volume
controls are at the minimum setting (rotated all the way left).
Ensure that all source components connected to the M9 Phono preamplifier
are switched ON. Source components should always be the FIRST components to
be switched on and the LAST components to be switched off.
Ensure that all power amplifiers connected to the M9 Phono preamplifier are
switched OFF. Any power amplifiers in use should be the LAST components to be
switched on, and the FIRST components to be switched off.
The above procedure minimizes the possibility of loud noises produced by
components at switch on being passed to the loudspeakers and possibly causing
damage.
Turn on the M9 Phono preamplifier by using the rocker switch located on the rear
panel of the power supply unit above the mains inlet IEC socket.
The M9 Phono preamplifier requires approximately 45 seconds to initialize before it is
ready for operation.
Input Selector
Turn the selector to the source you wish to listen to.
Volume Control
This control adjusts the listening level, or loudness. Set as
desired!
Stereo / Mono
A Stereo / Mono selector is provided so that mono recordings
can be correctly replayed through the M9 Phono.
