Audio Note M1 Line - Manual (Page 8)

OPERATION
Once all the connections are completed and checked, ensure that the volume control
is at the minimum setting (rotated all the way left).
Ensure that all source components connected to the M1 Line Pre Amplifier 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 M1 Line Pre Amplifier 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 M1 Line Pre Amplifier by using the rocker switch located on the rear
panel, above the mains inlet IEC socket.
The M1 Line Pre Amplifier 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.
Source / Tape
This allows you to switch between the selected source input
and the output of your recording device.
Volume Control
This control adjusts the listening level, or loudness. Set as
desired!
Balance Control
This control adjusts the relative left/right levels. Use this control
if necessary to equalize the loudness from each speaker.
Feedback
Switches
Two feedback switches are located next to the ground terminal
on the rear panel; these are used for matching the output of the
M2 Line to the input of the following power amplifier.
Set the switches to the ‘on’ position if any of the following
apply: -
The volume control is too sensitive, and output is too high.
If the interconnects between the M1 Line and the following
power amplifier are longer than 3 meters.
If the power amplifier has an input impedance of less than
50KOhms.
When in doubt, choose the setting that provides the best sonic
performance.
NOTE: Always turn the power off before adjusting the feedback switches. Ensure
that both feedback switches are in the same position.
