M2 Line Balanced Level 2 line pre-amplifier Owner's Information Music's Finest Conductor
Introduction to the M2 Line Balanced pre-amplifier Congratulations on your purchase of the Audio Note M2 Line Balanced level 2 pre-amplifier. Audio Note Level System First, a word about how we classify our products at Audio Note. The world renowned Audio Note Ongaku, Kegon and Gaku-on amplifiers incorporate six technological design features which give them unmatched sonic performance and clarity, placing them amongst the best amplifiers in the world.
Unpacking and installation Please ensure care is taken when unpacking the pre-amplifier. We recommend that you store the packing materials in case the unit requires shipping at a later date. Also, check that no transit damage has occurred before installing the pre-amplifier. Select a suitable location for the unit, ensuring that adequate ventilation is provided as the pre-amplifier generates considerable heat during normal operation.
Connections Line input Eachline input is suitable for connecting to any line level music source. Line level sources include CD players, radio tuners, televisions etc.Each line input consists of a pair of RCA connectors.The M2 Line Balanced has 4 line inputs available. Tape loop The tape loop is available for connecting to a cassette desk. The 'tape in' connections should be connected to the cassette deck's 'line out' and the 'tape out' connections should be connected to the cassette desk's 'line in'.
Note interconnects are recommended, as they are manufactured to the same exacting standards as all of our products. Operation Once all the connections are completed and checked, make sure all power amplifiers are off and flip the mains rocker switch located on the back panel of the pre-amplifier to the 'on' position. The M2 Line Balanced is a vacuum tube design and therefore requires about 45 seconds warm-up time. After this the remaining system components may now be turned on.
After-care Cleaning Cleaning the M2 Line Balanced is best done with a soft brush - some photographic stores are able to provide suitable brushes. Alternatively, a soft cotton cloth may be used with a mild propriety cleaner for removing dirt build-up. Strong or alcohol based solvents may damage the finish of this amplifier. Ensure the pre-amplifieris switched off and cold when cleaning. Do not wet the unit.
Technical overview The M2 Line Balanced utilises simple but sonically effective circuitry using vacuum tube technology rather than complex techniques using impure semi-conductor type devices, so common in the audio industry. This kind of circuit architecture is incredibly transparent and revealing. As a natural consequence, part material plays an important role in the final sonic performance, so we use only the best possible components and materials.

Safety Information HEAT: By the nature of vacuum tubes, this product generates high levels of heat. Adequate ventilation must be provided. Do not restrict the airflow through any of the ventilation slots or place the amplifier on any surface that may restrict airflow. CAUTION: The vacuum tubes and other nearby parts operate at extremely high temperatures KEEP OUT OF REACH OF CHILDREN. HUMIDITY: Do not store or operate this unit in areas of high humidity or in close proximity to water.
