Introduction to the M One pre-amplifier

Congratulations on your purchase of the Audio Note M One level 1 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. All
Audio Note products are, where applicable, judged by this standard. These features are:

• Single ended output stage

• Zero negative feedback

• Directly heated triode output stage

• Pure Class A operation

• Materials and component technology

• Valve rectification

Qualification for level 1 requires the inclusion of at least one of these features.

The M One

The M One is a line stage pre-amplifier with 5 inputs, tape loop and two outputs. Based on the M Zero, it
features a zero feedback 6111WA dual triode output stage but with an improvement in the quality of
components used.

The M One incorporates vacuum tube technology to produce the most accurate sound possible. We
have developed the M One using a "comparison by contrast"* technique of aural evaluation - a system
that is currently unique to Audio Note.

Please read this manual carefully in order to obtain the best possible performance and longevity from
your pre-amplifier.

*An essay dubbed "Audio Hell" which describes this system is available from Audio Note on request.

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. Avoid sitting the M One close to any other
equipment, such as a power amplifier, that may be generating a strong magnetic field, or in close
proximity to active mobile telephones.

The M One is capable of driving long interconnects to power amplifiers and so, if you are using mono
block amplifiers, it may be worthwhile to locate them close to the speakers. This will reduce the speaker
cable lengths and provide sonic improvements.

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 M One has 5
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'. The tape in can be used as an additional line input if required. The RCA
connectors are marked red for the right channel and white for the left channel.

Unbalanced output

There are 2 sets of unbalanced outputs are provided for Bi-amplified systems. Both sets are identical and
may be used for single amplifier operation. The connectors are marked red for the right channel and
white for left channel.

Mains power connection

Use the supplied cable to connect the IEC inlet socket on the pre-amplifier to the mains supply. Ensure
the power is switched off when you do this.

NOTE: It is important that all connections are firm, secure and airtight. any oxidisation of the

interconnects will result in loss of performance. Always use high quality interconnects - Audio
Note interconnects are recommended, as they are manufactured to the same exacting
standards as all of our products.
