INTRODUCTION Thank you for purchasing this Audio Note (UK) product. With the correct care it should give you many years of pleasure and enjoyment. Please take the time to read all of the information in this manual before connecting your new component to an electrical supply or your system, to ensure both your safety and satisfaction. Please note that due to our desire to continually improve products, specifications are subject to change without notice.
M9 PHONO PRE AMPLIFIER Congratulations on your purchase of the Audio Note (UK) M9 Phono Pre Amplifier. It is without doubt or question, the finest Phonostage equipped preamplifier we have ever produced, and the Line Stage is only surpassed in performance by our own M10 Line. As one would expect, no expense has been spared in the construction of the circuit or the components used, and is a full Audio Note (UK) Level 5 product.
UNPACKING AND INSTALLATION Please take care when unpacking your M9 Phono preamplifier. Choose a clean, clear location to unpack your units. Be aware that the preamplifier and its power supplies are extremely heavy; before attempting to unpack or lift the units, check the weight and if necessary use more than one person so that they can be moved safely and easily.
CONNECTION OVERVIEW Phono Inputs The M9 Phono is equipped with an extremely high quality, valve, Moving Magnet (MM) phonostage. Connect the cables from your tonearm to the ‘Phono’ socket inputs. If your Turn Table is equipped with a separate earth wire, connect this to the dedicated grounding / earth post, located next to the ‘Phono’ input sockets. If you wish to use a low output Moving Coil (MC) cartridge, Audio Note (UK) manufactures a series of Step Up Transformers for this purpose.
CONNECTION OVERVIEW continued… Umbilicals Two dedicated cables are supplied for connection of the M9 Phono main unit to the power supply unit. One cable is used for the Line stage and one is used for the Phono stage. The cables are fitted with Military specification circular connectors, and can only be installed in one direction; the male connector attaches to the PSU ‘power supply out’ sockets, the female connector attaches to the M9 Phono main unit ‘power supply input’ sockets.

CONNECTION OVERVIEW continued… Mains The M9 Phono preamplifier power supply is equipped with 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 the circular receptacles beneath the mains inlet.
CONNECTION OVERVIEW continued… Outputs The M9 Phono preamplifier provides two Single Ended / RCA 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 pair of balanced outputs, consisting of a pair of ‘male’ XLR sockets (see ‘Balanced’ section, below).
CONNECTION OVERVIEW continued… RCA The two pairs of RCA / Single Ended outputs are provided for connection to power amplifiers. They are identical, making them suitable for bi-amping. RCA SOCKET, SHELL = NEGATIVE / RETURN. RCA SOCKET, CENTRE = POSITIVE / SEND. Balanced The M9 Phono preamplifier is equipped with custom designed and manufactured output transformers, which feature an improved output and grounding scheme to provide the best possible connection to the power amplifier.
CONNECTION OVERVIEW continued… The pin configuration for all Audio Note (UK) XLR / BALANCED connections is as follows: PIN 1 PIN 2 PIN 3 Ground / Shield Positive / Send Negative / Return The balanced and single ended outputs cannot be used simultaneously; select the appropriate output using the toggle switch. When using an amplifier with a true balanced input, the ‘BALANCED / SINGLE ENDED’ switch may be set in either position.

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.
OPERATION continued… Bedding in The new preamplifier requires around 200 hours of initial use (called “bedding in”) before the circuitry becomes stable and optimum performance is realized. As the preamplifier “beds in” the sound will become increasingly smoother, detailed and more open. Once the amplifier has “bedded in” a warm up time of approximately 20 to 30 minutes is required each time the amplifier is switched on before optimum sonic performance is reached.
