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.
M5 LINE PRE AMPLIFIER Congratulations on your purchase of the Audio Note (UK) M5 Line Pre Amplifier. It has been specifically engineered for sonic performance rather than technical specification, and fulfills all Audio Note (UK) Level 3 criteria: Pure Class A operation Zero negative feedback Single Ended circuit topology Valve rectification Materials and component quality It is well known that the accurate reproduction of music, not just sound, requires the purity of the incoming signal to be preserved.
UNPACKING AND INSTALLATION Please take care when unpacking your M5 Line Pre Amplifier. Choose a clean, clear location to unpack your unit. Be aware that the Pre Amplifier is very heavy; before attempting to unpack or lift the unit, check the weight and if necessary use more than one person so that it can be moved safely and easily. We recommend that you retain and carefully store all of the original packing materials, in case transportation / shipping is required at a later date.
CONNECTION Line inputs Four RCA / Single Ended line inputs are available for connection, labeled ‘Tuner’ ‘Aux’ ‘CD1’ and ‘CD2’; any standard ‘line level’ source can be connected to these inputs. All sockets are colour coded; RED is for RIGHT channel connection, WHITE is for LEFT channel connection. Mains The M5 Line Pre Amplifier uses an IEC 320 mains inlet socket. Use the supplied mains cable to connect the unit to the local mains supply.
CONNECTION continued… Balanced The M5 Line is equipped with custom designed and manufactured output transformers, which utilize an improved output and grounding scheme to provide the best possible connection to the power amplifier.

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 M5 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 M5 Pre Amplifier are switched OFF.
OPERATION continued… Bedding in The new amplifier requires about 200 hours of initial use (called “bedding in”) before the circuitry becomes stable and optimum performance is realized. As the amplifier “beds in” the sound will become increasingly smoother, detailed and open. Once the amplifier has “bedded in” a warm up time of approximately 30 to 45 minutes is required each time the amplifier is switched on before optimum sonic performance is reached.
