    Technology It is well known to any audio circuit designer worth their salt that accurate reproduction of music relies entirely on the preservation of the purity of the incoming signal. It is therefore not a difficult step to make to realise that the complexity of the circuitry itself must be kept to a minimum in order to retain the musicality of the original performance. In response to this, all Audio Note pre-amplifiers use a single-ended, zero feedback circuit topology. The single-ended gain stage topology is simply the most linear, demanding pure Class A valve operation and removing the need for a phase splitter, which introduces unnecessary crossover distortion. The Audio Note amplifier range does not make use of any kind of feedback. As a result, they were neither designed for vanishingly small harmonic or low intermodulation distortions, but instead for minimal non-harmonic and time base anomalies. It is these non-harmonic amplitude and time base distortion that have a highly perceptible and adverse affect on the signal waveform. Our amplifiers are designed for maximum linearity without ‘corrective’ measures to keep transient distortions to a minimum rather than introducing the recursive errors inherent in feedback loops. The M1 RIAA features an ECC83 and ECC88 phono stage and an improved version of the zero power supply. Unpacking & Installation Please take care when unpacking the pre-amplifier. We recommend that you store the packing materials in case the unit requires shipping at a later date. Next, select a suitable location for the unit, ensuring that adequate ventilation is provided (the valves generate a fair amount of heat). In the interest of safe, reliable operation, situate the pre-amplifier well away from dampness or direct sunshine. Avoid sitting the M1 RIAA 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. Worthwhile sonic improvements may be obtained by locating the unit on a specifically designed audio component support system; we tend to prefer natural materials such as wood. Connections Please ensure that the M1 RIAA, the power amplifier and any source equipment is switched off before making any connections. 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. Inputs The M1 RIAA has one phono input, which consists of a p .....
