Audio Note AN-S9

Audio Note AN-S9

The Audio Note AN-S9 is a passive device, designed to convert the mainly current output of your Moving Coil cartridge (MC) to a higher voltage, low current signal of sufficient strength to allow a Moving Magnet (MM) phono stage to amplify it to a suitable level.

Custom Silver Transformers

The internal transformers used in the AN-S9 are manufactured by Audio Note (UK) exclusively. They are the finest possible transformers available today, producing a level of information retrieval that is unsurpassed by any other such devices. They use our own interleaved super mumetal 250 cores, 99.99% pure Silver wire and are housed in large mumetal screening canisters to minimise noise and interference. The transformer cans are then secured inside the chassis with a solid copper clamp, offering the best possible support for these delicate devices.

Low, Medium and High versions

The AN-S9 can be supplied in the following standard versions to suit the internal impedance of your cartridge: –

AN-S9/L  – 3 Ohm input impedance – Primarily designed for use with the Audio Note (UK) IO range

AN-S9/M – 12 Ohm input impedance – For cartridges with an internal impedance of 3 to 4 ohms

AN-S9/H – 60 Ohm input impedance – For cartridges with an impedance of 15 to 20 Ohms

Internal Impedance

It is possible to use our transformers with cartridges that have greater internal impedance, or values that are outside the preferred ranges of the standard inputs, however, it is important to realise that an input impedance in the region of three to four times the internal impedance of your cartridge will usually provide the best results.

If your chosen cartridge has an internal impedance that does not reasonably accurately match one of the standard input impedance values, please consult your Audio Note (UK) Dealer for further advice.

Output cables

Rather than installing the usual output RCA connectors, we decided to hard wire a pair of our PALLAS low capacitance cables directly to the outputs of the transformers. However, if you would prefer standard RCA sockets, we can provide these as an option. We can also install any other Audio Note (UK) interconnect cable of your choice. Please consult your authorised Audio Note (UK) Dealer for further information.
