Audio Note AN-S4

​Custom Silver Transformers

​The internal transformers used in the AN-S4 are manufactured by Audio Note (UK) exclusively. Each transformer is made from 0.1mm laminated super mumetal 250 and wound with 99.99% pure Silver wire. Each Transformer is then housed in a mumetal screening canister to minimize noise and interference.

​Low, Medium and High Versions

​The AN-S4 can be supplied in the following standard versions to suit the internal impedance of your cartridge: -

​AN-S4/L  - 3 Ohm input impedance - Primarily designed for use with the Audio Note (UK) IO range

AN-S4/LM - 4 Ohm input impedance - For cartridges with an impedance of 1 to 2 Ohms

AN-S4/M - 16 Ohm input impedance - For cartridges with an impedance of 4 to 6 Ohms

AN-S4/H - 64 Ohm input impedance - For cartridges with an impedance of 16 to 21 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.
