User Manual

The AN-S1 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) phonostage to amplify it to a suitable level.
The internal transformers used in the AN-S1 are manufactured by Audio Note (UK)
exclusively, use the very best core materials and winding technology available at the
price, and are housed in mumetal screening canisters to minimize noise and
interference.
The AN-S1 can be supplied in two versions; the AN-S1/L (low impedance) and the
AN-S1/H (high impedance).
The ‘L’ version has a switchable input impedance of 3 Ohms and 12 Ohms; the ‘H’
version, 15 Ohms and 60 Ohms.
The 3 Ohm input of the ‘L’ version has been primarily designed to partner the Audio
Note IO Moving Coil cartridges, and the 12 Ohm input is intended to be used with
cartridges with an internal impedance of around 3 to 4 Ohms.
The 15 Ohm input of the ‘H’ version is designed to partner cartridges with an internal
impedance of around 4 to 5 Ohms; the 60 Ohm input is designed for cartridges with
internal impedances in the region of 15 to 20 Ohms.
It is possible to use our transformers with cartridges that have greater internal
impedances, or values that are outside the preferred ranges of the switchable inputs,
however, it is important to realize that an input impedance in the region of three to
four times the internal impedance of your cartridge will usually provide the best
results.
