INTRODUCTION

The AN-S2 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-S2 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-S2 can be supplied in two versions; the AN-S2/L (low impedance) and the
AN-S2/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.

Position the AN-S2 in a suitable location, close your turntable and phonostage input.
It is important to remember that the Step Up Transformers inside the AN-S2 are
highly susceptible to noise created by power supplies, mains cables etc. If you
experience any ‘hum’ problems, move the AN-S2 to a different location, further away
from possible causes of noise, and try changing it’s orientation, rotating it clockwise /
anticlockwise until any noise is eliminated / reduced to an acceptable level.
Once located, connect the AN-S2 between your turntable and phonostage input.
Connect your tonearm / turntable output cables to the input sockets on the AN-S2,
and the output sockets of the AN-S2 to your MM phonostage input. It is important to
use good quality, shielded interconnects for all turntable connections; this will help to
minimize any noise or hum problems.
If your tonearm has a separate earth lead, connect this to the dedicated earth /
grounding post located on the rear of the AN-S2. It may also be worthwhile
connecting this earth / ground post to the earth / ground post of your pre-amplifier /
phonostage / amplifier (if one is available). This will often further reduce low level
noise or ‘hum’, however this is not always guaranteed, so some experimentation is
advised to ascertain the best arrangement.
Once all connections have been made, adjust the impedance switches on the rear of
the AN-S2 to the appropriate setting for your cartridge. You are now ready to enjoy
some music!
