Audio Note AN-S4 - Manual (Page 7)

Position the AN-S4 in a suitable location; close your turntable and phonostage input.
It is important to remember that the Step Up Transformers inside the AN-S4 are
highly susceptible to noise created by power supplies, mains cables etc. If you
experience any ‘hum’ problems, move the AN-S4 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-S4 between your turntable and phonostage input.
Connect your tonearm / turntable output cables to the
input sockets on the AN-S4,
and the output sockets of the AN-S4 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-S4. 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, you are now ready to enjoy some music!
