PSU CONNECTOR:
To use the Thesis , connect the PSU cable supplied with the .
To use the internal PSU of the , a separate special
cable is needed (not supplied, available on
request).
GND:
Two different earthing points are available. The chassis ground,
or the signal ground can be choosen, whichever
gives the best noise results in the actual system.
CONNECTIONS:
It is best to do any cable connection when the amplifiers are
switched off.
PLACEMENT:
For best noise results, place your turntable and the Thesis far
from devices with larger transformers or other
devices that may cause electromagnetic
interference (power amps, wifi routers, etc.)
