Turntable / Tonearm with XLR Jack
Within a record player balanced cables should be used. Coaxial cables should be replaced as far as possible.
XLR to XLR is a standard balanced connection. However, here is something special: As a floating
balanced connection, it does not need any ground connection, just non‐inverting and inverting signals.
As far as a shield is in place, it may be connected to pin 1 of the XLR connection at one end only: The
PHONO MCCI end.
If there is need for a ground connection from tonearm to PHONO MCCI, only connect it to XLR pin 1 of
ONE channel. Thus avoiding hum noise due to ground loops.
No connection of any of the 4 signal wires to pin 1 of XLR is allowed!
