The coaxial connection is a questionable compromise which might be useful for testing. An already
present RCA connection can just be connected to XLR plugs. This is not a balanced connection indeed
and this you may expect some noise interference. Concering sound quality we do not recommend this
solution either.
The best way to connect is a balanced "twisted pair" cable with additional shielding. The cartridge can
be dirctly connected to the balanced input this way and the shield is connected just one‐sided and
eventually to the turntable chassis. No cardridge pin is allowed to be shorted to the tonearm or chassis!
With this connection you can enjoy exellent sound quality results.
A balanced connection without any shielding might sound best as long as you don't experience any
noise by interferences. Twisted cables are mandatory for this type of connection! The CI‐input is not
very sensitive to capacitive noise and also has a high rejection of common‐mode noise. The cable
should generally be low‐inductive for CI‐connections. In case of any trouble you better use the above
suggestion.
In case of making a testing adaptor from RCA to XLR following point
should be considered:
1. The adaptor must be connected according to the above drawing. Pin
1 of the XLR Plug must remain unnused!
2. None of the RCA grounds is allowed to be connected to the tonearm or chassis.
Better check the above suggestion by a multi‐meter for short circuits.
As this is indeed not a clean balanced interconnection you may expect some noise as well as reduced
sound quality. Such adaptor should be just a short‐term solution.
Any unbalanced cable at the Phono MCCI input is a waste of sound quality!
NEVER plug any cable while the unit is powered on!
