Audio Cable Wiring
All audio and GPIO connections to the BLU-50 are via Klippon pluggable terminal block connectors (also known
as BL, Phoenix or Combicon)� 12-way female Klippon connectors are supplied for making these connections�
Audio Input and Output Wiring Convention
Soundweb products provide cable shielding ‘back from the destination’ to eliminate ground loop problems� This
means that the shield (S) connection on an input is grounded, whereas the shield connection on an output is
floating (although connected via an internal network to ground for EMC compliance).
Balanced Wiring
The convention for balanced wiring (2-core plus shield) is shown here:
