Audio cable wiring
All audio and GPIO connections to the BLU-101 are via Klippon pluggable terminal
block connectors (also known as BL, Phoenix or Combicon). The BLU-101 includes
3-way female Klippon connectors for individual channels.
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:
Balanced cable

Unbalanced wiring - The convention for unbalanced wiring to the inputs (1-core plus
shield) is shown here:
