Audio cable wiring
All audio and control connections to the BLU-80/BLU-32/BLU-16 are via Klippon
pluggable terminal block connectors (also known as BL, Phoenix or Combicon). 6-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:
Balanced connection BLU-80 connection
Pin 3: Cold ‘-’
Pin 2 : Hot ‘+’
Pin 1 : Shield
Unbalanced wiring - The convention for unbalanced wiring to the inputs (1-core plus
shield) is:
Unbalanced connection BLU-80 connection
Pin 1: Shield
Pin 2 : Hot ‘+’
Pin 3 : Link to Pin 1
(Optional for BLU-80 inputs)
