Audio & AES/EBU Input and Output wiring convention
Soundweb products provide cable shielding “back from the destination” to eliminate
ground loop problems. Therefore, 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
3088 connection
Pin 3 : Cold ‘-’
Pin 2 : Hot ‘+’
Pin 1 : Shield
This wiring can also be applied to the AES digital interface card.
Unbalanced wiring (analogue audio only) - The convention for unbalanced wiring to the
inputs (1-core plus shield) is:
Unbalanced connection
3088 connection
Pin 1 : Shield
Pin 2 : Hot ’+’
Pin 3 : Link to Pin 1 (Optional for 3088 inputs)
