Audio & Control connectors

3088 audio and control connections are via Klippon (also known as BL, Phoenix or

Combicon) pluggable terminal block connectors.
12 x 6-way female Klippon connectors are supplied for making these connections.
For audio and network cables and looms, see the Product Overview catalogue from:

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)
