Ground loop isolator – Beolab speakers & B&O devices (no guaranteed noise-free effect)

Suffering from hum or noise?

With some connections to receiver or TV, noise or hum may come from the BeoLab speaker,

with this ground loop isolator most grounding problems are solved.

Hum Noise with Beolab via CAT7

P54070
 

We often receive questions about hum noise in Beolab speakers when using CAT7 cables installed inside walls. These are commonly used with RJ45 to DIN8 (Powerlink) connections, but may result in unwanted noise.

The main cause is usually missing or incorrect grounding. Both Powerlink and Masterlink cables from Bang & Olufsen include shielding where the metal outer layer is used for grounding.

In many installations, CAT7 cables are connected using only the 8 internal wires, while the shielding/ground wire is not connected. Additionally, standard wall outlets are often not grounded, leading to interference.

For proper operation, it is essential to:

Connect the cable shielding (ground)
Use shielded RJ45 connectors
Secure the shielding to the metal clamps (strain relief) in wall outlets

Following proper grounding, as described in B&O Network Link documentation, will eliminate hum and ensure clean, interference-free audio.

Trigger hum or noise often occurs when connecting a cable to a receiver, especially with certain brands such as Marantz, Denon, and Rotel.

This Trigger Power Adapter solves the problem of hum and interference by galvanically isolating the receiver's ground.
This adapter is intended exclusively for connection to a Trigger output / DC-12V connection.
This grounding cable has been specially developed for use in combination with our trigger cables,
And is only suitable for the trigger cables available through our webshop.
