Entreq Magneus Signal

Magneus Signal is a semi-passive electromagnetic field transformer designed for network, USB, and HDMI cables. It calms the field environment around your signal paths, helping sources sound clearer, more focused, and more relaxed — all without any electrical connection.

Magneus Signal is a semi-passive electromagnetic field transformer designed to reduce the impact of unwanted high-frequency noise and field interactions travelling along audio cables — whether digital or analogue. Simply placed on the cable, it works without touching the signal itself, shaping and calming the electromagnetic environment around the conductor.

Why Choose Magneus?

Most audio systems suffer from electromagnetic field interference entering through power and signal connections — yet this issue is rarely recognised and cannot be solved by upgrading components alone. Magneus addresses this hidden problem at its source. It is the only product of its kind available in high-end audio, developed from Entreq’s decades of research into electromagnetic behaviour in music reproduction.

Where to Use It

Magneus Signal performs exceptionally on network, USB, HDMI, and analogue interconnects, as well as on Eartha Ground Cables connected to an Entreq Ground Box. These cables can act as conduits for interference entering from outside the system, affecting timing, spatial cues, tonal integrity, and overall musical engagement.

• Between network switch and streamer
• On USB audio links and HDMI signal chains
• Between analogue sources and preamplifiers
• Between preamplifier and power amplifier
• On Eartha Ground Cables

How It Works

Magneus Signal is not a conventional filter, absorber, or shield. Instead, it uses a carefully engineered blend of paramagnetic and dielectric materials to shape the electromagnetic fields around a cable, reducing high-frequency instability and vagabond currents without altering the signal itself.

Unlike ferrite rings, which absorb noise in a narrow frequency band, Magneus Signal works in real time to guide and balance both magnetic and electric fields. Its open internal geometry and material mix are tuned to create a calmer, more coherent signal environment.

Audible Results

Expect improved clarity, enhanced low-level detail retrieval, greater spatial stability, and a natural, unforced musical flow. In both digital and analogue paths, Magneus Signal reduces glare and fatigue, helping music breathe with better separation and tonal purity.

System Integration

Magneus Signal complements other Entreq field-shaping products like MaxMix T2, as well as our grounding boxes. Together, they help create a more coherent and quiet signal environment from source to speaker, without modifying signal flow or requiring any power.
