CAD GC3.1 Ground Control

If you are outside the UK please contact MCRU before purchasing any CAD product, thank you.

How it works

Passive operation:

The Ground Control is a passive device, meaning it has no active electronic components and does not pass current.

Internal composite:

It contains a proprietary composite “sandwich” of specialized materials that absorb high-frequency noise and convert it into heat.

High-frequency absorption:

The materials are effective over a wide frequency range, from the very high kHz range to over 10 GHz.

Purpose and application

Reduce high-frequency noise:

The primary goal is to reduce high-frequency noise that can degrade audio quality.

Connect to audio components:

It connects to any audio product with an unused output or input, like RCA, XLR, or USB.

Connect to Earth ground:

It can also be attached to the Earth connection of your audio system, such as a metal case screw or a dedicated earth post.

Ideal for noisy components:

It is particularly effective with noisy components like servers, phono preamplifiers, and preamplifiers that are sensitive to high-frequency noise.

Key features

Multiple connection sockets:

The GC3.1 features six 4mm banana sockets on the back for connecting to multiple audio components.

Low-impedance cables:

Connecting the Ground Control requires specialized cables designed for low-impedance high-frequency noise.

Additive effect:

The sonic improvement is often additive, meaning the more components connected to the Ground Control, the greater the overall effect.
