The Computer Audio Design Ground Control manual explains how to connect the passive GC1 and GC3 devices to reduce high‑frequency noise in audio systems.
The Ground Control is a passive device that reduces high‑frequency noise in audio systems by absorbing and converting it into heat. It is available in two versions: the GC1 with two sockets and the GC3 with six sockets, each internally connected.
The manual provides step‑by‑step instructions for connecting the Ground Control to source components, pre‑amplifiers, power amplifiers, and mains earth. It also details the supplied cable options, safety considerations, and how to daisy‑chain multiple units for increased effect.
| Device type | Passive (no power required) |
|---|---|
| GC1 sockets | 2 |
| GC3 sockets | 6 |
| Standard cable terminations | RCA, USB, XLR, Spade, 4 mm banana |
| Ground Control connector | 4 mm banana plug |
No. Connecting the output of a power amplifier to a Ground Control can possibly damage the amplifier.
The GC1 version has two sockets.
Standard terminations include RCA, USB, XLR, Spade and 4 mm banana plugs.
Yes, using short jumper cables you can connect two GC1 units together to increase the effect.
