CAD Ground Control Cables

CAD Ground Control Cables

Regular price $350.00

The CAD GC1, GC3 & GC-R Ground Controls can be connected to any audio product that has an unused output or input connection. If your DAC, streamer, computer, phone stage, preamplifier, amplifier, CD Player, NAS, etc. has a spare output/input connector like an RCA, XLR, Spade, USB or BNC you can connect the Ground Control to that. We supply a range of interconnects with various connectors. The other end of the connector has a single 4mm banana plug that attaches to the Ground Control.

There are two 4mm banana sockets on the back on the GC1, six on the back of the GC3 and eight on the GC-R.

The GC1, GC3 or GC-R Ground Control can also be attached to Earth. If you have any type of Earth connection on your audio system or power distribution CAD can supply you a cable with an appropriate connector that will fit. The outside case of any audio component that is made from metal by law must be connected to Earth for safety. So another option is to attach a Ground Control to the case directly by loosening a case screw and inserting a Ground Control cable with a spade connector.

We typically get the best results connecting the GC1 Ground Control to the device in your system that has the highest noise levels: components like computers, audio servers, DACs, CD players, NAS, routers etc. or by connecting the GC1 Ground Control to mains Earth. These are the best places to first try connecting the GC1 to. The GC3 & GC-R work exceptionally well connected to your mains Earth connection and directly to the cases of your amplification.

We also have had very good results connecting a Ground Control to phono preamplifiers. The gain on these devices is large and the reduction of noise that the Ground Control provides has brought some amazing results.

Note: Amplifiers

We do not recommend attaching Ground Controls to the output of audio amplifiers unless you completely understand the technical design, or the amplifier can be damaged

Our results have shown that better sonic results are typically obtained by connecting Ground Controls to source components, preamplifier or an unused input of an amplifier.

But, if this is not possible and you wish to connect a Ground Control to the output of an amplifier (especially a balanced design) you must follow these rules:

  • Never connect a Ground Control to a positive output.
  • If you connect a Ground Control to the negative output NEVER connect the Ground Control to anything else. It is safe if you connect a Ground Control to the negative output of your amplifier only if the Ground Control is NOT connected to anything else.  If you also attached the Ground Control to another component or to Mains Earth you may short your amplifier and damage will result.

We are excited to announce that an interconnect company (that CAD really likes) called Bibacord is now making interconnects so that a Ground Control can be linked directly to the shield/screen inside the cable.  In this arrangement you have a Ground Control connected to the screen/shield along the entire length of the cable.  The reduction in high frequency noise in the interconnect produces what we feel is a more natural, larger sound stage with increased detail of an already amazing cable.
