Terra Groundbox Grounding Device
Dear Clearaudio customer,
Thank you for choosing the Terra, a new grounding system by Clearaudio.
Every device in the household has the potential to introduce interference in the high-frequency range, which can be a potential disruptor for clean music enjoyment.
However, often the fault lies within the hi-fi chain itself, which can generate unwanted humming. This is usually due to a missing or incorrect grounding. The new grounding system Terra by Clearaudio is our solution to consolidate all necessary groundings at one point and leave possible ground loops in the past.
The star-shaped endpoint prevents any ground loops, and the sand-filled casing additionally protects against vibrations and interference. Through a special grounding plug, the device is grounded via the power outlet but is not directly connected to the electricity.
On the back of the Terra grounding device, there are three connections for direct grounding (grounded) and three connections with potential difference (ground lifted).
We wish you much musical enjoyment with your new Clearaudio Terra.

Remove the Terra from the packaging and place it in a suitable location.
Connect the grounding box and a suitable electrical outlet using the special power cord.
(Make sure that the wall socket you choose has an active protective conductor.)
Connect the ground wires
Use the included grounding cables to connect the respective end devices (e.g. turntable) to the Terra.
Make sure to connect all incoming ground connections uniformly to the ground connections WITHOUT potential difference (1a – 1c) OR to the ground connections WITH potential difference (2a – 2c).
It is possible to connect several ground cables per ground connection.
We recommend to initially ground all devices to the ground connection without potential difference.
If a hum can still be heard afterwards, all ground connections should be changed to the ground connections with a potential difference.
