Ground referenced connections
Many unbalanced signals are passed between pieces of equipment where one of the
devices is balanced and the other is not. By careful wiring using two-core cable with an
overall screen, it is possible to convert this connection so that it operates in a similar
way to a balanced system, with a ground reference that is not corrupted by ground loop
currents in the shield. One conductor carries the signal from the unbalanced device to
the hot connection on the balanced unit, while the other conductor carries the ground
as a reference from the unbalanced device to the cold connection on the balanced unit.
The screen is connected at the unbalanced end only. This referenced connection works
for balanced to unbalanced and vice versa.
Ground referenced insert wiring diagram. For a typical example of how to wire a
ground referenced insert, see Figure 1 on page 15; the example above shows the
screen connection at the other end because it is more practical, as it reduces the wiring
complexity within the 1/4” TRS Jack connector.
To save space and cost, as is typical for consoles at this point in the market, all inserts
on the VeniceU are unbalanced, with send and return on the same jack. When
