cable connections must be made. For a digital stereo signal, only one
cable connection is necessary.
Usually you will want to test all the inputs and outputs of your device
under test, whether they are analog or digital. Analog inputs to the
device should be connected to the analog outputs of the test
instrument. Analog outputs from the device should be connected to
the analog inputs of the test instrument. The digital input to the device
should be connected to the digital output of the test instrument. The
digital output from the device should be connected to the digital input
of the test instrument.
If your device has both digital and analog inputs and/or outputs, the
digital and analog connections may be made simultaneously.
However, you should never connect more than one digital input at a
time.
Balanced vs. Unbalanced
Another major division exists between balanced and unbalanced
connections. Most consumer devices use unbalanced connections.
Most professional devices use balanced connections.
Unbalanced connections only require two wires: one to carry the signal
and one to carry the ground. Balanced connections require three
wires: two to carry the signal and one to carry the ground.
Balanced connections are generally used in professional applications
because of their higher immunity to interference and noise.
Unbalanced connections are generally used in consumer applications
because they are less expensive.
The most common unbalanced connectors are the RCA connector, the
BNC connector, and the 1/4" Phone connector.
The most common balanced connector is the XLR connector. XLR
connections are almost always balanced, although sometimes the XLR
connector can be used in balanced or unbalanced configurations.
