Balanced vs Unbalanced: Difference between revisions

Line 22:

Whether or not a cable with a {{1/4 TRS}} plug is stereo or balanced (mono) or an insert cable depends on how it is being used and the electronic interfaces at both ends of the connection.

== Balanced Connections Preferred When Possible ==

:A balanced electrical signal runs along three wires: a ground, a positive leg, and a negative leg. Both legs carry the same signal but in opposite polarity to each other. Any noise picked up along the cable run will typically be common to both legs. Assuming the destination is balanced, the receiving device will flip one signal and put the two signals back into polarity with each other. This causes the common noise to be out of phase with itself, thus being eliminated. This noise cancellation is called '''Common Mode Rejection''' and is the reason balanced lines are generally best for long cable runs. XLR and Tip-Ring-Sleeve cables are used to transmit balanced audio from one balanced device to another.

:Unbalanced cables are less complicated, but they’re much more susceptible to noise problems. In general, unbalanced lines should be kept as short as possible (certainly under 25 feet) to minimize any potential noise that may be carried with the signal into the connected equipment.

== Connections between Bose Portable PA Devices ==

All line-level connections between Bose Portable PA are balanced. Where possible, use a balanced connection with a {{1/4 TRS}} or XLR cable. Using an unbalanced connection may lead to up to -6 dB lower signal.

* ToneMatch mixers: The analog outputs (Main and Aux outputs) are balanced

* Power Stands: The {{1/4 TRS}} inputs are balanced {{Model 1S}}, {{Model II}}, {{Compact}} channel 2 {{1/4 TRS}}

* {{S1}}: The channel 1 and 2 inputs are balanced

*For all [[:Category:Daisy Chain|Daisy Chain]] connections, use a balanced connection if possible. Most of the time that will be a {{1/4 TRS}}
