			;Note:
			An unbalanced connection can be -6 dB lower signal level than a to balanced connection.
			=== Background Information ===
	: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.		:A balanced electrical signal runs along three wires: a ground, a positive leg, and a negative leg.

	: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.		:Unbalanced cables are less complicated, but they’re much more susceptible to noise problems.

	If you connect a stereo signal to a balanced input, you may hear very little, or just effects with none of the original signal.		If you connect a stereo signal to a balanced input, you may hear very little, or just effects with none of the original signal. A balanced input will take the left and right signals from a stereo source and combine them with reversed polarity (this is how balanced connections work). The result is sounds that are panned in the center (typically, vocals, drums, bass) will be cancelled.
