Now pan one track completely to the left, the other to the right. The tracks should be almost identical but just different enough to give you a rich wide sound that can not be achieved by using a single mono track.
Great sticky. I have been looking for infomative articles on home recording interfaces.
You have the Tascam US-1800 listed as having 16 in / 16 out. Tascams site says 16 in / 4 out.
This is correct, what happens at the Input is.. there is an electronic circuit called a Difference Amplifeier which will amplify the Difference between the two signals . Any noise / electrical interference coming from other equipment like lights ... would be found in phase on both of the signal wires , because the Difference Amp circuit only amplifies the difference between the signals on the two wires it thus filters out the Noise / Electrical interference because this is not out of phase on the two wires......

Great article! Thanks for sharing this and making it easy to understand. I know that as a newbie I have really no say in this but this should really be made a sticky for the likes of me Just 2 quick questions:
1) What are/what is the difference between "unbalanced" and "balanced" inputs and outputs?
2) Why do many interfaces have so many excess analogue and digital SPDIF outputs?
the two wires carrying the signal are identical and the screen is used only for taking away unwanted interference. An unbalanced cable will commonly use a single coaxial core screened wire which uses the screen as the return path for the cicuit and, as the screen and the centre wire are not identical will not be balanced electrically. The impedance of the two will be different.
Outputs from an interface are selectable line outs 'from' the recording software 'after' recording. If an interface has 8 inputs, they are sent to the computer via USB or Firewire cable. This confuses many. Say in interface has 16 ins and 4 outs, that means it will record 16 separate tracks at once, but only send out 4 separate signals for monitors or outboard gear. Make sense?
