On the first diagram, it is a live sound setting. It has 4 sound sources which are vocal, guitar, keyboard and bass guitar. For vocals, I used a XLR cable because microphone uses XLR outputs/inputs. The XLR cable is connected directly to the mixers XLR output. The XLR will carries the analog signal that is balanced to the mixer so that no interference or buzz sound would occur. The next sound source would be the guitar. The guitar is first connected to the guitar amplifier by a TS cable that carries a mono, analog and unbalanced signal. Because it has a unbalanced signal and to clear the unwanted buzz sound, the guitar amp is pre-mic so that the buzz sound is cut off and sent directly to the mixer by a microphone that is capturing the sound. The next sound source is the keyboard. The keyboard is connected to the keyboard amplifier through a TRS to 2 x TS ( Y cable). They keyboard has two mono signal which is L and R so the TRS to 2x TS y cable would be able to send all the signal to the keyboard Amplifier. The keyboard Amplifier is also pre-mic so that the unwanted buzz sound is cut off too. For the 1/8 to 2 TS (y cable), is connected from the mixer to the headphones. A 1/8 is a headphone jack and it sends digital signal to the headphones. The TRS cable is connected from the mixer to the monitor speaker. The TRS cable carries a digital and stereo signal to the Monitor speaker which produces stereo sounds. The next wire which can be seen in the second scenario is a Fire wire which is Studio recording Sessions. The fire wire is connecting the MIDI keyboard to the computer. It sends digital signal to the computer as the computer can only receive digital signal. The computer would be able to receive the performance data from the MIDI keyboard. A pre-amp is connected to the interface by an Optical Cable. An optical cable sends data by reflecting light so that much digital data or multiple tracks could be send at the same time and at a faster rate. The interface has an adat port which then converts all those light signal information into digital binary code so that the computer could read all the information.
