Type and usage of important audio cable

  1. 1. Type and usage of important audio Cable My name is Sebastian La Rocca, I`m from Buenos Aires Argentina. I`m a musician composer and I`m going to talk about the most important type of cables and connectors that we can use in a standard studio or home studio. This lesson is for week 1 of Introduction To Music Production at Coursera.org The most commons cables that we going to use in studio are. -TS cable-connector ¼ inches -TSR cable connector ¼ inch and 1/8 inches -XLR cable conector -RCA cable conector First I present the material talking about the configuration or system that they have. Then I will describe each one of these cables. These 4 cables connectors are divided in 2 categories – Balanced connection – Unbalanced connection The TS cable and RCA cable are unbalanced connection, that is a system or configuration that uses two wires. One wire carries the audio signal (single conductor) and the other connects to the ground, or shield.
  2. 2. Because of this configuration or system, this cables are susceptible to noise, so we have to use short cable, if we have a long unbalance cable like a 20 foot long cable, it`s going to be like an antenna. So we use short unbalance cables on studio or on stage. These cables are Mono (single conductor), so if we need a stereo signal we need two cables or two connectors. Like the photo, two mono unbalance in one side, one balance stereo in other side.
  3. 3. The unbalanced connection is used for high impedance microphones and pickups, like guitar or bass pickups, piezoelectric contact pickups or cheaper microphones. The TSR cable and XLR cable are balance connection. That is a three wire system, two carries the signal, and the third is the ground or shield. The balance connectors are more immune to noise than unbalance. The more popular of this two is the XLR, because it has 3 conductors, it’s shielded, it´s lock in place and don’t move, and the ground pin contact first than the other two pins to avoid pops. Balance connections are use for low impedance microphones. This is the right type of connection on studio and on stage for microphones. Most professional Microphones are low impedance devices.
  4. 4. There is a useful device in studio and on stage, called direct box, where an unbalance signal that we plug in the Input side, came
  5. 5. out balance from the Output side. In the Input side we have two TS connectors in parallel, one for plug an instrument and other to connect an amp. On the output side there is a XLR connector, as we see in this picture. Now I will describe every type of cable: – The most popular is the TS cable or Instrument cable, it’s an unbalance connector. TS means: T for TIP, where it goes the only one signal (single conductor), and S for Sleeve, where is the ground or shield. The connector has these 2 parts. It is use to connect guitars, basses, mics preamps and pieces of studio gear. See picture below.
  6. 6. – A variation of TS is the TSR cable connector. It is a balanced connector with 3 parts: 2 conductors and the shield. TSR means TIP SLEEVE and RING. Its is an Stereo connector that transmit two separated signals. . The TIP is the left, the Ring is the Right, Sleeve is the shield. It is common to use these connectors in headphones. It is less susceptible to noise than TS cable.
  7. 7. – The XLR cable connector is the most stable connector on studio we can have, and we use it for microphones and for connect Direct box. It is a balanced connector that has 3 pins, two for signal and one for shield. It is very useful for long ride cables, because it has build to avoid the noise.
  8. 8. – The RCA cable connector is like a TS, It is mono signal, have two parts, conductor and shield and it is used for home video devices. In Studio I used with an adaptor to plug in a console. Two cables to recreate the stereo signal. – The variation of TSR ¼ is the 1/8 inch stereo cable. It is used for headphones as well as the TSR, same configuration but smaller. – The last cable that I want to introduce you is a Midi cable. One in particular that I have is Midi in one side and USB in other side. It’s very useful in home studio like mine. The type of signal that transports is one and zeros, just transport data.
  9. 9. Finally I would like to say a few tips to recommend for those who have a home studio or standard studio, a kind of conclusion of this review. – Get good quality of cables and connectors. – Get a variety of adaptors; they are always useful to have it in studio. – Get more than one of each cable, although we think that don´t needed.
  10. 10. – Get variety of combination of connectors, like we saw in pictures. Thanks for read my work and I hope it has been helpful for you to understand this area. And I appreciate your critics and opinions. Sebastian
