Analog vs DigitalWhat’s the difference between analog and digital audio cables? Analog cables work by transmitting information through a stream of electricity, and digital cables work by transmitting information through a long string of 1’s and 0’s (aka binary code).In a home recording studio situation, you are mostly concerned with how to transmit the analog sound from your mics and instruments so that you can eventually capture the sound in your DAW or other recording app or software.

So, that is the key focus of this post.You can refer to to discover more about digital audio recording. What is the difference between Mic, Line, and Instrument level?Mic Level is the lowest signal level which travels through an XLR connection. The mic level signal requires a preamp to raise the mic level up to line level.

You use an XLR cable whenever you connect a microphone to your audio interface or mixer. Interfaces and mixers with built-in mic inputs usually have a built-in mic preamp too, so you shouldn’t need additional kit other than the cable.Line Level is the highest signal level which travels through a TRS connection. This is the standard type of signal and you should use TRS when connecting any non-instrument pieces of hardware to your interface (i.e.

An outboard preamp or processor) or instruments that output a balanced line level (synths, keyboards, drum machines etc). Note that a lot of consumer audio equipment and semi-pro keyboards etc may have unbalanced line outputs so you will use a TS cable instead.

Check the manual of your gear to be sure.Instrument Level is the most variable level signal which will travel through a TS connection. You will also require a preamp to be raise the level to Line Level. (Built in on most audio interfaces). Choose this cable whenever you connect an instrument such as a guitar or bass guitar directly to your interface. What Happens If You Send a Line Level Signal to a Mic Input?Mic levels are much lower than (typical) line-level signals. This means that any interface or mixer with a microphone as an input may be overloaded when you hit it with a line-level signal. However “overloaded” really means “distortion” rather than actual damage.

So, when trying to record, your equipment is not in any real danger, provided you are very cautious with the levels of volume.Start with the lowest output volume you can from the sending device, and gradually increase it so that you get a decent signal without distortion. You may find the recording result is perfectly satisfactory.

The problem you may experience, though, is a poor signal to noise ratioThe ideal thing is to buy an interface or mixer which accommodates both line and mic level. For example, the allows you to switch between line and instrument/mic level.

Understanding Analog ConnectionsYour goal is to record a clean and loud enough signal from your microphone, guitar, keyboard, synth, or drum machine in your recording software or DAW. Recording success has a lot to do with the audio cable types you choose. Get the audio connections right, and your audio recordings will sound good. So, how do you decide which is the right audio cable?As a general rule, you read what it says on your gear, or refer to the manual. Sounds simple?

Well, let’s start with an in-depth look at the most common audio cable types. Then we’ll examine the inputs and outputs on some popular home recording studio gear to see how it all fits together. You’ll soon get the hang of it.

This the audio cable or cord you use for your guitar, or for the left and right outputs of a synth or keyboard (assuming outputs are not balanced). It is mono because you only have one channel through which to send the signal. Either left or right. You cannot send a stereo signal through this audio cable.The most common TS cords are instrument cables. The instrument cable contains one wire and a shield. The wire is connected to the tip, the shield is connected to the sleeve. You need the shield to minimise noise.Instrument cords, or jack cables, are unbalanced because of the way they are wired.

The signal is sent through one wire. The shield is used for the ground. (ie it keeps the noise down).

More on balanced vs unbalanced later Meanwhile, here is one more thing you need to know. If you are connecting instruments, for instance, a guitar, a keyboard or a synth, then make sure you purchase an instrument cable. NEVER use a speaker cable to connect instruments.Most TS cables on sale are.

Just double-check before you buy. However, if you are connecting from your amplifier to a speaker or monitor, then do make sure you use a speaker cord. The connections look the same, but the signals are different strengths. The stereo TRS cable looks almost identical to the TS cable, but this 1/4″ jack plug has 3 contact points (the Tip, Ring and Sleeve) separated by 2 plastic dividers. Spot the difference?The TRS cable can be used in 2 different ways:.

As a stereo cord, where the signal is split into the right channel and the left channel. Generally the left-channel signal is attached to the tip, the right-channel signal is connected to the ring. Finally the shield is wired to the sleeve.

As a balanced mono cable to connect professional audio gear. For example, to connect a synth with balanced outputs to an audio interface with balanced TRS inputs. The benefit of a balanced cable is you can have a long cable run without creating noise. How will you know whether the outputs on your gear are balance or unbalanced? Your outputs will almost certainly be labelled if they are balanced or refer to the manual for your equipment to be sure. And read on for more detail.

Balanced vs Unbalanced CablesSo, what exactly is the difference between balanced and unbalanced cables? Does it matter? Here is a bit more detail, and a few useful things to know:. Unbalanced cables have a bigger chance of picking up radio interference and noise. If you were to cut open an unbalanced cable you’d see two wires: a conductor wire and a ground wire.

Therefore, use the shortest cables you can get away with. Balanced cables on the other hand are designed to cancel out those interferences and electrical hums. They do it with the help of an added wire inside, so they have two conductor wires and a ground wire (three in all). With the help of that second wire, both wires cancel out the noise. The balanced cable has two wires and a shield, when it is used as a balanced mono cable then the same signal is run throug both the wires. One signal is 180 degrees out of phase with the other.

When the signals get to the interface or mixer input, the signals are flipped and added to eachother. Thus, any noise built up in the signal is canceled out. For a connection to be balanced, allpoints in your cable circuit must be balanced.

Therefore: your gear must have a balanced output; your cables must be balanced (TRS or XLR); your input on your interface or mixer must be balanced. If just one of these is unbalanced, it’ll make your entire signal chain unbalanced. It is most likely that the 1/4″ connections are unbalanced, unless they are labelled as balanced. Check the manual, or the label on the input to find out. If the output is balanced mono, or stereo, use TRS. If unbalanced, and mono, use TS. It is wise to keep unbalanced cable lengths under 6 feet (1.8m) to prevent noise and interference.

If you need/want to use longer cables, or you want to connect an unbalanced signal into a balanced signal, then you can use a. This is a device used in recording and live audio to convert signals and match audio levels. It allows you to plug unbalanced gear (such as your guitar, synth, or bass) to balanced inputs on mixers and PA systems. Because the DI box converts the signal to a balanced connection. You get noise reduction, no interference and the ability to run long cables. RCA cables, sometimes referred to as phono plugs, or phone cables, are common on home stereos and a lot of semi-pro audio gear.

They function very much like TS cables, with one connector and one ground. The RCA cable is an unbalanced cable. RCA connectors usually come in pairs to achieve stereo. Most of the time the red is used for the right channel (easy to remember: red- right) and white is used for the left channel.Keep your RCA cables is short as possible, else you might pick up noise and electrical hums. You will mostly find the four-conductor tip-ring-ring-sleeve (TRRS) in use on tablets, smartphones, and laptops. Note how there is an additional ring on these jack plugs.

The extra ring provides an additional audio channel. The TRRS combines microphone input, as well as stereo heaphone output.

(If you use the appropriate equipment).Nearly always, a TRS 3.5mm headphone plug will work in a TRRS socket, so you can listen to the audio output. But if you have the additional ring on the plug, and a mic on your headphones, then you can use your headphones like a headset. The upshot of this kind of port is if you want to record on your phone, laptop or tablet without an interface, you can do so if you have a mic with a TRRS plug, like the or similar. Digital CablesYou will find more and more digital cables in a modern home recording studio.

In some ways, digital cables are more straightforward. This is because unlike analog cables, with digital cables you don’t really need to understand much about how they work, in order to use them.

You simply purchase the correct cable according to the protocol: ADAT; S/PDIF (also known as TOSLINK); BNC; and AES/EBU.To keep this post simple, we are concentrating on analog cables and only 3 most common digital cables found in a home recording studio situation. If you have an audio interface or pro audio gear with digital connections, then refer to the manuals of the devices so you purchase the correct interconnect. You will also find useful information in our post on.Here is a roundup of the digital audio cables you will find most often in a home recording studio. MIDI cables are used to sync and communicate instructions between MIDI compatible gear. So, your digital piano or electronic drum kit will almost certainly have MIDI i/o. Many modern MIDI devices now use USB to connect. However, you may find it more efficient, even if USB is an option, to use the traditional MIDI ports on your equipment, and connect them with a MIDI cable.

You can find out more about this protocol in our detailed post on.The MIDI cable has 5 pins. You may see the MIDI cable referred to as a 5-pin DIN cable.

USB (Universal Serial Bus) is a common way to connect devices in a home recording studio. The majority of audio interfaces connect via USB. As do many MIDI keyboard controllers.

Digital pianos and music keyboards often have a ‘USB to Host’ connection for MIDI.Most interfaces and keyboards connect via the USB B to A as shown above. (It’s a standard USB printer cable). However, many USB mics and some interfaces have a mini USB port. Often you will get a USB cable in with the audio device, but if not it is a simple matter of checking the connections and ordering the correct cable.USB has different standards, as follows:. USB 1.1: this original standard can handle a data rate of up to 12 Mbps (megabits per second).

USB 2.0: Also called High-Speed USB. This can handle 40 times the data flow of the older standard.

480 Mbps. USB 3.0: Also referred to as SuperSpeed USB. This connection transfers data at 5 Gbps, ten times faster than USB 2.0As there is more than one standard, do check the ports on your computer and your interface or device, so that you purchase the correct speed of cable.Incidentally, a is not just a connection cable. It has MIDI connectors on one end, a USB connector on the other, and an interface between the two to allow the communication between the MIDI instrument and the MIDI software, via a USB port.

Thunderbolt offers unprecedented data transfer rates, previously only seen on dedicated PCIe processing cards.However, before you get too excited, it’s important to check which protocol your computer’s ports support before purchasing peripherals (such as an audio interface) to ensure correct compatibility.

Multiple choice java swing. I am creating a Multiple Choice Test with WindowBuilder for a school assignment. I am nearly done, however, I am having trouble with keeping score. The score does not seem to add up. I'm using two classes to create the multiple choice test. If anyone can help me set up the score system that would be greatly appreciated. Answer: (d) 60, 30, 0, 20, 0. Explanation: In the above code, there are two values of variable a, i.e., 10 and 60. Similarly, there are two values of variable b, i.e., 5 and 30. But in the output, the values of a and b are 60 and 30, respectively. It is because of the execution order of the program.

For example, the 2016 Apple ‘MacBook Pro’ models each feature Thunderbolt 3 ports as the only method of device connectivity. The 2015 Apple ‘MacBook Pro’ features Thunderbolt 2. Conversely, the 205 Macbook (not Macbook Pro) features USB 3.1 as the only method of device connectivity, though the ports appear to be identical.In general, you should assume that any ‘Type C’ ports on any computer are USB 3.1 only unless the Thunderbolt logo appears next to them, or the manufacturer states it is Thunderbolt.Thunderbolt 3 is a new connectivity standard from Intel that replaces Thunderbolt 2. The Thunderbolt 3 port provides a theoretical maximum throughput of 40 Gbps, which is double the speed of the previous standard.

It is also is symmetrical and reversible. As a result, you no longer have to worry about whether or not a connector is right side up or upside down before plugging a cable into the notebook.It is easy for you to confuse the difference between Thunderbolt 3 and USB-C.

No doubt this at least partially is because the ports look identical apart from the “traditional” three prong USB logo on USB-C cables and the “Lightning Bolt” logo on Thunderbolt 3 cables.The simplest explanation is that USB-C refers to the shape of the port and Thunderbolt 3 refers to the connectivity standard. Thunderbolt 3 combines Thunderbolt, USB, DisplayPort and power via a single USB-C connector.So, you connect a Thunderbolt 3 device to a “Touch Bar” MacBook Pro using the Thunderbolt 3 standard via a USB-C shaped port. Hardware commonly referred to as “USB-C devices” also will work with a Thunderbolt 3 port, but they will not be able to take advantage of the maximum speed provided by Thunderbolt 3 devices. Front panel: As you can see, the interface has balanced inputs on the front.

You can connect microphones via XLR cables (a balanced signal). You can connect balanced line level signals using TRS 6.35mm jacks cables.

Or, you can record guitars or other unbalanced line or instrument level devices via 1/4″ TS cords.The output requires a 1/4-inch TRS stereo jack.Rear panel: This audio interface has MIDI ports for MIDI in and MIDI out. There are two sets of unbalanced outputs, left and right. These are of the RCA phono type.There are also two balanced line outputs. These require TRS 6.35mm cables to connect to either an amplifier. Finally, as you can see, this is a USB interface, so there is a USB output to connect the device to a computer.
