any recording studio will have bags and bags and even cases of different types of audio cables, enabling them to prepare for any situation.
Cables, while sturdy, are like computers and may break down at any time.
i know you have a simple phone-line jack (pl jack or ts) for your instrument and probably know about your xlr male and female connector from your microphone in your home studio.
五福彩票安卓版下载“if you’re recording music on a acoustic guitar and without a complete medley in an actual studio, you just need your usb cable, one ts jack and your xlr connector to your interface.”
however, if you plan to expand, it’s time you learn about cables first.
11 connections you can find in the recording studio
1. Analog and Digital
Converting Audio To Computer Language
Analog cables, such as your PL/TS jack and your XLR connectors work by transmitting electricity.
this makes it possible for mixers to send phantom power to condenser microphones where applicable.
the magnets in microphones and electric instruments transmit electric pulses that are audio energies captured through vibrations.
Digital cables used in computers transmit open and closed signals, represented by 1 and 0.
every character in the computer, even letters, are strings of these binaries.
五福彩票安卓版下载programming languages allow the simplification of these strings for creating programs or making the computer process other functions.
an audio interface allows you to convert your audio signal into digital while preserving the analog signal’s characteristic.
this technology had enabled plenty of home studios to begin their audio projects and create professional-level results!
2. The Role Of The Audio Interface
五福彩票安卓版下载Your audio interface, converting analog to digital sounds, also functions as your recording mixer.
in the old days, the mixer was the audio interface.
mixers directly streamed to signal processors, which connected to tape recorders of the old.
Now, audio interfaces have analog to digital converters processed through USB and shown in the arrange window of your DAW.
五福彩票安卓版下载audio interfaces vary from a simple two-channel mixer with a usb connector to your computer to advanced hardware complete with different ports for specialized cables, which we will discuss later.
五福彩票安卓版下载some audio interfaces have their own signal processing chain similar to daw plugins you use for your tracks.
These types of audio interfaces also have their own computer processors, enabling you to use VST plugins without overloading your computer CPU.
3. The Actual Cables For Audio
i know what we discussed isn’t about cables, but it’s great to know the principles and even your audio interface that directly interacts with your cables, microphones and instruments.
Stereo and Mono: There are different connectors and cables that transmit either mono or stereo.
in the following guide, we will explain the differences and functions of these.
五福彩票安卓版下载still, more useful information…
4. Signal Levels
五福彩票安卓版下载microphone levels are often balanced.
五福彩票安卓版下载however, they are quite weak because they’re the vibrations of the diaphragm that captures performances.
magnets have to be energized to improve their performance; hence, a microphone preamp is essential.
most microphones can have preamp from mixers.
some manufacturers provide microphones their own power supply for ‘cleaner’ signal processing, meaning less to no distortion.
the microphones then reach line level.
五福彩票安卓版下载instrument level signals come from pickups of electric instruments such as guitar and bass.
these are direct-line signals to be processed by a direct box.
in some occasions, your own audio interface serves as a direct box by providing a line-in specifically designed for direct-recording instruments.
it automatically boosts instrument levels to line levels.
depending on the quality of your audio interface, the instrument signal could be clean or a bit distorted or colored, which could or could not work to your advantage.
五福彩票安卓版下载reaching line-level signals means ‘cleaning’ specific signals by using different cables.
五福彩票安卓版下载unclean signals, which bring out certain artifacts from various sources, will also be raised at line level.
the knowledge of different cables is essential because you’ll know when to use noise-canceling cables, when your cable has a rupture introducing certain signals into your microphones or instruments.
line level artifacts cannot be removed in the post-processing phase, so use only high-quality cables appropriate for the job.
be aware of your signal chain.
yes, even bad usb cables can introduce line-level signals.
trust me; i’ve been there.
5. Balanced and Unbalanced Cables
Balanced signals: are useful because they cancel noise, reduce artifacts, and create a consistent signal.
Unbalanced signals: have varying electric voltages that could affect the final sound of an instrument or vocal performance.
- Acoustic and electric instruments are not designed to possibly have a balanced signal as often as possible. Using a direct box converts the signal to line level that allows you to process them effectively.
- Direct boxes have XLR inputs that allow microphones to enjoy the same features where needed.
“of course, you could always have preamps to help do this. but during times of improvisation and a lack of gear, you’ll thank me for this tip”
6. The Types Of Analog Connectors out there
Cinch and Coax: Also known as RCA Jack; you will find these type of connections on HiFi systems.
these connectors can transmit audio and video signals.
五福彩票安卓版下载these types of connectors can still be found in a lot of dj equipment.
they have always been color-coded for ease of use, you might know them already.
Red = Right audio channel
White/Black = Left audio channel
Yellow = Video Signal
Orange = Digital Coax (Digital RCA transmits Digitized audio)
XLR: are your standard-issue microphone cables and connectors. Also known as Cannon plug back in the days.
they are thicker than instrument cables because they house a positive, negative and ground wire.
五福彩票安卓版下载these cables cancel out noise by introducing a balanced sound.
better coiled and a bit more expensive than ts and trs cables, xlr cables are well-suited for live performances.
because of their ground wires and sturdy build, xlr cables are not just for studio use.
live performances rely heavily on xlr cables even for instruments due to their noise-canceling and signal preserving capabilities.
- Male XLR comes with three pins
- Female XLR comes with three holes
TRS: are more affordable than XLR cables and have no need for special inputs. These connectors often fit into any type of TS input/output.
trs stands for tip, ring and sleeve, the three parts that make up the cable. ts only has a tip and sleeve.
The third point in the TRS connector is a negative signal五福彩票安卓版下载 that opposes the positive signal of the tip, canceling out noises and maintaining a balanced signal.
they have three contact points but ts only has two.
Also known as Jack Cables, you can find these in mono and stereo versions.
But the mono versions are mainly used in the studio environment. A example of use: Guitars or Monitor speakers.
Warning: When connecting a TRS to your audio interface make sure that you know which source you are connecting.
a keyboard, synthesizer or guitar needs a “di” or a dedicated instrument input.
五福彩票安卓版下载these transformers will then bring the signal back to line level. a synthesizer or equivalent will be using two mono jacks.
五福彩票安卓版下载 Sleeve: Ground
3.55mm Stereo Jack:五福彩票安卓版下载 These are mainly used for headphone connections.
you will find them on laptops, tablets and pc’s. they are stereo transmitters and function the same as there bigger 6.5mm jackplug brother (the trs).
TS: Tip-Sleeve cables are standard issue for instrument connectors.
五福彩票安卓版下载typically carrying a mono signal, ts cables are usually cheap to high-quality because they are more affordable than most cables.
五福彩票安卓版下载however, they are to be used only for instruments.
during recording, balanced cables are immensely a must. they only have two contact points.
AES/EBU: This is a professional version of the Coax cable. It transmits digital signals on 24bit with an impedance of 110ohms. It uses an XLR connector and it’s equivalent would be the S/PDIF (read about that later).
7. Digital & Computer Cables
“now we’re done discussing analog signal cables. moving on, are essential computer and audio interface cables that efficiently convert your analog to digital signals”
yes, most of these cables do not transmit noise and are made of affordable but high-quality materials.
however, the ports in your computer and your audio interface interact differently with each other depending on the type of cable you’re using.
the more special and specific the cable, the more it can transmit and receive signal quickly.
Here’s the digital cable guide.
MIDI Cables: Of course, you knew about this and you’ve been using it to wire together your keyboards and keyboard controllers五福彩票安卓版下载 to each other or to audio interfaces.
五福彩票安卓版下载midi transfers note control voltages to synthesizers, which turn raw digital signals into recognizable musical notes.
五福彩票安卓版下载the musical instrument digital interface does not only transmit note cvs but also velocity information, the relative impact of the keyboard to the floor, which helps add dynamics to instruments.
midi cables connect to the five-pin slot at the back of your audio interface or even your classic midi interface.
USB:五福彩票安卓版下载 is the most basic digital cable that allows your audio interface access to your computer.
However, because of its slow data transfer, it works well for home recording studios which use microphones to record vocals五福彩票安卓版下载 to instruments.
五福彩票安卓版下载the slow data transfer is essential if you’re recording with virtual studio technology (vst) such as emulated amplifiers.
五福彩票安卓版下载while useful for transferring information from one data storage medium to another, usb technology functions efficiently for such function alone.
Firewire:五福彩票安卓版下载 is fairly common with expensive interfaces and high-end computers.
五福彩票安卓版下载it has significantly faster data streaming speeds than usb 2.0 ports.
they are often used by high-end, multiple channel and fast-powered interfaces.
usually, windows laptops cannot use firewire as it has no firewire port available.
五福彩票安卓版下载pcs on the other hand could find a card with firewire ports.
五福彩票安卓版下载this is essential if you are upgrading to bigger and better hardware for your home studio.
Thunderbolt:五福彩票安卓版下载 Commonly used by Apple and used by the newer, high end interfaces, Thunderbolt pars with PCI processing cards when it comes to speed.
data transfer and streaming is quick and reliable, with complete stability.
五福彩票安卓版下载apple used the thunderbolt technology to surpass the usb’s ‘data transfer only’ function to allow their devices to cast screens, control the laptop remotely or do high-speed transfers between devices for software interaction.
8. Optical Connectors
S/PDIF and Toslink:五福彩票安卓版下载 The Sony/Philips Digital Interface Format commonly used in hi-fi systems manufactured by the two companies aren’t left out of the audio engineering loop.
also known as toslink, it carries 2 channels of audio transmitted by fast light signal pulses instead of low current.
it’s interior is made of fiberglass, an can transmit only one stereo signal. it’s widely used for consumer hifi products.
五福彩票安卓版下载however, it wouldn’t connect your interface to your computer.
instead, it sends your mix towards your hardware rack effects and processing equipment, if any.
ADAT Lightpipe/Optical Interface: ADAT cables sound funny because it’s like somebody inverted pronouncing DATA or something.
however, adat cables are optic-fiber cables capable of carrying multiple channels of digital audio through a single cable.
it’s like your usb or thunderbolt, except it uses light rather than electricity to transmit signals.
五福彩票安卓版下载a single adat cable carries about 8 channels at a high sample rate of 48khz or four channels of audio at 96khz.
pretty neat, i must say…
五福彩票安卓版下载“high-end audio interfaces use adat cables to interact with a multi-channel microphone preamp, perfect for drum tracking and multi-vocal recordings”
9. Lightlead – Optical Analog
electronic instruments like guitars and keyboard have been connected with cables that incorporate braided copper wire.
these types of cables can give weak signals that can introduce interference like hum and noise.
besides that: the length and the quality of metal all must taken into account when talking about quality signal. iconic sound has come up with a new solution “the lightlead“.
this is an optical system that sends analog signals via instrument cables through line level. there is no modulation or digitization and there is no loss of delay within the signal.
it’s thin flexible and sturdy! the only downside is the price and the use of batteries for this type of system! it’s still fairly expensive.
10. Other Cables Used In Studios
bnc cables: are your typical television or modem cables that use optic fiber technology to transmit information.
however, their job is to sync your audio interface with the clock of your computer or other equipment to align all samples and reduce latency while reducing those annoying clips and pops that occur during recording.
五福彩票安卓版下载this is usually used during live recording setups wherein bnc cables are used for advanced signal routing wherein lossless data integration is important.
cat5e: your dsl modem or your telephone may be operating with the same cable.
五福彩票安卓版下载cat5e cables are useful in the studio to send power and stream multiple audio channels by just using a single line.
“usually used in live recordings or orchestra snapshot recordings with multiple channels of recording required in one sitting, cat5e cables are quite expensive”
they’re not your regular modems though, but they can be used with your land-line phone. yup, i’ve tried it!
of course, your power cable is important. the cable used for mixers as well as some personal computers and other audio and non-audio equipment is the iec c13.
五福彩票安卓版下载you could buy this at your local hardware store if you need one. but i doubt you’d have to if you have tons of equipment in your studio to begin with.
11. Organizing & Labeling
五福彩票安卓版下载most studios find themselves entangled during recordings. i mean literally. even in my own studio, i find wires scattered all over and i always tell myself that one day, i’m going to fix everything up.
when that day came, i didn’t know what to do. but anyway, i figured that it’ll do lots of work to combine my cables into a single snake cable.
i find it important to label cables.
五福彩票安卓版下载sure, every cable is different in appearance, but you want to save time and yourself from headache from fiddling with cables.
五福彩票安卓版下载a snake cable, similar to what data servers do with multiple data cables, allows you to label and quickly find hardware problems you might have in the studio.
we’re at the end of our journey with different audio cables. i believe you might have learned a thing or two from this little tutorial.
五福彩票安卓版下载if you have a small studio or a home studio in your bedroom, cables won’t be much of a problem. audio equipment stores are selling them in singles or bundles, so if you lose any cable, just head there or you could even buy online.
五福彩票安卓版下载always remember to label your cables first before you insert them. i must admit that daw cable wiring has made me feel lazy when i’m wiring my rack processors, but it is bad practice to not label your cables. if you lose yourself trying to find an audio problem during a recording session, your hard work certainly pays off.
