What Cables Do You Need For Studio Monitors? (7 Cable Types Explained)

Studio monitors can come with a variety of connections for both inputs and outputs. For example, my studio monitors come specifically with a combination of an XLR and TRS jack input.

I’ve been asked what cables you need for studio monitors, since some studio monitors have an abundance of connection points (but not all of these cables are necessary). It all depends on what you are looking to do and how you are looking to connect your monitors.

Your studio monitors will need two XLR or TRS jack cables (one for each monitor). If you have active studio monitors, you will usually need a 3-pin power cable. For certain studio monitors, you might also need other cables, such as RCA cables, auxiliary cables, optical digital cables, and speaker wire.

In this article, you will learn the basics of every cable you might need for your studio monitors, how each one works, and the best uses for each one. You will also find a review and recommendation for each type of cable.

What Cables Do You Need For Studio Monitors?

Depending on the studio monitors you have, you will need a certain set of cables. For example, you will need power cables, cables to send input signals to your studio monitors, and cables that will send output signals from your studio monitors.

studio monitors
The cables you will need for your studio monitors varies, but you will always need power cables and input/output cables as well.

There are many different types of cables, and it can seem overwhelming because different instruments and audio devices might use different cables. Don’t worry though – we’ll sort out the confusion as we go along.

You may not need all of these cables, but it is nice to know what they all do. Your setup will determine which cables you need, since studio monitors will have different inputs and outputs depending on how they are built.

The main thing to keep in mind is what devices you have and what you need them to do.

Let’s start with power cables.

Power Cables (Kettle Cords)

If you are purchasing a pair of active studio monitors (monitors that have a built-in powered amplifier), then they will most probably already come with these cables. Usually, the power cables that come with studio monitors are your 3 pin kettle cord cables.

On the end that needs to be plugged into a socket, the attachment could vary. If the attachment that comes at the end of the power cord is not to your satisfaction, you can either:

  • replace it with a little DIY and put on a new end attachment, or
  • purchase new cables (you will need one cable for each monitor)

One thing to note (and I do this myself) is to replace the ends of the power cables with surge protection plugs. That way, if there is a power surge or lightning storm, I feel safe and reassured that my monitors won’t blow.

Use a surge protector to keep your studio monitors and other audio equipment safe from power surges or lightning storms.

(If this happens, you can find out how to check if your studio monitors are blown here).

You can also get some surge protection plugs that guarantee protection and give you a warranty on the devices connected to it.

Analog Cables & Digital Cables

Depending on your studio monitors, they will come with either analog connections or digital connections. For the most part, studio monitors usually come with analog connections (such as XLR and jack connections).

Analog cables deliver the audio signal by sending it through an electrical current. Sometimes, you can get noise and interference from these cables.

rca cable
Analog and digital cables send an audio signal, either by electrical current or by a binary code.

However, you there are workarounds that come in the form of balanced cables (more on that in the next section).

Digital cables (such as optical audio cables) send your audio signal along the cable via binary code. This is great because then there is no chance for interference from an electrical current or any other electrical device.

The table below summarizes the two types of cables and how they work.

Let’s look over analog cables used for your studio monitors and then optical cables.

Balanced Cables

For the most part, the inputs and outputs on your studio monitors will be balanced. So, to utilize these ins and outs properly, you will need the correct balanced cables.

Balanced cables are cables that reduce and even remove noise and interference. The most common types of balanced cables are XLR and TRS jack cables, which we will discuss further below.

xlr cable
XLR is one type of balanced cable.

All you need to know is that balanced cables are the best cables to use because of their specific design in reducing noise and interference. For the most part, you will always want to use balanced cables.

If you can’t use a balanced cable, you should try to convert the signal to a balanced signal.

XLR Cables

More than likely, your studio monitors will come with XLR inputs. These inputs will be your audio signal that the monitors receive from any other device, and they will play the audio through the monitors. Depending on your monitors, you will have either one input or multiple XLR inputs.

XLR cables are the best type of analog cables you can use for your studio monitors. They are balanced cables and can run up to 100 feet without any noise or interference.

xlr cable
XLR cables are a balanced analog cable. They can run up to 100 feet without noise or interference.

This performance is due to the design of an XLR cable. In short, you have two audio signals running through the cable, with one signal reversed in polarity.

In this way, the cable can effectively reverse the polarity at the end of the cable. This cancels out any noise and interference.

(If you think your XLR cables might be bad, read this article to find out how to check for sure).

Jack Cables (TRS)

There are two types of jack cables:

  • TS (Tip-Sleeve), which is unbalanced.
  • TRS (Tip-Ring-Sleeve), which is balanced.

Unbalanced jack cables (TS cables) are used for instruments (such as guitar and bass). TS cables are mono cables, sending one signal across the cable.

TS cable
TS (Tip-Sleeve) cables are unbalanced jack cables.

These types of cables (TS cables) usually do not have a connection point on your monitors, since these cables are used for instruments. As such, you will plug your instrument into an amp and then have it “miced up.”

Then, that balanced microphone signal will go through to your other audio devices, and then those devices will send a balanced signal to your monitors. Furthermore, that balanced signal being sent to your monitors if it is via a jack cable it will be via a TRS jack cable.

Balanced jack cables (TRS cables) are for stereo, and they are the balanced version of the TS jack cables. Make sure you do not get confused between the two. They do look similar, but the TRS jack cable has an extra line and section which is situated on the connection point.

trs cable
TRS (Tip-Ring-Sleeve) are balanced jack cables.

TRS jack cables, which are balanced, will also be used as input signals on your studio monitors if they do not have an XLR option. Usually, depending on your studio monitors, you will have a combination input connection that consists of both an XLR and a TRS jack input.

Unbalanced Cables

You might have some unbalanced inputs or outputs depending on your studio monitors and what type of connections they have. However, the main input and output connections on your studio monitors will be balanced for the most part.

Studio monitors will only have unbalanced connections to plug in certain audio devices, including:

  • RCA outputs from a mixer (mixing desk)
  • CD player
  • record player
  • cell phone
  • PC
  • laptop
Studio monitors have an unbalanced connection to laptops, PC’s, and some other devices.

The possibilities are only limited to the device and the connection you have on your studio monitors. Just remember unbalanced cables are prone to having some degree of noise and interference.

That does not mean they will sound horrible, or there will be a tone of noise. It just means that these cables are more susceptible to noise and interference.

Auxiliary Cables

Some studio monitors will come with auxiliary inputs. Auxiliary inputs could be RCA connections (which we will discuss under the next heading) or they could be a mini-jack connection.

Depending on your studio monitors, these will also be used for inputs. So, you could plug your CD player, cell phone, or any other device that sends audio signals via auxiliary cables.

cd player
You can use an auxiliary cable to plug a CD player into your studio monitors.

Hence, you could stream Spotify from your phone into your studio monitors if you wanted to do so.

RCA Cables

RCA cables are the “old” version of audio cables (in addition to your standard-issue speaker wires). You can tell an RCA cable straight away from their unique white and red connections.

rca cable
RCA cables have white and red connections, and are used to plug record players, CD players, cellphones, etc. into your studio monitors.

Again, RCA cables will be used as either input, most likely into your studio monitors. Hence you could again plug any form of an audio device such as a record player, cd player, cellphones, etc., into your monitors so they could play the audio for you.

RCA cables are unbalanced cables, so be sure to check out your other input options before using them. It’s always better to use balanced signals where possible.

Standard Speaker Wire

In some cases, your studio monitors may come with the “old” inputs where you have to strip some audio cable wire and then insert them into the monitors where they are held in place via a clip.

If you think about your home theater systems or bookshelf speakers, you will understand the type of connection I am talking about.

bookshelf speakers
Bookshelf speakers or home theater systems have standard speaker wires.

Standard speaker wires are cheap, unbalanced, and these connections will usually only be found on entry-level monitors.

Optical Digital Cables

An optical digital cable input could also be part of your studio monitors, depending on the quality of the monitors you have. Optical cables support ADAT and S/PDIF audio signals.

ADAT signals usually carry 8 channels of audio at 48khz and 4 channels at 96khz. S/PDIF carries only two channels of audio.

optical digital cable
Optical digital cables support ADAT and S/PDIF audio signals.

These connections are great and have no interference. They are used for a multitude of applications in the studio, which include sending 8 audio signals from a mic preamp to an audio interface and then sending out a stereo mix from your audio interface to your monitors.

We now know that there are actually quite a few cables that you could use for your studio monitors. However, not all of them are necessary.

studio monitors
There are quite a few cables that you might need for your studio monitors, but you probably won’t use every type that we mentioned in this article.

The most important cables you would need are:

  • cables to power your studio monitors (if they are active monitors), and
  • audio cables for your main inputs (these cables will send the audio signal to your monitors, so they play the audio back).

In most cases, you will just need a normal power cable with 3 pins and then either an XLR or TRS jack cable (2 of them, one for each studio monitor).

The table below summarizes the types of balanced and unbalanced cables for quick reference.

This table summarizes
various types of cables
and whether they are
balanced or unbalanced.

Depending on your studio monitors and any other audio devices you may have and would like to connect to your monitors, you would then have to see if your monitors support that connection and purchase the appropriate cable.

Be sure you know how to route your studio monitors to the devices you are looking to connect. Don’t just go buy every cable that can plug into your studio monitors, since you may not need all of them.

Lastly, if you are looking at purchasing a pair of studio monitors, be sure to check out our recommended gear section here, where I go over the top 15 studio monitors under the categories of budget, mid-range, and high-end studio monitors.

If you want your studio monitor to last a little longer, consider turning it off when not in use (you can learn more here).
