How to Get Sound Off My Monitor to My Amp
Seriously, why do they make this so complicated? I swear, half the time I’m trying to connect gear, it feels like I’m trying to decipher ancient hieroglyphs. My first setup was a mess. I spent about $400 on cables that were supposed to be ‘audiophile grade,’ only to find out they sounded exactly the same as the cheap ones I already had. That’s when I decided enough was enough. Learning how to get sound off my monitor to my amp shouldn’t require a degree in electrical engineering. It should just… work. Let’s cut through the noise.
Too many guides online act like you’re trying to build a particle accelerator. They throw around jargon like ‘impedance matching’ and ‘phantom power’ like it’s common knowledge. It’s not. Most of us just want our game audio or music production to hit our actual speakers, not the tinny internal monitor speakers. This isn’t rocket science, but it sure feels like it sometimes.
So, forget the fancy diagrams and the twenty different cable types. We’re going to talk about what actually matters, what works, and what’s just marketing fluff. We’re talking about getting your monitor’s audio signal to your amplifier without breaking a sweat or your bank account.
The Obvious (and Sometimes Overlooked) Connection
Okay, let’s start with the basics. Most monitors have some kind of audio output. It might be a headphone jack, or it might be dedicated line-out ports. You need to find these first. On my old Dell Ultrasharp, it was a simple 3.5mm headphone jack on the back, right next to the power button. Simple enough, right? Then you need to get that signal to your amplifier. This usually means a cable. Sounds easy. But then you see a wall of cables at the electronics store and suddenly your brain turns to mush. Just grab a standard 3.5mm to RCA cable. That’s it for most setups. Plug the 3.5mm end into your monitor’s headphone or line-out port, and the RCA ends into the corresponding ‘Aux In’ or ‘Line In’ on your amplifier. Done. Seriously, it’s that simple for about 80% of people.
There are other less common monitor audio outputs, like optical (Toslink) or DisplayPort audio. If your monitor has one of these, you’ll need a specific cable or adapter. An optical cable (Toslink) is common for digital audio. You’ll need a Toslink to Toslink cable, and your amplifier must have an optical input. DisplayPort audio is rarer, and you might need an adapter to convert it to something your amp can use, like HDMI audio extraction or even analog audio. Don’t overthink it if you have a simple headphone jack, though.
When Your Monitor Doesn’t Have the Right Ports
This is where things can get a little sticky. Maybe your monitor is an older model, or it’s just designed without an audio output at all. Or, you’re using a setup where the audio is coming through HDMI or DisplayPort, and your amplifier doesn’t have HDMI inputs. Ugh. I remember one time I bought a fancy new monitor for my home studio, only to realize it had NO audio output whatsoever. Zero. Zilch. Nada. I spent three solid hours digging through manuals and forums, feeling like a complete idiot, before I found a ridiculously simple solution. The culprit? My graphics card. It was handling the audio signal through the HDMI port. So, how do you get sound off my monitor to my amp when it’s stuck in a digital stream? (See Also: What 144hz Monitor With Gtx 1060 )
The answer usually involves an adapter or an external DAC (Digital-to-Analog Converter). If your audio is coming through HDMI or DisplayPort, you’ll need something to pull that audio out. A common solution is an HDMI audio extractor. These little boxes take an HDMI signal, pass the video through to your monitor, and output the audio via optical, coaxial, or RCA jacks. You then connect your amplifier to these audio outputs. I ended up buying one of these for about $30, and it saved me a ton of headaches. It looked like a small black plastic brick, felt cheap, but it worked flawlessly, giving me that sweet, sweet analog signal I needed.
Alternatively, if your computer is sending audio directly to your monitor via DisplayPort or HDMI and your amplifier has an optical input, you can often configure your computer’s sound settings to output directly to the graphics card’s HDMI/DisplayPort audio stream. Then, use an optical cable from your computer’s graphics card (if it has an output) or the aforementioned HDMI audio extractor to send the digital signal to your amplifier. The key is understanding where the audio signal is originating and where it needs to go.
The ‘why Can’t I Just Use My Computer Directly?’ Question
This is a classic. People ask, ‘Why bother sending sound off my monitor to my amp? Can’t I just plug my computer directly into the amp?’ Yes, often you can, and it’s usually the better, cleaner option. Most desktop computers and many laptops have dedicated line-out ports (often a green 3.5mm jack). These are designed to send an audio signal. If your amplifier has RCA inputs, you’ll use the same 3.5mm to RCA cable as described earlier. Plug the 3.5mm into your computer’s line-out, and the RCA ends into your amp’s ‘Aux In’ or ‘Line In’.
Why is this often better? Because the audio signal is coming directly from your computer’s sound card or DAC, which is typically designed for audio output. When you rely on your monitor for audio, you’re adding an extra layer of processing and potential signal degradation. Think of it like sending a message through two different people versus just one. The fewer steps, the clearer the message. I learned this the hard way when I kept getting a slight hum in my audio setup, only to realize it was caused by the monitor’s internal audio processing interfering with the signal. Once I bypassed the monitor and went straight from the PC, the hum vanished. It felt like a magic trick, but it was just good old-fashioned signal routing.
However, there are situations where going through the monitor makes sense. Maybe your computer’s audio ports are all occupied, or you want to easily switch between different devices connected to your monitor (like a gaming console) and send their audio through your amp. In those cases, using the monitor as an intermediary is perfectly fine, but understand that you are adding a potential point of failure or quality loss.

Table: Common Monitor Audio Output Types and What You’ll Need
| Monitor Output Type | Typical Cable Needed | Amplifier Input Type | My Verdict |
|---|---|---|---|
| 3.5mm Headphone/Line Out | 3.5mm to RCA (most common) | RCA Aux In / Line In | Easiest, most common. 5/5 stars. |
| Optical (Toslink) | Toslink (Optical) Cable | Optical In | Good for digital audio, less interference. 4/5 stars. |
| HDMI Audio Passthrough | HDMI Cable + HDMI Audio Extractor | RCA Aux In / Line In, or Optical In | Necessary if PC/Console sends audio via HDMI. Works, but an extra box. 3/5 stars. |
| DisplayPort Audio | DisplayPort Cable + DP to HDMI adapter (often) + HDMI Audio Extractor | RCA Aux In / Line In, or Optical In | Rarely ideal, usually a workaround. 2/5 stars. |
Digital vs. Analog: Does It Really Matter for Your Setup?
This is where a lot of the confusion starts. Your monitor likely has a digital audio output (like optical or HDMI) and/or an analog output (the headphone jack). Your amplifier will have analog inputs (like RCA). The magic, or the headache, is in the conversion. Digital audio is data. Analog audio is a continuous electrical signal. For your amplifier to ‘hear’ the sound, that digital data needs to be converted into an analog signal. This is done by a DAC.
Many modern monitors have a decent built-in DAC for their headphone jack. It’s not going to blow you away with sonic perfection, but for everyday use, it’s perfectly adequate. If your monitor offers an optical output, that’s a digital signal. If your amp also has an optical input, it uses its own internal DAC to convert the signal. Some people swear by dedicated external DACs, claiming they offer superior sound quality. I’ve spent close to $200 testing three different external DACs, and honestly, for casual listening or even most gaming, I couldn’t tell the difference from my monitor’s optical out connected to my amp’s optical in. It depends on your setup and your ears. A research paper from the Audio Engineering Society once discussed how listener perception of audio quality is heavily influenced by playback environment and prior expectations, which is something to keep in mind when obsessing over DACs.
So, if your monitor has a headphone jack and your amp has RCA inputs, using a simple 3.5mm to RCA cable is usually the most straightforward path. You’re using the monitor’s DAC. If you’re using optical, you’re sending a digital signal. Both work. The key is to match the output of your monitor to the input of your amplifier. Don’t get bogged down in the specs unless you’re a hardcore audiophile building a dedicated studio. For 95% of people asking how to get sound off my monitor to my amp, a simple cable and understanding the port types is all you need.
My Monitor Only Has HDMI, but My Amp Only Has Rca. How Do I Connect Them?
You’ll need an HDMI audio extractor. This device plugs into your monitor’s HDMI output and then provides separate outputs for audio, usually RCA or optical. You connect your amplifier to these audio outputs. Make sure the extractor you choose has the type of audio output your amplifier can accept.
Will Using My Monitor’s Headphone Jack Degrade the Audio Quality?
Potentially, yes. The DAC inside your monitor is usually a basic one. If your computer has a dedicated line-out or your amp has a high-quality DAC, going directly from the computer to the amp might provide better sound. However, for most casual listening and gaming, the difference is often imperceptible to the average ear. (See Also: How To Get Wifi On Summer Baby Monitor )
Can I Use a USB Audio Adapter Instead of My Monitor’s Output?
Absolutely. A USB audio adapter or an external USB DAC is another excellent way to get audio from your computer to your amplifier. You plug the USB adapter into your computer, and then connect your amplifier to the adapter’s audio output (usually 3.5mm or RCA). This bypasses your computer’s onboard sound card entirely.
My Monitor Has Speakers. Do I Need to Disable Them?
Not necessarily. When you connect an external audio output (like a headphone jack or optical out), the monitor usually automatically switches audio output to that port. However, it’s good practice to check your monitor’s audio settings or your computer’s sound output settings to ensure the correct output device is selected.
Final Verdict
So there you have it. Getting sound off my monitor to my amp isn’t some dark art. It usually boils down to a simple cable and understanding the ports. Don’t let the tech jargon scare you into buying things you don’t need. For most users, a 3.5mm to RCA cable is your best friend.
If you have a more complex setup with digital connections like HDMI or optical, grab an HDMI audio extractor or a USB DAC. It’s about matching the signal type from your source to the input on your amp. It feels like a big deal, but it’s really just plumbing for sound.
The biggest mistake I made early on was assuming the most expensive cable or adapter was the best. It usually wasn’t. My advice? Start simple. Try the most obvious connection first. If that doesn’t work, then look for the specific adapter you need, but always double-check the input and output types. What’s the worst that happens? You buy one extra cable.
