We have good news if you don’t know which preamp to choose for your studio. This article will show you the Top 12 Mic Preamps In 2023 For Your Vocals:
Many discussions are going on about whether a mic preamp is needed if many audio interfaces have built-in ones. That’s for you to decide, but one thing’s for sure: many professional recording studios still use this gear.
It simply helps to prepare the signal for the next stages of processing and can saturate it with harmonics. Before we get to the list, let’s review some other questions.
Do preamps reduce noise?
Some high-end preamps can produce less noise. But really, a lot depends on other factors. For example, what kind of microphone do you use? As far as we know, a dynamic microphone often produces more noise than a condenser microphone.
Also, the quality of the mic itself can affect this. So, pay attention to exactly what you record your source with.
Do preamps enhance sound quality & make difference?
Preamps can add saturation and coloration, but the quality of the audio largely depends on the performance itself or the instrument. Yes, expensive gear can make the sound a little more expressive. But what if it was recorded on a bad microphone?
These things are relative. Preamps are just one part of the big picture called audio production. Each component affects the overall quality.
As for the differences, each preamp sounds different. Sometimes this difference can be insignificant. In general, a lot depends on the level of professionalism of the person listening. If you have a trained ear for years, you will hear the difference, making it meaningful to you.
Top 12 Mic Preamps For Warm Vocals 2023
1. SPL Goldmike 9844
The Goldmike 9844 from SPL gives you a warm and clean sound for your vocals and other instruments.
If you are interested in audio equipment, you know about the German company SPL. These guys have been working since the 80s and provide high-class products that surprise with good build and excellent sound quality.
For example, look at their Vitalizer, which became a real hit with many producers and audio engineers.
But now we will talk about a two-channel tube preamp called the Goldmike 9844. So again, you get Class-A technology for each mono channel and, therefore, a corresponding sound.
But beyond that, many features set this piece of equipment apart from others of a similar kind.
- +72 dB of Preamplification
The dynamic range of this preamplifier is 111 dB, and the amount of preamplification is up to +72 dB. Your main tools in this task will be the two black knobs for each channel. Just find the right level, and you’re good to go.
- Phantom Power Button
You will find several additional features in the form of black buttons at the bottom for each channel. The first is 48V Phantom Power. So you can apply it if you are using condenser microphones.
- Low Cut Filter
You can easily apply the Low Cut Filter if you need to get rid of unnecessary information in the low frequencies. You will also find this button on the front panel. So the preamp will make a filter around 50 hertz with 12 dB per octave.
- Add Some FLAIR
Let’s say you feel that your signal lacks more presence in the high frequencies. In that case, Goldmike 9844 allows you to apply a FLAIR circuit, which will provide some bump just in this range. But, overall, it works incredibly well for voice.
- Reverse & PAD
Another great addition to this preamp is the Reverse and PAD functions. The first is phase reversal, which can help if you’re working with two similar sources simultaneously. The second is a signal reduction down to -15 dB.
Character & Sound:
SPL Goldmike 9844 provides a clear and expressive sound. It is ideal for vocals and acoustic instruments. And thanks to the FLAIR function, you can get even more clarity and presence, especially for the voice.
The Goldmike 9844 preamp is built with German precision and quality. It’s a beautiful studio tube unit that gives you a more expressive and clean signal at the recording stage.

2. Universal Audio 710 Twin-Finity
With Universal Audio’s 710 Twin-Finity, you get the best of both worlds of preamplification.
Imagine that you can use the transistors’ clarity and the tubes’ drive and even blend them. That’s exactly what the 710 Twin-Finity preamp from the famous American company Universal Audio is. So it’s a versatile solution to experiment and get the sound you want.
In general, it is a single-channel preamplifier that you can use both for voice and any other instruments. Its main feature is its two paths, one involving solid state technology and the other Class-A tube. And you can easily choose which one you prefer. Let’s now try to understand all the features in more detail.
- Blend Transistor With The Tube
The main feature here is the Blend knob, located in the center. You can get either 100% transistor preamplification or tube preamplification. What’s remarkable is that you can change this ratio in both directions. Just choose the sound that best suits your situation.
- Input & Output Control
You will also have two large knobs on either side of the front panel: the Input and Output knobs. So, for example, if you turn up the Input when using the tube path, you get the extra harmonics we all love so much about this technology.
- Detailed Metering
The preamp also has an analog VU Meter, which will allow you to monitor the performance of this piece of gear easily. On the right side, there is a switch for what it will show. For example, you can monitor Output or Drive, showing how you’re pushing the preamp stage.
- Mic or Line Modes
If you need to record voice or vocals, just set the appropriate switch on the front panel to Mic mode. If you are working with an instrument, set it to Line. The 710 Twin-Finity won’t limit you in these ways. As for the XLR ports you need, you’ll find them on the rear panel – Mic Input, Line Input, and Line Output.
- Low Cut & -15 dB PAD
Another cool feature is the ability to apply a -15 dB PAD. It will be helpful if you need to record the DI of an instrument with active electronics. There is also an option to use Low Cut, which will save you from the unnecessary rumble.
Character & Sound:
With the 710 Twin-Finity preamp, you get the opportunity to use two sounds at once. For example, the transistor will be unusually transparent, with a characteristic bite. As for the tube, it will sound warm with a big body. You can even get some distortion if you push the Input hard.
Universal Audio 710 Twin-Finity is an excellent preamp for experimenting with two different sounds. You get the ability to mix transistor and tube as well as quite a lot of additional features.
So this gear is a fantastic option for those who take music production and their studio seriously.

You will have a single gain knob, designed in the typical API style, which will allow you to add up to +65 dB. You can apply a -20 dB PAD if the signal is too high. By the way, you won’t find a separate output control here.
- Mic & Hi-Z In On The Front
There are two inputs on the front of this unit: one is Hi-Z In, where you can connect instruments, and the other is Mic In. A separate white Mic button activates the latter.
- Phantom Power and Polarity Switch
On top of that, you’ll have a Pol button for phase reversal and 48V to power up the condenser mics. The former is in yellow and the latter in red. Use them based on operational needs.
- LED-VU Meter
The API 512c is also equipped with a LED-VU meter to show the signal level accurately. These are small indicators in the upper right corner of the unit. The monitoring range varies from -12 to +18 decibels.
Character & Sound:
The API 512c preamp provides a warm and expressive sound. You can use it for any source like vocals, guitars, bass, drums, and other instruments. Plus, it doesn’t produce noise because it’s a -129dB low-noise preamp.
The 512c can be a good option if you want a premium preamp. This unit has been proven on many albums in top recording studios. Plus, it’s a 500-series unit, so that it won’t take up much space in your studio.
Among the disadvantages of this preamp is the lack of output control. In addition, it has no high-pass filter. And, of course, since it is the top hardware, its price is high – it’s almost a thousand dollars.
Manley Voxbox (Channel Strip With Preamp)
Manley Voxbox will serve you not only as a preamp but also as a first-class channel strip.
Now it’s time to look at another high-end unit, and it’s the Voxbox from Manley, a company that makes high-quality studio gear. Overall, it’s a single-channel tube preamp that includes an electro-optical compressor. But the presence of additional features here is incredible.
In addition to the preamp, you will have a compressor, de-esser, and EQ. So you can get a more or less mixed vocal track even at the recording stage. But this does not mean that Manley created the Voxbox exclusively for voice.
You can efficiently run other instruments through it. Let’s now take a closer look at the features.
- Preamp Stage
The first section in the circuit of this unit is the Preamp. You will find it on the left side of the front panel. Here you will have an Input and Gain control, with which you can tune negative feedback from 40 to 60 dB. In addition, there is Phase Reversal, Phantom Power, and a separate Instrument Input.
- Use Some Compression
The developers of Voxbox also implemented a Compressor here with a fixed ratio of 3:1. You will have five attack and release modes, from fast to slow, and a Threshold knob. In addition, there is a separate switch that you can use to put the compressor in Bypass mode.
- Simple De-Esser
As for De-Esser, it’s pretty straightforward here. You can apply it to the 3K, 6K, 9K, and 12K range or as a 10:1 limiter. And, of course, the Threshold knob will help you adjust it more accurately and determine the amount of de-essing.
- Pultec-Style EQ
Another great feature is the Pultec-style EQ, which you will find in the last section of this unit. In general, you will have three knobs, Low Peak, Mid Dip, and Hi Peak, which can boost up to +10 dB. In addition, you can take this equalizer and apply it separately, thanks to the EQ Out on the back panel.
- Detailed VU Meter
And, of course, the creators of Voxbox did not leave you without a VU Meter. Thanks to it, you can monitor the unit’s work pretty clearly. In addition, there are several measuring modes, including G-R, Line In, PreOut, EQ Out, and D-S.
Character & Sound:
The Manley Voxbox will provide silky and expressive-sounding vocals and a fat bass DI. You can experiment and apply it to other instruments, as this unit is quite versatile and gives you a lot of room for action.
It is top-of-the-line equipment that will be a great tool in your studio. The main advantage of the Voxbox is its versatility because, in addition to the preamp, you can also use compression, de-esser, and EQ. This box holds everything you need to process vocals and other instruments professionally.
The only disadvantage of this unit may be its enormous price, which is more than 4 thousand dollars. But that’s what you have to pay for equipment of this quality. Also, Voxbox has only one channel, which can also seem like a limitation.
As you can see, there is a whole bunch of different preamps that can be a great tool in your studio. However, they all have different sounds and price tags. In the end, we’ll offer some tips to make it easier for you to decide which gear to choose.
