Best Solid-State Preamplifiers for Vocals

Solid-state preamps are designed and constructed using passive components such as resistors, capacitors, diodes, transistors and integrated circuits also known as chips.

These preamps are known for their transparency and crisp punch, which allows you to create higher gains without necessarily causing any distortion.

Next, we take a look at some of the best solid-state preamplifiers for vocals available in the market today.

Grace Design M101 Single Channel Microphone Preamplifier

When it comes to recording equipment there is always a gap between affordability and quality. Manufacturers like Grace Designed based in Boulder Colorado in the U.S.A has designed a preamp that reduces that gap.

The M101 is one of the best mic preamps for vocals that delivers high-quality audio and is under $1000. This model is the redesign of the highly popular and successful model 101 preamp launched by the same company years earlier. 

Built Using Precision Components

The signal path of the M101 uses high precision resistors made of metal film with tolerances of 0.5% or less.

It also uses a design topology called trans-impedance amplifier circuitry in which no impedance matching transformer and no electrolytic capacitors are used because they can cause nonlinearities in the signal path.

Because of these design considerations and many others not mentioned here due to their highly technical nature, the Grace Design M101 provides the highest levels of signal clarity and naturality at very low noise, even when using ribbon microphones.

Features

• It has one channel that is balanced for connecting a microphone and a high impedance channel for instruments such as guitar, bass, drum machine, etc.
• Thanks to its design topology the signal path in the M101 is unaltered with the use of surface mount precision resistors, transformerless impedance matching, and no electrolytic capacitors to keep linearity.
• This device also has a rotary gain-potentiometer with 12 positions.
• Line drivers with a high output of performance.
• The high pass filter has a 12 dB/octave slope at 75 Hz.
• Wide gain range structure from 10-75dB.
• This device features a ribbon microphone mode switch with an extra 10dB gain and a safety function that turns off phantom power to protect the mic from being damaged.
• Heightened RFI suppression.
• 3 Output Connectors- XLR Balanced, ¼” TS Balanced and ¼” TRS Balanced.
• LED Indicators.
• Half rack wide, two units would fit side to side in a 19” rack space.

Pros

• Rugged case construction and sound quality that is world-class.
• Superlative response is very high-end.
• It is quite affordable for being a high-end single-channel mic preamp.
• It is easy to use and set up.

• XLR Input and outputs are gold plated.
• Precision gain potentiometer.

Cons

• No polarity reverse switch.
• No phantom power indicator light.
• The power adapter is not of the best quality.

Professional sounding recordings start with a good microphone with the correct sonic characteristics, but it doesn’t matter how great your microphone is, if your preamp is not excellent, the captured sound will be dull and unnatural.

Sound engineers consider the M101 as one of the best solid-state preamplifiers available in the market at a price that is much less than the excellent sound quality it delivers.

With this preamp designed for vocals and instruments, you will be able to bring out all the subtle details that the microphone captures in a natural, crisp way.

Although this preamp may lack some of the features that higher-end preamps can offer, it is undoubtedly a great choice at this price range and can even give considerable competition to some devices that cost three to four times more.

AEA TRP2 Ribbon Preamp

There are many options to choose from when selecting a mic preamp. Although all preamps are designed to have one thing in common, to amplify low-level signals, they are not all created equal.

An example is the AEA TRP2. This mic preamp was explicitly designed to be used with ribbon mics.

Ribbon mics are a type of microphones built using a thin aluminum transducer called ribbon.

When sound waves hit the ribbon material, it vibrates. These vibrations create variations in voltage. This voltage is the soundwaves converted into an electrical signal.

Ribbon mics are known to produce the most natural and warm sound, delivering a very smooth mid-range response, which is great if you’ve been struggling to find a mic that captures your sound exactly the way you hear it.

If you are interested in checking out the best ribbon mics for recording vocals, click the link.

Designed to Enhance the Sound of Ribbon Mics

The problem with ribbon mics is that they need a lot of gain to increase the signal to a point where it can be used in the audio chain.

Increasing the gain too much creates problems because any noise in the signal will also be amplified.

Another problem is finding a preamp with a high enough impedance to work with a ribbon mic. In simple terms, when it comes to input impedance, the bigger, the better.

When AEA designed the TRP2, three key factors were not negotiable. The preamp had to have very low noise, high gain, and high input impedance.

You will get these three features with the AEA TRP2. Keep in mind that it’s highly recommended to use this preamp with ribbon mics because it is specifically designed for them.

But you can also use it with dynamic and condensers as well, thanks to its switchable +48V phantom power.

Features

• It delivers an unprecedented +85 dB of clean, quiet gain on each of the two channels.
• The design is optimized for all types of microphones, but it’s perfect when used with ribbon and dynamic mics.
• With the TRP2, you’ll get an extremely flat and wide frequency response making it the perfect preamp for recording accurate, high-fidelity vocals.
• Suppose you plan to use this preamp only with ribbon mics and are concerned about hurting passive ribbons due to accidentally turning the phantom power on. In that case, this device comes with a phantom power kill switch located inside that you can easily deactivate, preventing the phantom power from ever turning on.
• Switchable low pass filter with a cut-off frequency set at 100 Hz. Perfect for helping to decrease the proximity effect in some mics.
• Super high input impedance set at 63,000 Ohms. Remember that having a high input impedance is a plus as it helps in getting a better sound because the preamp will not limit the lows, highs, and transients of your passive microphones.

This is How It Sounds

The AEA TRP2 was designed from scratch to offer low noise, high gain, and high input impedance. Its flat frequency response will deliver excellent results when recording vocals.

If you decide to use a ribbon mic, you’ll be amazed at the rich, natural sound that this preamp can bring out from your microphones.

Warm Audio WA-412, 4-Channel Microphone Preamplifier

The American Audio WA-412 is a fully discrete preamp designed and built using classic electronic components such as resistors, capacitors, transistors, and op-amps instead of modern integrated circuits positioning it as one of the best mic preamps for vocals and instruments.

It was originally developed for large format consoles used in professional recording studios and live stages.

Vintage Sound that Only Classic American Consoles Can Produce

This style of preamp is often referred to as “the sound of Rock n’ Roll” for its BIG punchy low and mid-end, and smooth clear open top end.

With the help of the WA-412, you can get the qualities of such vintage preamps along with direct input (DI) packs for instruments.

With this preamp, Warm Audio has been able to decrease the gap of price to performance ratio of pro audio preamps.

Traditional Design Topology and Components to Deliver the Best Classic Sound

The WA-412 continues the traditional component topology of transformer coupling on the inputs and outputs using premium transformers that are made by high-end transformer manufacturer Altran in the U.S.A.

Warm Audio worked closely with Altran to design unique transformers that extend the low-frequency response of these classic preamps by using a vintage winding technique that produces a very distinct smooth BIG character.

A key feature of this preamp is that each channel utilizes a fully discrete socketed 6-pin opamp that can be swapped with other op-amps.

What this means is that if you want to change the tone or gain architecture, just change the op-amp with another one that has the same electrical characteristics and your sound will be different.

Op-amps are designed to offer high headroom and low distortion characteristics.

Features

• The WA-412 is designed to produce bold, punchy sonics mimicking classic large-format American consoles.
• It has a tone switch input impedance that shifts the impedance from 150 ohms to 600 ohms. Using this feature with dynamic or ribbon microphones will give a different tone when changing the impedances in both the mic and HI-Z inputs.
• It includes a polarity switch for inverting the phase of the signal giving a distinct sonic characteristic.
• This device has a gain of 65dB which allows handling low-level signals with ease.
• It has a pad switch with 20dB decrease, which is capable of handling extremely high SPL for both instruments and mic inputs.
• and finally, we have a switch for engaging the high Z input which is the quarter-inch direct input here on the front panel on the back panel we have both balanced XLR as well as balanced quarter-inch outputs per channel each channel
• Features a seven-stage led meter to keep track of your levels.
• Every channel has a socketed X520 discrete op-amp that can be user-swapped with almost any discrete op-amp that has 6 pins.
• XLR direct-injection active instrument ¼” microphone inputs.
• TRS and XLR transformer-balanced outputs.
• It offers switchable +48 VDC phantom power per channel.
• A grounded IEC-3pin power cable completes this device’s internal power supply.

Testing the Warm Audio WA-412

Pros

• With the WA-412 you’ll get smooth sound.
• For optimum sound quality, each channel has an input gain control as well as an output trim control that allows you to set how hard you’re driving the input versus the signal that you’re sending out into your interface or analog to digital converters.
• It is ideal for condenser, dynamic, and ribbon microphones providing a classic warm fuller sound.
• This device is very well designed.

Cons

• There is no ribbon button to disable phantom power, this means that the user needs to be very careful not to connect a ribbon microphone if the phantom is enabled because it will damage it immediately.
• It doesn’t look as nice as other preamps, the all-metal chassis looks very classic, some people might not like that.

The WA-412 is an awesome choice for a vocal preamp because it is designed with dedicated circuit boards for every channel along with transformers made by Altran.

With this preamp you’ll get punchy, bold sounds that mimic classic American large-format recording consoles.

PreSonus BlueTube DP V2 2-channel Mic/Instrument Tube Preamp

The PreSonus BlueTube DP V2 is a hybrid preamp that has two stages, the solid-state stage, and the tube stage.

If the solid-state is selected the resulting sound is clean and quiet nothing different than the result you would get from a regular solid-state preamp.

The solid-state stage was designed by Presonus to provide low noise, flat frequency response, and low harmonic distortion.

If the Tube drive option is selected, the tube stage kicks in providing different sonic characteristics depending on how hard you drive the gain.

The overall sound using the tube stage is thicker and warmer but keeping the clarity and crispiness of the high frequencies.

By adjusting the gain, you can get a more saturated sound without too much roughness in the highs. This setup would be great for rappers using a condenser microphone because the sound would be more powerful giving you the right timbre for the songs.

The setup can be also useful for guitar, bass, and any other acoustic instruments where a saturated semi distorted sound is required yet keeping it clear in mid and high frequencies. 

The BlueTube DP V2 is a dual-channel that can be used as a mic/instrument preamp, or as a direct input for instruments.

The tube used on this preamp is the 12AX7 high voltage tube circuit which is responsible for the range of clean to pleasingly distorted sounds that this device can produce.

The DP V2 is a dependable preamp for vocals and instruments, that can help you with your recordings or live performances.
