Audio Interface

An audio interface is very common equipment that you can find in many content creators, podcasters, or aspiring musicians. They are crucial for everyone working the audio in a computer because the machine doesn’t have professional connectors to bridge the connection. The audio interface’s job is to take the signal from your input, convert it, and send it to a DAW or monitor. You want one because you have an XLR or a quarter-inch input.

The input can be a condenser or dynamic microphones like SM7B, an electric guitar, or other electronic instruments with the same connector. If you are recording voice and already have Blue Yeti, there is no need to add an interface in the setup because the mic itself is already powered and recording directly to your computer. Besides analog to digital, the interface also works backward, converting digital information into an analog signal that we can hear from headphones or monitors.

When buying an interface, it is wise to consider what you need from the unit. The basics is matching the input and output you will be using. If there is only one microphone, a model with only an XLR or XLR combo will be sufficient, but if you use two mics or recording instruments, then we need something with more inputs. Additionally, check whether the interface is compatible with your computer operating system because some of them, especially the latest releases, will only be compatible with recent updates.

About Audient EVO 4 and Focusrite Solo

Depending on what you need from the interface, they can start from around $100 for the models with fewer features. Naturally, the cost will increase together with the number of bells and whistles in the unit. We also recommend getting one from well-known names to ensure quality and performance because we want the equipment to last as long as possible. If you already have the microphone, we recommend checking the gain range of the interface, especially if it is a dynamic model.

Dynamic microphones tend to be less sensitive and need a high gain setting to be audible without introducing much noise. Some people choose to add a cloud lifter, but it is more convenient to have a capable interface from the start. If you only use one microphone, the Audient EVO 4 and Focusrite Solo will be two exciting options to consider. The price point makes them ideal for many people as they are very affordable and proven to work very well.

They are also versatile if you play some music or are looking for an interface with the ability to work with an instrument. However, the Audient EVO 4 and Focusrite Solo are quite different because EVO 4 is a two-channel model. At the same time, Solo is a single channel, meaning if you will use two XLR/TRS inputs in the future, then Solo is out of the option. They provide some valuable features to increase value, but we think they are ideal for different users.

If you need two preamps, the EVO 4 is an ideal choice to make it straightforward. It also has a beginner-friendly feature that lets you set the gain automatically. But, if you want a cheaper option that works perfectly fine for a simple setup, the Solo costs less and already has all the basic features. If you don’t mind spending more, the EVO 4 with more bells and whistles is our favorite of the two. Read also: Audient EVO 4 Vs Audient iD4 here.

Audient EVO 4 and Focusrite Solo Design 

Fashion is a statement, and this is true with Scarlett interface. The interface series looks amazing on modern and traditional setups and is one of the best build quality among many similar models in the price range. The housing is metal, and all knobs/buttons are high-quality. The interface also provides dedicated control for each function, so you don’t need to switch to every mode available. It is a standard USB-C connector with minimal level information, only through the LED around its gain knobs.

The EVO 4 is far from the best build quality, but we think it is necessary to push the cost down. The interface is made of plastic and has a tiny flex when you press the housing. We like the matte finish, and it should be fine for a stationary setup. It has a brick design, and instead of on the side, the knob will be at the top. The EVO 4 also uses USB-C to power the unit, and both models come with the cable. Similar to Solo, this interface only has LED lights without proper level marking for information.

Audient EVO 4 and Focusrite Solo Specs

It is crucial to check the specs and match them with your equipment if you already have the microphone and headphones before buying an interface. One of the most important is a gain range because it affects what you can drive with the interface. The Audient EVO 4 and Focusrite Solo have a similar gain range of 58dB and 56dB. Famous microphone SM7B requires 60dB gain to work properly. We can boost the signal via software or add a cloud lifter to bring the gain down to a functional level.

In addition, it is necessary to see whether the headphone amp in Audient EVO 4 and Focusrite Solo is sufficient for your headphone. If you have regular models that work well with smartphones and compact devices, we think they will work excellent. But, if you have a hi-fi, professional headphone that usually has a high impedance, the amp may not be able to produce an adequate volume. Focusrite recommends its third-gen interface with a maximum impedance of 200 Ohms.

Audient doesn’t have a recommended headphone model, but it is likely the same as Solo. With any of these models, you may not be able to drive something higher than 200 Ohms properly. For example, the 250 Ohms models like Sennheiser HD58X sound quiet and thin even at a maxed gain.

Audient EVO 4 and Focusrite Solo Interface 

Next, let’s see the available inputs, outputs, and controls on Audient EVO 4 and Focusrite Solo. Starting with EVO 4, there are two microphone preamps with XLR combo jack and one line/instrument input. While visually you have three inputs, one of the microphones will mute when the instrument input is active. This interface has a quarter-inch headphone jack and a balanced output on the back. Similarly, the balanced output will be turned off when the headphone is active. The EVO 4 can adjust the mix level and output volume level.

On the other hand, Focusrite Solo only has one preamp and one strictly XLR connector; unlike the 2i2, it is not a combo jack. Solo has a line/instrument input with a dedicated gain knob; the LED around its gain knobs will turn red when clipping. The Solo provides monitoring through a quarter-inch headphone jack and a balanced output on the back. The interface can use both outputs simultaneously, but the volume knob is the same. Increasing the monitor level will also increase the headphone.

Audient EVO 4 and Focusrite Solo Features

The Audient EVO 4 and Focusrite Solo come with exciting features to help the application. The EVO 4 has a SmartGain function which is very helpful for new users who aren’t sure where to set the gain at. The feature takes all the guesswork and sets an automatic gain for your input. You can remember the setting later when reconnecting the input. It also has a loop-back feature on the software so we can record with background sound from the computer.

Scarlett also provides a loop-back feature, but sadly it is not available on the budget options like Solo and 2i2. The Solo has an Air button that mimics the original ISA 110 mic preamp, which is useful to improve your recording, especially for a voice like singing. The feature makes vocals more present and improves the sparks or makes it “airier.” It is also helpful for bright instruments like cymbals to add sparkle and sheen.

Audient EVO 4 Vs Focusrite Solo

Both Audient EVO 4 and Focusrite Solo are good options in the budget range. But, they are also quite different, and in general, EVO 4 offers more inputs and features. The interface has two XLR combos instead of just one XLR connector in Solo. It has a SmartGain feature to help new users set an ideal level for their microphone. The software includes a loop-back feature to let you route input from the computer on the headphone/monitor. However, the EVO 4 has a similar gain range and headphone amp.
