Audio Interface and Mixer

In modern days computer is a very capable machine. The device is no longer only valuable for specific people and professions but for most of us who live and work using the technology. From students to office workers and artists use computers daily. A computer has a sound card built into the unit to allow users to listen to audio through a listening device like speakers or a microphone to record sound and communicate. The problem with the built-in sound card is that they are not always reliable.

You will need a better component to achieve better audio quality. While a headset with a built-in mic is highly convenient, they are not ideal for more serious purposes. An audio interface is a solution for users who want to connect an external microphone to their PC or laptop. You can also use a mixer as an interface as long as it has a USB connector. A mixer is a more capable equipment than an interface, but they are also more expensive.

A mixer is not very common in simple setups and is more prevalent for musical recording. The mixer has a preamp like most audio interfaces, so you can plug a condenser or dynamic microphone into it. What a mixer has but an interface doesn’t is an extensive set of inputs and outputs. They also have EQ parameters for each channel. A mixer is ideal if you have plenty of inputs, like five, for example, and is more convenient as we can tweak each channel separately. The higher models even have effects built into the equipment.

About Audient iD4 and Scarlett Solo 3rd Gen

On the other hand, an audio interface is ideal if you only use a microphone or an instrument. An audio interface is more straightforward and smaller, so it will fit easily in most desktop setups. The equipment also plugs and plays with your computer and preferred audio software. Users will need to connect the interface and ensure that the software can recognize the input. Many companies provide free software on their website that is compatible with their products.

Tips for selecting an interface are finding your budget and the amount of input/output you need. You can also buy one of the most popular models because they will work well. But, we highly recommend choosing according to your needs since not all of us have the same applications. For those who only use one or two inputs, compact models like Audient iD4 and Scarlett Solo 3rd Gen are two ideal options. They are reliable, affordable, and versatile.

However, they are not the same, especially in price point. The iD4 is not a new interface and is currently in its second iteration, while Solo is in its third model. The Audient iD4 is more expensive than Scarlett Solo, but the interface also offers more. We also think the iD4 has a better user interface because it is easy to see the level rather than just a single LED light that changes color. Additionally, if you somehow need two headphone jacks, the iD4 provides the feature.

Do these features make Audient iD4 a better choice than Scarlett Solo? It depends on whether you are interested in these bells and whistles because the price gap is relatively high. If you only need a reliable and affordable interface, the Scarlett Solo 3rd gen is a very nice option at this price point. Read also: Motu M2 Vs Audient iD14 here.

Audient iD4 and Scarlett Solo 3rd Gen Design

It is nice to have a well-built product while it doesn’t affect the performance of these audio interfaces. While Scarlett Solo is cheaper, this model uses all-metal housing. The 3rd Gen has a similar built quality to its predecessors, but the knobs feel better. Scarlett is an iconic interface because of the visual, which makes it stand out among similar equipment. The layout is straightforward and compact, with every button and knob having its functionality. The interface only comes with a USB-C cable.

On the other hand, the iD4 has a classic hi-fi look. The interface in our comparison today is the first model, and you can find the newer variant of MkII at around the same price point. Unlike Scarlett Solo, the layout is at the top but ergonomically very similar. Because this model is older, you will get a USB2 instead of type-C. Like Solo, the buttons and knobs are not flimsy, and the built quality is excellent.

Audient iD4 and Scarlett Solo 3rd Gen Interface

Let’s see what the Audient iD4 and Scarlett Solo 3rd Gen can offer, starting from the interface or layout. The Audient iD4 has one XLR combo input, balanced output, and USB power input at the back. The front panel is where you can find the DI port for your instrument and two headphone jacks; a quarter-inch and a 3.55mm jack that offer zero-latency monitoring. We have four knobs at the top to adjust the mic’s gain, DI gain, mix, and the largest is for volume.

There is a mute button to mute the speakers and an iD button to change its volume knob’s function. There are several LED lights to indicate phantom power and connection status. The Audient iD4 also has meters for both XLR and DI input which rarely exist in an audio interface. On the other hand, the Scarlett Solo 3rd Gen only has an XLR-type microphone input with separate line/instrument input. Both inputs have their gain knob, but only the XLR has phantom power.

The LED light around these gain knobs will turn green in a healthy signal, yellow when almost clipping, and red when clipping. The largest knob is for the monitor’s volume, headphones, and the balanced speakers on the back. The Solo only has a quarter-inch headphone jack that also offers zero-latency monitoring. We found a pair of speaker’s output and USB-C power ports on the rear panel.

Audient iD4 and Scarlett Solo 3rd Gen Specs

Next, let’s see the general specs of Audient iD4 and Scarlett Solo 3rd Gen because there are some notable differences. The frequency response of Solo, according to Focusrite, is 20Hz to 20kHz for all inputs. The gain range for its XLR input is 56dB which is very common for an interface in this price range. The interface also has a very high dynamic range of 111dbA and a very low noise of -128dbU. The maximum sample rate we can record is 192kHz and a bit depth of 24-bit.

The Audient iD4 frequency range is 10Hz to 40kHz and a gain range of 58dB. This interface has an even higher dynamic range of 120dbA and a low noise floor of -126dbU. As for the sample rate, this interface can record up to 96kHz and a bit depth of 24-bit.

Audient iD4 and Scarlett Solo 3rd Gen Performance 

The Audient iD4 and Scarlett Solo 3rd Gen perform well for condenser and dynamic microphones. You can connect almost any microphone with the proper connector to these interfaces. They also seem to drive SM7B at a usable level even though we have to crank the gain at almost 100%. But you can still use the infamous gain-hungry microphone without cloud lifter, and we think they sound pretty good. The noise level is also ultra-low and about the same.

Their headphone output also produces a decent quality but is noticeably different. The frequency response of Solo is flat for headphones with low to mid impedance. But, the distortion when using low impedance headphones is noticeably higher than iD4. On the other hand, iD4 is best for medium to high impedance headphones, and it is also much better against distortion regardless of the impedance.

Audient iD4 and Scarlett Solo 3rd Gen Features

Lastly, we want to mention some added features. The iD4 has an ID button which changes the function of its main knob as controller on the software. The mute button is also useful for muting the speakers, and the LED status is a great feature to monitor your input levels. As for the Scarlett Solo, this interface has an Air button that simulates the original ISA 110 preamp. The feature gives your vocal an airier sound or more open, light, and detailed.

Audient iD4 Vs Scarlett Solo 3rd Gen

Both Audient iD4 and Scarlett Solo 3rd Gen are good interfaces, but they are also different. The specs are not identical, but both are very similar from the gain range to the noise level. You can plug a gain-hungry mic and still make it useful without noticeable noise at a very high gain setting. However, the headphone amp is different because iD4 has much better distortion performance with low or high impedance headphones. Still, both models will benefit from using medium to high impedance headphones.
