Best 2-Channel Audio Interfaces 2023

In the previous two decades, audio interfaces have advanced by leaps and bounds. They’ve gotten more competent, smaller, and less expensive, and the gap between consumer and professional interfaces has narrowed significantly.

Some of the best musicians, producers, and engineers use 2-channel audio interfaces to work on ideas and mixes from their hotel rooms or backstage during a tour in today’s truly mobile environment. Beginners are naturally drawn to these all-in-one recording solutions because of their low cost and fantastic features.

In this review, we’ll look at some of the best pro-level, small-format interfaces on the market. We’ll limit our list to those that start with two mic preamps, but because this is such a big market, the overall number of inputs, outputs, and other specifications will vary.

Lastly, the included Focusrite Control app enables you to adjust levels, monitor mixes, routing options, and more via your Mac, PC, or iOS device.


Solid State Logic SSL 2 USB Audio Interface - 24 bit/192 kHz, 2-in 2-out, with SSL Legacy 4K...
  • 2X Class-Leading Mic Preamps (130.5dB EIN / 62dB of Gain)
  • Pro-Studio Quality Neutrik Connectors and Alps pots
  • High Current Headphone Amp

A two-channel Solid State Logic audio interface for a reasonable price? Yes, absolutely! For over 40 years, SSL has produced some of the most known recording consoles, some of which cost more than your parents’ home! The SSL 2 introduces pro-grade preamps and outstanding 24-bit/192 kHz converters to the home studio at a price that even novices can afford.

The SSL2 audio interface has the same natural sound and high build quality that SSL is known for. The SSL2 offers great quality in a tiny form size, with two class-leading microphone/line/instrument inputs and 24-bit/192 kHz converters from industry-renowned producer AKM. This audio interface has Neutrik connectors and Alps pots and is housed in a robust, stylish enclosure.

Its ergonomically pleasing front panel design provides an intuitive workflow with easy-to-read metres and an ergonomically rewarding feel that will be welcomed in your home studio. A high-current headphone amp is also included in the SSL2 for precise monitoring.

The Legacy 4K function on the SSL2 offers the preamps two fundamental qualities of the 4000 series signal chain just by pressing a button, giving them the sound of the iconic 4000 series recording consoles. The first is a musical high-frequency EQ boost that pushes a vocal or instrument forward in the mix for a richer, more dimensional sound. The signal is then given a mild boost of harmonic distortion, which sweetens the sound and gives it personality.

The SSL2 comes with a comprehensive production pack that includes third-party software from Avid, Ableton, and Native Instruments, as well as over 1.5GBs of Loopcloud samples for those looking for an audio interface that “has it all.”

Overall, this is without a doubt one of the best audio interfaces on the market today, coming from one of the most coveted audio companies in history.

  • The full package for creating – All the software you need to record and build tracks, plus synths, effects, and more

Musicians, beatmakers, and performers that want to capture ideas, generate, or use high-quality audio in their live sets will love the Komplete Audio 2. The Native Instruments Komplete Audio 2 interface has a design with LEDs for two input ladder metres, USB connection, and 48 V phantom power on half of the top panel and a large output volume knob on the other.

It’s small and light, weighing only 360 grammes and measuring 140 mm x 52 mm x 112 mm. This audio interface has a single stereo headphone output and two 1/4′′ jack main outputs for connecting professional studio monitors and other devices. The main output level is controlled by the large knob on top, while the headphones have their own volume control on the front panel.

The Komplete Audio 2 additionally has two phantom-powered combo XLR/jack inputs that can be switched between instrument and line levels individually. The Komplete Audio 1 and 2 are both 2-in/4-out USB 2.0 boxes powered by the bus, with the only difference being the nature of the ins and outs. For the sake of simplicity, we’ll concentrate on Audio 2 in this article.

With this interface, you can record two mics at the same time, or bass and guitar, or a synth’s left and right outs, and so on. The delay is typical of a USB 2.0 interface, ranging from 7.55 milliseconds round trip at 44.1kHz with a 32-sample buffer to 51.8 milliseconds at 1024 samples.

RME Babyface Pro FS USB Audio Interface

RME Babyface Pro FS USB Audio Interface
  • 12 in/12 out USB Audio Interface with 24 total channels
  • 2 microphone preamps and 2 instrument preamps
  • Full SteadyClock FS circuit as in the ADI-2 Pro FS for lowest jitter and highest jitter immunity

The RME Babyface Pro FS is a bus-powered USB audio interface that is both powerful and portable. It has a tough, low-profile housing with a clean design and simple controls. Two digitally controlled microphone preamps provide reference-quality recording, while abundant analogue, digital, and MIDI connectivity makes integration with your studio simple. The Babyface Pro FS uses the same SteadyClock FS circuit as RME’s reference-quality ADI-2 Pro AD/DA converter, assuring ultra-stable clocking and a significant performance jump over its predecessor.

RME’s TotalMix FX engine provides a completely adjustable 288-channel mixer with 46-bit internal resolution, as well as latency-free processing including a 3-band EQ, low-cut filter, reverb, and echo. The remarkable capabilities of this state-of-the-art audio interface are rounded out with clear onboard metering. The RME Babyface Pro FS supports USB-C and includes a premium plug-in bundle as well as USB-2 and USB-C connections.

When you first see the Babyface Pro FS, you’ll be astounded by its incredible power and versatility. Its low-profile metal case has a very clean aesthetic to it, but it still gives you a lot of control over levels, sub-mixes, and gain structures. Two digitally controlled reference mic preamps, two balanced line outputs, line/instrument inputs, ADAT/SPDIF I/O, a MIDI port, and two headphone outputs are all included. Onboard metering is also included, as well as peak and RMS calculations. Best of all, the Babyface Pro FS accomplishes all of this while remaining simple and attractive on your desk.

The Babyface Pro FS, in addition to its improved SteadyClock FS circuit, boasts a slew of significant enhancements over its predecessor. The signal-to-noise ratio of its microphone preamps has improved from 112.2dB to 113.7dB, while the line/instrument inputs have improved from 114dB to 116.3dB. The THD of the line inputs was reduced by 8dB. The Babyface Pro FS uses the same ADI-2 Pro’s high-quality output op-amps. The THD of both headphones outputs has been improved by up to 10dB, and the 3.5mm headphones output power has been increased from 70mW to 90mW.

In addition, the impedance of the 3.5mm output was reduced from 2 to 0.1 ohms. A +19/+4dBu switch lowers the interface’s output level, enhancing signal-to-noise ratio for sensitive active monitors, avoiding overloads and distortion, and allowing you to keep TotalMix FX’s faders close to 0dB rather than at high attenuations. On the A/D side, you receive six samples less latency. And all of this was accomplished without increasing the power consumption of the audio interface!

Two updated Scarlett mic preamps, high-performance 24-bit/192kHz AD/DA converters, optimised preamp gain structure, reduced latency, and instrument inputs that can handle hot sources are all included in the third-generation Focusrite Scarlett 2i2.

To top it off, the mic preamps now have Focusrite’s Air mode, which adds a brighter, more open sound to your voice and instrument recordings by modelling the Air effect after the company’s iconic ISA console transformers.

This USB bus-powered interface has two mic/line/instrument inputs for recording and playback of up to two channels at the same time. All of this is made possible through headphones and monitor outputs that can be controlled independently. Focusrite announced support for iPad Pros with USB-C connectors as a direct response to its consumers. Simply connect your iPad Pro to the adapter and launch your music-making app. It doesn’t get any more straightforward than that!

The Scarlett 2i2 also has halo indicators that let you know when your recording signal is at its best. If the halo turns red, your signal is clipping, and you should reduce the gain. As the level rises to a suitable level, the halo will turn amber before turning green. This ensures that you’re always recording at the highest quality!

This interface is also perfect for mobile recording, and it comes with a software bundle that includes Ableton Live Lite and the Pro Tools First Focusrite Creative Pack, among other things. You’ll also get the Time and Tone Bundle from Softube, as well as the Focusrite Red Plug-In Suite and access to the Focusrite Plug-In Collective. As a result, the Scarlett is an excellent alternative for those seeking for their first interface.
