So you want a setup for putting together demos but you need more inputs? To tackle this problem, we’re looking at some of the best multichannel audio interfaces that provide you with the features and expandability to take on recording projects in almost any genre.

Whether you’re working with a mixing desk, a patch bay, or simply running multiple mics and instruments directly into the interface, having multiple channels gives you plenty of creative flexibility for different workflows and configurations.

Choosing the best multichannel audio interfaces

Multichannel interfaces are not only a considerable investment, but they also involve connecting with a wide range of equipment. This makes it important to select something future-proof, no matter what end of the market you’re shopping in.

Compatibility with current and future versions of your OS and DAW is essential, and you may even want to expand your interface with additional inputs at a later stage.

For this purpose, we’ll be looking at various options that are rack-mountable, with ADAT expandability to provide versatile solutions with a certain degree of longevity.

PreSonus Studio 1824c

The Studio 1824c interface from PreSonus offers a huge amount of connectivity and up to 24-bit 192 kHz recording at a reasonable price. It offers eight preamps and ten DC-coupled line outputs that allow you to send CV/Gate signals from your DAW.

On the digital side, you get 16 channels of ADAT I/O. In addition, the Studio 1824c is equipped with S/PDIF, MIDI I/O, and word clock out.

On the front panel, you have two independently controlled headphones outs, input gain controls, and the main level knob. What’s more, the 1824c connects via USB-C and offers latency-free monitoring for quick play-through access.

Focusrite Scarlett 18i20 3rd Gen

The widely used Scarlett 18i20 is a 24-bit 192 kHz interface with eight combo inputs and ten outputs. Two of the preamps double up as instrument inputs, and all inputs have access to the AIR function. What’s more, the optical I/O gives you 8 channels at 48 kHz or 4 channels at 96 kHz.

Aside from this, the 18i20 has S/PDIF, MIDI I/O, and word clock out. Moreover, convenient features like the built-in talkback mic makes sense when you’re working with a recording booth.

Although the headphones outputs prefer headphones with an impedance rating of 80 Ohms or higher, the Scarlett series is still a sure choice considering its reputation and you can expand your number of inputs with the Octapre and Octapre Dynamic.

Audient EVO 16

The EVO 16 is a relatively compact 24-bit 96 kHz USB interface that can be easily used in both desktop or rack mount configurations with the optional rack ears. It offers eight inputs with Smartgain, eight outputs, two sets of optical I/O ports, and word clock out.

The EVO interface is incredibly straightforward and it also allows multichannel Smartgain functionality, even when connected with the SP8 preamp expander.

All of the front panel features are adjusted via the main rotary encoder, which is certainly simple and fast. Although the design of the EVO series might not be for everyone, you certainly can’t argue with the audio quality.

Focusrite Clarett+ 8Pre

If you’re playing with a slightly bigger budget, the Clarett+ 8Pre features improved conversion, clocking, and smoother sounding mic pres than the Scarlett series. Apart from that, the features are very similar between the two.

The Clarett+ 8Pre offers eight inputs, ten outputs, eight channels of ADAT I/O, S/PDIF, word clock, and MIDI I/O. The inputs are modeled on the sound of the classic ISA110 preamps, so you certainly get your money’s worth there.

When it comes to expandability, you can add eight additional inputs via ADAT with the Clarett Octapre.
