The Focusrite Scarlett 18i20 USB-C Audio/MIDI Interface (3rd Generation) and the PreSonus Studio 1824c Rackmount 18x20 USB Type-C Audio/MIDI Interface offer robust features but differ in some key areas:
In terms of OS compatibility, the Focusrite Scarlett 18i20 supports a wider range of macOS versions, starting from macOS 10.12 up to macOS 11, and Windows 7 or later. On the other hand, the PreSonus Studio 1824c is compatible with macOS 10.13 or later (64-bit only) and Windows 10 (64-bit only). This makes the Focusrite more versatile when it comes to older operating systems.
When it comes to mobile app compatibility, the Focusrite Scarlett 18i20 is compatible with iPadOS only, whereas the PreSonus Studio 1824c extends its compatibility to a variety of iPads (iPad Pro, iPad Air, iPad Air 2, iPad Mini with Retina, iPad Mini 4, iPad 4th Gen) and Android smartphones and tablets. This gives PreSonus a broader range of mobile device compatibility.
Both interfaces require an available USB 2.0 port and include a USB cable in the package. However, the PreSonus Studio 1824c also supports a USB-C port, adding a layer of flexibility for users with newer devices.
For hardware and internet requirements, both units need an internet connection for software and driver downloads. The PreSonus Studio 1824c has additional requirements such as a minimum of 4 GB RAM (8 GB recommended), 32 GB of storage, and a minimum display resolution of 1366 x 768, which are not specified for the Focusrite Scarlett 18i20.
In summary, while both audio interfaces offer high-quality audio and MIDI capabilities, the Focusrite Scarlett 18i20 shows more versatility in OS compatibility, whereas the PreSonus Studio 1824c excels in mobile device compatibility and offers additional connection flexibility with USB-C support.
