MOTU M4 4x4 USB-C Audio Interface vs Focusrite Scarlett 2i2 4th Gen, 2-in, 2-out

Design and build quality

The MOTU M4 4x4 USB-C Audio Interface and the Focusrite Scarlett 2i2 4th Gen, 2-in, 2-out both represent solid entries in the desktop audio interface market. The MOTU M4 features a compact chassis designed to house its expanded connectivity options while maintaining a small footprint. It includes a dedicated LCD screen, which is a distinct physical feature not commonly found at this price point. The Focusrite Scarlett 2i2 4th Gen, 2-in, 2-out adheres to the familiar Scarlett design language, utilizing Dynamic Gain Halos around the gain knobs to provide visual feedback. Both units are built for studio desktop use, though the MOTU M4 4x4 USB-C Audio Interface integrates more physical controls for monitoring due to its higher channel count.

Connectivity and I/O

Connectivity is a primary differentiator between these two units. The MOTU M4 4x4 USB-C Audio Interface provides a 4-in/4-out configuration, allowing users to connect more microphones or instruments simultaneously compared to the competition. It explicitly utilizes USB-C for its computer connection, ensuring modern compatibility. In contrast, the Focusrite Scarlett 2i2 4th Gen, 2-in, 2-out offers a 2-in, 2-out setup, which is standard for entry-level interfaces but limits simultaneous recording sources. The MOTU M4 4x4 USB-C Audio Interface also includes loopback functionality, which is essential for podcasters or streamers who need to route computer audio back into the interface for broadcast.

Preamp Performance

Preamp quality is critical for capturing clean audio sources. The Focusrite Scarlett 2i2 4th Gen, 2-in, 2-out highlights its 4th-Generation mic pres, boasting a huge 69dB gain range. This specification suggests the ability to handle a wide variety of microphones, including those with lower sensitivity. The unit claims to be the clearest and most detailed ever found on a Scarlett interface. The MOTU M4 4x4 USB-C Audio Interface includes 2 Microphone Preamps but does not specify the gain range or dynamic range in the provided data. While MOTU is known for high-quality conversion, the available specifications favor the Focusrite Scarlett 2i2 4th Gen, 2-in, 2-out in terms of documented preamp metrics.

Monitoring and Display

Monitoring capabilities differ significantly in terms of user interface. The MOTU M4 4x4 USB-C Audio Interface features an LCD Screen that provides precise visual feedback on levels and settings directly on the hardware. This allows for accurate monitoring without relying solely on computer software. The Focusrite Scarlett 2i2 4th Gen, 2-in, 2-out uses Dynamic Gain Halos, which are LED rings around the knobs that change color to indicate signal status. Additionally, the Focusrite Scarlett 2i2 4th Gen, 2-in, 2-out includes Hardware Monitoring capabilities implicitly through its design, but the MOTU M4 4x4 USB-C Audio Interface explicitly lists Hardware Monitoring as a feature alongside its screen.

Software and ecosystem

Both interfaces come with software bundles to aid in production. The MOTU M4 4x4 USB-C Audio Interface includes 6+GB of Free Content compatible with Mac, PC, and iOS. This cross-platform support expands its utility for users working across different devices. The Focusrite Scarlett 2i2 4th Gen, 2-in, 2-out typically includes software bundles as part of the Scarlett ecosystem, though specific content size is not detailed in the provided data. Both units are designed to integrate seamlessly with major DAWs, but the MOTU M4 4x4 USB-C Audio Interface specifies iOS compatibility, which may be advantageous for mobile recording setups.

Special Features

Unique features can sway the decision for specific use cases. The Focusrite Scarlett 2i2 4th Gen, 2-in, 2-out introduces Air Mode, which adds high-end presence and rich harmonic drive to vocals and instruments, emulating classic console characteristics. It also features Auto Gain, which sets the perfect level after ten seconds of play, and Clip Safe, which automatically adjusts gain to prevent clipping. The MOTU M4 4x4 USB-C Audio Interface focuses on utility with its Loopback feature and LCD screen. While the Focusrite Scarlett 2i2 4th Gen, 2-in, 2-out offers more automated assistance for gain staging, the MOTU M4 4x4 USB-C Audio Interface offers more manual control and routing options.

Price and value

Price is a significant factor for home studio builders. The Focusrite Scarlett 2i2 4th Gen, 2-in, 2-out is listed at $224.99, making it the more affordable option between the two. The MOTU M4 4x4 USB-C Audio Interface is priced at $268.00. The price difference reflects the additional I/O count and the inclusion of the LCD screen on the MOTU unit. For users who only need two inputs, the Focusrite Scarlett 2i2 4th Gen, 2-in, 2-out presents a strong value proposition with its advanced preamp features. However, for those needing expandability, the extra cost of the MOTU M4 4x4 USB-C Audio Interface may be justified by the 4-in/4-out capability.

Which one should you buy?

Choosing between the MOTU M4 4x4 USB-C Audio Interface and the Focusrite Scarlett 2i2 4th Gen, 2-in, 2-out depends on your specific recording needs. If you require more than two inputs simultaneously or want visual level monitoring via an LCD screen, the MOTU M4 4x4 USB-C Audio Interface is the superior choice. Its loopback feature also makes it better suited for content creators. However, if you are a solo musician or podcaster working with a single microphone or instrument, the Focusrite Scarlett 2i2 4th Gen, 2-in, 2-out offers excellent preamp specifications, smart gain features like Auto Gain and Clip Safe, and a lower price point. Both are capable interfaces, but the MOTU M4 4x4 USB-C Audio Interface wins on versatility while the Focusrite Scarlett 2i2 4th Gen, 2-in, 2-out wins on documented preamp performance and value.
