Overview
The Focusrite Scarlett 18i20 and the Motu M2 are two powerful audio interfaces, but they cater to different needs and budgets. The Scarlett 18i20 is priced at $749.99, while the M2 is significantly more affordable at $199.95, making it about 73% cheaper. This price difference reflects the extensive capabilities of each device, which will be explored in detail.
Connectivity and Inputs
The Focusrite Scarlett 18i20 offers a comprehensive range of connectivity options, featuring 18 inputs and 20 outputs. This includes eight mic preamps, Hi-Z, line inputs, and digital connections like ADAT and S/PDIF. In contrast, the Motu M2 has a more modest setup with two inputs and two outputs but still delivers essential connectivity, including XLR inputs. Users needing extensive tracking and routing flexibility will find the Scarlett 18i20's capabilities far superior, making it ideal for larger projects, while the M2 suits simpler setups.
Audio Quality
Audio quality is a standout feature for both interfaces. The Scarlett 18i20 is equipped with high-quality 24-bit, 192kHz converters, delivering a dynamic range of 122 dB for detailed recordings. On the other hand, the Motu M2 utilizes ESS Sabre32 Ultra DAC technology, achieving an impressive 120 dB dynamic range. While both devices provide excellent audio fidelity, the Scarlett offers slightly better specifications, making it more suited for high-end studio applications.
Preamp Performance
When it comes to preamps, the Focusrite Scarlett 18i20 excels with its eight 4th Gen mic preamps that provide up to 69 dB of gain. This feature allows for capturing dynamic performances with clarity and precision. The Motu M2, while having high-quality preamps, is limited to two inputs. The M2 does achieve a remarkable -129 dBu EIN on mic inputs, indicating its capability for low-noise recordings, but for users needing multiple channels, the Scarlett's preamp performance is unmatched.
Software Bundle
The software bundled with each audio interface can significantly enhance the user experience. The Focusrite Scarlett 18i20 includes Pro Tools Intro+, Ableton Live Lite, and Cubase LE, along with a suite of essential effects and software instruments. In comparison, the Motu M2 comes with MOTU Performer Lite and Ableton Live Lite, which also includes over 100 instruments and 6 GB of loops and samples. While both bundles provide valuable tools for music production, the Scarlett's offering is broader, appealing to users who want access to a more extensive range of software.
User-Friendly Features
User-friendly features can significantly affect workflow during recording and mixing sessions. The Scarlett 18i20 boasts professional tools like Auto Gain, which sets optimal levels quickly, and Clip Safe, which prevents clipping by adjusting gain in real-time. These features simplify the recording process and allow users to focus more on their performances. Conversely, the Motu M2 features a full-color LCD with clear level meters for all inputs and outputs, making it easy to monitor levels. While both interfaces have user-friendly elements, the more advanced features of the Scarlett 18i20 provide a more professional experience.
Portability
Portability is another crucial factor for musicians and producers on the go. The Motu M2, with its compact 2x2 design, is more portable compared to the larger Focusrite Scarlett 18i20. Weighing less and taking up less space, the M2 is ideal for mobile setups, making it an excellent option for traveling musicians. The Scarlett 18i20, while versatile and robust, is better suited for studio environments where space is less of a concern.
Price Comparison
The price difference between the two audio interfaces is substantial, with the Focusrite Scarlett 18i20 priced at $749.99 and the Motu M2 at $199.95. This makes the M2 about 73% cheaper than the Scarlett. While the Scarlett offers more inputs, outputs, and advanced features, the M2 provides exceptional value for those on a budget or needing a simpler solution. This stark contrast in pricing reflects the different target markets of each product.
Which should you buy?
Choosing between the Focusrite Scarlett 18i20 and the Motu M2 largely depends on your specific needs and budget. If you require extensive input options, superior audio quality, and advanced recording features, the Scarlett 18i20 is the clear choice, albeit at a higher price. However, if you are looking for an affordable, high-quality audio interface for basic recording needs, the Motu M2 offers remarkable performance at a fraction of the cost. Ultimately, both devices excel in their respective categories, making them excellent options for different types of users.
