Overview of the Products
When comparing the Audient Audio Interface iD14 MKII to the Focusrite Scarlett 18i20, the most notable difference is in their intended use cases and price points. The Audient iD14 MKII is priced at $318.40, making it about 57% cheaper than the Scarlett 18i20, which comes in at $749.99. This significant price difference reflects the different target audiences and functionalities of each interface. While both are high-quality audio interfaces, their features cater to distinct user needs in music production and recording.
Design and Build Quality
The Audient iD14 MKII offers a robust all-metal desktop housing, which enhances its durability and portability. Weighing in at 1250 grams, this interface is designed for easy transport, making it ideal for musicians on the go. In contrast, the Focusrite Scarlett 18i20, while also built for professional use, features a more extensive connectivity option with 18 inputs and 20 outputs, indicating a larger and potentially less portable design. The Scarlett’s additional features may suit a studio environment better, but the iD14 MKII’s compact design excels for mobile setups.
Audio Quality
Audio quality is a critical factor for any audio interface, and both the Audient iD14 MKII and the Focusrite Scarlett 18i20 deliver impressive sound performance. The iD14 MKII boasts two Class-A microphone preamps derived from Audient's high-end ASP8024 HE console, ensuring high-fidelity recordings. Conversely, the Scarlett 18i20 leverages 24-bit, 192kHz converters, offering a dynamic range of 122dB, which may appeal to those seeking professional-grade recordings. The Scarlett's preamps provide 69dB of gain, giving it a slight edge for capturing dynamic performances, especially in a studio setting.
Connectivity Options
When it comes to connectivity, the Focusrite Scarlett 18i20 clearly stands out with its 18 inputs and 20 outputs, including eight mic preamps and various digital I/O options such as ADAT and MIDI. This extensive connectivity caters well to multitrack recording and complex setups. On the other hand, the Audient iD14 MKII features a more streamlined setup with two Class-A preamps and a high-speed USB-C connector for easy handling. While the iD14 MKII is sufficient for simpler recording tasks, the Scarlett 18i20's versatility makes it more suitable for larger projects requiring multiple inputs.
Software Bundles
Both interfaces come with software bundles, enhancing their value. The Audient iD14 MKII includes essential software for recording and production, but details on the specific applications included are less emphasized. In contrast, the Focusrite Scarlett 18i20 provides a comprehensive bundle that includes Pro Tools Intro+, Ableton Live Lite, and Cubase LE, among others. This suite equips users with a robust toolkit for music production right out of the box, making it an appealing choice for those who want immediate access to professional software.
User Experience
User experience is a crucial aspect when selecting an audio interface. The Audient iD14 MKII emphasizes ease of use with features like monitor mix and monitor panning functions, making it user-friendly for beginners and seasoned musicians alike. Meanwhile, the Scarlett 18i20 incorporates professional workflow tools such as Auto Gain and Clip Safe, which automatically optimize levels and prevent clipping during recordings. This advanced functionality might require a steeper learning curve but ultimately provides greater control for experienced users.
Pricing and Value
In terms of pricing, the Audient iD14 MKII at $318.40 is significantly more budget-friendly compared to the Focusrite Scarlett 18i20 priced at $749.99. This price difference of about 57% makes the iD14 MKII an attractive option for those who need quality audio recording without breaking the bank. However, the Scarlett 18i20 justifies its higher price with its extensive features and functionalities designed for professional studio use. For users who prioritize advanced connectivity and software, the investment in the Scarlett may be worthwhile.
Which should you buy?
Choosing between the Audient iD14 MKII and the Focusrite Scarlett 18i20 ultimately depends on your specific needs and budget. If you're a musician or podcaster looking for a straightforward, high-quality interface for home recording, the Audient iD14 MKII is a cost-effective solution that offers excellent audio quality and portability. However, if you require a more comprehensive setup for multitrack recording or professional music production, the Focusrite Scarlett 18i20’s advanced features and connectivity options may be worth the higher price. Consider your recording environment and requirements carefully to make the best choice for your audio needs.
