Overview of the Focusrite Scarlett 18i20 and Universal Audio Volt 476p
The Focusrite Scarlett 18i20 is priced at $749.99, while the Universal Audio Volt 476p is about 17% cheaper at $449.00. This price difference reflects the varied features and intended user base of these two USB audio interfaces. The Scarlett 18i20 is designed for more complex setups with extensive inputs and outputs, whereas the Volt 476p is geared toward users looking for classic analog sound in a more compact package.
Build Quality and Design
The build quality of the Focusrite Scarlett 18i20 is robust, designed to accommodate the rigors of a studio environment. It provides 18 inputs and 20 outputs, including eight mic preamps, Hi-Z, and line inputs. This extensive I/O is perfect for users who need to connect multiple instruments or microphones simultaneously. In contrast, the Universal Audio Volt 476p is compact and portable, featuring a 4-in/4-out configuration. This makes it ideal for mobile recording, especially for users who may want to take their interface on the go.
Sound Quality
When it comes to sound quality, the Focusrite Scarlett 18i20 boasts 24-bit, 192kHz converters, ensuring a high dynamic range of 122dB. This level of detail is essential for professional recordings, whether in music production or podcasting. On the other hand, the Universal Audio Volt 476p features classic UA 610 preamps that offer a rich, album-ready sound. Additionally, it includes an analog compressor based on the renowned 1176, adding clarity and punch to recordings. Both interfaces provide high-quality audio, but the Scarlett 18i20 is more suited for high-fidelity studio environments.
Input and Output Capabilities
The Focusrite Scarlett 18i20 excels in its input and output capabilities with 18 inputs and 20 outputs, making it an industry leader in this category. With eight mic preamps and various digital connectivity options like ADAT and S/PDIF, it allows for complex routing and seamless integration with multiple devices. Conversely, the Volt 476p offers a more limited 4-in/4-out configuration. While this may suffice for solo artists or small bands, those needing extensive connectivity might find it restrictive, especially given its sales rank of 10,242 compared to the 2,965 of the Scarlett.
Software Compatibility and Bundled Features
The Focusrite Scarlett 18i20 comes with a comprehensive software bundle that includes Pro Tools Intro+, Ableton Live Lite, and Cubase LE, along with Hitmaker Expansion, which provides essential effects and powerful software instruments. This makes it an attractive option for newcomers and seasoned producers alike. In contrast, the Universal Audio Volt 476p includes the award-winning LUNA Digital Audio Workstation and a suite of UAD plug-ins, which are favored by industry professionals. This difference highlights that while both interfaces offer valuable software, the Scarlett provides a broader array of entry-level tools.
User Experience and Workflow
The Focusrite Scarlett 18i20 is designed for a professional workflow, featuring tools like Auto Gain and Clip Safe that help users manage levels efficiently. This allows artists and engineers to focus on the recording process rather than technical adjustments. Meanwhile, the Volt 476p supports user development with tips and tutorials for beginners to advanced users, making it a user-friendly choice for those new to recording. However, for more experienced users looking for intricate control, the Scarlett's advanced features may be more appealing.
Price-to-Performance Ratio
At $749.99, the Focusrite Scarlett 18i20 positions itself as a premium product in the audio interface market. Its high-quality components and extensive features justify the cost for serious musicians and podcasters. The Universal Audio Volt 476p, priced at $449.00, offers excellent value for those who need professional sound quality without the extensive I/O. The substantial price difference of about $300 may influence buyers depending on their specific needs, particularly those who may not require the extensive capabilities of the Scarlett.
Which should you buy?
Choosing between the Focusrite Scarlett 18i20 and the Universal Audio Volt 476p ultimately depends on your recording needs and budget. If you require extensive connectivity and high-fidelity sound for professional work, the Scarlett 18i20 is the better choice. However, if you prioritize portability and classic analog warmth for a more budget-friendly price, the Volt 476p would serve you well. Consider your specific requirements—whether it’s the need for multiple inputs or the desire for quality sound on the go—to make the best decision for your audio recording setup.
