Overview of the Solid State Logic SSL 2 Plus MKII and Universal Audio Volt 2
The Solid State Logic SSL 2 Plus MKII is priced at $299.99, while the Universal Audio Volt 2 comes in at $199.00, making it about 17% cheaper. Both audio interfaces cater to musicians, podcasters, and audio engineers, but they offer distinct features that appeal to different user needs. The SSL 2 Plus MKII is well-known for its professional-grade sound quality and robust build, while the Volt 2 emphasizes portability and ease of use, featuring vintage mic preamp models that aim to deliver classic sound quality.
Sound Quality and Performance
The SSL 2 Plus MKII features 32-bit / 192 kHz AD/DA converters, which provide exceptional audio fidelity and performance. This level of quality is designed for those who demand the best from their audio production. In comparison, the Volt 2 supports up to 24-bit / 192 kHz quality, which, while still impressive, is slightly lower than what the SSL offers. The Volt 2 includes a Vintage mode that emulates the classic UA 610 preamps, allowing users to capture a rich, full album-ready sound. This feature is particularly appealing to those who value vintage audio aesthetics, making both interfaces strong contenders in sound quality.
Connectivity Options
The SSL 2 Plus MKII provides a comprehensive set of connectivity options, including two XLR mic preamps, two 1/4" line/Hi-Z inputs, and four 1/4" balanced outputs. This variety makes it suitable for complex setups, whether in a studio or live setting. Additionally, it includes MIDI I/O on 5-Pin DIN jacks, enhancing its versatility for musicians who use MIDI instruments. The Volt 2, while offering two inputs and outputs, lacks the extensive output options of the SSL and does not feature MIDI connectivity. This distinction may lead users to prefer the SSL for more intricate recording setups.
Software Bundles
When it comes to software, the SSL 2 Plus MKII comes with the SSL Production Pack Software Bundle, which is tailored for music production and provides a range of professional tools. This package is likely to appeal to serious producers and musicians looking for a complete solution. On the other hand, the Volt 2 includes the award-winning LUNA Digital Audio Workstation and a suite of UAD plugins, which are industry-standard tools for recording and mixing. While both packages are strong, those who prioritize a comprehensive software offering might lean towards the Volt 2.
Portability and Design
Weighing in on portability, the Volt 2 is designed with mobile recording in mind, compatible with Mac, Windows, iPad, and iPhone. This makes it a great choice for users who need to capture ideas on the go. It also requires an external power supply for mobile use, which may be a consideration for some. In contrast, the SSL 2 Plus MKII is bus-powered, enabling a straightforward setup without the need for additional power sources, which can be advantageous for users in a studio environment. This makes the SSL slightly less portable but potentially more convenient for stationary use.
User Experience and Workflow
The SSL 2 Plus MKII is aimed at both beginners and seasoned professionals, offering features like zero-latency monitoring and high-pass filters to enhance the recording experience. Its user-friendly design allows for easy operation, making it accessible for those starting in music production. The Volt 2 also focuses on usability, providing tips and tutorials for users of all skill levels. However, its experience is generally more tailored to those who prefer a quick and simple setup for recording and streaming, making it potentially more appealing for casual users.
Pricing and Value
At $299.99, the SSL 2 Plus MKII is positioned as a premium product in the audio interface market, and it has a bestseller rank of 6139. In contrast, the Volt 2, priced at $199.00, offers significant savings while still maintaining strong performance, as reflected in its bestseller rank of 2514. Users must weigh whether the additional features of the SSL justify its higher price or if the Volt 2's more accessible price point aligns better with their needs.
Which should you buy?
Ultimately, the choice between the Solid State Logic SSL 2 Plus MKII and the Universal Audio Volt 2 depends on your specific needs and budget. If you prioritize professional-grade sound quality, extensive connectivity options, and a robust software bundle, the SSL 2 Plus MKII may be worth the investment. However, if you are looking for a more affordable, portable option that still delivers excellent audio quality and is user-friendly, the Volt 2 is an excellent choice. Both interfaces have their strengths, making them suitable for different types of users in the audio production space.
