Two of their most popular models, the Scarlett 2i2 and 4i4, have garnered significant attention from musicians, podcasters, and content creators alike. This comprehensive comparison will delve into the intricacies of both interfaces, exploring their features, performance, and overall value to help you determine which one best suits your needs.
Overview of Focusrite Scarlett Series
Before diving into the specifics of the 2i2 and 4i4, it’s essential to understand the Scarlett series as a whole. Focusrite’s Scarlett line is renowned for its exceptional sound quality, robust build, and user-friendly design. These USB audio interfaces are designed to provide professional-grade recording capabilities at an accessible price point, making them popular choices for a wide range of users, from beginners to seasoned professionals.
Scarlett 2i2: The Compact Powerhouse
The Scarlett 2i2 is Focusrite’s best-selling audio interface, and for good reason. It’s a compact, two-input, two-output device that offers impressive audio quality in a portable package. The 2i2 is ideal for singer-songwriters, podcasters, and small project studios where simplicity and quality are paramount.
Scarlett 4i4: Expanded Connectivity
The Scarlett 4i4, on the other hand, is a step up in terms of input and output options. As the name suggests, it offers four inputs and four outputs, making it a more versatile choice for users who require additional connectivity. This model is particularly well-suited for small bands, electronic musicians, and home studios that need to record multiple sources simultaneously.
Physical Design and Build Quality
Both the Scarlett 2i2 and 4i4 share Focusrite’s signature red aluminum unibody chassis, which not only looks sleek but also provides durability and protection for the internal components. The build quality of both units is exceptional, with a solid feel that inspires confidence in their longevity.
Scarlett 2i2 Design
The 2i2 measures 175mm x 98mm x 44mm, making it incredibly compact and easy to transport. Its small footprint is perfect for desktop setups where space is at a premium. The front panel features two combination XLR/TRS inputs, each with its own gain control and LED indicator ring. These rings provide visual feedback on input levels, changing color from green to orange to red as the signal approaches clipping. The unit also includes a large monitor level knob and a direct monitor switch for zero-latency monitoring.
Scarlett 4i4 Design
The 4i4 is slightly larger, measuring 215mm x 98mm x 44mm. While still compact, it offers more real estate on the front panel to accommodate additional features. Like the 2i2, it has two combination XLR/TRS inputs on the front, but it adds two line-level inputs on the back panel. The front panel also includes a larger MIDI activity LED, an AIR button for engaging Focusrite’s AIR mode, and separate headphone volume controls for two independent headphone outputs.
Input and Output Configuration
The primary difference between the 2i2 and 4i4 lies in their input and output configurations, which significantly impact their versatility and potential applications.
Scarlett 2i2 I/O
The 2i2 offers:
– Two combination XLR/TRS inputs on the front panel
– Two balanced TRS outputs on the back panel
– One headphone output on the front panel
This configuration is ideal for recording one or two sources simultaneously, such as a vocalist and a guitar, or a stereo instrument. The balanced outputs allow for connection to studio monitors, while the headphone output enables private monitoring.
Scarlett 4i4 I/O
The 4i4 expands on this with:
– Two combination XLR/TRS inputs on the front panel
– Two line-level TRS inputs on the back panel
– Four balanced TRS outputs on the back panel
– Two independent headphone outputs on the front panel
– MIDI In/Out ports on the back panel
This expanded I/O makes the 4i4 suitable for more complex recording scenarios, such as recording a full drum kit, multiple vocalists, or a small ensemble. The additional outputs also allow for more sophisticated monitoring setups or connection to external effects processors.
Preamp Quality and Performance
Both the 2i2 and 4i4 feature Focusrite’s renowned preamps, which have been a hallmark of the company’s products for years. These preamps offer exceptional clarity, low noise, and high headroom, ensuring that your recordings capture every nuance of the source material.
Scarlett 2i2 Preamps
The 2i2 boasts two of Focusrite’s 3rd generation preamps, which provide up to 56dB of gain. These preamps offer a clean, transparent sound that faithfully reproduces the source material without coloration. The high headroom ensures that even dynamic sources like drums or brass instruments can be recorded without distortion.
Scarlett 4i4 Preamps
The 4i4 features the same high-quality preamps as the 2i2 on its two front-panel inputs. However, it also includes Focusrite’s AIR mode, which emulates the company’s legendary ISA preamps. When engaged, AIR mode adds a subtle high-end boost and harmonic content, reminiscent of classic analog gear. This feature can be particularly useful for adding air and presence to vocals or acoustic instruments.
Digital Conversion and Sample Rates
Both the 2i2 and 4i4 offer professional-grade analog-to-digital and digital-to-analog conversion, ensuring that your audio is captured and played back with exceptional fidelity.
Scarlett 2i2 Conversion
The 2i2 supports sample rates up to 192kHz and bit depths up to 24-bit. This high-resolution capability ensures that even the most subtle details in your audio are captured accurately. The converters in the 2i2 offer a dynamic range of 110dB (A-weighted), providing ample headroom for recording a wide range of sources.
Scarlett 4i4 Conversion
The 4i4 matches the 2i2 in terms of sample rates and bit depths, also supporting up to 192kHz/24-bit recording and playback. However, the 4i4 boasts a slightly improved dynamic range of 111dB (A-weighted) on its analog inputs, offering marginally better performance in capturing extremely quiet sources or preserving detail in loud, dynamic recordings.
Software Bundle and Integration
Both the Scarlett 2i2 and 4i4 come with an impressive software bundle, providing users with a comprehensive set of tools to start recording and producing music right out of the box.
Scarlett 2i2 Software
The 2i2 includes:

Scarlett 4i4 Software
The 4i4 includes all of the software bundled with the 2i2, plus:
– Focusrite Control: A software mixer that provides more advanced routing and monitoring options
This additional software gives 4i4 users more flexibility in managing their audio routing and monitoring setup, which can be particularly useful when working with multiple inputs and outputs.
Latency and Performance
Low latency is crucial for real-time monitoring and recording, especially when overdubbing or using virtual instruments. Both the 2i2 and 4i4 offer excellent latency performance, thanks to Focusrite’s driver optimization and hardware design.
Scarlett 2i2 Latency
The 2i2 boasts impressively low round-trip latency, with measurements as low as 2.74ms at 96kHz with a 32-sample buffer. This performance allows for near-real-time monitoring, making it possible to record overdubs or play virtual instruments without noticeable delay. The direct monitoring feature also allows for zero-latency monitoring of input signals, bypassing the computer entirely.
Scarlett 4i4 Latency
The 4i4 offers similarly excellent latency performance, with round-trip measurements matching those of the 2i2. However, the 4i4’s additional inputs and outputs, coupled with the Focusrite Control software, provide more flexibility in routing and monitoring. This can be particularly useful in complex recording scenarios where custom monitor mixes are required.
