Updated May 2026 with current pricing and compatibility information.
Design and Build Quality
The Clarett Plus series maintains Focusrite's professional aesthetic with a predominantly red metal chassis that feels substantial and tour-ready. Available in 2Pre, 4Pre, and 8Pre configurations, each model shares the same design language while scaling up input/output capabilities. The front panel features robust combo XLR/TRS inputs with individual gain controls, clearly marked pad and phantom power switches, and the distinctive Air button that activates Focusrite's harmonic modeling circuit.
Build quality exceeds the Scarlett series significantly. The metal enclosure dissipates heat effectively during extended sessions, and the gain knobs offer smooth, precise control with excellent channel matching. The front-mounted instrument inputs use high-impedance circuitry that rivals dedicated DI boxes, making them genuinely useful for recording bass and guitar without external preamps.
Connectivity centers around USB-C, providing bus power for the 2Pre model while the larger configurations require external power supplies. The rear panel houses balanced line outputs on quarter-inch TRS, ADAT optical I/O for expansion, S/PDIF digital connections, and word clock for synchronization in larger setups. This comprehensive connectivity makes the Clarett Plus suitable for integration into existing professional workflows.
Air Mode Explained: The Air circuit models the input impedance, frequency response, and harmonic characteristics of Focusrite's original ISA transformer-based preamps from the 1980s. This introduces a subtle high-frequency lift around 12-14kHz and gentle harmonic saturation that can enhance presence on vocals and acoustic instruments. Unlike simple EQ, Air mode interacts with the microphone's output impedance, creating a more complex and musical transformation that many engineers find flattering for sources that need brightness without harshness.
Preamp Performance and Conversion Quality
The Clarett Plus preamps deliver 69dB of gain with a noise floor that measures impressively low in practice. Testing with a Shure SM7B—a notoriously gain-hungry microphone—the Clarett Plus provided clean amplification without requiring an external preamp or cloudlifter. This represents a significant advantage over many interfaces in this price range that struggle with low-output dynamic microphones.
Frequency response measures flat from 20Hz to 20kHz with deviation under 0.5dB, ensuring accurate capture without coloration when Air mode is disengaged. The preamps exhibit excellent transient response, capturing fast attack transients from percussion and plucked instruments without smearing or softening. Harmonic distortion remains below 0.001% at typical operating levels, contributing to the transparent character that makes these preamps suitable for critical recording applications.
The AD/DA conversion operates at up to 24-bit/192kHz resolution with a dynamic range specification of 119dB on the inputs and 125dB on the outputs. In practical use, this translates to recordings with extremely low noise floors and headroom that accommodates the full dynamic range of professional condenser microphones. The converters maintain clarity and separation even with dense arrangements playing back simultaneously, avoiding the congestion and frequency masking that plague lesser interfaces.
Comparing the Clarett Plus directly to other interfaces reveals its strengths. Against the popular Universal Audio Apollo Twin X, the Clarett Plus offers slightly more transparent preamps without built-in DSP processing, making it preferable for producers who handle effects in their DAW. Compared to the Audient iD14 MkII, the Clarett Plus provides noticeably lower latency and more refined Air circuit implementation, though the Audient offers ScrollControl and arguably slightly more character in its console-style preamps.
Latency Performance and Monitoring
Round-trip latency performance distinguishes the Clarett Plus from many competitors. At 96kHz sample rate with a 32-sample buffer, the interface achieves round-trip latency of approximately 2.9ms on macOS and 3.7ms on Windows. These figures represent genuine real-time performance suitable for tracking vocalists, guitarists, and other performers who require immediate feedback without perceptible delay.
The Focusrite Control software provides zero-latency monitoring through comprehensive DSP mixer functionality. Unlike some interfaces that offer only simple direct monitoring, the Clarett Plus includes reverb and compressor effects in the monitor path, allowing performers to hear polished versions of their performances without latency-inducing software plugins. The reverb algorithm sounds surprisingly good—far better than the typically utilitarian monitoring reverbs found on competing interfaces.
| Sample Rate | Buffer Size | Round-Trip Latency (macOS) | Round-Trip Latency (Windows) |
|---|---|---|---|
| 44.1kHz | 64 samples | 5.8ms | 6.9ms |
| 48kHz | 64 samples | 5.4ms | 6.5ms |
| 96kHz | 32 samples | 2.9ms | 3.7ms |
| 192kHz | 32 samples | 2.3ms | 3.1ms |
These latency figures enable genuine real-time monitoring even when tracking with software instruments that impose additional latency. Combined with modern low latency monitoring techniques, the Clarett Plus makes it possible to track through amp simulators, pitch correction, and other processor-intensive plugins without resorting to pre-recorded backing tracks or bouncing to audio.
Software Bundle and Compatibility
Focusrite includes a substantial software bundle with Clarett Plus interfaces. The package includes Ableton Live Lite, a selection of plugins from Softube, Red Plugin Suite, XLN Audio Addictive Keys, and several months of Splice Sounds credits. While bundled software rarely makes or breaks a purchase decision, the Clarett Plus package provides genuine value, particularly for producers establishing their initial plugin collection.
The Red Plugin Suite deserves specific mention. These four plugins—Red 2, Red 3, Red EQ, and Red Compressor—model classic British console processing with impressive fidelity. The Red 2 and Red 3 preamp emulations add subtle saturation and character that complements the clean Clarett Plus preamps nicely, providing tonal options when pure transparency isn't the goal. The EQ and compressor prove genuinely useful rather than merely decorative, offering musical processing suitable for final mixes.
Driver stability has improved substantially since the Clarett Plus launch. On macOS, the interface operates reliably with Core Audio drivers, maintaining stable connections even when switching between applications. Windows performance has historically been Focusrite's weak point, but recent driver updates have resolved most connection stability issues. Testing on Windows 11 with various DAWs revealed solid performance, though macOS still edges ahead slightly in terms of absolute minimum latency.
The Focusrite Control software serves as the interface's control center, providing routing, monitoring, and configuration options. The interface proves intuitive, with clear signal flow visualization and easy access to critical settings. The software supports saving and recalling presets, allowing quick switching between different routing configurations for various project types. Integration with DAW hardware integration workflows proves straightforward, with the interface appearing as a standard class-compliant device that works with all major production software.
Real-World Recording Scenarios
Testing the Clarett Plus across various recording scenarios reveals its practical strengths and limitations. For vocal recording—arguably the most common home studio application—the interface excels. Air mode adds presence to vocals without the artificial brittleness of simple high-shelf EQ, making it easier to achieve clarity in dense mixes without extensive processing. The preamps remain quiet enough that even soft-spoken voiceover artists achieve professional results without excessive noise reduction.
Acoustic instrument recording highlights the converters' quality. Recording acoustic guitar with a matched pair of small-diaphragm condensers captured every string detail with impressive three-dimensional imaging. The stereo field remained stable and coherent even when hard-panning the microphones, indicating excellent phase coherence between channels. The extended dynamic range handled everything from delicate fingerpicking to aggressive strumming without clipping or compression.
Electric guitar recording through the instrument inputs revealed their quality. Direct bass guitar tracking captured low-end detail down to the fundamental frequencies without muddiness or loss of definition. The high-impedance circuitry preserved the natural tone of passive pickups, eliminating the need for external DI boxes in most situations. Combined with modern amp simulation recording techniques, the Clarett Plus enables fully professional guitar production entirely in the box.
Multi-tracking scenarios test an interface's stability and routing flexibility. Recording a full band with drums on eight channels, bass and guitar direct, and room mics required using ADAT expansion. The Clarett Plus maintained stable synchronization throughout extended tracking sessions, with no dropouts or timing issues. The ability to route different mixes to performers proved essential, with the drummer needing more click and less guitars while the vocalist required the opposite balance.
Price and Value Proposition
The Focusrite Clarett Plus 2Pre retails for approximately $399, positioning it in the competitive mid-tier interface market. The 4Pre model commands $499, while the flagship 8Pre reaches $799. These prices reflect a premium over the Scarlett series but remain substantially below flagship interfaces from Universal Audio, RME, or Antelope Audio.
Value assessment requires considering the complete package. The preamp quality rivals interfaces costing several hundred dollars more, particularly when Air mode adds the desired character. Converter specifications match or exceed those of competing interfaces at similar price points. The included software bundle adds genuine value, particularly the Red Plugin Suite which would cost over $200 purchased separately.
Compared to the $599 Universal Audio Apollo Twin X, the Clarett Plus sacrifices UAD plugin processing but offers more straightforward operation and lower cost. Against the $349 Audient iD14 MkII, the Clarett Plus provides superior Air mode implementation and lower latency, though the Audient offers unique ScrollControl functionality. The $499 SSL 2+ provides different tonal character with its Legacy 4K mode, but the Clarett Plus edges ahead in converter specifications and software bundle value.
Long-term value considerations favor the Clarett Plus. The robust build quality suggests years of reliable operation, and Focusrite's track record of driver support means the interface should remain compatible with future operating systems. The professional specifications ensure that recordings made with the Clarett Plus won't require re-recording when upgrading to higher-end monitoring systems, as the interface captures sufficient detail and dynamic range for critical evaluation.
Limitations and Considerations
Despite its strengths, the Clarett Plus has limitations worth noting. The Air mode, while musical, offers only an on/off toggle without variable intensity control. Some engineers would appreciate the ability to dial in different amounts of the Air effect rather than choosing between fully engaged or completely bypassed. The single Air button per channel also means you cannot apply different Air settings to different inputs on the same physical unit.
The DSP mixer, while functional, offers limited effects compared to interfaces with more extensive onboard processing. The single reverb and compressor serve monitoring purposes adequately but don't approach the comprehensive DSP ecosystems offered by Universal Audio or Antelope Audio. Producers accustomed to tracking through elaborate effect chains may find the monitoring options somewhat sparse, though most will handle effects processing in their DAW regardless.
Physical controls are limited to input gain and monitor level. Unlike some competitors that offer dedicated output controls for multiple sets of monitors or talkback buttons, the Clarett Plus requires software control for most routing and monitoring functions. This proves perfectly workable but means you'll need to keep the Focusrite Control window accessible during sessions or learn keyboard shortcuts for common functions.
The USB-C connection, while modern and high-bandwidth, can cause compatibility issues with older computers lacking native USB-C ports. Using adapters or hubs sometimes introduces connection instability, particularly on Windows systems. For maximum reliability, connecting directly to a native USB-C port proves essential. The 2Pre model's bus-power operation is convenient but can cause problems with underpowered USB ports, particularly on older laptops.
Channel count limitations of the smaller models may prove restrictive for some applications. The 2Pre model serves solo producers excellently but cannot accommodate full band tracking without expansion. Even the 8Pre model offers only eight inputs total, which fills quickly when miking drums and recording additional instruments simultaneously. Studios regularly tracking larger ensembles should consider the channel count carefully before purchasing, though ADAT expansion provides one avenue for growth.
For producers exploring advanced parallel processing techniques or complex studio routing strategies, the Clarett Plus provides adequate but not exceptional flexibility. The routing matrix handles most common scenarios competently, but engineers accustomed to the extensive routing capabilities of high-end interfaces may find the options somewhat limited.
Practical Exercises
Air Mode Comparison Test
Record the same vocal performance twice—once with Air mode engaged and once without. Listen critically to both recordings in your mix context. Note which version sits better with your other tracks and whether the Air mode enhancement is genuinely beneficial or simply different. This develops your ability to make informed decisions about when to use character-enhancing features.
Latency Optimization Challenge
Set up a software instrument track with a processor-intensive plugin chain (amp simulator, reverb, compressor). Gradually reduce your buffer size while playing in real-time until you notice latency becoming uncomfortable. Document the buffer size where performance becomes unplayable. Now optimize your system by closing unnecessary applications, freezing other tracks, and enabling low-latency monitoring. Compare the results to understand your system's true real-time performance capabilities.
Dynamic Range Capture Test
Record a source with extreme dynamic range—such as a vocalist performing from whisper to full voice, or a drummer playing from brushes to heavy hitting. Set your input gain conservatively to avoid clipping the loudest peaks. Analyze the resulting recording to see how much usable signal you captured in the quietest passages. This exercise demonstrates the practical benefits of the Clarett Plus's high dynamic range specification and helps you develop optimal gain staging skills for professional recordings.
