The impedance levels vary as well, with the Scarlett 4i4 featuring a lower headphone output impedance (<11 Ohms) compared to the Scarlett 8i6 (<1 Ohm). This can impact the performance and compatibility with different headphone models. When it comes to dynamic range, the Scarlett 4i4 generally provides higher figures. For instance, its 1/4" Line Outputs feature a dynamic range of 120 dB, while the Scarlett 8i6 offers 108.5 dBA. Similarly, the Scarlett 4i4’s Combo XLR-1/4" Mic Inputs boast a dynamic range of 116 dBA, compared to the Scarlett 8i6’s 111 dBA for Mic Inputs. In terms of Total Harmonic Distortion plus Noise (THD+N), the Scarlett 4i4 offers better performance figures across most inputs and outputs. For example, the 1/4" Line Inputs on the Scarlett 4i4 have a THD+N of -105 dB, while the Scarlett 8i6’s Line Inputs have a THD+N of <0.002%. This suggests that the Scarlett 4i4 might provide cleaner audio with less distortion. Lastly, the Equivalent Input Noise (EIN) shows a slight edge for the Scarlett 8i6 with -128 dB A-weighted compared to the Scarlett 4i4’s -127 dBu A-weighted, indicating that the Scarlett 8i6 might have marginally lower self-noise. In summary, while both interfaces offer professional-grade audio performance, the Scarlett 4i4 (4th Generation) generally provides higher dynamic range and lower THD+N values, indicating potentially cleaner and more precise audio capabilities. The Scarlett 8i6 (3rd Generation), on the other hand, offers higher maximum input levels and can accommodate louder sources, making it slightly more versatile in certain scenarios.

The Focusrite Scarlett 4i4 USB-C Audio/MIDI Interface (4th Generation) and the Focusrite Scarlett 8i6 8x6 USB Audio/MIDI Interface (3rd Generation) have several key differences and similarities in their specifications. Starting with sample rates, the Scarlett 4i4 offers a consistent range of 44.1 / 48 / 88.2 / 96 / 176.4 / 192 kHz, providing versatility for various recording needs. On the other hand, the Scarlett 8i6 supports sample rates up to 192 kHz for AD/DA conversion, allowing for high-resolution audio quality but does not specify individual rates like the 4i4 does. Regarding bit depths, both interfaces support 24-bit resolution, which ensures high-quality audio recording and playback. However, the Scarlett 8i6 specifies that this bit depth is applicable to AD/DA conversion processes. In terms of sync sources, the Scarlett 4i4 relies solely on an internal sync source, which is standard for many compact interfaces. In contrast, the Scarlett 8i6 offers more flexibility with both internal and S/PDIF sync sources, catering to more complex studio setups that may require digital synchronization with other equipment. These comparisons reflect the primary distinctions and similarities between these two interfaces based on the provided specifications, highlighting the 4i4's straightforward approach and the 8i6's additional synchronization capabilities.

The Focusrite Scarlett 4i4 USB-C Audio/MIDI Interface (4th Generation) and the Focusrite Scarlett 8i6 8x6 USB Audio/MIDI Interface (3rd Generation) have distinct differences in their power requirements and specifications. The Scarlett 4i4 (4th Generation) is versatile in its power options, offering USB Bus Power and the ability to use a USB Power Adapter (not included). Additionally, it includes an AC/DC power adapter that operates at 5 VDC and 3 A, with a total power consumption of 7.5 W. This flexibility allows users to choose between powering the interface directly from their computer via USB or using an external power source, making it a convenient option for both studio and mobile recording setups. On the other hand, the Scarlett 8i6 (3rd Generation) relies solely on an included AC/DC power adapter for its power requirements. The adapter provides 12 VDC at 1 A with a center-positive configuration. This setup indicates that the 8i6 needs a dedicated external power source, which can be seen as a more traditional and perhaps stable power supply method compared to the 4i4's USB bus power option. In summary, the Scarlett 4i4 (4th Generation) offers more flexibility with its power options, including USB Bus Power and an AC/DC adapter with higher power consumption, while the Scarlett 8i6 (3rd Generation) relies on a single, included AC/DC power adapter for its operation.
