Additionally, it comes with an AC/DC power adapter rated at 5 VDC and 3 A, which is included. This interface consumes 7.5 W of power, indicating a relatively higher power draw that necessitates the inclusion of an external power source to ensure stable performance, especially when handling more demanding tasks.
On the other hand, the Audient iD14 MKII is designed to be more straightforward in terms of power requirements, relying solely on USB bus power. This means it draws the necessary power directly from the connected USB port, eliminating the need for an external power supply. This can simplify setup and reduce cable clutter, but it may also limit the interface’s power capacity compared to the Scarlett 4i4.
In summary, the Focusrite Scarlett 4i4 provides more flexibility with multiple power options, including an external AC/DC power adapter, which supports its higher power consumption of 7.5 W. In contrast, the Audient iD14 MKII emphasizes simplicity and convenience with its exclusive reliance on USB bus power, though this might come at the cost of lower power availability.

The Focusrite Scarlett 4i4 USB-C Audio/MIDI Interface (4th Generation) and the Audient iD14 MKII Desktop 10x6 USB Type-C Audio Interface both offer robust features for audio and MIDI interfacing, but they differ significantly in their dimensions and weight.
The Focusrite Scarlett 4i4 measures 7.09 x 5.08 x 2.32 inches (18.01 x 12.9 x 5.89 cm) and weighs 1.8 lb (816.0 g). This makes it relatively compact and lightweight, suitable for both stationary setups and mobile recording scenarios. Its dimensions suggest it has a slightly larger footprint compared to the Audient iD14 MKII, providing ample space for connectivity options and controls without being overly bulky.
On the other hand, the Audient iD14 MKII is also compact but has slightly different dimensions, measuring 6.8 x 4.7 x 2.4 inches (17.3 x 12 x 6.2 cm), including controls and protrusions. While it is marginally smaller in terms of width and length when compared to the Scarlett 4i4, it has a slightly greater height, which might be attributed to its control layout and design. The iD14 MKII also includes a Kensington Security Slot, an anti-theft feature not listed for the Scarlett 4i4, which adds a layer of security for users who may need it in shared or public spaces.
In conclusion, both interfaces are compact and designed for desktop use, but the Focusrite Scarlett 4i4 is a bit larger and heavier, potentially offering a more substantial build, whereas the Audient iD14 MKII, with its security feature, may appeal to those needing additional protection for their gear.

The Focusrite Scarlett 4i4 USB-C Audio/MIDI Interface (4th Generation) and the Audient iD14 MKII Desktop 10x6 USB Type-C Audio Interface are both high-quality audio interfaces, but they differ in several key aspects.
Firstly, in terms of package weight, the Focusrite Scarlett 4i4 is heavier, weighing in at 3.185 lb, whereas the Audient iD14 MKII is lighter at 2.33 lb. This difference in weight might be a consideration for users who prioritize portability and ease of transport.
Regarding box dimensions, the Focusrite Scarlett 4i4 measures 11.2 x 8 x 3.6 inches. In comparison, the Audient iD14 MKII has a smaller footprint with dimensions of 9 x 6 x 3.6 inches. This makes the Audient iD14 MKII more compact, which could be advantageous for users with limited desk space or those who prefer a more space-efficient setup.
Both interfaces utilize USB Type-C connectivity, ensuring fast data transfer and compatibility with modern devices. However, the specific number of inputs and outputs differs: the Focusrite Scarlett 4i4 offers a 4x4 configuration, while the Audient iD14 MKII provides a 10x6 configuration, giving the Audient interface an edge in terms of input/output flexibility.
In summary, the Focusrite Scarlett 4i4 is heavier and larger in size, whereas the Audient iD14 MKII is more lightweight and compact. The Audient also offers a greater number of inputs and outputs, which might be preferable for users needing more extensive connectivity options.
