Blackstar's Polar 2 is a standout dual-channel interface that caters specifically to guitarists, seamlessly connecting with various devices without hassle. Its 24-bit, 192kHz conversion and useful software bundle, including impressive amp modeling, elevate this interface above the competition. The Enhance feature effectively manages high transients and adds warmth, making it a joy for recording. However, some may find the lack of a USB power adapter a minor inconvenience, and while the control software is helpful, it’s not essential for basic functions. Overall, the Polar 2 combines quality, functionality, and generous software, making it a solid investment for any guitarist.

Great simple interface for use with mobile devices

Great interface to capture audio with good quality. Compact, solid and simple to use. I use it with an iPad to capture the audio of an electric guitar for different purposes: record the audio, record videos using the interface input as their audio, and using virtual amps and effects. I used it successfully when both, connecting the guitar directly, and also using a pedalboard.

The "enhance" feature provides a subtle but nice improvement. So I keep it on. Despite some added amp qualities with the "enhance" option, the clipping is still something to avoid. In any case, the level indicators make it easy to adjust the right amount of input gain to avoid clipping easily.

For my setup, using it with an old iPad (5th gen), it is great to see that it just works when connecting it (using the camera adapter since older iPads lack USB ports). The only drawbacks in my case is that the control app is not available for mobile devices. So it is not possible to change the default settings (which is not an issue for my uses). For advanced adjustments I'd need to connect a laptop. For example, activate direct monitoring or separate the inputs to different outputs require the use of the control app. Fortunately, the changes made, are preserved in the interface until it is turned off, even when connecting it back to the iPad. So this can be used as a workaround if needed.

I mention that the interface is very silent. However, that will depend on the quality of the power supply you use with it. Using a regular USB phone charger, or connecting the unit directly to my old laptop resulted in the interface to capture audio with a lot of electric noise. I had a similar experience with the another audio interface (Universal Audio Volt 2) and I returned it because it was noisy. Then, I found the Polar 2 with the promise of the silent FET-based preamps, and I was disappointed to get the same noise initially. So this may be a common issue with USB powered interface.

The noise issues were completely solved when I used a spare USB hub by elgato that has a power supply with ground connection and I no longer needed for my computer. This is a bit overkill, since the hub provides many ports for connecting a computer (USB, USBC, network, HDMI) and I'm using just one to power the audio interface. However, the result is exceptional. Total silence, unless the input gain is turned really high (over 80%).

I also tried a Harley Benton battery that works well for pedals and has a USB connection too. Although the noise was reduced to usable levels, the hub from elgato worked much better.

I think that manufacturers should provide a good power supply for users to experience their products at their best, or, at least, provide some recommendations for power supplies that work well with their device.
