Independent shopping perspective
The Korena take
Built around guitar and vocal recording, Polar 4 combines four XLR/TRS mic preamps with FET inputs, 48V phantom power and USB-C computer connection. Its instrument Enhance control is designed to behave like a valve-amp input stage when using amp plugins, while the microphone Enhance option adds air and clarity. The ±24V input headroom is intended to simplify level setting without digital clipping. Two headphone outputs, loopback and MIDI I/O broaden its role in a recording setup.
