CrinEar Protocol Max
The Protocol Max marks CrinEar’s bold entry into the source gear market, bringing our philosophy of acoustic precision to digital-to-analog conversion and amplification. With up to 600 mW of clean power on tap from its balanced output, the Protocol Max effortlessly drives everything from sensitive in-ear monitors to demanding full-size headphones, all without breaking a sweat.
Beyond raw strength, the Protocol Max features persistent, PC browser-based parametric EQ via the Hangout.Audio Graph Tool, letting you fine-tune your sound signature and store your custom profiles directly onto the device. No companion app, no extra steps—just plug into your PC, set your curve, and enjoy.
With its blend of muscle, precision, and user-focused flexibility, the Protocol Max balances clean, reference-grade performance with real-world practicality, making it the ultimate pocket-sized DAC-amp for enthusiasts and professionals alike.
