CrinEar Protocol Max

Product information "CrinEar Protocol Max"
Portable USB-powered DAC amplifier 

  • Two Cirrus Logic DAC chips (CS43198): Provide transparent, high-resolution digital conversion. 
  • Two SG Micro SGM8262-2 operational amplifiers: Provide up to 600 mW of clean, robust amplification with minimal distortion. 
  • Adjustable and persistent parametric EQ: Upload and save custom EQ profiles directly from your PC browser. 
  • Two power modes: Optimize either efficiency (Eco) or maximum power (Boost). 
  • Sleek aluminum housing: Durable yet stylish construction for everyday transport. 
  • Wide output support: Balanced 4.4 mm and unbalanced 3.5 mm outputs with low output impedance for maximum compatibility. 

The Protocol Max marks CrinEar's bold entry into the source device market, bringing their philosophy of acoustic precision to digital-to-analog conversion and amplification. 
With up to 600 mW of clean power from its balanced output, the Protocol Max effortlessly drives everything from sensitive in-ear monitors to demanding full-size headphones, all without any issues. 
Beyond its pure power, the Protocol Max features persistent, PC browser-based parametric EQ via the Hangout.Audio Graph Tool, allowing you to fine-tune your sound character and save your custom profiles directly to the device. 
No companion app, no extra steps—just plug it into your PC, set the curve, and enjoy. 
With its combination of power, precision, and user-centric flexibility, the Protocol Max offers a balanced blend of clean reference performance and practical everyday usability, making it the ultimate pocket-sized DAC amplifier for enthusiasts and professionals alike.
