$32.25The Story
The Protocol Max marks CrinEar's bold entry into the source gear market, bringing their philosophy of acoustic precision to digital-to-analog conversion and amplification. With up to 600mW of clean power on tap from its balanced output, the Protocol Max effortlessly drives everything from sensitive in-ear monitors to demanding full-sized 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.
- Dual Cirrus Logic CS43198 DAC chips provides transparent, high-resolution digital conversion
- Dual SG Micro SGM8262-2 Op-amps provides up to 600mW of clean, robust amplification with minimal distortion
- Adjustable and presistent parametric EQ that you can upload and store custom EQ profiles directly from your PC browser
- Dual power modes to optimize for either efficiency (Eco) or maximum output (Boost)
- Sleek aluminium housing for a durable yet stylish construction made for everyday portability
- Broad output support with 4.4mm balanced and 3.5mm single-ended outputs with low output impedance for maximum compatibility
