CrinEar Protocol Max

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 // SPECIFICATIONS – DAC: Dual Cirrus Logic CS43198 – Amp: Dual SG Micro SGM8262-2 – Maximum Power Output (4.4mm Balanced): @ 8¦¸: 31.3 mW (Eco), 442 mW (Boost) @ 16¦¸: 62.5 mW (Eco), 600 mW (Boost) @ 32¦¸: 31.3 mW (Eco), 500 mW (Boost) @ 300¦¸: 3.5 mW (Eco), 54 mW (Boost – Maximum Power Output (3.5mm SE): @ 8¦¸: 31.3 mW (Eco), 500 mW (Boost) @ 16¦¸: 15.63 mW (Eco), 250 mW (Boost) @ 32¦¸: 7.8 mW (Eco), 125 mW (Boost) @ 300¦¸: 0.8 mW (Eco), 13.5 mW (Boost) – SNR (@1kHz 0dBFS): 132dB (4.4mm BAL), 127dB (3.5mm SE) – THD+N (@1kHz 0dBFS): -118dB (4.4mm BAL), -116dB (3.5mm SE) – Crosstalk (@1kHz -6dBFS): -116dB (4.4mm BAL), -65dB (3.5mm SE) – Output Impedance: <0.4 Ohms
