Key Features of the UP2
2 microphone inputs, with dual USB interfaces supporting 32-bit/192kHz audio.
Analog 2-in/4-out, plus digital 2-in/2-out (to the secondary USB port).
Dedicated headphone amp with an ES9020Q DAC chip, ensuring independent analog signal paths for headphones.
Premium Component Selection
Preamp: PGA2500 + OPA1612 (top-tier combination)
ADC: AKM flagship AK5572EN (dual-channel conversion)
DAC: AKM flagship AK4493SEQ (dual-channel conversion)
Headphone Amp: ESS ES9020Q DAC + TPA6120 amplifier chip
Main Controller: RSIC V 648M (high-performance domestic MCU)
With this component lineup, the UP2 is undoubtedly a professional-grade recording device, pushing the limits of portable audio interfaces. Before the AKM factory fire, AKM’s ADCs and DACs were the go-to choice for pro audio gear. Now, the UP2 stands as one of the few products in its price range featuring the AK5572 + AK4493 combo, offering high dynamic range and ultra-low THD+N. Fans of AKM’s signature sound now have a new option.

Performance Highlights (Per Official Claims)
Preamp gain reaches an astonishing +85dB (vs. the typical +60dB in this class), thanks to the PGA2500’s 65dB + OPA1612’s 20dB boost.
2.5KΩ balanced input impedance—capable of driving virtually any microphone.
Line-out THD+D: -114dB
DAC dynamic range: 123.6dB (surpassing most competitors)
ADC dynamic range: 114dB, THD+N: -110dB
Lab-tested (via Audio Precision) results reportedly outperform RME, Focusrite, MOTU, and Apogee in multiple metrics.
Software & Driver Innovation
Platane emphasizes software excellence:
Windows: Custom Platane Mixer with full matrix routing (on par with RME’s TotalMix).
macOS: First domestic audio interface with a DEXT driver (no need to disable SIP).

Why drivers matter:
Hardware can be copied, but driver development requires elite programming skills—handling system kernels without crashes is no small feat. Platane’s achievement in launching self-developed Windows ASIO and macOS DEXT drivers within two years signals world-class technical prowess. In the audio world, Platane is akin to Moore Thread in GPUs: a rare domestic player mastering both hardware and software.
Design & Availability
Full aluminum alloy casing with anodized finish (reminiscent of Apple’s Mac mini in space gray).

Launch timeline: Small batches expected by mid-June, priced under ¥2000.
Given the success of its predecessor (UP1), the UP2 is poised to be a milestone for Chinese audio interfaces—potentially surpassing international brands in performance. Once market units arrive, real-world tests will confirm if it lives up to the hype.
