The Platane UP1 (USB Pro Interface) audio interface is designed for professional audio work, focusing on portability while achieving high signal-to-noise ratios and sound quality. It aims to eliminate noise and enhance audio quality while providing an ultra-low latency experience.

The UP1 is crafted from aluminum alloy with featuring a matte finish that effectively shields against electromagnetic interference. It excels in both tactile feel and durability. It supports a sampling precision of up to 32Bit/192KHz, with 3 inputs and 4 outputs, as well as 1 mic/instrument input and 2-channel headphone output. It is compatible with both Windows and Mac OS.

To maximize noise reduction on speaker, the UP1 choose knob-less design, utilizing the new PGA amplifier circuit chip and ADC chip from TI company to process digital signals. These two advanced chips work in tandem, effectively minimizing the impact of unnecessary circuitry on sound quality.

The circuit design employs a Crystal amplifier with an input gain of up to 64dB, capable of driving various low-sensitivity microphones. With a 5k input impedance, it also accommodates high-impedance microphones. The mic preamp features dual amplification, providing a 20dB gain with slight coloration to enhance the recorded sound while maintaining audio fidelity.

The instrument input uses a JFET circuit with a 1M Ω Hi-Z input, making it ideal for connecting high-impedance instruments like electric guitars or basses. It effectively drives the instrument's input signal while balancing interference noise, ensuring the output remains bright and clear.

The headphone output continues the knob-less design to eliminate potential noise while offering precise digital control which enhancing the balance between the left and right channels. It features the latest TPA6120 high-current headphone amplifier chip from TI company, delivering a high-fidelity listening experience. The gain can reach 16dB, with dynamic range of 124dB.

Additionally, the absence of knobs and the adoption of fully digital control mean there will be no hardware aging issues like noise from worn-out knobs, resulting in a longer lifespan compared to conventional knob-based sound cards.

The headphone jack supports a maximum current of 700mA, allowing for transient output. It can drive any high-power headphones and accurately capture low-frequency sounds, ensuring all musical details are preserved.

With the newest technology from Platane, the UP1 employs digital synchronous transmission for seamless signal transfer between mobile OTG and computer USB, providing lossless digital signals for an enhanced audio experience during live streaming.
It features automatic synchronization, allowing mobile devices to match the computer's audio sample rate in real-time, eliminating the need for a separate converter.

Many audio interface suffer from mismatched data transmission rates between the computer and audio interface, potentially leading to distortion or clipping. To solve this problem, the UP1 has developed a unique asynchronous synchronization function. It can communicate its processing capacity to the computer, which adjusts its data packet transmission rate accordingly, maintaining stability and preventing playback issues due to varied data transfer speeds.

With dedicated drivers from Platane, the UP1 enables high-speed digital signal transfer, allowing users to experience minimal latency. It comes equipped with Platane's total Mixer, enabling users to adjust sampling rates, latency, output channels, and other practical functions as needed.
Platane has complete hardware and software development and production capabilities for the UP1, ensuring customers need not worry about future upgrades or after-sales service.

Where will the sound come from the speakers?

It incorporates a speakerless design to ensure no noise will be present ever.

Given that there are no speaker outputs, this is intended to be a portable device.

Given that this is intended to be a portable device, it would be helpful to include the size/weight of the interface.

This is a very niche product without speaker outs, but 32-bit recording + custom drivers is an interesting combination.

Hello
The size is 98mm x 67mm x 41mm.
The weight is 210g

Hello
Sorry we forgot put thoes info on it
Size: 98mmX67mmX41mm
Weight: 210g

Have you ever wondered what it would be like to enjoy high-quality music and sound from your mobile device anywhere, even far from home? This way, you can experience music or movies with an immersive feeling. UP1 USB audio interface could help you make it happen.

The portable UP1 audio interface works seamlessly with a single mobile phone or pad. Not only is the UP1 a professional interface that supports 32-bit/192 kHz audio on PCs, but it also supports 32-bit/192 kHz audio on mobile phones.

Equipped with a second USB port for mobile devices (also known as OTG), it provides a new listening experience, allowing users to enjoy 32-bit/192 kHz music directly from their phone or pad. With its pocket-sized design, users can enjoy high-quality music anywhere.
(size:98mm*67mm*41mm，weight:210g)
This feature is also particularly useful for streamers who prefer live streaming using their mobile phones. Even with just a single phone, listeners can experience high-quality audio from streamers, even when the music is played directly from a mobile device.

If streamers want to use their phone for live streaming while using a DAW on their PC to enhance their voice, our Totalmixer is a powerful tool to assist them. It offers four WDM channels and multiple input/output channel for mixing and routing, allowing complete control over input and output channels as needed. Also, Our unique technique enables mobile devices to automatically match a computer’s audio sample rate, eliminating the need for an extra converter for streamers. These makes their workflow more efficient and streamlined.
