PUC2. The most dynamic USB Audio Interface.

As a compact two‑channel high-definition audio interface, PUC2 combines simple setup with a clever modular design. It comes with digital connections and in various versions providing you with different analog panels on top. Just the way you need it.

Shaping the world of audio interfaces.

When we launched PUC in 2005, it was the first USB audio interface to comply with the highest professional standards. Designed for plug-and-play operation with all common operating systems, PUC is perfect for replacing conventional insertion cards. Looking at the first PUC, you’ll notice its shape inspired by an ice hockey puck. Hence the name…

PUC2. Family business.

PUC2 combines simple, seamless setup with a clever modular design, providing the flexible ease-of-use you demand with the audio quality you deserve. It delivers the highest available audio standards up to 192kHz at 24-bit with a sensational dynamic range of 105dB. All PUC2 versions are housed in an extruded aluminium case. The aluminum unibody is lighter than most metals, and pretty rigid when compared to plastics. 

Unique modular design. Unlimited options.

Thanks to the modular design each PUC2 version employing different analogue I/O boards internally, and different end panels externally, PUC2 meets different requirements. The computer connection panel features AES3 inputs and outputs on XLRs, along with an USB (B‑type) port and a 3.5mm socket, which is used to configure the zero‑latency monitoring modes. 



"Overall, the PUC family of converters represents good value for money providing well thought out features and delivering good quality audio in each direction in a no nonsense, reliable package (...)."

Hugh Robjohn, Sound on Sound

Real-time quality control. Zero Latency.

Zero Latency Monitoring is a unique feature that allows you to monitor your recording signal in real-time, with no delay. Choose between listening to the input signal, or the return path arriving via USB. For further monitoring convenience, an AUX output lets you connect a pair of headphones for a quick and easy audio signal check.

Options, options, options...

More than just an external sound card, PUC2 is suitable for many different fields of application. It links your audio inputs and outputs to analog or digital mixing consoles, speakers, analog and TDM routers and many more.

Frequently asked questions:

  • How is PUC2 synchronized?

    Whenever no signal is received on the digital input, PUC2 makes use of its internal sample rate. By choosing a value between 32kHz and 192kHz via connected PC or Mac, you can set an internal sample rate.


    As soon as PUC2 receives a digital input signal, PUC2 realizes it and synchronizes. In this case the type of digital input signal determines PUC2's sample rate.


    Because PUC2 is not a sample rate converter, there is no way to configure it to 192kHz via USB and at the same time process a digital signal with 48kHz. This is not possible because PUC2 always adapts to the digital input signal as soon as a digital cable is connected.

  • What is the difference between PUC2 Line for International and for German Levels?

    While PUC2 for German levels gets you 0 dBFS = + 15 dBu (+6 dBu / 9 dB Headroom), PUC2 for International levels equips you with 0 dBFS = + 15 dBu (+4 dBu / 14 dB Headroom).
