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).
