    Pin 2 is »hot« on all XLR’s (IEC and AES standards). Unbalanced Input: If you are connecting unbalanced equipment to the D22, pins 1 and 3 must be tied together in the cable ends away from the D22. (see fig. 1) Unbalanced Output: If the D22’s Outputs are connected to unbalanced equipment pin 3 should not be connected.

    When AES/EBU is selected the D22 will send out its own professional set of status bits, meaning that any incoming ID will be lost. However, in order to take full advantage of the D22’s 24 bit resolution you should select AES/EBU to make sure that the receiving device after the D22 will accept all 24 bits.

  • Page 29: Frequently Asked Questions

    Question: What is the data length of the delay time? Answer: The delay is always a decimal number related to the given delay unit of the D22. It is not posible to change delay unit via the RS-485, so you must set this manually before you send the command lines.

  • Page 30: Optional Master Fader

    Why make a Master Fader? The Master Fader makes it possible to perform a manual fade on the very Output of the D22 enabling you to keep your fade in the Digital domain to ensure perfect tracking of left and right.
