Unpacking Check the equipment for any transport damage. If the unit is mechanically damaged, if liquids have been spilled or if objects have fallen into the unit, it must not be connected to the AC power outlet, or it must be immediately disconnected by unplugging the power cable.
  • Page 7 Installation / EMC Class I Equipment (Mains Operation) Should the equipment be delivered without a matching mains cable, the latter has to be prepared by a trained person using the attached female plug (IEC 320 / C13 or IEC 320 / C19) with respect to the applicable regulations in your country.
  • Page 8 EMC / Maintenance / ESD • Use a system grounding concept that satisfies the safety requirements (class I equipment must be connected with a protective ground conduc- tor) and that also takes into consideration the EMC require ments. When deciding between radial, surface, or combined grounding, the advantages and disadvantages should be carefully evaluated in each case.
  • Page 9 ESD / Repair • When performing a repair by replacing complete assemblies, the removed assembly must be sent back to the supplier in the same packing material in which the replacement assembly was shipped. If this should not be the case, any claim for a possible refund will be null and void. • Unpacked ESD sensitive components should only be handled in ESD protected areas (EPA, e.g.

  • Page 21: Introduction

    D21m System INTrOdUCTION The D21m I/O system provides very cost-effective inputs and outputs with maximum flexibility while maintaining the well-known Studer sound quality. It is the first Studer I/O system providing full 96 kHz operation. Different I/O modules can be plugged into a frame, providing I/O systems tailor-made to customer needs.

  • Page 22: The Frame And Its Cards

    D21m System play it within the console’s system surveyor page. This is without sacrificing any audio channels within the MADI link. Additionally, an RS422 signal can be ‘tunneled’ through the MADI connection. In this way e.g. a MIDI device can be connected to the remote I/O box and find the ‘extension’ connector on the hub frame next to the core again.

  • Page 23: Hub Frame

    D21m System The frame hosts one or two ‘High Density Link’ cards (short: HD Link), providing the main audio connection to the DSP core. From the HD card(s) the signals are redirected to the different types of I/O cards in the frame. Therefore at least one HD card must be inserted in the frame.
  • Page 24 D21m System for the current production). In both cases the surveyor application indicates ‘green’, unless the user tells it to wait for the missing I/O components. There is no need to tell the system which channel has a microphone preampli- fier included, since this detection is done automatically.

The channel count of the MADI link may be set in steps of eight channels using card-internal DIP switches.

  • Page 32: Special Case: Microphone/Line Input Card

    D21m System Special Case: Microphone/line Input Card The smallest modularity of channels used up within the MADI and Core link is eight. If an odd number of Mic/Line input cards is used, they should be inserted in pairs, with the last card in an odd slot (no. 1, 3, 5...) This single card will allocate 8 channels but only 4 of them will have audio.

  • Page 33: 96 Khz Operation

    D21m System 96 kHz Operation D21m Frame The D21m I/O system is fully supporting 96 kHz operation. For digital for- mats, the following standards are supported: AES/EBU 2 channels are sent over one cable, both at 48 kHz and 96 kHz, just by dou- bling the clock frequency of the transmitted signal in 96 kHz operation.

    D21m System Input/Output delays Different DSP core types as well as the different I/O cards cause different delays. Several facts require additional consideration.

    D21m System Standalone d21m I/O System Previously only available for Studer digital mixing consoles, the D21m I/O system is now opened up for use with any audio equipment. With the intro- duction of the D21m remote control software, the microphone amps and A/D converters become available to a wide range of applications, such as record- ing, broadcast, and live sound.
  • Page 37 D21m System The frame acts as a clock slave and synchronizes to the optical MADI signal. It therefore automatically detects the clock rate of the connected audio device. Supported clock rates are 44.1, 48, 88.2, and 96 kHz. In 44.1 and 48 kHz mode the two MADI interfaces work in parallel. One of them may be used as a digital split output or for redundancy.

  • Page 38: Connection To The Performa Core

    D21m System Connection to the Performa Core The Performa core is connected to the D21m I/O System in a similar way as the SCore. The main difference is that the HD link connection from the core towards the D21m I/O frame only carries up to 48 channels (at both 48 and 96 kHz).
