D19 MicAD NEUE FUNKTION FÜR MICAD MASTER Zum Begrenzen der Anzahl der Fernsteuerkanäle (d.h. der Anzahl der durch den MicAD MASTER gesteuerten Geräte) wurde eine neue Funk- tion implementiert. Bisher mussten zur Wahl des gewünschten Gerätes immer alle 16 Adressen «durchgeblättert» werden, auch wenn nur zwei oder drei Geräte am MicAD MASTER angeschlossen waren.
COME IN! We are happy to welcome you in the steadily growing circle of the Studer D19 MicAD's users, and we felicitate you on your selection.

D19 MicAD [8] LINE/MIC Potentiometer Adjusts the gain of the LINE INPUT (ring) and the MIC INPUT (knob) in 1 dB steps. The printed scale on the front panel corresponds to the LINE INPUT. LINE INPUT, Headroom The LINE potentiometer is calibrated in dBu per full-scale. It repre- sents the dBu value of an analog input signal which causes a full- scale output of the A/D converter.

D19 MicAD 2.4.3 MIDI MIDI controllers can be used via the popular MIDI interface (Musical Instrument Digital Interface). This interface is designed as a 5 mA current loop isolated by opto cou- plers. According to the specifications the cable length should not ex- ceed 15 m.
MIDI IMPLEMENTATION CHART is valid for all kinds of hardware interfaces. The Studer D19 MicAD uses an internal cycle duration of 20 ms; in this time grid all tasks as updating the display, reading in the gain potentiometers, computing the level etc. are fulfilled. During the peri- odical level dump every 20 ms a Sysex message is transmitted.
The message is arranged exactly according to the general MIDI specifications. The Manufacturer ID is defined as 00 00 11 (Studer), MicAD has the Product ID 00. Every message is supplied with a checksum which is the one's com- plement of all data bytes.
D19 MicAD 2.4.4.4 Transmitted MIDI messages The D19 MicAD sends Sysex messages only on request (refer to chap- ter 4.3 of the Appendix). The calculation of the Checksum is performed according to the method explained above in section 2.4.4.3 . System Status is transmitted in the “nibblized data format”, the data correspond to the MicAD's internal status field.
Page 42
D19 MicAD At the Sysex commands “Request Level Status with update” or “Re- quest Sync Status with update” the addressed MicAD sends the re- quested data. For a level dump, e.g., 17 bytes are required. The time consumed (approx. 6 ms) is only a third of the MicAD's cycle time of 20 ms.
D19 MicAD ADDITIONAL INFORMATION What the heck is Noise Shaping? It is often necessary to record on digital media accepting only 16 bit signals. In such cases, the word length of the MicAD's 20 bit convert- ers is best reduced to 16 bit by selecting either then 16NS (Noise shap- ing) or 16DI (Dither) modes.
