StuderD21 MasterSync includes a highly accurate internal clock reference (1 ppm). The generator can be synchronized from an external source with a video, a wordclock or an AES/EBU signal. A very accurate professional generator will improve the sound of a digital system as well as its stability and reliability. The generator can be set to 44.056, 44.1, 47.952 or 48 kHz as well as twice and four times these values. It is, for instance, possible to convert a 29.97 fps video signal to a 44.056 or 44.1 kHz sampling rate signal. The Video input is on a BNC socket, termination may be selected with an internal jumper from hi-Z or 75 Ohms. Wordclock inputs/outputs are on BNC sockets, input sensitivity is 1 Vpp. The polarity of three of the Wordclock outputs may be inverted with an internal jumper. AES/EBU inputs/outputs are on 15-pin D-type male connectors. For Wordclock and AES/EBU sync signals the input frequency is displayed by front-panel LEDs. The vital significance of a generator/distributor in a digital system is obvious, redundancy therefore is a must. Either a redundant power supply or a second StuderD21 MasterSync linked for full redundancy – both with optical feedback – can be ordered as options. In case of a malfunction, the supplies as well as the AES/EBU and wordclock signals are taken from the second unit, and a front-panel LED indicates that there is a problem. In order to avoid phase jumps during switchover, both units are continuously synchronized. An optional AES/EBU redundancy input allows monitoring of the AES/EBU inputs and, in case of signal failure, switches over to the four auxiliary AES/EBU inputs. The StuderD21 MasterSync is ideally suited for even the most demanding applications such as control or continuity rooms – it is the backbone of your digital studio which you can rely on.
