D950 Digital Mixing System
8-14 Technical Specs SW V3.3 Date printed: 03.09.03
8.4.5 TC2 Timecode Reader/Generator
The TC2 timecode reader/generator is a 19"/1U unit. It is equipped
together with the optional AutoTouch
TM
Dynamic Automation. Its main
function is to read external timecode, generate a re-shaped TC output and
house the P2 9-pin controller for simple machine control.
Typical power requirements: 100...240 V, 50/60 Hz, 50 W
TC dropout sensitivity: The TC2 allows TC dropout duration of approx. 1 second before a stop is issued, as op-
posed to the Sony 9-pin interface which allows TC dropout duration of approx. 2 seconds.
8.4.6 D19 MasterSync Generator
The Studer D19 MasterSync generator/distributor is a 19"/1U unit. The
generator part can be slaved to an external video clock, word clock, or
AES/EBU input. Should the external reference signal fail, the generator
automatically switches over to an internal reference with 1 ppm accuracy.
The unit distributes one word clock signal to 6 outputs, and the AES/EBU
input (also AES/EBU frame clock signals) to typically 16 outputs each.
The AES/EBU distribution can be configured as 1 × 16, 2 × 8, or 4 × 4 (or
1 × 8 and 2 × 4 simultaneously) distribution by means of a DIP switch on
the back panel.
The generator can be set to 32 kHz, 44.1 kHz, 44.056 kHz, 48 kHz, and
47.952 kHz. When synchronizing to an external video reference, the
generator rate can be set by means of switches.
One MasterSync generator is supplied with the D950 system as standard.
Two generator/distributor units can optionally be linked together by means
of a redundancy cable. In this case, one unit takes over the supply, the
AES/EBU reference, and the word clock reference of both units, should
the power supply of the other unit fail. Both units are always synchronized
in normal operation, so that no phase shift can occur if one unit fails.
Typical power requirements: 100...240 V, 50/60 Hz, 50 W
