PG2-MADI-F-FX User Guide
The word clock outputs are used for the synchronization of external devices with digital I/Os such as preamps,
controllers and consoles. All connected devices with digital I/Os have to get the word clock from the ProGrid device
with which they exchange digital audio data. The ProGrid network is used to distribute the word clock.
5.6 Video Ports
A video in- and output is integrated for the transmission of composite video signals.
5.7 Ethernet Ports
PG2-MADI-F-FX supports OPTOCORE and SANE Ethernet transport. Two LAN ports enable an Ethernet
communication through the network.
5.8 Power Supply
The device is optionally equipped with two power inputs and power supply units. If one power supply fails, due to
malfunction of the feeding power line or the power supply unit itself, the device will automatically switch over to the
other power supply unit. In order to make the power supply redundant, both power inputs must be connected to the
mains supply, if possible to different phases, power supply systems, or even better, one of them to an uninterrupted
power supply (UPS).
The power supply units operate with mains voltage of 100 ... 240 V and frequency of 50 … 60 Hz. Thus the device
can be used throughout the world without any modifications or transformers.
Be aware that the switched-mode power supplies operate with high voltages! Coming into contact with them
can lead to considerable electric shock that may result in death! To prevent electric shocks do not remove
any covers!
5.9 Transmission Delay
The ProGrid system delay, including the matrix, is fixed to 41,6 µs for all channels. The transport delay per ProGrid
unit (<200 ns) in the network is insignificant. The transmission delay is constant from any point to any point. Overall
delay depends on converters and fiber cable length, with ‘normal’ cable lengths of <700 m delay can also be
considered as marginal.
