REDNET 6 OPERATION

First Use and Firmware Updates

Your RedNet 6 will require a firmware update when it is first installed and switched on. Firmware
updates are initiated and handled automatically by the RedNet Control application. It is important
that the firmware update procedure is not interrupted, either by switching off the RedNet 6 or the
computer on which RedNet Control is running or disconnecting either from the network.
From time to time Focusrite will release RedNet firmware updates with new versions of RedNet
Control. We recommend keeping all RedNet units up to date with the latest firmware version supplied
with each new version of RedNet Control.

Digital Clocking

RedNet 6 is able to operate across two separate clock domains:
• The RedNet network clock
• The MADI clock
Due to the inclusion of sample rate converters in the product, the two clock domains do not need to
be synchronous so independent clock sources can be used.
Three potential clock sources are possible:
• Network (RedNet 6 can also act as network master clock)
• Word Clock In
• MADI Input
When sample rate conversion is enabled, the clock source of the MADI output and the RedNet 6 can
be selected independently in the RedNet Control application.
When sample rate conversion is disabled, the MADI output will be synchronous with the RedNet
network. In this case, the selection of clock source for the unit is selected under RedNet Clock
Source in the RedNet Control application. If MADI and the Network are to run synchronously, the
following rules must be followed:
• If Network is selected as the clock source, it is important that any device sending a MADI
signal to RedNet 6 is also receiving a word clock signal from the RedNet 6 or another
RedNet unit.
• If Word Clock In is selected as the clock source, any device which is sending a MADI signal
to RedNet 6 must also receive a valid clock signal from the same source as RedNet 6
The RedNet 6 Word Clock Output may be switched via the RedNet Control application to output one
of four clock signals:
• Network Clock
• Network Clock (base rate)
• MADI Input
• Word Clock Input
The RedNet 6 Word Clock input has a software selectable 75 ohm termination selected via the RedNet
Control application.
