Other Rednet System Components; Using Rednet Control - Focusrite RedNet 3 User Manual

OTHER REDNET SYSTEM COMPONENTS

The RedNet hardware range includes various types of I/O interface and a PCIe digital audio interface
card which is installed in the system's host computer. All the I/O units can be considered as "Break-
Out" (and/or "Break-In") boxes to/from the network, and all are built in mains-powered, 2U 19"
rackmounting housings. There are also three software items, RedNet Control (see below), Dante
Controller and Dante Virtual Soundcard.

USING REDNET CONTROL

A virtual depiction of RedNet 3 will appear on-screen in RedNet Control when a unit is included in
the active system.
Port activity: Each of the RedNet 3's 32 inputs and 32 outputs has a virtual LED which illuminates
to confirm the presence of an audio signal on that channel. Note that as the maximum number
of channels is reduced at higher sample rates, the number of LEDs which may appear active is
dependent on the sample rate.
ADAT/AES/SPDIF switch: Setting this switch to AES/SPDIF selects the source for Channels 1 to 8 to
be the AES/EBU input connector instead of the first ADAT TOSLINK port. (Channels 1 and 2 may be
alternatively sourced form the S/PDIF input - see Tools menu below). Note that Outputs 1 to 8 are
always available at the AES/EBU connector as well as the ADAT port.
Tools menu
: six options are offered:
• Clock Source – lets the user select the source of clock sync. The options available are:
• Internal – sync is derived from RedNet 3's own internal clock
• ADAT – sync is derived from ADAT input 1
• Word Clock – select this when using an external master clock or when RedNet 3 is to be
locked to some other piece of digital audio equipment outside the RedNet network.
• AES – sync is derived from AES/EBU input signal, Channel 1
• S/PDIF – sync is derived from the S/PDIF input signal
• AES SRC – Sample Rate Conversion is available on each of the four AES/EBU inputs and the
S/PDIF input. Users may select which input(s) have SRC enabled; the source set in the Clock
Source menu (above) will be the target clock for the SRC.
• Word Clock Termination – when set, applies a 75 ohm termination to the Word Clock In
connector. This termination should be enabled unless units are connected using "T-Piece"
connectors.
• S/PDIF On – enabling this option sets Input Channels 1 and 2 to be sourced from the S/PDIF
input instead of the AES/EBU input. Note that the on-screen ADAT/AES/SPDIF switch must be
set to AES/SPDIF for this option to function.
• Preferred Master - allows the user to set the unit to be the system master clock source.
RedNet 3 must be set as preferred master when using an external clock source.
