The DiGiGrid MGB and MGO MADI-to-SoundGrid interfaces are used for connecting
MADI-enabled devices to a Waves SoundGrid network for plugin processing and/or
DAW playback and recording .The MGB unit is equipped with MADI BNC connectors;
MGO is equipped with MADI optical connections.

2. Configurations
The MGO and MGB interfaces may be used in both SoundGrid and Native
configurations, as follows:
•SoundGrid – In a SoundGrid configuration, the MGB or MGO interface is used to
connect a MADI-enabled console to a SoundGrid network, for plugin processing and
simultaneous DAW playback and recording. The SoundGrid configuration uses a
dedicated SoundGrid DSP Server to power the plugin processing, thus enabling
super low-latency, high plugin counts, and networking capabilities, with the option of
an additional backup DSP server.
Please note: A SoundGrid DSP server is required for SoundGrid configurations.

•Native – In a Native configuration, the MGB or MGO interface is used to connect a
MADI-enabled console to the SoundGrid ASIO/Core Audio driver, for plugin
processing and/or DAW playback and recording. Since the Native configuration
utilizes the computer's CPU to power the plugin processing, plugin count and overall
system latency depend on the computer’s CPU and sound driver capabilities.
Please note: A SoundGrid DSP server is not required for Native configurations.

5. Using DiGiGrid MGO or MGB with the Console
•Connect your MGB to the console using BNC MADI cables. Connect your MGO to
the console using optical MADI cables.
•Connect to the SoundGrid network using Cat 5e or Cat 6 cables. Connect the
MGB/MGO interfaces to your computer’s local LAN port, or use two cables to
connect the MGB/MGO and your computer to the SoundGrid-compatible network
switch.

7. MGB/MGO Control Panel
When you launch the DiGiGrid MGB/MGO driver control panel, it will load the Clock tab.
The following settings are available in the Clock Settings window.
•SOURCE sets the clock source.
oInternal – The interface itself provides the clock.
oExternal WC – The interface has a Word Clock Input connector to
connect an external clocking source in order to sync all devices in your
network to the external clock.
oSync-over-Ethernet – Send or receive Word Clock / Sample Rate over an
Ethernet cable between DiGiGrid network devices.
oDigital – Syncs via the BNC or optical MADI connection on MADI Port 1
or Port 2 (selectable). The MGB/MGO interfaces sync to the incoming
MADI from the console.
•SAMPLE RATE sets the sample rate when Clock Source is set to Internal.
Range: 44.1 / 48 / 88.2 / 96 kHz.
•SAMPLE RATE MODE sets the MADI mode for 88.2 / 96 kHz operation; check
your console manual for the proper selection.
Range: High Speed, SMUX.

•STATUS displays synchronization status.
Range: Sync, No Sync
•CURRENT CLOCK SOURCE IS displays the current sync method.
•SOE displays Sync-over-Ethernet status (On or Off).
•CLOCK SOURCE AUTO-SWITCHING allows the MGB/MGO driver to switch
between clock sources if it finds a higher priority source than the currently
selected source. Sync priority order is: SoE, WC, Digital 1, Digital 2, and
Internal.
MADI OPTIONS Tab
One MADI connection supports 56 or 64 in/out channels at 44.1/48 kHz, and 28 or 32
