1. Introduction
Thank you for choosing the Cadac audio interface for SoundGrid systems. In order to get the
most out of your product, please take some time to read this user guide. We also suggest that
you become familiar with the Waves support site (www.wavesupport.net), where you will find an
extensive answer base, the latest tech specs, detailed installation guides, software updates, and
current information about licensing and registration.
1.1 About SoundGrid and the Cadac SoundGrid I/O
SoundGrid is a scalable infrastructure that provides a variety of cost-effective, high quality
solutions for recording studios. It can be configured in many ways and with many hardware
possibilities to provide a very flexible work environment. This framework is managed by either
the SoundGrid Studio or the MultiRack SoundGrid application, which configures the
network, assigns and manages I/Os, controllers and servers, and patches audio throughout the
system. Any user, anywhere on the SoundGrid network, has access to any of the network’s I/O
devices. Adding a SoundGrid DSP server enables recording and monitoring with very low
latency and moves processing away from the host computer to the server.
A single Ethernet cable connects all devices in the SoundGrid network.
The Cadac SoundGrid I/O (or card) for CDC consoles enables integration with Waves
SoundGrid systems via a single Ethernet cable, allowing live sound engineers to use the
SoundGrid networking technology for low-latency plugin processing, multitrack recording and
playback, and audio networking.
• Super-low-latency networking platform for processing, playback and recording
• Each Cadac I/O allows 64 channels of bi-directional audio
• Connects via a single Cat 5e or Cat 6 Ethernet cable
• Clock Sync-over-Ethernet for digital splits
• Connects to SoundGrid systems and SoundGrid-compatible devices via a single
Ethernet cable
• Compatible with standard computers and switches

• Redundancy and recovery options
• ASIO/Core Audio drivers for recording and playback
• Works with MultiRack SoundGrid software for setup and control
• Networks with every SoundGrid-enabled device
1.2 Typical Uses
The Cadac SoundGrid I/O can be used in both SoundGrid and Native configurations, as follows:
SoundGrid: In a SoundGrid configuration, the Cadac SoundGrid I/O is used in order to connect
to a SoundGrid network for plugin processing and simultaneous DAW playback/recording. The
SoundGrid configuration uses a dedicated SoundGrid DSP server to power the plugin
processing, 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.

5
Native: In a Native configuration, the Cadac SoundGrid I/O is used in order to connect a
console to the SoundGrid ASIO/Core Audio driver for plugin processing and/or DAW
playback/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.

3. Installation and Configuration Overview
The ASIO/Core Audio drivers and control panel for the Cadac SoundGrid interface are installed
using the Waves Central application, which also installs the SoundGrid driver and the
SoundGrid Studio Application required for DAW recording and playback.
Download Waves Central here: http://www.waves.com/downloads/central
3.1 Installing the Cadac SoundGrid I/O
The Cadac SoundGrid I/O comes pre-installed in CDC consoles. For further instructions, please
refer to your CDC manual.
3.2 Configuring the Cadac SoundGrid I/O in MultiRack SoundGrid
Configure the Cadac SoundGrid I/O in the Inventory window of MultiRack SoundGrid:
1. Launch the MultiRack SoundGrid application.
2. Enter the Preferences window by typing Ctrl+P (Windows) or Cmd+ (Mac), or from the
appropriate application menus.
3. Under Local LAN Port, choose the adapter connected to the SoundGrid network and the
Cadac SoundGrid I/O. Network adapters are displayed as Mac addresses and port names.

9
4. When you select the correct port, the message “SoundGrid Network Found” will appear on
the panel. Close this window.
5. Open the SoundGrid Inventory window from the Audio Menu (F2). The SoundGrid
Inventory window displays all SoundGrid I/O devices connected to your network.
6. Assign SoundGrid drivers in the Assign column. Use consecutive numbers for multiple
devices, with the first unit assigned as number 1.
7. Assign SoundGrid DSP servers in the Assign column. The primary SoundGrid DSP server
will be assigned as number 1. If you are using a redundant SoundGrid DSP server, assign
it as number 2.
8. Assign your Cadac SoundGrid I/O (or I/Os) in the Assign column. Use consecutive
numbers for multiple devices, with the first unit assigned as number 1.
9. ID activates LEDs on the card.
10. Update updates the device’s firmware.
Native Configuration
Please refer to the Waves SoundGrid Studio System User Guide.

3.3 Configuring the Cadac SoundGrid I/O in SoundGrid Studio
This is a quick overview of what you need to know about SoundGrid Studio software to get your
network up to speed. There’s enough here to configure a simple network, assess network
status, and set up your I/O devices. For more complex configurations, please refer to the
SoundGrid and SoundGrid Studio user guides.
3.3.1 Setting up SoundGrid Studio
The SoundGrid Studio Application oversees the SoundGrid network and manages all network
devices. To maintain network effectiveness, the SoundGrid Studio Application is always running
in the background. Bring SoundGrid Studio to the front by clicking on the SoundGrid icon in the
Mac Top Bar or the Windows System Tray.
When SoundGrid Studio opens you will see the System Inventory page.

11
The first time you launch SoundGrid Studio, the Wizard will open. It scans the network,
inventories its assets, and then configures the devices. If the Wizard does not start
automatically, click the START Auto Config button, which is next to the Network Port.
Choose “NEXT” to start automatic configuration. This will take a few moments. Choose
“CANCEL” to configure manually.
If the Wizard cannot locate the requested SoundGrid network devices, this means the devices
might be off or not connected properly. In such a case the Wizard will allow you to rescan the
network or work as a Driver node slaved to another system. For more information please refer
the SoundGrid Studio User Guide.
When configuration is complete, close the window. If there is still a problem, you can configure
your system manually. Use the System Inventory page to assign devices, control the network,
and manage clock. To learn how to use this page, please refer to the user guides for SoundGrid
Studio and StudioRack.

12
The first device added to a rack is designated as the Sync-over-Ethernet clock master and is
placed in the first rack slot.
A populated device slot displays the mode, clock status, and sample rate of the I/O. The clock
master device is indicated by its blue color and the icon text: On, Master Clock, INT (48 kHz).
To add another SoundGrid device, click on the arrow in an empty rack slot. From the list of
available devices, choose the one that you want to add—in this case, a second Cadac
SoundGrid I/O. In this image, Cadac SoundGrid is grayed out (and therefore unavailable) since
it is already claimed.
The new device is visible in the
rack slot. Unless changed by the
user, it remains the clock slave
and is colored green.
Use the same menu to change
the assignment of clock master
from one device to another, or
to remove the device from the
rack slot.

13
Now you know how to assign I/O devices and designate a device as the clock master. Click on
the Gear symbol in the device slot to open the Cadac SoundGrid Control Panel in order to set
up clock details and configure preamps.
3.3.2 Firmware Status and Updates
On the left of the device icon are two buttons:
FW indicates the status of the device’s firmware. The user is given the choice to update it.
Status indications are color-coded:
Gray Compatible firmware
Blue Compatible firmware, but a newer version exists
Red Firmware not compatible and must be updated in order to use
Click on the FW button to launch the Reflasher. This will initiate a
scan of the hardware and then offer options. Do not disconnect
device or turn off computer until you see “Done.”
ID activates LEDs on the card.
