DiGiGrid IOC / User Guide

Introduction
Perfect for the control room, the DiGiGrid IOC interface offers a wide range of connectivity options, including two mic/line
inputs with broadcast-grade preamps, eight line inputs/outputs, sixteen AES/EBU inputs/outputs, one ADAT 8-channel
I/O, and two independently adjustable headphone outputs. DiGiGrid IOC can be used as your primary audio interface, or
as an additional I/O expansion to an existing SoundGrid system.
A SoundGrid I/O device is part of a SoundGrid network. SoundGrid is the Waves high-speed networking protocol for
moving audio, clock, and other information between a host system and I/O devices—and between I/O devices
themselves. A SoundGrid host configures the network, assigning servers and I/O devices to mix, process, or record,
depending on the host. SoundGrid I/Os link to the SoundGrid network with standard Ethernet cable.
SoundGrid is scalable. Connect one I/O device to a DAW and you have a high-quality sound card. Add more I/Os and
your system becomes more flexible and powerful. Depending on the host application, a SoundGrid host can assign up to
sixteen I/O devices. Complete SoundGrid systems can be networked together to share devices.
Add a server to a SoundGrid system to offload plugin processing from the host CPU to a SoundGrid DSP server. This
dramatically increases processing power and enables greater plugin counts—it also provides very low system latency.

Getting Started
Configure SoundGrid and assign your devices as follows, however large or small your system.
Connect the hardware
Install the software
Configure your system
CONNECT THE HARDWARE
One I/O
In this example, one DiGiGrid IOC is connected directly to the SoundGrid host computer using a Cat 5e Ethernet cable or
better. This provides plugin processing and/or DAW playback/recording via the SoundGrid ASIO/Core Audio driver.
Host computer with SoundGrid application
SoundGrid I/O device
The host computer’s LAN port that’s connected to the SoundGrid network should be used for SoundGrid only. Do not
share this port with the internet or other networks.
In this configuration, all plugin processing is carried out on the host computer. The speed and power of the host defines
overall latency.

Add I/Os
Adding I/O devices not only increases the number of I/O channels, but lets you have separate devices for stage and
FOH, or live room and control room. Use a "star" network configuration with a 1GB Ethernet switch to connect SoundGrid
devices. Only use switches tested and approved by Waves.
Host computer
I/O devices
1GB Ethernet switch
See this support article for a list of supported switches.
You can connect and assign up to 16 SoundGrid I/O devices to the network, depending on the SoundGrid host
application. All SoundGrid I/O devices, hosts, and servers are connected through the Ethernet switch. You can also add
more computers to enable audio streaming among hosts.
ADD A SERVER
To add a server to your SoundGrid system, just connect it to the Ethernet switch and configure it in your host application.
This moves all DSP processing from the host computer to the server, which provides a higher plugin count and enables
the eMotion LV1 and eMotion ST mixers. Visit the waves.com hardware pages to learn more about SoundGrid servers.
Consult your SoundGrid host application’s user guide to learn about using servers.
Consult your host application user guide to learn how to configure additional I/Os and servers.

Download and Install Software
INSTALLING A NEW SOUNDGRID HOST SYSTEM
Installing the Waves SoundGrid host application will also install applicable device drivers and ASIO/Core Audio drivers.
Your devices will appear in the Inventory of your host system. If a device is not visible in the Inventory, you may need to
install a specific driver from Waves Central—please see below. First, however, check the device’s connections and
power.
ADDING AN I/O DEVICE TO AN EXISTING SOUNDGRID HOST SYSTEM
If you are already using a Waves SoundGrid host application and your device does not appear in the Network Devices
list, use Waves Central to update the host application, which also updates the device drivers—or install just the missing
device driver from Waves Central.1
Waves Central
All Waves software is downloaded and installed via the Waves Central application. To install a specific device
driver, launch Waves Central and follow these steps:
Choose All Products
Search for the driver by name
Choose the driver and click Install
If you are new to Waves products, begin by downloading the Waves Central installer from the Waves Download
Page. See the Waves Central User Guide for instructions on how to install drivers, plugins, and applications.
LICENSES
You do not need a license to use this device. However, many hosts or specific host configurations do require a license.
Refer to your host’s product page for details.

Configure the System
A SoundGrid network is configured and devices are assigned in a host’s Setup window. At the heart of this window are
racks where devices are assigned. Any compatible device that’s part of the host’s SoundGrid network will be available for
assignment. This collection of devices is called the Inventory. Setup is similar with all hosts: identify the host’s LAN port,
select a device slot, and use the drop-down menu to choose an available device.
Please consult the user guide of your host application for specific instructions.
All SoundGrid devices are configured in a similar manner. Throughout this section, we show DiGiGrid IOS as an
example.

Manual Device Configuration
You can assign, remove, and manage a device manually. Click on the plus or arrow
symbol in a device slot to open the Device Menu, then select a device.
Any device not already used will be available for assignment. If no other
devices are assigned, the current device will become your clock master.
Drivers and servers are assigned in the same manner.
See the user guide of your host system for specific instructions on device
assignment and I/O channel patching.
Automatic Device Configuration
Certain SoundGrid hosts—including SoundGrid Studio, eMotion LV1 or SuperRack SoundGrid—offer an Auto-
Config tool. Once your devices are connected and powered up, click Auto to start the configuration.
Auto-Config chooses the correct LAN port on the host computer and scans the SoundGrid network for devices. It then
patches the devices to the host. We recommend that you let Auto-Config take care of things, at least when you are
getting started. If later you add, remove, or swap a device, Auto-Config will reconfigure your inventory and re-patch.
Note that SoundGrid Studio assigns the SoundGrid driver automatically. SuperRack SoundGrid and eMotion LV1 require
that the SoundGrid ASIO/Core Audio driver is assigned manually.

ANALOG SECTION
There are two mic preamps, eight line inputs, and eight line outputs. Select a channel and it will appear in the Focus
section.
Analog Input Controls
An orange light on a channel button indicates that phantom power for that
channel is active. This status is also shown in the Focus section.
Use the Focus section to set preamp levels and turn the 48V phantom on and
off. The long meters range from -80 dBFS to 0 dBFS.
Mic/Line knob gain range: 0 dB to 52.5 dB in 7.5-dB steps
Fine knob digital gain range: 0 dB to 7 dB in 0.5-dB steps
A clip indicator holds for two seconds or for as long as clipping persists.
Peak hold persists until you reset it by clicking on the indicator or switching to
a different input.

Preamp Gain Input Controls analog gain in an assigned I/O device that includes a
controllable preamp.
Input Polarity
Mono channels have one polarity reverse button; stereo channels
have two. Buttons are latching and are colored
green when polarity is reversed.
Digital Input Trim Controls input level from digital sources. Separate
controls for L/R when input is stereo.
This allows you to control preamps “on the fly,” without leaving your monitor mixer. Refer to your host application’s user
guide for details.
ANALOG OUTPUT CONTROLS
In addition to meters and clip and peak indicators—which are identical to those in the input controls—
there is a Headroom switch that provides a -10 dB pad.
A green LED indicates the presence of a -10 dB. pad on the analog output.

Inputs: To gain access to the SRC button, select any of the AES/EBU inputs. Use the SRC button to enable input sample
rate conversion. When SRC is selected, the IOC converts the incoming digital stream to the sample rate of the clock to which
the device is locked. A yellow light on the channel button indicates that sample rate conversion is active for that channel.
DIGITAL SECTION
There are two types of digital inputs/outputs for you to select from: AES/EBU and ADAT.
Upon selection, a higher-resolution meter will appear in the Focus section.
In the AES/EBU section, sample conversion rate (SRC) can be selected independently for inputs
and for outputs.
Inputs and outputs are each divided into two groups: 1-2 and 3-16. Each group is internally linked,
so that changing the sample rate for Input 1 will also change the sample rate for Input 2; changing
the sample rate for Output 3 will change the sample rate for Outputs 4-16.
Outputs: To gain access to the SRC button, select any of the AES/EBU outputs. Once you
select SRC, you can also choose any of the following sample rates: 44.1, 48, 88.2 or 96.

CLIP INDICATION AND SMALL METERS
Clip Indication Threshold sets the level where clipping is shown on the meter in the Focus section. The threshold can be
set to 0 dB, -1 dB, -2 dB, or -3 dB. This setting is global: it affects level indication for all channels, inputs and outputs.
Each channel button—analog or digital, input or output—has a small level meter that indicates
when signal is present and provides a rough idea of level. A red light on the channel button
indicates clipping.

Clock Page
Use the Clock page to set the clock source and sample rate for the device and to assess clock status.
SOURCE sets the requested clock source.
Internal The device itself provides the SEO clock.
External WC Clock is provided by an external device via the Word Clock Input connector.
Sync over Ethernet The device receives clock from the SoundGrid network.
AES/EBU CH1 IOC clocks to an incoming AES/EBU stream

DiGiGrid IOC / User Guide

SAMPLE RATE sets the sample rate when Clock Source is set to Internal. Range: 44.1 / 48 / 88.2 / 96 kHz.
If the device is the network (SOE) clock master, as determined in the Device Racks of the SoundGrid
host, then this setting determines the sample rate of the SoundGrid network.
If Clock Source is set to an external clock source, you cannot change the sample rate from the host.
The Sample Rate menu is grayed out and inoperative.
CLOCK STATUS INDICATORS
Three windows on the right side of the Clock control panel help you to quickly assess the network status of the device.
When the device is a slave in the SoundGrid network, you will likely sync it to the SoundGrid network clock (via SOE).
Even when the device is an SOE slave, you can lock it to an external clock source. For example, if another SoundGrid
I/O device is the SOE master and is locked to a word clock device, you may choose to receive clock from the same
external device over word clock from the master device rather than via network SOE.
In the event that the selected clock source fails, IOC has a series of clock fallback layers, in the following order: WC,
SOE, Internal. If the I/O is clocked to external source and that clock source fails, the device will seek an alternate source
of clock, in this priority: word clock, Digital 1, Digital 2, and then SOE. If this fails, the device will fall back to Internal.
Status Reports the presence or absence of sync between the IOC and the
SoundGrid network.
Current Clock
Source
Displays the current sync method. This may differ from the choice made in the
Source menu.
SOE Indicates whether this IOC is the master or a slave in the SoundGrid network.
This mirrors the status information in the SoundGrid Studio Device Rack
