  • Page 4: Introduction

    8 line inputs/outputs, 16 AES/EBU inputs/outputs, and one ADAT 8-channel I/O, plus two powerful headphone outputs. Connect the IOC to your SoundGrid network with a single Ethernet cable. DiGiGrid IOC can be used as your primary audio interface, or as an additional I/O expansion to an existing SoundGrid system.

  • Page 5: Getting Started

    To download IOC software you will need to register your device at www.digigrid.net or www.waves.com. You must know the serial number of your IOC in order to register it, so sign up before you mount it in a rack. The serial number appears on a label on the bottom of the unit or on a sticker on the box.

    3. SUGGESTED USES AND CONFIGURATIONS There are many ways to use your DiGiGrid IOC. Your existing (or future) equipment, how you work, and what you need to accomplish are factors to consider when incorporating an IOC into your studio. Project studios with one or two DAWs can share I/O resources.

    SoundGrid devices. To clock the entire network to an external clock source such as house sync, use Word Clock or Digital In as clock master for the IOC. If the IOC is the SoE master, the entire network will be locked to this external source.

  • Page 11: Adding A Server

    Some DiGiGrid I/O devices are equipped with internal servers. With these devices, the server will appear under the Servers section and the I/O under the Rack A: Hardware I/O Devices section. Configure these I/Os as you would any similar I/O device. All servers initially appear as “SGS.

    DAWs—can be a part of this network, so each computer must have the IOC software installed. Two computers can be connected to the DiGiGrid IOC Ethernet switch via a single Cat 5e or Cat 6 Ethernet cable. If you want to add further computers, you will need to connect them to an approved external 1GB Ethernet switch.

  • Page 13: Hd Mix Room And Several Smaller Recording/Editing Rooms

    In this configuration, you have four control rooms: Room A with a Pro Tools HD system, and Rooms B, C and D each equipped with a DiGiGrid IOC. Each system can operate independently and take control of the IOX placed in the live rooms. In addition, any one system can control any or all of the I/Os: for example, the Pro Tools HD system has access to any or all of the three IOCs.

    4. SOFTWARE SETUP AND CONTROLS A SoundGrid network is managed by the SoundGrid Studio Application. This application assigns and removes devices, oversees the network, patches between devices, and provides access to device control panels. To maintain network effectiveness, the SoundGrid Studio Application always runs in the background.
  • Page 16 In the SoundGrid Studio Setup page, you will see racks containing all of the devices assigned to your system: physical and virtual I/O devices, drivers, and servers. Each I/O rack slot displays the device’s mode, clock status, and sample rate. In this example the IOC is...

  • Page 18: Device Firmware

    4. 1 Device Firmware Firmware is a small program that runs on a device in order to control it. It enables IOC to communicate correctly with SoundGrid Studio. An I/O that is using outdated or incompatible firmware will not work properly in a SoundGrid network until its firmware is updated.

A saved preset includes all Clock and Control panels parameters. Use IOC presets to use on future sessions or copy them to another computer to duplicate a configuration.

  • Page 21: Controls Page

    The Clock and Controls pages are used to set up and manage the IOC. 5. 1 Controls Page This is where you configure the IOC inputs and outputs, including mic preamps, line inputs and outputs, digital I/O, level control and metering.

  • Page 22: Top Bar

    5. 1 . 1 Top Bar The Top Bar of the Controls page includes an illustration of the IOC rear panel. When an input or output is selected in the main section of the page, the corresponding connector is highlighted.
  • Page 23 This allows you to control preamps “on the fly, ” without leaving your monitor mixer. eMotion ST also provides a digital trim for incoming digital signals. Refer to the eMotion ST user guide to learn how to integrate the IOC with the eMotion ST mixer.
  • Page 24 Analog Output Controls In addition to meters and clip and peak indicators—which are identical to the input controls—there is a Headroom switch that provides a -10 dB pad. Presence of the -10 dB pad on an analog output is indicated by a blue light.

  • Page 25: Digital Section

    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.

  • Page 26: Clip Indication And Small Meters

    5. 1 .4 Clip Indication and Small Meters Clip Indication Threshold sets where the clipping is indicated on the meter in the Focus section. This allows you to monitor levels in the way you find most comfortable. The threshold can be set to 0 dB, -1 dB, -2 dB, or -3 dB. This setting is global, not channel-specific. When Clip Indication Threshold is set, this behavior affects level indication for all channels, input and output.

  • Page 29: Adding A Server To The Ioc

    When you connect a server to the host computer and run the SoundGrid Studio Wizard, the server is assigned and configured for the host. Normally that’s all you need to do. The server appears in the SoundGrid Studio Server rack, and the IOC is seen in the Hardware I/O rack.

  • Page 30: Applications Of An External Server

    You can set up and control the IOC preamp from eMotion ST, so you never have to leave the mixer to adjust microphones. For further information, refer to the eMotion ST user guide.

    6. 1 .2 StudioRack StudioRack is a plugin chainer for any DAW. It hosts up to eight plugins, controls them, assigns them to external controllers, and manages them—with their presets—all in a way that makes it easy to move from one DAW session to another and from one DAW platform to another.

  • Page 32: Moving Audio In A Soundgrid Network

    7. MOvING AUDIO IN A SOUNDGRID NETWORK You’ve configured the network and set up the IOC preamps. One last thing to do: Integrate your hosts into the SoundGrid network so that you can send audio to and from devices and listen to it. In order to do this, the audio must be patched from one point to another.

  • Page 33: Using An I/O Device With A Daw

    7. 1 Using an I/O Device with a DAW When using a DAW on a SoundGrid network, the SoundGrid ASIO/Core Audio driver serves as a bridge between DiGiGrid IOC and the DAW. It enables the I/O to communicate with the DAW, and it provides patch points for connections. Using the driver and routing audio through it involves two steps: patch between the I/O and the driver;...

  • Page 34: Patching I/O To Driver And Driver To I/O

    7.2 Patching I/O to Driver and Driver to I/O When streaming audio to and from an IOC and a DAW, you must assign IOC inputs and outputs to the SoundGrid ASIO/Core Audio driver. (Alternatively, you may choose to monitor through the eMotion ST mixer. We’ll cover that option later in this section.) In the SoundGrid Studio Patch page, select the Device-to-Device tab.

  • Page 36 In the Patch page (left), IOC analog channels are patched to driver channels 1–34. The arrow on the upper left of the Patch indicates that signal flows from the IOC to the driver. Now look at the DAW I/O. The 34 driver channels appear at the top, and are patched to DAW input channels 1–34.

    7.3 eMotion ST Mixer Patching The eMotion ST mixer enables you to create studio monitor mixes as well as personalized headphone mixes. Patch to and from the mixer using the eMotion ST input and output tabs on the left side of the interface. The green buttons indicate whether a channel is mono, left side of a stereo pair, or right side of a stereo pair.
