  • Page 4: Introduction

    DiGiGrid IOS is an audio interface for native DAWs and Waves SoundGrid applications that run on a SoundGrid network. It has eight mic/line inputs and 8 line outs, along with the standard digital ins and outs. Like all DiGiGrid I/O devices, it can be used by the local host or by a remote audio workstation anywhere on the SoundGrid network.

  • Page 5: Getting Started

    To download IOS software you will need to register your device at www.digigrid.net or www.waves.com. You must know the serial number of your IOS 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.

  • Page 6: Software Installation

    1.3 Software Installation After you register your new IOS, you can download the installer from the Download/Hardware Drivers section of the Waves website. Since SoundGrid enables you to access an I/O device from any computer in the network, you will need to install the software on each computer in the network.

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

  • Page 10: Adding More I/Os To Your System

    Add a DiGiGrid IOX and you pick up another 12 mic inputs, 6 line outs, and 4 more individual headphone outputs. Connect the IOX to the built-in Ethernet switch on the rear of the IOS. You can add up to eight SoundGrid I/O devices to a single host. Each of these can be accessed by any computer on the network.

    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 15 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 IOS is...
  • Page 16 To add another SoundGrid device, click on the arrow in an empty rack slot. From the list of available devices, choose the one you want to add, in this case, a DiGiGrid MGB coaxial MADI interface. In this image the IOS is grayed out, and therefore unavailable, since it is already claimed (in this case, by you).

  • Page 17: Device Firmware

    4. 1 Device Firmware Firmware is a small program that runs on a device in order to control it. It enables IOS 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 IOS presets to use on future sessions or copy them to another computer to duplicate a configuration.

  • Page 20: Controls Page

    The Clock and Controls pages are used to set up and manage the IOS. 5. 1 Controls Page This is where you configure the inputs and outputs of the IOS. Mic preamps, line inputs and outputs, digital I/O, level control and metering: all of the things you’d expect from a top-end I/O.

  • Page 21: Top Bar

    5. 1 . 1 Top Bar The Top Bar of the Controls page includes an illustration of the IOS rear panel. When an input or output is selected in the main section of the page, the corresponding connector is highlighted.
  • Page 22 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 IOS with the eMotion ST mixer.
  • Page 23 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.

    Use the SRC button to enable input sample rate conversion. When SRC is selected, IOS will convert incoming digital stream to the sample rate of the clock that the device is locked to. A yellow light on a channel button indicates that sample rate conversion...

  • Page 25: 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.

    StudioRack channel can be sent to aux tracks or a main mix. You can set up and control the IOS 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.

  • Page 30: Studiorack

    When part of a SoundGrid network with a DSP server (such as DiGiGrid IOS), StudioRack can shift plugin processing away from the local CPU and direct it to the SoundGrid DSP server. StudioRack works in conjunction with the eMotion ST mixer to create numerous personalized monitor mixes that use the same plugins heard in the mix—all with virtually no latency.

    7. MOVING AUDIO IN A SOUNDGRID NETWORK You’ve configured the network and set up the IOS 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 32: 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 IOS 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 33: 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 IOS and a DAW, you must assign IOS 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 34 Selecting the Driver in the DAW DAW I/O Setup When a DAW is part of a SoundGrid network, the When you look at the I/O setup page of your DAW, what you see SoundGrid ASIO/Core Audio driver must be its playback are driver channels, not the channels of the I/Os themselves.
