Setups without the software

It's possible to use and configure your Green-GO system without using the Green-GO Control software. Each device provides access to all settings through the local setup menu.

The configuration software provides a single point of which to access and amend your system. Small changes or simple setups can be set up via the device or devices themselves.

Tip: How to access the setup menu on your device is described here.

Configure the network

If you are not familiar with networks or running a dedicated Green-GO only network, you may not need to configure your IP settings. As by default devices are set to dynamic addressing. If no DHCP server is on the network, devices will automatically configure themselves using the link-local address space 169.254.0.0/16 (RFC 3927).

The dynamic addressing may still be suitable for more complex systems. However, it's generally advised to either use a DHCP server or manually configure the network for such systems.

Warning: Please make sure to configure the same subnet mask on all devices when manually configuring your network!

Setup Menu Guide

          ├──> Subnet Mask # (2)
          └──> Gateway # (3)
  1. Defines the device's IPv4 address.
  2. Defines the local subnet for the device.
  3. Defines a local network gateway.

Load a configuration file

As Green-GO doesn't have a central processing unit (e.g., a matrix) that controls each device, every device needs to be a member of the same configuration. Otherwise, communication isn't possible!

All devices come with a default configuration that allows you to use your system with a set of generic groups and user names.

Alternatively, custom configurations can be side-loaded from other devices on the local network.

Load the factory default configuration

The factory default configuration file can be loaded at any time through the Config menu.

Setup Menu Guide
Setup Menu
└──> Config
     ├──> ...
     └──>  Factory Default # (1)
  1. Load the factory default configuration.

Load a custom configuration file

Tip: A custom configuration can be created using the Green-GO Control software.

The menu Join Config provides access to all active configurations on the local network and lists them if they differ from the current one.

Confirming any entry will load and join the configuration selected.

Notice: After loading a configuration, the device will not assign a user automatically. Communication will only be possible after assigning a user.

Setup Menu Guide
Setup Menu
└──> Config
     └──> Join Config
          └──> Configuration Name # (1)
  1. This menu displays other configurations found on the network. Clicking on a configuration name will load the configuration onto the device.

Select a user

After loading a configuration, we need to assign a user to the device to ensure that the correct channel assignments and settings are loaded. You can assign the user in the Set User menu.

Assigning a user will load and possibly overwrite the following settings:

  • Channel assignments and settings.
  • User settings (color, communication settings, rooms, special channels, flex lists & security settings).
  • Device settings (defined by device profiles).
Setup Menu Guide
Setup Menu
└──> User
     └──> Set User
          └──> User Name # (1)
  1. This menu lists all users of the currently active configuration file. Clicking on a user will load its settings onto the device.

Channel assignments & configuration

The Green-GO Engine allows for a complex channel configuration on a per-channel basis. The setup menu Channels gives access to all channels and their settings; this allows to adjust the user's channel assignments and many other options.

Please check out the device documentation or the software documentation for a full overview describing each setup option.

Configure a private user to user communication

Configuring a private one-to-one conversation on a channel requires to assign a user to that channel. This is done on the device choosing the User pre-filter in the Assign setup menu:

Setup Menu Guide
Setup Menu
└──> User
     └──> Channels
        └──> Assign # (1)
            ├──> ...
            └──> User # (2)
                └──> Username
  1. Assigns either a user or group to the channel.
  2. Pre-filter allowing to either select groups, users. Alternatively a channel assignment can be cleared by selecting None.

Configure a group communication

A group communication is configured by assigning a group to a channel. This is done on the device using the Group pre-filter in the Assign setup menu:

Setup Menu Guide
Setup Menu
└──> User
     └──> Channels
        └──> Assign # (1)
            ├──> ...
            └──> Group # (2)
                └──> Groupname
  1. Assigns either a user or group to the channel.
  2. Pre-filter allowing to either select groups, users. Alternatively, a channel assignment can be cleared by selecting None.

Configure the program audio

The Green-GO Engine transmits the program audio with a separate, special channel. The source for the program audio channel is always a group that can be configured in the Special Channels menu.

The program audio volume can be controlled separately and optionally automatically dimmed when an active VOX communication is received.

Setup Menu Guide
Setup Menu
└──> User
     └──> Special Channels
          └──> Program Audio
               ├──> Source # (1)
               ├──> Volume # (2)
               └──> Dim # (3)
  1. Defines a group as a source for the program audio channel.
  2. Sets the loudness of the program audio in the user's channel mix.
  3. Allows setting an automatic attenuation for the program audio when active communication is received.

The audio setup

The audio setup is crucial for every optimal intercom experience. The Green-GO Engine provides the user with many tools to combat challenging environments and allow for clear and low latency voice communication, but configuring these tools correctly is essential.

Set the input source

First, the correct input for the user's voice communication needs to be selected.

In the case of electret or condenser microphones, power must be supplied to the microphone. Green-GO devices support up to 2.5 V via the XLR4 headphone connector and up to 10 V for the XLR3 microphone connector.

Setup Menu Guide
Setup Menu
└──> Audio
     └──> Profile (n)
          ├──> ...
          ├──> Source # (1)
          ├──> Headset Bias # (2)
          ├──> Mic Power # (3)
          └──> ...
  1. Selects the input source for the user's voice input.
  2. Supplies up to 2.5 V of power to the XLR4 headset connector.
  3. Supplies up to 10 V of power to the XLR3 microphone connector. (This setting is only available when applicable.)

Level the input

Tip: Make sure to disable the Compressor and Gate Threshold for optimal results!

Audio Setup Menu Next, this input needs to be leveled to avoid any clipping or distortion. Position the microphone adequately close in front of the mouth and speak with proper volume.

Now adjust the gain so that the VU-meter peaks around the 0 dB mark. Avoiding the red zone makes sure your audio doesn't distort.

Setup Menu Guide
Setup Menu
└──> Audio
    └──> Profile (n)
        ├──> ...
        ├──> Gain # (1)
        ├──> Compressor: Off # (2)
        ├──> Gate Threshold: Off # (3)
        └──> ...
  1. Defines the input gain of the signal.
  2. Disable the compressor when leveling the input signal.
  3. Disable the noise gate when leveling the input signal.

Configure a compressor

The Green-GO Engine features a simple Compressor that can be enabled to reduce the dynamic range of the input signal by attenuating the louder parts of the signal, making it less likely to transmit distorted audio.

If enabled, the release timings of the compressor can be adjusted.

Setup Menu Guide
Setup Menu
└──> Audio
    └──> Profile (n)
        ├──> ...
        ├──> Compressor # (1)
        └──> ...
  1. Enable and configure the release timing of a compressor on the input signal.

Configure a gate

The Green-GO Engine features a simple noise-gate that can be activated to avoid transmitting unwanted background noise, allowing for a quiet and calm intercom system.

The Gate Threshold defines the threshold for the noise-gate to open the microphone. Audio signals below the configured threshold will be cut out and not transmitted. The setting Gate Hold defines the hold time after which the noise-gate closes again after being activated.

Adjust this setting carefully to avoid blocking voice communication

A correctly configured gate will only open the microphone when the user is talking and disable the microphone when the user stops speaking. A poorly configured noise-gate may lead to a stuttering audio signal being transmitted.

Setup Menu Guide

└──> Audio
    └──> Profile (n)

        ├──> Gate Threshold # (1)
        ├──> Gate Hold # (2)
        └──> ...
  1. Configure the input threshold for the noise-gate.
  2. Configure the hold timings of the noise-gate.

Configure the sidetone

The sidetone can function as confidence feedback for the user: The user can hear its voice in the headset and knows when a channel's talk function is enabled.

The setting Sidetone configures the amount of the user's input fed back into its headset output(s). When activated, the sidetone is never routed to a device's front speaker to prevent signal feedback.

Setup Menu Guide
Setup Menu
└──> Audio
    └──> Profile (n)
        ├──> Sidetone # (1)
        └──> ...
  1. Configure the loudness of the sidetone on all active outputs.

Configure the output(s)

Every Green-GO user station has at least one output that can be used to transmit the user's channel mix. The Green-GO Engine allows configuring the loudness of each available output individually.

For devices with built-in front speakers, the output can be attenuated automatically when the user activates a channel talk to prevent signal feedback when speaking.

In addition, the Green-GO Engine provides a global output limiter that attenuates very loud audio signals on the user's output(s).
