It is possible to connect any headset to the XLR4 male connector. The built-in amplifier supports an impedance range from 32 Ω to 600 Ω.

Back panel¶

1 12V DC Barrel Connector

The 12V DC barrel connector serves as the secondary power input and can be used with an optional power supply.

1 D-Sub 9 GPIO Connector

A GPIO D-Sub9 connector serves two in- and outputs for external control interfacing.

1 Neutrik XLR3-Female Line-Input

The balanced XLR3 male line-input connector allows injecting analog audio signals via groups into a Green-GO intercom system.

1 Neutrik XLR3-Male Line-Output

The balanced XLR3 female line-output connector allows extracting analog audio signals from a group to external receivers.

2-Port 10/100 Mbps Neutrik EtherCON Switch

A 2-port 10/100 Mbps network switch with Neutrik EtherCON connectors. The first network port LAN 1 accepts PoE (IEEE 802.3af) and is the primary power input for the device.

The user interface¶

To explain the user interface, you can divide and present it into three main areas: Channel and function control, setup and layer control, and lastly, the audio hardware consisting of the speaker and connectors for a microphone and headset.

Channel and function control¶

The first and most prominent area comprises the three blocks consisting of six Touchscreen sections and six multicolor Buttons.

Each button and corresponding touchscreen section are directly linked and show channel or function information and status.

The button and related touchscreen section's function is freely configurable to accommodate every user or situational need.

Channel display¶

When linked to a channel, the touchscreen section displays the following information:

Channel Status

The red X indicates that the Green-GO Engine can't reach any remote device for the configured channel target.

Channel ID

This shows the ID of the channel. Usually, a user has access to channels 1 through 32.

Display Name

The name or display name of the channel target (user or group).

Channel Color

The channel color is defined by the channel target (user or group).

Channel Volume

The current channel volume level.

Setup and layer control¶

Next are the Setup button, Shift button, and multi-function Encoder. All serve in one way or another the function of configuring the device or user interface.

The Setup button gives direct access to the setup menu. The Shift button's main function is to switch between two operational layers of channel and function control. The multi-function Encoder allows to adjust the volumes, navigate the menus of the device, and more.

Configuring the user interface¶

The MCX rack and MCXD desktop station user interface is highly configurable: Any function or channel can be assigned to any Button and its designated Touchscreen section.

    └──> Button Page 1/2

The channel Flexlist¶

The Flexlist is a new UI concept introduced with Green-GO 5.

The function essentially enables the user to quickly change a channel's communication target to a set of 20 pre-defined destinations (users and groups). This allows comfortable and easy control over more channels on devices with limited or crammed user interfaces.

The Flexlist items can be added and configured either directly in a device's User Settings setup menu or with the help of the software.

The Flexlist is enabled on a per-channel basis by configuring a channel's Channel Mode to Flex. Doing so on multiple channels gives independent access to the same Flexlist.

        └──> CH #
            ├──> ...
            └──> Channel Mode: Flex # (1)!

Changing a channel's destination¶

Changing a channel's destination with the flex by touching the channel's Touchscreen section while the Screen Function is set to Listen.

This brings up the Flexlist selection menu that can be navigated by rotating the Encoder. A new channel destination is chosen by clicking the Encoder.

Functions¶

The MCX rack station comes with a set of useful default functions that can be assigned to any Button and its Touchscreen section.

General functions¶

Screen function switches¶

The MCX rack and MCXD desktop station can be operated in three modes that primarily dictate a Touchscreen section's operation. These functions allow for switching between the three modes of operation: Listen, Call, and Cue.

Communication controls¶

Volume controls¶

These functions generally allow for volume control with the help of the Encoder.

The line in-/out engine¶

The MCX rack station comes with a secondary general purpose Green-GO Engine for the line in- and output that provides independend operation with a limited function set.

The line in- and output can be used to import external audio to a group or export a group to the line output.

Alternatively, the line in- and output can be used for the in- and output of the user's Green-GO Engine.

Line Input¶

The line-input allows for transmitting audio through a group to other users in the system. A simple use case for the analog audio line-input on the back of the device would be external analog program audio that needs to be transmitted to multiple users in the system without the need for a dedicated audio interface.

The audio settings and destination (group) of the audio signal can be configured in the device settings.

Configure the line-input¶

Set the destination¶

To use the line-input to import an external audio source into the Green-GO system, we need to assign a Group that transmits the audio signal.

        └──> Line In
            ├──> Assign: # (1)!
            └──> ...

Level the input signal¶

Next, the input signal should be leveled to a peak value around the 0dB mark using the VU-meter on the right side of the line-in setup menu.

It is highly recommended to disable the Gate Threshold and the Compressor during this process to achieve the best results.

Setup Menu

            └──> ...

Compressor and gate¶

The Compressor can be enabled if the dynamic input signal range is too high and the signal clips regularly.

The Gate Threshold acts as a noise-gate and can be activated to avoid transmitting background noise. Adjust this setting carefully to avoid blocking voice communication.

            └──> Gate Hold # (2)!

Configure the line-in as user input¶

It's possible to use the line input as user audio input. This can be useful to integrate an external microphone or audio source in the user's workflow.

To achieve this, we have to adjust the Source in one of the two available audio profiles. When configured, the input will be routed to the user's input and a potentially configured group.

        ├──> ...
        ├──> Source: Line In # (1)!
        └──> ...

Line output¶

The line output allows to output the communications of a group to an external receiver. A simple use case could be an announcement channel that needs to be transmitted via external speakers to a larger audience.

In addition, the line output can be used to connect a more powerful active speaker as the user's output.

        └──> ...

Configure the line-output¶

The configuration for the line-output can be done in the Device setup menu.

Set the source¶

We need to Assign a group to route its communications to the line-output.

Additionally, we can route the signal of the line-input to the line-output using the Loopback setting.

            ├──> ...
            └──> Loopback # (2)!

Level the output signal¶

Next, the output signal needs to be leveled to a peak value around the 0dB mark using the VU-meter on the right side of the line-out setup menu..

It is highly recommended to disable the Limiter during this process to achieve the best results.

Setup Menu

            ├──> Limiter: Off # (2)!
            └──> ...

Configure the line-out as user output¶

It's possible to route the user's channel mix via the line-output. This can be useful for connecting more powerful speakers or integrating the device into existing setups.

To route the user's channel mix to the line-output, we have to adjust one of the user's audio profiles. The routing can be configured by modifying the property Line Out Level.

The general purpose input/output¶

The rear panel GPIO connector enables external switches to initiate commands on the linked Green-GO Engine and also allows the device to set off external switch-controlled events using conditions such as active, talk, call, cue, etc.

The D-Sub 9 GPIO connector features two inputs and two outputs with the following pin-outs:

Each D-Sub 9 GPIO connector is directly linked to one Green-GO Engine and its associated user.

Pin 1 offers 5 Volts of power with a maximum output current of 200mA.

Pins 6 and 7 offer common general-purpose ground.

General purpose inputs¶

Using the general-purpose inputs, it is possible to trigger local commands on the users Green-GO Engine. Allowing for external control over the users' channels and communication.

The inputs can be set to either Normally Open or Normally Closed. If set to Normally Open, the configured function will be executed whenever the switch is closed. If set to Normally Closed, the configured function will be executed whenever the switch is open.

The inputs actuate with contact to the ground, with a max. +5V open voltage.

Warning: Configure this carefully as it will interrupt ongoing user communication.

GPIO Control

Sends a GPIO Control signal on a defined channel to trigger a remote GPIO integration.

Answer/Reply

Answers incoming communication on any or a defined channel. This function will actuate for as long as the contacts are not in the normal state (momentary).

Tip: Depending on the setting Reply Mode this function either answers the last incomming voice communication or all ongoing voice communications.

Cough Mute

Mutes the currently active user input. This function will actuate for as long as the contacts are not in the normal state (momentary).

General purpose outputs¶

Using the general-purpose outputs, it is possible to trigger and control external devices or relays with a set of functions and or states. Allowing to extend the control outside of the Green-GO network.

The general-purpose output is a floating optocoupler. When activated, it's capable of passing 8mA with a maximum of 50 Volts. It can be used to switch third-party logic inputs directly, a signal-led, or with some extra circuitry drive bigger loads like relays.

As with the inputs, the outputs can be set to either Normally Open or Normally Closed, controlling the configuration's idle state.

Activates as soon as any or one defined channel of the user is manually opened to transmit voice communication. The output actuates for the duration of this state (momentary).

Call

Activates as soon as any or one defined channel receives a call signal. The output actuates once as soon as the state changes (toggle).

Alert Call

Activates as soon as any or one defined channel receives an alert call signal. The output actuates once as soon as the state changes (toggle).

GPIO Control

Activates as soon as any or one defined channel receives an GPIO Control signal. The output actuates once as soon as the state changes (toggle).

Driving an LED¶

A signal LED can be driven directly with one GPIO output, utilizing pin 1 as a 5 Volt power supply.

A series of resistors must be added to the circuit to limit the current to a maximum of 5mA. The resistor needed depends on the LED used.

Your circuit for this application could look like the schematics to the left.

Driving a relay¶

A simple circuit with a transistor is needed to drive an external relay with a current higher than 5mA through a GPIO output.

The schematics to the right can be used as an example.

The setup menu¶

The setup menu allows local access to almost all user and device configuration properties. All changes in the setup menu are done and stored locally on the device but can be easily synced back into the configuration file using the Green-GO Control software. These settings are also persistent on the device unless overwritten.

The setup menu is accessed with the dedicated Setup button. The multi-function Encoder is used to navigate the menu lists:

• The Encoder rotation moves a selection or changes a selected value.
• A click of the Encoder enters submenus and allows to change values.
• A submenu can be exited either with the menu entry Exit or Cancel, and alternatively with the Setup button.

Access to the setup menu can be restricted by configuring the security options of a configuration file or user with the help of the Green-GO Control software. In restrictive security configurations, the user may be asked to enter the Tech Pincode before access is given.

User¶

The User submenu holds settings for user-relevant configuration like:

• The user that is linked to the device.
• The channel configuration.
• Configuration for the four special channels.
• The user's Flexlist.
• General user settings (color, communication settings, etc.).
• Script management.

Select User¶

Available Users¶

This menu lists all available users of the active configuration file.

Channels¶

Channel 1 ‒ 32¶

The following is available for each of the 32 channels.

Assign¶

This menu allows selecting a communication target for the channel. Entering this menu will bring up a pre-filter that provides easy access to the active configuration file's available groups and users.

Listen Override¶

This option allows defining a separate listen source for the channel. The user talks to the primary target assigned but listens to the group defined here.

Listen¶

A channel can be enabled or muted independently from the set channel Level. The Listen state of the channel can be easily toggled on or off without losing the set channel level.

This option may be influenced by the Listen Mode.

Level¶

This option defines the output level for the channel.

Talk Mode¶

The Talk Mode defines how a channel can be activated for vox communications with the talk button.

Priority¶

A channel can be configured with one of three priorities. For example, when a higher priority channel transmits, communication with lower priority can be attenuated (Priority Dim).

Output¶

The Output property allows routing the channel's output to a specific hardware output of the device. This is helpful when using devices with stereo outputs or multiple mono outputs.

Listen Mode¶

The Listen state defines a muted or unmuted channel. The Listen Mode options define if and how the channel's listen state is toggled.

Call Mode¶

This option defines if call signals can be sent and/or received on the channel.

Cue Mode¶

The Cue Mode defines how an incomming cue signal is handled.

Channel Mode¶

The Channel Mode allows for simple automation that enables complex channel configurations. Things like automatic replies and GPIO control can be configured here.

Special Channels¶

Each user has, in addition to the 32 normal channels, four additional special channels.

• The temporary duplex channel for private communications.
• The passive program audio channel.
• The passive annoucements channel.
• The passive emergency channel.

Direct¶

The direct channel is temporary and functions bi-directional.

The channel gets created as soon as any remote user who isn't configured on any of the 32 channels contacts the user linked to this device (voice communication, call signal, cue signal).

Level¶

This option defines the output level for the channel.

Output¶

The Output property allows routing the audio of the channel to a specific hardware output. This is helpful when using devices with stereo outputs or multiple mono outputs.

Priority¶

A channel can be configured with one of three priorities. For example, when a higher priority channel transmits, communication with lower priority can be attenuated (Priority Dim).

Cue Mode¶

The Cue Mode defines how an incomming cue signal is handled.

Program¶

The channel for program audio is passive (listen-only), meaning the user can only receive audio on this channel. The channel receives audio through a group, has independent volume control, and supports dimming when the user receives an audio signal on any of his 32 regular channels.

Assign¶

This menu allows selecting a communication target for the channel. Entering this menu will bring up a pre-filter that provides easy access to the active configuration file's available groups and users.

Level¶

This option defines the output level for the channel.

Dim¶
