The channel flex list

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

BPX Cannel Flex List

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

The flex list 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 flex list.

Changing a channel's destination

MCX Cannel Flex List

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 flex list selection menu that can be navigated by rotating the Encoder. A new channel destination is chosen by clicking the Encoder.

Warning: Please be aware that a channel with Channel Mode: Flex configured can't be muted by simply touching the Touchscreen section. Muting only works by clicking the Encoder while pressing the channel's Touchscreen section.

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

Channel 1 - 32 Function

These functions allow for a quick (re-)adjustment of the visual arrangement on the device without changing the user's configuration through the software.

No Function / Empty Function

This function can be used to completely clear a Button and its Touchscreen section to prevent accidental operation.

Operation mode 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.

Warning: The multicolor buttons normally open a channel for voice communication, regardless of the active operation mode. Toggling between modes will only affect the buttons function if the option Button Mode is set to Mode.

Listen Mode Function This function switches the mode of operation to voice communication.

When active, the Touchscreen section of any assigned channel can be tapped to mute or unmute it. Pressing the Touchscreen and rotating the Encoder adjusts the channel volume.

Tip: Please be aware that this mode enables the talk function for the multicolor buttons, should the option Button Mode be set to Mode.

Call Mode Function This function switches the mode of operation to call signals. When activated the Touchscreen section of any assigned channel can be tapped to send a call signal.

When pressed for more than 3 seconds, an Alarm Call will be sent until the touchscreen section is rereleased.

Listen-Call Mode Function This function serves as a toggle to switch between the communication modes Listen and Call.

The Listen function will be prioritized when (re-)activating the function with the multicolor Button.

Cue Mode Function This function switches the mode of operation to cue signals. When activated the Touchscreen section of any assigned channel can be tapped to initiate a cue signal.

The action that is performed when touching the Touchscreen section can be changed. Normally, an attention cue signal is sent to the selected channel. Tapping the touch screen again progresses the cue phase.

This behavior can be changed to sent direct GO cue signals by pressing the touchscreen section of the function itself. Which mode of the function is currently active is displayed in the function itself:

  1. Cue GO is the normal operation, described above.
  2. Direct GO directly sends a go signal to the selected channel. This skips the attention and ready phase.

Warning: Please be aware that outgoing cues can only be manipulated while the cue mode is active. Outgoing cue signals will still be shown but can't be cleared or progressed when using other operational modes (listen or call).

Communication control

Isolate Function This function mutes all channels that do not have an active talk enabled. Channels will be unmuted as soon as no channel has the talk function enabled.

This function is helpful to control incoming audio in hectic systems. It limits the received audio to active user communications.

Warning: Please be aware that utilizing the Isolate function will cut off all channels except the channels that the user currently talks on. You will only be reachable through call or cue signals on muted channels.

Audio Profile Select Function This function works as a toggle for the two device audio profiles, allowing for a quick switch.

An audio profile contains the configuration for the active input and stores the levels for the available outputs.

Tip: Using the Setup button combination, the configuration for both audio profiles is only a click away.

Answer/Reply Function This function enables the user to answer incomming voice communication. The function will always act as a momentary switch, only allowing for push-to-talk style communications.

The display will either show the linked user or the channel (s) it will reply to.

Depending on the Reply Mode setting's configuration, this function will only reply to the last opened channel or all current ongoing voice transmissions.

Warning: Be aware that this function will stay active after the last received transmission. The delay is configured with the Active Time setting.

Mic Kill Function This function acts as a remote switch, disabling the talk function on all currently active users on a channel.

The Mic Kill function works with groups and users as channel targets.

Warning: Use this function with care, as it can disrupt ongoing user communication.

Cough Mute Function This function allows to temporarily mute the currently active user input.

The microphone will be muted for the duration of the Button or Touchscreen press (momentary).

Channels will keep their talk enabled while the function is active.

Cue Cancel Function This function allows aborting either all or selected outgoing cue signals.

The functions multicolor Button must be pressed together with the Touchscreen section of the channel to abort a selective cue signal.

The Button and Touchscreen section of the function itself must be pressed to abort all currently outgoing cue signals.

Tip: If Button Mode is configured to Mode the Button of a channel can be used to abort a cue signal as well.

Volume control

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

Speaker Volume Function This function allows for quick adjustment of the volume of the internal speaker.

The configured volume is stored in the currently active Audio Profile.

Headset Volume Function This function allows for quick adjustment of the volume of a connected headset.

The configured volume is stored in the currently active Audio Profile.

Line Output Volume This function allows for quick adjustment of the audio level for the XLR3 line output connector on the backside.

The configured volume is stored in the currently active Audio Profile.

Main Volume Function This function is intended to provide status information over the device's current main volume.

This function doesn't need to be used to adjust the main volume!

Direct Channel Volume Function This function allows for quick adjustment of the volume for the special direct channel.

Program Audio Volume Function This function allows for quick adjustment of the volume for the special program audio channel.

Announcements Volume Function This function allows for quick adjustment of the volume for the special announcements channel.

Emergency Volume Function This function allows for quick adjustment of the volume for the special emergency channel.

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.

Warning: The XLR3 line-in and line-out ports generally work with limited functionality when compared to a standard Green-GO audio interface.

While integrations are possible with groups; extended functionality like GPIO control, cue and call signals, etc., are missing when used independently from the user.

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.

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

Driving a relay

Driving An LED

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.

Warning: Please be aware that the resistor between the power supply and pin 4 or 5 is dependent on the voltage of the power supply used!

The setup menu

The setup menu allows local access to almost all settings of the user and device configuration. 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.
