In Space CE configurations, the Audio Sources section defines every audio fader in a room. Each fader represents a channel on a DSP, matrix, or other audio device, and renders as a slider on the user interface.
Channels are grouped by the role they play in the room:
- Program Audio — the room’s main level, following the audio of the routed source
- Microphones — individual microphone faders, including ceiling microphones controlled through a DSP
- Auxiliary Audio — additional outputs such as a foyer feed, hearing augmentation, or a recording feed
- Advanced Audio — channels intended for the advanced audio page rather than the main volume page
- Pod Audio — faders belonging to a pod in a divisible or pod based room
Program Audio is required. The remaining groups are optional and not present in every configuration.
Section Options
| Property | Type | Description |
|---|---|---|
| Unique Source Levels | boolean | Remembers a separate level per AV source, so switching source restores that source’s last level |
| Synchronize Ceiling Microphone Mute States | boolean | Muting or unmuting one ceiling microphone applies the same state to all other ceiling microphones in the room |
Common Configuration Properties
All audio channels, in every group, share these common configuration properties.
| Property | Type | Description |
|---|---|---|
| ID | string | Unique identifier for the channel. Other parts of the configuration reference the channel by this value |
| Name | string | UI display name for the fader |
| Type | string | The role this channel serves in the room. See Channel Type |
| Disable | boolean | Whether this fader is disabled for this system |
| Visible | boolean | Whether the fader renders on the user interface. Defaults to true |
| Advanced Control Only | boolean | Restricts the fader to the advanced audio page instead of the main volume page |
| Level | object | Fader position control. See Level |
| Mute | object | Mute control. See Mute |
| Power | object | Channel power control, where the device exposes one. See Power |
| Signal Present | object | Signal detection feedback, where the device reports it. See Signal Present |
Program Audio Properties
Program Audio extends the common configuration.
| Property | Type | Description |
|---|---|---|
| Destination Type | string/enum | The destination type whose routed source this program audio follows. Leave blank to follow all destinations |
Microphone Properties
Microphones extend the common configuration for room linking.
| Property | Type | Description |
|---|---|---|
| Remote Controllable | boolean | Whether another room can control this fader when it is the primary in a room link |
| Remote Name | string | The name shown on the primary room’s interface while it controls this fader. Falls back to Name when blank |
Channel Type
Type labels the role a fader plays in the room, and Space CE passes that label through to the user interface. It allows an interface to treat a fader by its purpose rather than by matching on its name.
The common use is a room with both presenter and audience microphones. Setting Type to Audience on the audience microphone lets the interface offer an audience mode control against that fader, and the label continues to work if the fader is later renamed.
Type is optional. A channel with no Type behaves exactly as it did before, so existing configurations are unaffected.
Level
Level controls the fader position.
| Property | Type | Description |
|---|---|---|
| Device ID | string | Device ID of the audio device that owns this channel |
| Block ID | string | Control block on the device, where the device uses one |
| Channel ID | string | One or more channel identifiers on the device, separated by commas. Names may contain : and ., for example a Q-SYS QRC control such as PGM:Level |
| Minimum | integer | Lowest level, in the device’s native volume range |
| Maximum | integer | Highest level, in the device’s native volume range |
| Default | integer | Level percentage applied on room power on and on an audio reset. Leave blank to leave the level untouched |
Mute
Mute controls the mute button that accompanies the fader.
| Property | Type | Description |
|---|---|---|
| Device ID | string | Device ID of the audio device that owns the mute control |
| Block ID | string | Control block on the device, where the device uses one |
| Channel ID | string | One or more channel identifiers on the device, separated by commas |
| Link to Channel ID | string | Follows the mute state of another channel instead of holding an independent one |
| Unmute When Adjusting Fader | boolean | Moving a muted fader unmutes it automatically |
| Unmute Behaviour | string/enum | Which adjustment unmutes the fader when the option above is enabled. Up or Any. Defaults to Any |
| Startup Action | string/enum | Applied when the room powers on and when audio is reset. Mute, Unmute, or None. Defaults to None |
| Shutdown Action | string/enum | Applied when the room powers off. Mute, Unmute, or None. Defaults to None |
Power
Power applies where the audio device exposes a per-channel power state, such as an amplifier channel.
| Property | Type | Description |
|---|---|---|
| Device ID | string | Device ID of the audio device that owns the power control |
| Block ID | string | Control block on the device, where the device uses one |
| Channel ID | string | One or more channel identifiers on the device, separated by commas |
| Startup Power State | string/enum | Applied when the room powers on. True, False, or None. Defaults to None |
| Shutdown Power State | string/enum | Applied when the room powers off. True, False, or None. Defaults to None |
Signal Present
Where the device reports signal presence, Space CE surfaces it against the channel.
| Property | Type | Description |
|---|---|---|
| Device ID | string | Device ID of the audio device reporting signal presence |
| Block ID | string | Control block on the device, where the device uses one |
| Channel ID | string | One or more channel identifiers on the device, separated by commas |
