Convention centres & multi-purpose halls sound system
Dividable halls, large audiences and a technical team that needs the room to reconfigure quickly.

The design brief
What the space has to do
A convention centre is a building full of rooms that can be combined, divided and re-purposed. The audio system has to follow the partition state: one hall, two halls or four meeting rooms. The operator needs a clear configuration selector, not a software puzzle.
The design uses separate loudspeaker zones per partition, DSP presets per configuration, and a control interface that shows the room layout. The main hall may use a line array and delay; the breakout rooms use ceiling or wall loudspeakers. The paging and evacuation system follows the fire strategy for each configuration.
Design checks
| Parameter | Value | Note |
|---|---|---|
| Partitions | Preset per state | zone group and DSP |
| Main hall | Long throw | array plus delay |
| Breakout | Local control | independent operation |
| Evacuation | Per configuration | fire strategy updated |
Interface & responsibility
What has to be agreed before installation
The acoustic design is only half the job. These interfaces decide whether the system can be installed, tested and accepted.
| Interface | Typical arrangement | Who provides | Confirm |
|---|---|---|---|
| Stage / rigging | Array and monitor positions | Local rigger / SONTRA design | Load and height |
| Power distribution | Amplifier and lighting load | Electrical contractor | Capacity and phases |
| AV control | Presets and operator panel | SONTRA / venue AV team | Operator training |
| Event operation | Wireless and playback | Venue AV team | Operating procedure |
What usually goes wrong
Three physical problems, not three products
Partition states
Each combination of halls needs its own loudspeaker zones and DSP preset. The control system has to prevent a wrong combination.
Large audience
The main hall needs long-throw coverage and delay. The breakout rooms need speech intelligibility at a smaller scale.
Technical team turnover
The venue AV team changes with events. The system has to be documented and easy to hand over.
The design response
What we change in the system
Zone per partition
Each hall and each breakout room is a separate zone. The partition state selects the zone group and the DSP preset.
Main hall array
A line array or a central cluster covers the main hall. Delay loudspeakers cover the rear and the balcony.
Breakout rooms
Ceiling or wall loudspeakers with local control and a simple input panel. Each room can run independently.
Evacuation per configuration
The fire strategy may change when the halls are combined. The evacuation zones and messages follow the partition state.
Zone schedule
A starting point for the zoning
The final zone list follows the building’s operation and fire compartments. This is the typical structure.
| Zone | Need | Typical kit |
|---|---|---|
| Main hall | Long throw, music and speech | Line array, delay, subwoofers |
| Divided halls | Independent or combined audio | Separate zones, DSP presets |
| Breakout rooms | Speech and presentation | Ceiling loudspeakers, local input |
| Registration / foyer | Background and paging | Ceiling loudspeakers, separate zone |
Equipment families
The blocks used in this design
These are the families that usually make up the system. The final model list follows the zone schedule and the certification route.

Frequently asked questions
The questions that usually decide the scope: loudspeaker count, amplifier size, fire interface, certification and who installs the system. If your question is not here, send it with the building data.
Ask an application engineerHow do you handle divisible halls?
Each partition state gets its own loudspeaker zones and DSP preset. The control system selects the state and prevents conflicting combinations. The fire strategy is updated for each configuration.
Can the breakout rooms run independently?
Yes. Each room has its own local input, volume control and loudspeaker zone. The central system can override for paging and evacuation.
What about delay loudspeakers?
They are used in the main hall where the throw is long or there is a balcony. The delay time and level are set during commissioning so the sound image stays at the stage.
How is the system documented?
The handover includes the zone schedule, the DSP presets, the signal flow, the control interface and the operating procedure. The venue AV team is trained on the configuration selector and the emergency procedure.
