Hotel public areas PA system
Lobby, restaurants, corridors, spa and pool — one background-music system with the ballroom and the fire alarm on speaking terms.

Presets: 4+ · Zoning: Per outlet · Emergency level: +15 dB
The design brief
What the space has to do
A hotel’s public areas run on atmosphere. The lobby, restaurant, bar, corridor, spa and pool each have a different mood and a different operating schedule. The audio system has to support that without a technician on duty at 7 a.m.
The design separates the public-area music system from the ballroom and conference systems, but links them where the hotel needs a combined event. The fire alarm and the emergency paging override both. The operator interface is a small number of presets: morning, lunch, evening, late night, event.
Design checks
| Parameter | Value | Note |
|---|---|---|
| Presets | 4+ | morning, lunch, evening, late night |
| Zoning | Per outlet | local control within a defined range |
| Emergency level | +15 dB | above the local ambient noise |
| Music licensing | Operator | licence remains with the hotel |
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 |
|---|---|---|---|
| Fire alarm interface | Hard-wired trigger per zone or group | Fire contractor / SONTRA interface design | Cause-and-effect matrix |
| Paging console | Desktop console or IP paging station | SONTRA supply / local installer | Zone access and priority |
| Network / IT | Dedicated VLAN, QoS, multicast | Client IT / integrator | Network sign-off |
| Loudspeaker circuits | 100V line per zone / riser | Local contractor / SONTRA schedule | Impedance and tap test |
What usually goes wrong
Three physical problems, not three products
Different moods, one building
The lobby, restaurant and spa need different levels and sources. A single global volume control is not enough.
Operating hours
The music schedule changes through the day. The system should switch automatically and still allow a local override.
Event integration
The ballroom and the public areas may need to share a source or an announcement. The interface should be simple and safe.
The design response
What we change in the system
Zone by outlet
Lobby, all-day dining, specialty restaurant, bar, spa, pool, corridors and meeting pre-function are separate zones.
Scheduled presets
Morning, lunch, evening and late-night presets change the source and level. The hotel can edit the schedule.
Ballroom link
A selectable link lets the ballroom feed the pre-function area or the whole public system for a major event.
Fire override
The fire alarm overrides all music and paging. The evacuation message follows the hotel’s fire strategy.
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 |
|---|---|---|
| Lobby and lounge | Calm background music | Ceiling loudspeakers, low taps |
| Restaurants and bar | Atmosphere and local control | Ceiling / pendant loudspeakers, local volume |
| Corridors and lift lobbies | Even low-level music, paging | Ceiling loudspeakers, low taps |
| Spa, pool and outdoor | Relaxed music, weather resistance | Ceiling / landscape loudspeakers |
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 engineerCan the ballroom and the lobby share music?
Yes, through a selectable link. The ballroom can feed the pre-function area or the whole public system for a major event. The link is controlled from the AV room and should not override the fire alarm.
Can each restaurant choose its own music?
Yes, within the system’s source capacity. Each outlet can have a local source and a local volume control within a defined range. The head end keeps the master level and the fire override.
How do you keep corridors quiet at night?
Use a scheduled preset with a lower level and a limited local range. The loudspeaker taps and the EQ are set so the corridor remains intelligible for paging without carrying into guest rooms.
Do you supply the music content?
No. We supply the playback hardware and the audio path. The hotel is responsible for the music licence and the content, either directly or through a licensed music service.
