Now with mTLS security & monitor ganging

Intelligent sound control
for worship spaces

Zonal automatically monitors SPL across every zone of your venue and adjusts Q-SYS gain in real time, so your team can focus on the service, not the sound board.

Everything you need to keep volume in check

Zonal handles the technical complexity so your AV team doesn't have to monitor gains manually.

Automatic gain control

Zonal continuously reads SPL from your room mics and adjusts Q-SYS gain in real time. Volume stays in range without a human touching the board.

Real-time SPL monitoring

Pi nodes with UMIK-1 calibration mics measure A-weighted SPL every 5 seconds, every zone visible at a glance.

Sanctuary78.2 dB
Lobby71.4 dB

Threshold schedules

Different SPL ceilings for Sunday morning, Sunday evening, and weekday events. The controller switches automatically, no manual intervention.

Q-SYS native

Connects to your existing Core over TCP using JSON-RPC. No hardware changes: control any named gain component.

Multi-zone & gang support

Control the lobby, sanctuary, and kids' wing independently, or gang multiple mics into a single zone for large-room coverage.

Enterprise-grade security

Runs entirely on your LAN. No SPL data ever leaves your building.

  • mTLSevery MQTT connection authenticated both ways
  • RBACrole-based access for every dashboard action
  • LAN-onlyno cloud dependency for live control

Up and running in under an hour

No rack gear. No custom firmware. Just software on hardware you already have.

Install the controller

Download the Windows or Linux installer, or pull the Docker image. First-run wizard sets up your Q-SYS IP and admin credentials.

Add a monitor

Click "Add Monitor" in the dashboard. Download the auto-configured Pi package and run one command over SSH; mics are online in minutes.

Set your limits

Define your SPL ceiling and gain floor/ceiling per zone. Add a schedule for each service time. Zonal does the rest.

The same Sunday, two ways to run it

Most churches don't have a sound problem. They have a consistency problem.

Manual mixing

A volunteer rides the faders

  • Volume complaints reach you after the service ends
  • Every operator mixes a little differently week to week
  • Lobby and kids wing drift while attention is on stage
  • Evening service runs on morning's settings

With Zonal

The controller holds the room

  • Every zone held to its target, all service long
  • The same sound every week, whoever sits at the board
  • All zones measured and corrected every 5 seconds
  • Ceilings switch automatically when the schedule does
