Installation

System Requirements

• Operating System: Windows 10 (build 1903+) or Windows 11
• Runtime: No additional runtime required — MZAP ships as a self-contained Native AOT executable
• Audio: At least one audio output device (DirectSound, WASAPI, or ASIO)
• Disk: ~50 MB for the application
• RAM: 128 MB minimum, more for large media libraries

Download MZAP

Install

1. Run the downloaded installer (MZAP-Setup.exe)
2. Follow the installation wizard
3. Launch MZAP from the Start menu or desktop shortcut

MZAP installs as a standalone desktop application that includes both the audio engine and a built-in web UI.

Network access (LAN)

The installer offers "Allow access from other devices on your network (LAN)", which is ticked by default. It adds Windows Firewall rules allowing inbound connections to MZAP.Api.exe only:

Protocol	Ports	Purpose
TCP	5100–5115	AirPlay RTSP control
UDP	6100–6195	AirPlay RTP audio
UDP	5353	mDNS service discovery

These are required for AirPlay input and for exposing MZAP to the local network. Unticking the option keeps MZAP restricted to this computer — AirPlay input and remote web access will not work in that mode. Your choice is remembered when you upgrade.

If AirPlay is not accepting connections

Re-run the installer and make sure the option is ticked. Without the rules, an AirPlay endpoint is still announced and still appears in the AirPlay list on an iPhone or Mac, but every connection attempt is blocked by Windows Firewall — from the sender it looks like a device that simply refuses to connect, with nothing in the MZAP logs to explain it.

Streaming zones use their own ports and still need a rule added by hand.

First Launch

On a fresh install the window opens centred at 1280×860, sized so the desktop interface (with its sidebar) is used rather than the narrow mobile layout. MZAP declares per-monitor DPI awareness, so window sizes are applied in real pixels — on a 4K display at 150% scaling the window is correctly sized and text and icons render sharply rather than being upscaled by Windows.

Once you have moved or resized the window, your saved position and size are restored on every later launch.

When you launch MZAP for the first time, the application window opens on the Welcome screen — a quick tour of MZAP's main concepts with cards for Devices, Players, Zones, Matrix Routing, Radio Browser, and the Scheduler. A Documentation card at the bottom of the Welcome screen has an Open Documentation button that launches this site in your default browser.

On first launch — and every launch after — MZAP automatically detects and initializes all available audio devices. No manual setup is required to get sound working.

To review your hardware:

1. Navigate to the Devices page
2. You'll see every detected audio device listed, with zones already created — one per channel on each device
3. A Refresh button is available on the Audio Devices screen, but it is not fully implemented yet — for now, restart MZAP if you plug in new hardware and need it picked up

You're now ready to create players and start routing audio. See the Quick Start guide for next steps.

Opening the Documentation

You can open this documentation site from inside the app at any time:

• Help menu → Documentation — opens docs.multizoneaudioplayer.com in your default browser.
• Welcome screen → Open Documentation — same destination, from the Welcome tab's Documentation card.

Updating

MZAP includes a built-in update checker. When a new version is available, you'll see a notification in the application. You can also check for updates manually via Settings > Check for Updates.

Uninstall

Use the standard Windows Apps & Features settings to uninstall MZAP. Application data (workspaces, presets, media library) is stored in %APPDATA%\MZAP\ and is not removed during uninstall — delete this folder manually if you want a clean removal.
