Install
Install IDFM on Windows, macOS, or Linux from the Innosonix downloads page, then confirm UDP discovery is allowed on the commissioning PC.
IDFM
IDFM (Innosonix Device and Firmware Manager): discover amplifiers, set IP and hostname, and update firmware before Maxx Control or Maxx Remote.
Categories:
IDFM (Innosonix Device and Firmware Manager) is a desktop Electron app for bringing amplifiers onto a working network plan and keeping firmware current. Use it before Maxx Control or Maxx Remote. That workflow includes micro MAXX and other MAXX amplifiers.
When to use which tool
| Need | Tool |
|---|---|
| Discover amps, set IP / hostname, update firmware | IDFM (this section) |
| One amplifier — DSP, routing, device settings in the browser | Maxx Control (on the device) |
| Many amplifiers — projects, groups, offline planning | Maxx Remote |
Tip
Always finish network and firmware setup in IDFM first. Maxx Remote and Maxx Control assume devices are already reachable on a planned IP.
Download
Get IDFM from the Innosonix downloads page (IDFM tab):
| Platform | Artifact |
|---|---|
| Windows | .exe installer (NSIS) |
| Linux | .AppImage |
| macOS | .dmg (universal) |
Product overview: innosonix.de/software.
Recommended path
- Install IDFM and confirm UDP STATUS.
- Discover devices and set IP (hostname / identify as needed).
- Update firmware if newer images are available.
- Continue with Maxx Control (single amp) or Maxx Remote (multi-amp).
How discovery works
IDFM has two ways to get devices into the list — they are not two equal “discovery protocols”:
| Method | When | How |
|---|---|---|
| UDP broadcast | Same L2 segment / VLAN (preferred) | Broadcast to 255.255.255.255 on UDP 9453. Works even if the amp’s IP is on a different subnet than the PC, so you can still change IP settings. |
| Add by IP / subnet scan | Routed networks where broadcast stops at a router | You add a known IP, or scan a /24 range. IDFM then probes the device over HTTP (device REST API) — and the loader path when needed. |
Routers do not forward UDP broadcast. Across VLANs, use add-by-IP or range scan — see Discover and IP.
Ports (PC ↔ amplifier)
| Traffic | Port / address | Purpose |
|---|---|---|
| UDP 9453 | broadcast 255.255.255.255 | Automatic discovery and UDP-based network config |
| TCP 9454 | amplifier IP | Firmware loader / update path |
| HTTP | amplifier IP (device REST, typically port 80) | Manual add and subnet-scan probe (/rest-api/…) |
Some update paths also use HTTP 8080 on the device for file upload. Allow these in the PC firewall (and between VLANs when you use scan/add).
In this section
| Page | Use when |
|---|---|
| Install | First download, platforms, firewall / UDP status |
| Discover and IP | Find devices, STATIC/DHCP, hostname, identify, routed nets |
| Firmware | Download / import .inx, multi-device update, offline; MAXX² bootloader fallback |
| Troubleshoot | Missing devices, port in use, update failures |
Discover and IP
Use IDFM to find Innosonix amplifiers (UDP discovery or add/scan), then set STATIC-IP or DHCP, hostname, and identify the physical unit.
Firmware
Update amplifier firmware in IDFM: download or import .inx packages and flash one or many devices before Maxx Control or Maxx Remote commissioning.
Troubleshoot
Troubleshoot IDFM when amplifiers are missing, UDP discovery fails across VLANs, or firmware updates do not complete.
