Hardware
MultiTuner is housed in a standard 19" 1U rack-mount enclosure. RF signals arrive at the antenna input on the rear panel and are distributed by an internal splitter to the installed receiver modules. Each module contains four independent FM receivers that amplify, demodulate, de-multiplex, and decode their assigned channels, delivering real-time measurements to the onboard processor.
The processor handles all monitoring logic, hosts the web interface, and manages streaming output. Configuration is stored in non-volatile memory (NVRAM), so no reconfiguration is required after a power cycle.
MultiTuner is available in two configurations:
| Model | Receiver Modules | Monitoring Channels |
|---|---|---|
| MT-08 | 2 | 8 |
| MT-16 | 4 | 16 |
Front Panel
| Element | Description |
|---|---|
| Power button | Turns the device on or off |
| Status LED | Green — device is running normally |
| Audio output | 3.5 mm headphone jack for live audio monitoring of any active channel |
The front-panel audio output lets an operator listen to any channel directly. The monitored channel is selected from within the web interface and switches immediately without interrupting other channels. This output is intended for spot-checking — for continuous compliance recording, use the IP streaming functionality.
Rear Panel
| Connector | Type | Description |
|---|---|---|
| Power input | IEC C14 | 100–220 V AC, 50/60 Hz |
| Network | RJ-45 | 10/100 Ethernet — management and streaming share this port |
| Antenna input | See order code | RF input for feeder antenna, 75 Ω |
Antenna Connector
The RF connector type varies by order configuration — common variants include IEC 61169-2 (Type N) and BNC. Refer to your order documentation for the specific connector fitted to your unit.
Warning
Always connect the antenna before powering on the device. Running the receiver modules without an antenna signal may degrade RF sensitivity over time.
Network Port
A single RJ-45 port serves both management and streaming. All web interface access, REST API calls, and UDP transport stream output share this connection. In practice, streaming bandwidth is low enough that it does not compete with management traffic on a standard 100 Mbps link.
