FM Stereo Processor and Coder

This is the typical use as an FM audio processor.
The unit is located at the transmitter site and is connected, via the MPX output, to the main transmitter.
  • The secondary MPX output allows connection to a backup transmitter.
  • The program signal enters through the analog inputs.
Always use the appropriate input (balanced or unbalanced) according to the on-air console.
When the transmitter site is remote from the studio, the processor is installed at the transmitter site and receives the program audio (PGM) via a point-to-point link, which can be:
  • RF audio.
  • Digital audio via fiber optic or UHF.

​
USB Output for External Streaming

Requires the Audimax 362HD/USB model.
The USB connection operates independently from MPX, allowing the same on-air processing to be used for Internet streaming.
  • The processor receives the program signal through analog inputs.
  • Sends the processed audio to both the digital USB output and MPX outputs.
  • A computer receives the audio via USB for streaming purposes.
This configuration provides:
  • MPX → FM transmitter.
  • USB → streaming computer.
It’s recommended to install remote access software on the computer to facilitate monitoring of the streaming system.

​
Incoming Streaming Rebroadcast on FM

This setup also requires the Audimax 362HD/USB model and an external computer.
It is used, for example, in signal repeater stations.
  • An external computer receives the streaming from the main station (via Internet or LAN).
  • It decodes it and sends it in PCM to the processor through the USB connection.
  • The Audimax 362 processes the audio and delivers it to the MPX outputs, which feed the FM transmitter.
It is recommended to install remote access software on the computer for monitoring the streaming encoder.

​
Uses as an Audio Processor (HD Mode)

In HD mode (High Definition), the Audimax 362HD can be used in applications requiring dynamic control or loudness enhancement without FM transmission (MPX disabled; see HD Mode).

​
Application Examples:

  • Radio stations with digital broadcasting (HD Radio).
  • High-quality streaming transmission.
  • Audio pre-processing in mobile field units.
  • Sound reinforcement in small shows or rehearsal rooms.
  • Venues, auditoriums, conferences, and functional music systems.
In this mode:
  • Peak control allows for maximum utilization of the digital range, with a minimal safety margin (2–3 dB) to avoid clipping on encoding overshoots.
  • A soft clipper is coupled to the audio outputs, which limits peaks after the multiband compressor and protects the PA power stages.
  • The combination of AGC and multiband compression maintains a uniform and clear sound, independent of input signal variations.
