Stereo Processor and Encoder for FM

This is the standard use as an FM audio processor.
The unit is located at the transmitter site and connects via 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 your console.
When the transmitter site is remote from the studio, the processor is installed at the site and receives the program audio (PGM) through a point-to-point link, which can be:
  • RF audio link.
  • 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 processed audio to both USB digital output and MPX outputs.
  • A computer receives the audio via USB for streaming.
Therefore:
  • MPX → FM transmitter.
  • USB → streaming computer.
It is recommended to install remote access software on the computer to facilitate streaming system monitoring.

​
FM Rebroadcast of Incoming Stream

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

Uses as 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:

  • Digital radio stations (HD Radio).
  • High-quality streaming transmission.
  • Audio pre-processing in remote units.
  • Sound reinforcement in small shows or rehearsal rooms.
  • Venues, auditoriums, conferences and background music systems.
In this mode:
  • Peak control maximizes digital range usage, with minimal safety headroom (2-3 dB) to prevent coding overshoots.
  • A soft clipper is coupled to the audio outputs, limiting post-multiband compressor peaks and protecting PA power stages.
  • The combination of AGC and multiband compression maintains uniform and clear sound, independent of input signal variations.
