Mirage 4 Evo

Mirage is an important name in the history of AEV Broadcast audio processors, and the thousands of units operating all over the world testify to the success of this device, for this reason it seemed right to continue this name even with the Digital Evolution.

Mirage 4 Evo, digital audio processor, DSP powered, a complete solution for a modern Radio Broadcast, with all full basical features that the broadcaster need. In addition to the basic functions, we have included some functions that make this product unique and highly performing in the cost range proposed by AEV, with a very competitive price and a hight ratio quality/ price, always in the AEV philosophy: high performance but with low costs strong advanced standard features:

  • Audio input mode: Stereo, Mono, Left only, Right only
  • Balanced audio analog inputs & outputs
  • Digital AES/EBU and optical inputs & outputs
  • Advanced audio level detection with auto-switch of audio source
  • Digital audio process, 24 bit resolution
  • Very low audio latency on audio signal ( 3 ms)
  • 3-bands audio process
