ALL IN ONE Bus Amplifier

Bus Vox 24 IBV



  • Universal Amplifier- direct open protocol inputs for automatic Pre-
        programmed voice messages systems.
  • Single smart Amplifier provide solution for automatic Pre-programmed
        announcements (inside & outside), microphones (driver & guide), and
        additional infotainment systems (Radio, DVD, LCD).
  • Additional and Separated input for VOIP announcements.
  • Multiple microphone inputs jacks (driver and guide) with priority for the
  • Additional input for a DVD or any other audio source.
  • Superb sound quality.
  • Direct Operating voltage- 24V/12V (without converter).
  • Output power- 4 x 35W.
  • Quick and simple handling and installation.


The GYM 24IBV is an ALL IN ONE system which combines all of the bus amplification requirements into a single amplifier:


-     Next stop automatic Pre-programmed announcements

-     Microphones (Driver + Guide)

-     Infotainment (Radio, DVD, LCD).


The GYM 24IBV enables fast and easy connection to all kinds of fleet management systems or any other application which generates Pre-programmed voice messages systems according to GPS location.


In addition, the amplifier can interface to the on board A.V equipment such as Microphones, DVD, Radio, and LCD.


The Amplifier open interface architecture and protocols makes it easy to interface with other existing infotainment equipment (Radio, DVD, LCD).
