Contacta V7+

The Contacta V7+ hearing loop driver benefits from a highly efficient Class-D amplifier output stage and an audio subsystem built around an advanced DSP core. 

The powerful CPU in this V7+ induction loop amp ensures peak performance and enables coverage of at least 200m².

  • DSP controlled automatic gain control and high frequency compensation for metal loss
  • Class-D amplifier output stage capable of delivering 5A RMS @ >7V RMS
  • Ultra-efficient power utilisation
  • High pass filter
  • Audio time delay
  • Switchable AGC (Automatic Gain Control)
  • Enhanced loop diagnostics
  • True constant current output stage
  • Simple user interface
  • Backlit LCD display
  • Sleep mode
  • Continuous self-testing
  • Integrated protection circuits with temperature, voltage, short circuit and DC detection
  • Compact half-width 1U chassis - optional MBR-V1 rack mount bracket available
