TX 4 series

The new TX 4 series is the best solution for those sound reinforcement applications requiring a multichannel amplifier with a mid output power density and a ver y good sounding characteristic but on an affordable budget.
Implementing Power Factor Correction ( PFC ) technology along with Universal Mains Regulated SMPS power supply and Class D power modules the TX 4 series combines in the same amplifier all the functional requirements for most sound reinforcement applications.


  • Class D power modules.
  • Power Factor Correction technology and Universal Mains R-SMPS.
  • XLR signal input and SpeakON Nl4.
  • Input sensitivity selector on the back panel (0.775V / 1V / 32dB).
  • Routing mode selector on the back panel (stereo / bridge / parallel).
  • Channel independent protection and clip warning indicators on the front panel.
  • Channel independent power and -5dB/-10dB/-20dB/signal presence indicators on the front panel.
  • Low unit weight.
