Loop amplifier Pro Loop NX3

The Pro Loop NX3 loop amplifier, like all amplifiers in the NX series, is designed primarily for continuous use. The integrated switched-mode power supply and the Class-D amplifier design enable high efficiency with low waste heat and forms the basis for high reliability and operational safety.

  • Automatic Gain Control (AGC) ensures a consistent level on the induction loop
  • Metal Loss Correction (MLC) can be used to correct the frequency response due to metal structures in the vicinity.
