Induction loop amplifier Pro Loop C

The Pro Loop amplifier family is designed for professional use in private and public facilities where particularly high reliability with extremely safe operation is required. 

Thanks to being a 100-percent short-circuit-proof amplifier, with switchable, symmetrical XLR input jacks and an extremely stable output performance, the Pro Loop C is able to meet such demands.

Automatic Gain Control (AGC) guarantees consistent field strength and produces steady sound with a special emphasis on clear speech, even under acoustically challenging conditions.

Corresponding test equipment can be used to evaluate the sound quality via the integrated monitor out jack.

  • High output current: 4.8 A RMS
  • Short-circuit-proof
  • Automatic fuse reset
  • Two symmetrical XLR input jacks
  • One RCA input jack
  • One line-out jack
  • Extra-sturdy jacks
  • Dual action AGC for excellent speech recognition
  • Very reliable, with assured quality
  • Easy monitoring of the magnetic field by using headphones or speakers
  • Treble control the compensation of treble loss due to metal reinforcement in walls
