Magnetic loop amplifier
- The Proloop C magnetic induction loop amplifier is designed for professional use for rooms up to 170m2.
- PROLOOP C is a magnetic loop amplifier. It will amplify the sound from a sound source (for example sound system, hifi channel) through a magnetic loop.
- The wiring of the magnetic loop is a very important step that may require a study.
