»PROLOOP C«: Inductive loop amplifier for medium sized rooms up to 170 m²
The PROLOOP C loop amplifier is designed for the professional use in medium-sized rooms (up to 170 m²) in private buildings and public facilities, in which particularly high dependability and extremely reliable operation are required.
Thanks to being a 100-percent short-circuit-proof amplifier, with switchable, symmetrical XLR input jacks and an extremely stable output performance, the PROLOOP 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
- 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
