Magnetic loop amplifier

Magnetic loop amplifier

The PROLOOP DCCplus is designed for magnetic curls of surfaces up to 1000 m² and proves to be an ideal solution for equipping rooms and large meeting rooms.

One of the two XLR (F) inputs can be configured as a line input (symmetrical) or micro (asymmetric) input.

The device provides a power of 12 A RMS and guarantees a safe audio transmission. On the other hand, the AGC and the compression at the entrance guarantee a good restitution of the sound spectrum by constant magnetic field and a great stability.
