ProLoop D15 (1300m2)

PROLOOP D15: class-D loop driver for large rooms up to 1.300 m²

The loop amplifier PROLOOP D15 is specially designed for deployment in public and commercial installations. The system is actively protected against short circuits and is notable for its high reliability and safety. The PROLOOP D15 supplies rooms up to 1300 m² with steady inductive audio signals of excellent quality.

The combo-XLR-3 in-port as well as a further phoenix contact are individually configurable:

a) as audio-in (balanced)

b) as microphone-in (unbalanced)

The microphone mode allows the selection of phantom power for the use of condenser microphones.

The Automatic Gain Control (AGC) guarantees a constant field strength, a exemplary high stability in sound volume and good sound reproduction. A monitor port allows a direct connection with further loop amplifiers.
