ProLoop D5 (300m2)

PROLOOP D5: class-D loop driver for supplying rooms of up to 300 m² with inductive audio signals

Highly reliable, resistant against short circuits and with great audio quality: The »PROLOOP D5« provides middle-sized rooms with stable inductive signals. Comfortable controls enable the user to take full benefit of the versatility this system offers regarding its use in various rooms and deployment conditions.

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

a) as audio-in (balanced)

b) as microphone-in (unbalanced)

A 12-V phantom power feed can be activated for the supply 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 in master-salve configurations etc.
