The PROLOOP DCCplus is designed for rooms of up to 1000 m² with loop signals and is the ideal solution for events and meeting venues.
We gave the PROLOOP DCCplus a complete overhaul and the revised model for 2015 is better than ever!
Each of the two XLR(F) inputs can be configured as LINE (symmetrical) or as microphone input (asymmetrical).
The equipment provides an output of up to 12 A RMS and guarantees secure audio transmission. The Automatic Gain Control hereby ensures good sound reproduction at constant field strength and high stability.

For standard and low overspill supply

Beyond the standard application the PROLOOP DCCplus is also suitable for the realisation of low overspill loop systems. This requires two PROLOOP DCCplus devices.
