Behringer

Behringer drew on his experience to build speakers with performance of this level, and made them lighter (17.7 kg for the B115D) and more powerful: Class-D power amplifiers for maximum power and low distortion efficiency, SMPS technology (Switch Mode Power Supply), high-tech alternative to heavy equipment transformers and massive heat sinks. Thanks to wireless microphone series (sold separately) Behringer Ultralink with ultra-compact 2-channel transmitter, that's enough connect the wireless receiver to the dedicated port on the rear panel to have full access to two channels of natural sound and extremely stable wireless connectivity. The integrated mixer offers the same preamps ultra-low-noise, high-dynamic microphones that have made the BEHRINGER mixers are legendary. Furthermore the two entrances accept any mic / line-level signal.
