Battery powered 3.0 Bluetooth audio system with boombox design that delivers fat beats, great connectivity and a high degree of mobility, plus colourful light effects. With its two 6.5" wide-range speakers, it delivers 18W+2 x 5W RMS of power and frequency response of 70 Hz to 18 kHz. The system plays music from smartphones, laptops or other Bluetooth-enabled device as well as music from micro SD cards and external audio sources via the AUX connection. A separate controller for bass from 'low' to 'high' allows user to adjust the dynamic sound image according to personal preferences. The system also provides two 6.3mm jack inputs for connecting microphones and each of the microphone channels can be amplified with a controllable echo effect - ideal feature for spontaneous vocal performances and karaoke events. FM radio with automatic transmitter search is also provided. With its built-in rechargeable 3600mAh battery, which allows up to 5 hours of music enjoyment, the system is not dependent on any mains operation or battery supply. The battery is easily charged via USB cable on the computer and via USB charger. The striking housing with rubber finish and 4 feet makes it a real eye-catcher, but the system can do even more: booming beats make the speaker illuminate in blue and red, as the music-controlled LED lighting effects provide further entertainment. USB charging cable and audio cable are included. Dimensions: 300 x 280 x 210 mm. Weight: 2.9 kg. Black colour design.
