As its name suggests, the AER Cubello is a compact but particularly powerful sound cube that offers singer-songwriters, live performers and living room guitarists sufficient amplification for instruments and vocals. The 80 watt acoustic amplifier provides two channels with separate 2-band tone controls for fine-tuning the sound and an additional 48 V phantom power supply for operating condenser microphones. Thanks to the integrated twin-cone loudspeaker with a diaphragm size of 8 inches, both sound sources can be reproduced with astonishing differentiation. The Cubello also offers the option of playing backing tracks either wired via the aux input or wirelessly via the integrated Bluetooth interface. Last but not least, the AER Cubello has a useful effects section in the form of Reverb and Delay as well as a headphone connection for silent practicing.
