About: dB Technologies Ready 4 Battery Powered Speaker

After the great success of the Mobile 110 sport speaker, dBTechnologies is introducing Ready 4, a high-performance and versatile speaker that will set a new standard for portable PA systems.

Featured with multiple power supply options (battery/power mains), the new Ready 4 can be used in any situation. The battery ensures several hours of autonomy. An exhausted battery can be quickly replaced with a charged battery through the back removable panel. The speaker can be connected to 220 V or 110 V AC power, thanks to a SMPS with auto-range, or a 15 V power supply via an optional external adapter.

Based on the Black Line series box, the new Ready 4 features a stylish contemporary design that will suit any situation.

An optional Bluetooth board, a MIX OUT output and a bright multi-function OLED display enhance the excellent potential of the new Ready 4, placing it right at the top of its category.
