BTM-211R applies Bluetooth technology to the conventional amplifier because Bluetooth, a globally accepted transmission standard, features high connection quality and can therefore overcome the complexity of wireless music streaming, providing consumers with a wireless music solution which is easy to use. BTM-211R can be used with Carol’s BTM-210, which turns a wired microphone into a wireless one. Whether you prefer a clear treble or a solid bass, the independent bass/treble adjustment knob can be adjusted as desired. Besides, all the adjustment knobs are arranged on the front panel of the amplifier to facilitate control and adjustment.
