From the point of view of energy saving and portability, it is better to build a tent amplifier. This refers to integrated circuits and triodes. This kind of power amplifier is basically hand-made, with reliable welding, low loss rate, good heat dissipation, small size, simplicity and generosity.

From the sound point of view, the power amplifier of the gallbladder machine is good. This kind of machine has good mute, clear and bright sound and high fidelity, which is the main reason why it consumes a lot of power and is large in size, but it has many pursuers.

According to the demand, choose the appropriate power amplifier. For the convenience of stage acoustics, almost all of them are transistor amplification, with high power and loud sound. Courage is mostly possessed by lovers for appreciation.
