CLASSIC PRO / CPX4250 4ch power amplifier

The CPX4250 4ch power amplifier, which has the highest cost performance. Despite being a lighter body than its predecessor, it is equipped with uncompromising parts to achieve top-class powerful sound. In addition to a large toroidal transformer, a large heat sink, and a variable cooling fan, it uses the latest SMD technology that has achieved higher stability and reliability.
