The Belva BXA5002 is categorized as a Class A/B amplifier. This class of amplifiers combine the high efficiency of a class A amplifier and lower distortion found in class B amplifiers. The class AB amplifier acts more similarly to a class A amplifier by biasing both transistors so they become active when the signal is close to zero. As the signal excursion increases into a larger waveform, only one transistor remains active, a primary function found in class B amplifiers. These features combined with the MOSFET transistor allow the Belva BXA5002 to be one of the most efficient amplifiers on the market. The BXA5002 also features three-way protection circuitry which protects against thermal, overload, and speaker shortages. This configuration increases the longevity of both the amplifier and entire speaker system.

The BXA5002 provides a world-class user control experience. While other amplifiers on the market only feature a variable bass boost switch, the BXA5002 is equipped with a variable bass boost knob allowing the user to fine tune the bass and gain with more precision. The range provided in the variable bass boost is 0 to 18 decibels, whereas amplifiers in the same class range from 0 to 12 decibels.

The Belva BXA5002 features input flexibility with both high level and low level speaker inputs. The high level inputs allow the amplifier to be wired into factory stereos. The amplifier can also be wired into aftermarket stereos. The low level speaker input means the complicated process of splicing the wire into the stereo can be bypassed.
