The Belva BXA15001 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 BXA15001 to be one of the most efficient amplifiers on the market. The BXA15001 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.

While other amplifiers on the market only feature a variable bass boost switch, the BXA15001 is equipped with a variable bass boost knob. This allows the user to fine tune the bass and gain in the amplifiers with more precision. The variable bass boost has a range of 0 to 18 decibels, whereas in other amplifiers in the same class, the range is only 0 to 12 decibels.

The BXA15001 has superior input flexibility features both high level and low level speaker inputs. The high level inputs allow the amplifier to be wired into factory stereos or an aftermarket stereo without low level RCA inputs. The low level speaker inputs means the complicated process of splicing the wire into the stereo can be bypassed.
