Belva BXA6404

Product Highlights:

The Belva BXA6404 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 BXA6404 to be one of the most efficient amplifiers on the market. The BXA6404 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 Belva BXA6404 provides a world-class user control experience. While other amplifiers on the market only feature a variable bass boost switch, the BXA6404 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. Furthermore, the range provided in the BXA6404’s variable bass boost is anywhere from 0 to 18 decibels, whereas in other amplifiers in the same class, the range is only 0 to 12 decibels.

The Belva BXA6404 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 BXA6404 amplifier can also be wired into aftermarket stereos. Equipped with low level speaker inputs, the complicated process of splicing the wire into the stereo can be bypassed by connecting to the RCA inputs which are commonly found in aftermarket stereos. The input flexibility of the BXA6404 means the amplifier is more compatible with a variety of stereos from factory to high-end aftermarket units.
