ABSTRACT
This project is titled the designing and construction of a 200w bass guiter power amplifier. Bass power amplifier is an electronic amplifier is used for increasing the power of a bass guitar signal. Bass power amplifier is used for the bass guitar, double bass and similar instruments, is distinct from other types of amplification systems due to the particular challenges associated with low-frequency sound reproduction.
Bass power amplifier composes of the loudspeakers, the speaker cabinet and the preamplifier and amplifier. Speaker cabinets for bass instrument amplification usually incorporate larger (or more) loudspeakers than those used for the amplification of other instruments. The loudspeakers themselves must also be sturdier to handle the higher power levels.
Bass instrument speaker cabinets are typically more rigidly constructed and heavily braced than those for non-bass instrument amplification. They usually include tuned bass reflex ports or vents for increased efficiency at low frequencies. Preamplifier sections have equalization controls that are designed for the deeper frequency range of bass instruments, and can extend down to 40 Hz or below. Bass instrument power amplifiers are more likely to be designed with cooling fans than regular guitar amplifiers, due to the high power demands of bass instrument amplification. They are also more commonly equipped with limiter circuitry to prevent overloading the power amplifier and to protect the speakers from damage.
