The unique goal of this design is to achieve excellent sound quality, with a continuous sound pressure level greater than 120 dB SPL, from package dimensions of only 178 mm×203 mm×102 mm. In addition, the system must be highly reliable. The technical development of the preamp circuit, signal processor, power amplifier and loudspeaker driver are described below.展开更多
文摘This paper describes the design considerations for a high output, musical instrument amplifier in a small, portable enclosure. The unique goal of this design is to achieve excellent sound quality, with a continuous sound pressure level greater than 120 dB SPL, from package dimensions of only 178 mm×203 mm×102 mm. In addition, the system must be highly reliable. The technical development of the preamp circuit, signal processor, power amplifier and loudspeaker driver are described below.
