Design Considerations for a New Class of Compact and Efficient Musical Instrument Amplifiers

摘要

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.
