Antonio Jose da Silva Santos de Oliveira was born in Lisbon, Portugal in 1956. Finished high school in Liceu Padre Antonio Vieira in Lisbon, 1973, and got his Electrotechnical Engineering degree from Instituto Superior Tecnico, Lisbon in 1979/1980. He worked on industrial electronics maintenance from 1975 to 1978, in the fields of civil contracting, air conditioning and cable extrusion. In this period, he developed a 600kVA automatic emergency power start system for a concrete mill plant, including the refurbishment of the electrical equipment of the entire mill. From 1978 on, he devotes himself in parallel to the development and manufacturing of sound reinforcement equipment.

Co-founds Acutron Electroacustica in 1983, where he develops his activity as a product designer. Designs more than 50 different audio products since the company started. Among them are the Spanish Telefonica 8-channel DAT based automation system, the RCT1/RCR1 broadcast network control system using digitally-modulated audio carriers, the SNOOP audit system based on RCT1/RCR1 hardware, and the hardware part of the DI824 and DO1616 microprocessor-controlled stage boxes used at Expo'98.

He is accepted as a member of the Audio Engineering Society in 1986. Publishes 7 papers from 1987 to 1993 in both AES Conventions and the Journal of the AES, of which the following are examples:


 * "Transient low-end performance of audio noninverting preamplifiers and power amplifiers", Audio Engineering Society preprint 2469 presented at the 82nd Convention, London 1987 March


 * "A feedforward side-chain limiter/compressor/de-essser with improved flexibility" Journal of the Audio Engineering Society, Volume 37, no. 4, 1989 April


 * "A design method for high audio quality FM multiplex encoders" Journal of the Audio Engineering Society, Volume 40, no. 3, 1992 March


 * "A digitally controlled automation system", Audio Engineering Society preprint 3303 presented at the 92nd Convention, Vienna 1992 March

Published several technology articles in Radio World International magazine.
 * "Anti-aliasing filters for oversampling analog to digital converters" Audio Engineering Society preprint 3303 presented at the 94nd Convention, Berlin 1993 March
