préamplificateur pour microphone à électret

The Consonant is a high-quality audio control amplifier designed to complement the best modern power amplifiers. It offers such refinements as scratch and rumble filters, tone controls with cancel facility and switchable turnover frequencies, and provision for a built-in LED signal level meter. All components, including potentiometers and switches, are mounted on a single p.c. board, thus greatly simplifying wiring. A compatible disc preamp, which may be mounted separately or fixed to the back of the main board, is described in a separate article ( `Preconsonant`).
