departure of the Scandalli family from the company. However, Farfisa has survived into the 21st century, and brand mainly produces intercom systems with the company ACI Farfisa which makes and distributes systems for video intercoms, access control, video surveillance, and home automation. The Bontempi group owns the rights for Farfisa keyboards. Models Compact Series (1964–1969) The Compact series contains four models – Combo Compact, Mini Compact, Compact Deluxe and Compact Duo. They have 12 tone generator boards; one for each note of the scale, and use a frequency divider to generate the remaining notes. Unlike later organs, the Compact series is not fully transistorised, and includes high-voltage tube circuitry for the reverb unit. On most single-manual models the tone controls and a bass section volume are located on an indented panel on the rear of the instrument. Underneath the keyboards, there is a knee-high lever that can be actuated for tone boost, turned on by rocker levers on the console. The series features a photoresistor-driven swell pedal, instead of the later and more common potentiometer. There are two jack outputs, the second of which is optional and can be used to send the bass through a different amplifier. There is also a headphone output jack, but it designed for now-obsolete 2000 ohm-impedance headphones. Though advertised as a "transistorised" model, the spring reverb tank is valve-driven. An optional 13-note bass pedalboard can be added to all models except the Mini-Compact. Unlike other combo organs like the Vox Continental, Farfisa Compact organs have integrated legs, which can be folded up and stored inside its base. The Combo Compact has a five-octave keyboard, one of which of bass with inverse key colors, 16' bass and strings, 8' flute, oboe, trumpet and strings, 4' flute, piccolo and strings, four vibrato settings, three choices of reverb and three bass volume switches. It has a built-in spring reverb system. The Mini Compact is the smallest of the Compact Series, and was introduced in 1966. It has only four octaves, with no bass on the early models. The later version has a selector switch to choose bass or high sound in the lowest octave; these models have grey naturals with white sharps in the bass octave. Some of these extended bass models have only three voices (sounds), while the later models had six voices. Early compact models including the Mini Compact and Mini Deluxe Compact have three
