HITACHI CP-90/900 (1983)
This Hitachi Super Mini Component System was introduced in 1983. It was a modular concept that consisted of the CP-90S or CP-900S amplifier and the clip-on CP-90REX docking station for 4 removable components and the matching speakers. There were available two systems: the CP-90 and CP-900. The CP-90 had only 3 components in the docking station: tuner, cassette recorder and EQ with the empty space covered with a decorative element. The CP-900 had 4 components installed: cassette player, cassette recorder, tuner and EQ with the amplifier having different input configuration. The docking components are interchangeble which means one could have a system with 3 cassette players installed or change the position of the tuner and cassette player in the docking station. The detachable tuner/cassette components can be used as portable units with a headphone. The Dolby noise reduction system is housed inside the 5-band graphic equalizer unit. The amplifier section has a power rating of 12W/ch (THD 10%) delivered to a pair of easily detachable loudspeakers, each with a 9cm woofer and 2cm ceramic tweeter.
