Dimensia MTR120 Audio Cassette Recorder

Notes:

• In 1985, RCA introduced the Digital Command Component series. The fundamental component of this "RCA Audio System" is the MSR140 Stereo Receiver, which provides system control functionality for audio components only, with no need to purchase a Dimensia television. This Digital Command Component series includes the MTR115 as well as the MTR118 Audio Cassette Deck, which is identical to the MTR120 except for the styling of the unit.
• In 1987 the MTR225 Dual Cassette Deck replaced the single cassette MTR120 in the Dimensia line.
