Slim type component of a Marantz Stereo control amplifier of component stereo 50 series.
An operation of a picture recording etc. is possible to Tape1 in an FM broadcast, carrying the Rec out selector and carrying out a record play.
A phone amplifier part selects carefully and uses especially elements, such as a transistor, and is attaining high-quality sound-ization while it performs a Low-TIM design.
Moreover, it corresponds to MC cartridge by carrying MC position, and also various cartridges are supported by carrying 3 position cartridge selector in Phono1.
In addition to the OUT position removed from a circuitry, the tone switchpoint which can bypass the tone amplifier itself also carries only the tone element in the tone control.
A loudness circuitry, a subsonic-speed circuitry, etc. of two positions are carried.
