This is a 60 W per channel direct coupling amplifier. It has a 4 line inputs and one phono input, separable preamplifier and power amplifier sections, posts for 2 pairs of speakers and a headphone socket tapping into speaker outputs. It lacks additional midrange potentiometer (present in many Marantz amplifiers from that period), but bass and treble controls are separate for each channel. The amp also has high, low and loudness filters, as well as the MUTING switch (-20 dB) and a complex mono switch that allows to listen to left channel only, right channel only, or both channels converted to mono. There are microphone inputs and special DUBBING input/output on the front panel (6.3 mm jacks), which doubles for the TAPE 2 IN/ OUT input/output on the rear panel. TAPE 1 and TAPE 2 loop sockets on the rear panel are additionally doubled – we have a choice of standard RCA jacks and DIN sockets. Interesting feature are the SCOPE sockets for connecting an oscilloscope, which could be found in top models of Marantz tuners and some receivers.
