Audio Database MARK LEVINSON ML-1L 630,000yen(1977 release) 720,000yen(around the 1979 time) Description 　 Control amplifier which the enhancement was performed in spring of 1977 based on JC-2, and was born. The complimentary push-pull circuit of a whole page pure class A operation is adopted. The LEMO connector is used for an input/output terminal. The phone amplifier gain and the input impedance had the optimal System A4E for System D5 and System D6 in which MC cartridge hardwired connection is possible in addition to standard System A3, an EMT cartridge, etc. The power-source part has adopted another case. Rating of a mode Form Preamplifier Stream composition * The stream composition by five modules One active filter for power sources An audio amplification part is a two-step amplifier stream composition of two 2ch each.
