The Moonriver 505 phono stage is the result of over two years of research and development. It is equipped with four cartridge inputs, which means it can support up to four turntables, or up to four tonearms on one turntable. The phono stage allows you to adjust the input parameters using knobs on the front panel to perfectly match the characteristics of MC or MM cartridges, as well as the equalizer curve for records with a speed of 78 rpm. Settings for each input are saved in the device memory.
