MIT’s Phono Interconnects
are specifically designed for the unique problems that cartridges and phono preamps present. Cartridges generate extremely low output levels, with "high” output cartridges putting 1/1000th the signal level of a typical CD player or other line level source. Noise picked up by the cable can easily distort that signal. Additionally, the terminating impedances of most phono preamps are very different from typical line level inputs. This will alter the articulation of the cable if not designed with that in mind.
To solve both problems, MIT uses a unique doubled-shielded design for noise-free playback, and unique networks with selectable impedance settings (100 Ohm, 1 KOhms and 47 KOhms) in order to get the most from your records.
