The MC1 is a fine example of a step-up transformer designed specifically for modern low output moving coil cartridges and optimised for use into moving magnet phonostage inputs. It features wide bandwidth, low distortion and carefully designed primary and secondary loading networks to optimise the performance and give beautifully reproduced transients, free from ringing. The step-up ratio and impedance make it compatible with a wide range of cartridges and effective screening against external magnetic fields minimises hum pickup from other equipment.
step-up transformers explained
Although the MC1 is compatible with most moving coil cartridges available today from makers such as Lyra, Koetsu, Ortofon, Audio Technica etc., anyone confused by the whole topic of impedances, transformer ratios and matching can read moving coil step-up transformers explained for detailed information on the subject, along with example calculations and a useful table of cartridge data for guidance in assessing compatibility.
