The MCL uses transformers supplied by Lundahl of Sweden and is a superb step-up transformer designed specifically for modern low output moving coil cartridges and optimised for use into moving magnet phonostage inputs. It features very 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 core materials and winding techniques employed in the manufacture are unsurpassed and feature multiple primary and secondary windings configured to cancel hum pickup from external sources as well as minimise inter-winding capacitance and maximise bandwidth. The step-up ratio makes it compatible with a wide range of cartridges and our proprietary loading networks maintain a 100 ohm input impedance, also compatible with a wide range of cartridges.
step-up transformers explained
Although the MCL 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.
