MCX Moving Coil Step-Up TransformerType
Free US shipping on all phono stages!
This step-up transformer uses the same high quality cores as used in the MCL, again supplied by Lundahl of Sweden, but features a lower turns ratio than the MCL to accommodate cartridges with higher outputs. The turns ratio of the MCX is 1:10, making it compatible with cartridges with outputs of up to 0.9mV, which includes models from Benz Micro, Clearaudio, Koetsu, Lyra and Van den Hul.
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 of1:10 makes the MCX is compatible with a large selection of moving coil cartridges available today from makers such as Benz Micro, Clearaudio, Lyra, Koetsu, Ortofon, Audio Technica etc., but is particularly suited to cartridges with higher than average outputs, those in the range 0.6mV to 0.9mV.
