EAR-Yoshino MC4 step up transformer

The ''Ideal Transformer'' must by definition 'transform one kind of energy to another without loss' no more or no less! EAR have achieved results for audio close to the ideal, for it will allow the very best of ''Moving Coil'' cartridges to extract the most possible information out of the groove. Most Active ''Head Amps'' have many flaws which inhibit the release of all the possible information out of the groove because the laws of economics and physics prohibits most designers from achieving the ideal, which is wide bandwidth minimal time distortion, minimum noise contribution, and maximum protection from external influences.

EAR explain: The Moving Coil cartridge is a much more efficient converter of energy than Moving Magnet but has the great disadvantage that its voltage ouput is not really practical for most amplifier technology to handle it. So if we take its product of voltage times current and transform it to a suitable form for most amplifiers to handle it we then find that we actually have gained an advance over the Moving Magnet in noise figures of at least 6dB. This means that we can achieve 90dB of dynamic range that the record potentially offers.


Hum Rejection - Greater than 60dB
Channel Separation - Greater than 70dB (20-20KHz)
Channel Balance - Less than 0.1dB
Rise Time - 2lsecs (any level)
Phase Linearity - Less than +,- 5 degrees (20-20KHz)
Frequency Response - 3Hz- 100KHz +0.2dB-1.0dB
Voltage Gain - X30, x24, x18, x10
Input Impedances (nominal) - 3 ohm, 6 ohm, 12 ohm, & 40 ohm,
Equivalent Noise Contribution - Less than 1dB
