Rega Fono MC Mk4 Phono Preamplifier

The Fono MC MK4 has been designed to be effective, easy to use, and above all, to reproduce music.
The Fono MC MK4 uses the Linear Systems low noise LSK389 FET in an all discrete input stage where low noise and linearity are vitally important to get the best from an MC cartridge. Because of the high input impedance of FET, the loading effects of the amplifier circuit are minuscule and do not affect the performance of the cartridge.

Technical Specifications:

Output Impedance: 200 O
Recommended Minimum Output Load Resistance: 5 k
Frequency Response (50 kO Output Load): 13 Hz (-3 dB) to 100 kHz (-0.3 dB)
RIAA Accuracy (50 kO Output Load): Better than ±0.2 dB 100 Hz to 100 kHz
Power Requirements: 24 V AC at 150 mA maximum

Load settings for adjustable MC stages:

Input Sensitivity (for 200 mV Output): 4 off = 133 uV / 4 on = 67 uV
Input Loading Resistance: 1 and 2 off = 400 O / 1 on = 100 O / 2 on = 150 O / 1 and 2 on = 70 O
Input Loading Capacitance: 3 off = 1000 pF / 3 on = 4300 pF / Gain (at 1 kHz) / 4 off = 63.5 dB / 4 on = 69.5 dB
Maximum Input Level (at 1 kHz): 4 off = 6.7 mV / 4 on = 3.4 mV
Factory settings for all Rega MC cartridges: Impedance 100 O / Capacitance 1000 pF / Gain Setting High
