Frequency response with a cartridge DC resistance of 5 ohms
Due to the lossless core of the transformer the input impedance is high and constant.
This results in the flat frequency response of 20 Hz – 75 kHz (-1/-3 dB) even with a car-
tridge resistance up to 5 ohms.
Note
Based on its design, the transformer tends towards a drop in gain at low
frequencies. If the pickup cartridge/arm resonance is under 8 Hz, this al-
lows for device operation with the subsonic filter switched off.
