Technical Specifications:
Output Impedance – 200 Ω
Recommended Minimum Output Load Resistance – 5 k
Frequency Response (50 kΩ Output Load) – 13 Hz (-3 dB) to 100 kHz (-0.3 dB)
RIAA Accuracy (50 kΩ Output Load) – Better than ±0.2 dB 100 Hz to 100 kHz
Power Requirements – 24 V AC at 150 mA maximum
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 Ω / 1 on = 100 Ω / 2 on = 150 Ω / 1 and 2 on = 70 Ω
– 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 Ω / Capacitance 1000 pF / Gain Setting High
