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 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
