In Reply to: M60 II input sensitivity. posted by Grigoris on June 7, 2004 at 17:55:47:
The M-60 Mk. II does not invert polarity, and XLR pin 2 is positive. The amplifier is unconditionally stable for any load condition. Input impedance was 98kW at the unbalanced input, and 199k at the balanced input. Input sensitivity for 2.83 V RMS into 8W was 0.181V RMS, or 23.9dB. With a 4W load, input sensitivity was 0.284V RMS, or 20 dB. The gain was identical for both the balanced and unbalanced input; however, any preamp used with the amp will need more gain than usual to get maximum power into 4W speakers.
