Preamp Output Level

Quick test of AO-28 output level.

From GeorgeBenton:

For a quick test I usually pull out the first four drawbars and press down key 25 (the C two octaves above the lowest C). I look for an AC rms voltage measured at the G-G terminals of around 2 volts, minimum --- higher levels, more like four volts RMS are more normal. (This test is presumably performed with the expression pedal "floored".)

SalAzz adds:

2 VAC RMS is low. ~4 to 6.5 volts P-P, or 3 to 5 volts RMS is more like it. The output of the consoles do vary considerably.
