Step..... | Conditions | Result |
1.1 | Mix = 100% Ratio = 10 Attack = 0.1 Release =1.2 IN button pressed HF lift, 100Hz, 50Hz buttons released Negative meter probe on 0V |

1.2 | Step 1 conditions plus: Input signal = 0V Threshold on +15 Makeup on 0 | TP1, TP2, TP3, TP4, TP11, TP12 = 0VDC TP1: -0.000V <- meter indicated minus, but still all zeroes TP2: 0.000V TP3: 0.000V TP4: 0.000V TP11: 0.006V <- Small deviation from zero! TP12: -0.005V <- Small deviation from zero! |
1.3 | Step 1 conditions plus: Input signal = 0V Threshold on +15 Rotate Makeup from 0 to +20 | TP12 goes from 0 to -2.3VDC TP12 went from the aforementioned -0.005V to -2.347V DC |
1.4 | Input signal = 0V Makeup on 0 Rotate Threshold from -15 to +15 | TP13 goes from -1.8V to +2.8VDC TP13 went from -1.801V to +2.978V DC |
1.5 | Input signal = 3VAC (measured between output XLR pins 2&3 with compressor bypassed) Makeup on 0 Threshold goes from +15 to -15 |
3.019VAC was closest I could get on input TP4: 0.0528VAC (52.8mVAC) to 0.1902VAC (190.2mVAC) TP5: 0.348VDC to -1.203VDC TP11: 0.006VDC to -3.477DC TP12: -0x004VDC to +3.482VDC |
1.6 | input signal = 3VAC Threshold on +15 Makeup on 0 | Signal level (VAC) on
Same input voltage (3.019VAC) TP1: 1.513VAC TP2: 1.530VAC TP3: 1.516VAC TP4: 52.7mVAC <-- OFF by quite a bit! Looking at the schematic, I hope U9 and U10 are OK. U6 pin 1: -0.000VDC |
1.7 | input signal = 3VAC Threshold on -15 Makeup on +20 | Signal level (VAC) on
TP1: 1.512VAC TP2: 0.443VAC TP3: 1.516VAC TP4: 0.1902VAC (190.2mVAC) TP11: -3.477VDC TP12: 1.143VDC TP13: 1.697VDC |

On channel 2 board: V+: 16.26V V-: -16.42V On channel 1 board: +12V: 11.93V -12V: -12.24V |
2.2 | Step 1 conditions plus: Input signal = 0V Threshold on +15 Makeup on 0 | TP6, TP7, TP8, TP9 = 0VDC TP6: -0.000V TP7: 11.06V <-- Still problematic TP8: 0.000V TP9: 0.000V |
2.3 | input signal = 3VAC Threshold on +15 Makeup on 0 | Signal level (VAC) on
TP6: 1.514VAC TP7: 1.090VAC <-- Off here as well TP8: 1.518VAC TP9: 0.0525VAC (52.5mVAC) (seems to slowly move back and forth between 52.1mVAC and 52.5 to 52.7mVAC over the course of seconds) U16 pin 1: -0.001VDC |
2.4 | input signal = 3VAC Threshold on -15 Makeup on +20 | Signal level (VAC) on
TP6: 1.515VAC TP7: 0.1798VAC (179.8mVAC) <-- Off again TP8: 1.518VAC TP9: 0.1903VAC (190.3mVAC) U16 pin 1: 0.064VDC <-- Off as well |
