Glide On Fade Awesome Switch Wiring

If you are installing the Awesome Switch into an existing 1272 module, its fairly straight forward and can be done in about 45 minutes or less if you have some experience soldering. If you are good at following instructions, you can install the switch and do the conversion with little incident.

Step 1: Remove top and bottom panels from the 1272 module. It should look similar to this.

Step 2: I recommend replacing the power filtering capacitors, one should be mounted to the front panel, the other to the rear connector. For my taste I have settled on a 4700uf/25v cap up front and a 680uf/25v cap on the rear connector. These values are much larger than the values neve originally specified but caps were physically much larger 30 years ago when these were manufactured and the value of those caps could have been chosen based more upon what would fit in the package vs. what sounded best. Do some experimenting and see what you like, or install my reccomendation or install the original stock neve values, 1000uf/25v in the front position and 470uf/25v on the rear connector. Once you've completed this step you'll probably be good for the next decade with your power filtering.

Step 3: Remove sub front panel containing the fader. Install Awesome Switch directly on the front panel. The fader pot can either be relocated to the bottom of the unit and you can drill the front panel or if you are racking the module, you can mount the fader externally, choice is yours.

Step 4: Remove wire from Pin 7 on the input transformer. It is the small square green transformer labeled "10468" mounted on the middle divider panel inside the module. Connect a new wire from Awesome Switch terminal labeled "10468 pin 7 mic TX" to pin 7 on the input transformer. There should be a resistor and capacitor located on the transformer. Remove and discard the resistor and either leave the cap on the transformer or mount it on the switch PCB. 10468's should have a 180pF cap which can be mounted in position C1 on the board. 31267's will have a 2200pF and that can be mounted in position C6 on the switch board.

Step 5: Solder an 18K 1/4 watt resistor to pin S on the middle connector which the 283AV amplifier circuit board is plugged into.

Step 6: Connect a wire from Awesome Switch terminal labeled "Output U" and dress it to pin U on the 283AV connector.

Step 7: Solder the other end of the 18K resistor from pin S that you just hooked up along with the new wire you just ran from the Awesome Switch "output U" to pin U on the 283 AV connector.

Step 8: Connect a wire from Awesome Switch terminal labeled "Gain Boost T" and solder to pin T on the 283 AV connector.

Step 9: Connect a wire from Awesome Switch terminal labeled "Signal GND V" and solder to pin V on the 283 AV connector.

Step 10: Solder a 1.5K 1/4 watt resistor to pin K on the 283AV connector.

Step 11: Solder the negative leg of a 100uf/25v capacitor to pin J on the 283 AV connector.

Step 12: Connect the positive leg of the 100uf/25v capacitor to the other end of the resistor soldered pin K on the 283 AV connector.

Step 13: Have a righteous rock and roll party, your 1272 is now a mic pre built exactly how Neve designed this amplifer to be used. Your properly wired module should now look similar to this:
