Threecircles Recording Studio - Hairball 1176

Hairball Audio 1176 Compressor Build Stage 3

Okay so the next stage is to get the switch units connected up. The Hairball audio compressor kit comes with 2 switch units, one for the meter switches and one for the ratios. The pack also comes with 2 mini PCBs for the switch assembly. Solder on the required resistors and then solder in the switches themselves as per the photos below:

The next stage that I do as this point os to wire in the XLR input and output and also hook up the input transformer and hook that up ready for the main PCB:

Next we can solder the main input section of the PCB and also hook up the power transformer and test that it’s working before populating the rest of the PCB…….
