Problem – The SSL 4000 G+ at Zac has a plethora of niggling issues with various channels. Many of the switches that pass actual audio (sometimes referred to as ‘analog switches’ to distinguish them from switches controlling relays or JFET ‘relays’) are dirty and failing.

Solution – replacement of the ‘in,’ float, split, phase, and pan switches. Our three-man switch-replacing and diagnostic team included Grammy-nominated (and Zac Recording head) engineer Tony Terrebonne and Suspect Device occasional staffer Tommy Terrebonne who was visiting his twin brother while soldering. After all switches were replaced a few channels were still ill-behaved. Edge connector issues were corrected by cleaning and logic problems by replacing an open small fuse on the power rail coming in to one channel.
