Another commission from our friends at Coral Sound, this PCB is used in adding up to 8 additional inputs (per layer) to a vintage Neve 80xx series console. It accepts three kinds of input transformer which then feeds an external fader loop and returns to a BA440 (or BA640) buffer amplifier which can drive an external mute/solo/assign and then drop onto the mix buss. It is just the right shape to mount on the bulkheads or sit in the belly of a 8-channel bucket such as the righthand end of an 8058 frame.
In keeping with the application RC decoupling, coupling, and termination was done in Neve style, along with a serpentine ground. Metalwork in the example pictured by Coral Sound.
