The PCB is all black and has gold plated contacts and vias. SSL has two versions of this interface: SSL 2 and SSL 2+. The "+" version has more outputs and offers MIDI connectivity. For this reason, many components are missing from the circuit board shown here. Obviously, SSL uses the same PCB for both versions of the product.

Although the input sockets are combined XLR/TRS, the signal paths are separate. Nice!

SSL uses high quality, mostly Japanese, components (Alps, NJM, AKM, Nichicon, Panasonic) throughout the product. The connectors are made by Neutrik. Nice!
