The Control Board is the long one shown; front and back. The short board is the audio board in the previous post.We refer to the Control Board as the Control Matrix because it is actually 3 modules -- Volume, Selector, Logic/PSU -- which can be snapped off and positioned to suit any size faceplate (the Volume and Selector modules communicate with the Logic Module through ribbon connectors). Or it can be mounted as one unit to a suitably sized faceplate. The 240mm Projekt chassis happens to be one that is.
The center module contains the Logic and the PSU. Note: no extra transformer is needed; as you can see, it is in place on the module and ready to be connected to either 115 or 230v mains. Signal stays on the Audio Board; the Control Matrix is programmed to do all the switching and housekeeping and via ribbon cable tells the Audio Board what to do with the signal.
The selector and attenuator switches have a shaft which allows a knob and manual control from the front panel -- or remote control using standard RC5 encoding.
The blue LED are meant to be visible through the faceplate and a drilling template is provided. The selector module has 5 LED installed -- one for each input. The Volume Control Module has 12 LED installed BUT there are actually 127 steps! We didn't think you would want to drill 127 holes for 127 LED.
Native attenuation is -52db to 0db from a reference 3.5V rms. But you horn guys are going to love this: Shunt mode allows -66db to -15db!
