Volume/attenuator control board kits  


Click to see more pictures

  These boards are combined front panels and CPU boards. They can be used to control one volume control/attenuator board.

The controls consist of a rotary encoder to set the volume level, and an IR sensor for remote control operation. The VolControl1 board does not include a display, so there is no indication of the volume level. The VolControl2 board includes a 2-digit LED display, and the VolControl3 board can control an LCD display. Otherwise the boards are identical.

The board needs a regulated 5V supply (a 7805 regulator for instance). The sizes are 70*27mm (VolControl1), 99*33mm (VolControl2) and 67*35mm (VolControl3).

For displays suitable for the VolControl3 board see the "Accessories" section.
