![]() ![]() The volume control will be an plugable module too - since currently there is a hot debate if LDR/chips or stepped attenuators are the way to go. This module will be plugable in some way so that you can choose the technolgy you like (opamps, discrete or whatever). To convert between single ended and balanced there will be an an single ended to balanced converter. ![]() The output can be balanced or single ended – according to your needs. For each input it is configurable if it is balanced or single ended. The basic input selection can switch between a number of balanced or single ended inputs. ![]() There is plenty of help out there to programm it to the specific needs. The decision to base it on Arduino is to make programming as easy as possible. It will have plenty of outputs for LEDs and plenty of inputs for buttons, rotary encoders or even analog potentiometers. ![]() To give you an image of the whole system I have drawn an image:Īn Arduino compatible CPU is driving the whole system. Stay tuned! PCBs will come in the near future (I really need it). Originating form the simple question (see below) of how to have a silent, high quality volume control & input selection I have decided to build an passive ♜ontroller based, arduino compatible preamp input selection & volume control. ![]()
