Hi all,
with no peak reduction applied the LA-2A can serve as an amplifier with up to +45dB gain.
the amount of gain applied is determined by the input pot, which is a 100k log 'fader' type.
I am wondering if there is any sort of formula that allows me to convert input pot resistance to volume gain?
The idea behind this is to replace the input pot with a rotary switch and fashion a neve-1073-style gain control, with some line and some mic settings. I am thinking of having a fairly fine resolution in the line section (-5 to +10dB in 1dB steps) and then a coarser resolution for the higher gain settings (+15dB to +45dB in 5dB steps). But how do I calculate the required resistors?
or maybe Harpo has already done a spreadsheet for this sort of thing?![Big grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
