Hi,

I have a Kelso console and the jig I made to test the 3126 modules as follows:

    1 - IP Hi
    2 - IP Lo
    3 - Chassis
    4 - 0V
    5 - -14db prefader/post eq out
    6 - fader top
    7 - wiper
    8 - fader bottom
    9 - gain boost
    10 - 0V for above
    11 - 0V for below
    12 - Unbal out
    13 - Unbal out
    14 - 0V for above
    15 - B+
    16 - 0V
    17 - Chassis

Thanks!!!

B+ is 24V, right?

Do you know where I can find schematics for the 3126 or 3116?

[John Klett]

yes

it is a single 24 volt supply - figure 100mA per module

B+ is +24 volts DC
B- is   0 volts



Some same information plus some more information
