INSTALLATION
●T43 is a 4hp Eurorack precision CV adder and transposer
●The modules consumes 20mA from the +12V and 10mA from the -12V supply,
it does not use the +5V rail.
●Carefully check the orientation of the 10-pin power connector, the red stripe
(-12V) should be at the bottom of the module, see the labeling on the PCB.

BASIC OPERATION
●Inputs:
○A: CV/audio input A which gets added to the SUM output
○B: CV/audio input B which gets added to the SUM output
○C: CV/audio input C which can be added or subtracted from the SUM
●Controls:
○2 oct: add or subtract 2 octaves (2.000V) to or from the SUM output
○1 oct: add or subtract 1 octave (1.000V) to or from the SUM output
○4: add or subtract 4 semitones (0.333V) to or from the SUM output
○2: add or subtract 2 semitones (0.167V) to or from the SUM output
○1: add or subtract 1 semitone (0.083V) to or from the SUM output
○C: add or subtract the C input voltage to or from the SUM output
○in the switches’ middle position, nothing is added or subtracted.
○any number of steps between -43 semitones and +43 semitones can be
added / subtracted with the right combination of switches. e.g. to add 7
semitones, set +4, +2 and +1. To add e.g. 11 semitones, set +1 oct and
-1 semitone.
●Outputs:
○SUM sum of A + B +/- C and the transposition switches
Calibration
The module comes already calibrated, so there is no need to do this for normal
operation. In case the calibration has been modified and needs to be redone follow
these steps:
●power up the module and let it warm up for at least 10 minutes
●disconnect all input signals and set all switches to the middle position
●set the +2 oct switch and measure the SUM output signal with a high precision
voltage meter (a meter that can measure down to 0.1mV is recommended)
●adjust the multi-turn trim potentiometer on the back of the module until the
SUM output signal reads 2.000V (the exact voltage should be between 1.9995V
and 2.0005V)
