AJH Precision Voltages black

Sometimes real precision is required with pitch control voltages - this module features a super accurate "Cal" output, which is accurate to <1mV over 20V, translates to one cent over 20 octaves! It is ideal for calibrating the scaling of VCO's.

As well as being a precision voltage source it is also a very accurate voltage adder, it has two channels (A & B) and both full volts (octaves) or 1/12th volt increments (notes) can be either added to or subtracted from the incoming signal. Perfect for adding a voltage offset to the output of a sequencer or it can be used to add switchable octaves to a VCO which only has coarse and fine tunes controls.

It also has a "mix" output, which allows either A channel on its own, or with the three way toggle switch channel B can either be added to, or subtracted from channel B, and this is in addition to the addition and subtraction per channel mentioned earlier.
