Weston Precision Audio PAO Phase Animated Oscillator

PAO is a triangle core voltage controlled oscillator (VCO) with an additional triangle phase animator circuit which provides a copy of the 4 primary waveform outputs (triangle, saw, sine, and square) with adjustable phase lag from 0 to 180 degrees. Additionally the phase animator can be pushed past 0 and 180 to add additional harmonics. PAO provides through-zero linear phase modulation (P) and linear frequency modulation (FM), as well as exponential FM. A host of wave output shapes make for lots of flexibility, making PAO a great central VCO for any system. A precision encoder-driven 8-way octave selector adds to PAO's user friendly interface! PAO is ultra-stable under ambient temperature changes and holds great tuning over 8 octaves.
