LF-AMP introduction

Well, that's refreshing.

"A tongue in cheek introduction to what's otherwise a rather boring module."

"The LF-AMP module combines two modules in one chassis:

First, on the left, is a precision triangle wave LFO, featuring:

Two pairs of outputs, each with its own amplitude control ('amount' as most would call it);
Direct and Inverted outputs in each pair;
A precision BIAS control for each output which determines the center of the voltage swing;
HI/LO range for rate, for a total range of about 20Hz down to about 1 cycle every minute.
Easy to see rate indicator LEDs showing the positive or negative swing of the output.

Second, on the right, is a high gain utility amplifier for headphones or line level sources, featuring:
Stereo inputs and outputs, with Normalled output for two individual outputs, or signals combined into one stereo jack ('2/MIX')

A bit more about the rationale...this module was designed for use with our Stereo Ensemble instruments. We needed a specialized LFO for our phaser modules, and an amp for final output, so they were combined into single unit. It's the peanut butter and anchovies of the modular world! The LFO output can be reduced down to a very tiny voltage swing, and then precisely located to work with devices needing those conditions...but it can also be used to give an exact range to a VCO, or an exact amount of depth to a VCA, etc. And since there's an inverted version of each output, two of something can work inthe exact opposite direction if desired. There isn't much to say about the amp; it's just a high quality amp for headphones which works to drive line level sources as well, using the LM4580 amplifier chip."
