(16) AUDIO AMPLIFIER

- audio amplifier

	SIGNAL LEVEL Use this knob to raise the volume of the input signal to the level you need. Since this module employs an "auto-pat" system, it can handle any input from line level to mic level; adjustment is always smooth and precise. Adjust input level so that the peak level indicator (above this knob) turns on when the input signal level is at peak amplitude.
	AUTO SIGNAL INPUT For input signal from electric guitar, drums, vocal, tape deck, or any other audio signal source.
	AMPLIFIED OUTPUT Provides the amplified output signal. If you have adjusted signal level so that the peak level indicator turns on when the input signal is loudest, you can use this output signal as an audio signal source (instead of the VCO, for example), and connect it directly to the MS-50's VCF, VCA, or other modules.
	TRIGGER OUTPUT This provides a trigger signal produced from the audio input; you can use this to trigger operation of the EG.
	ENVELOPE FOLLOWER OUTPUT This provides an envelope signal that is proportional to the instantaneous changes in volume of the audio input signal. In other words, this output voltage corresponds to the input signal amplitude.

With this audio amplifier, you can go beyond the usual sound synthesis capabilities of most synthesizers and use external audio signals as a sound source and control signal source. After passing through the A Amp module, the amplified audio signal and its corresponding trigger output and envelope follower output signals can be patched to other MS-50 modules to "resynthesize" timbre and other aspects of the sound. This means that you can easily set up a drum synthesizer, vocal synthesizer, and so on.
