====== AOUT Module ======

=====Introduction=====

AOUT modules generate **Analog (Control) Voltages (and gate signals)** *. It provides **8 control voltage (CV) outputs with 12 bit resolution and 2 gate outputs**. It is used by various MIDIbox projects to control analog synthesizers and/or FX gear.
\\
\\
The **MAX525 DACs** feature better performance than the one used on the [[AOUT_NG]]. **So for perfectionists wanting to drive analog VCOs with maximum tuning precision, the AOUT is the right choice**. Bipolar operation is possible but needs some external parts. Althought, MAX525 is quite expensive and has limited availability.
