(an AD558). The micro-controller sequentially applies the levels for each output to the

Digital to Analog chip (abbreviated D/A) while switching the output of the D/A to the 24

output buffers. The switching circuit (three 4051 chips) allow one D/A to service all

outputs with less than 1/250 second delay between the time a DMX level changes and

the analog output is updated. Capacitors hold the 0 - 10 volt level while the other

outputs are being updated.

Diodes on the output allow multiple consoles to control the same dimmers by what is

commonly known as Pile-On of the signal.
