Number DMX dimmers that can be controlled

Channels are merely handles to control a dimmer or a fixture. The Standard has 1 universe of Hardline DMX, the AV has 5. 2 hardline but all 5 universes it can operate can be controlled through sACN via network. if you need to have individual handles for each dimmer for live busking you would run out of handles pretty quickly. The intent of channels of control allows for easier manipulation of multi parameter fixtures. By selecting a channel, all associated parameters are accessible without having to do the math in your head to access any particular attribute like color mixing which can be quite a number of DMX addresses. if you have 80 fixtures in 5 different types of fixtures with multiple parametes of varying counts, its easier to grab a fixture then hit color or any other feature and access the feature the exact same way for all fixtures. 80 Source4 fixtures in direct+7 mode would be 1200 dmx addresses. 80 Revolutions with Shutters or similar count fixtures would be 2480. You might need to consider an Element 2 or other advanced console as the ColourSource might not be as advanced in capabilities as you might need. (edited for clarity and corrections.)
