Diamond II

From the Avolites HIstory website:

By watching how LDs used the Sapphire and inviting designers and operators to call into Avolites as and when the opportunity arose, we listened to the ideas and suggestions made and put these with our own, the pool of these ideas created a larger console, the Diamond II.

The Rolacue Sapphire had been designed to have 512 channels. This was to ensure the channel count was never a limiting factor of the console. In 1991 512 channels seemed a massive number compared to other consoles of 30, 90 or a huge 180! However it soon became clear that with moving lights consuming 20 channels each, more would be required. The Diamond II addressed this by increasing the channel count to 3,072 ~ 6 DMX lines. It's a rare event that requires more.
