Old HMI head with new ballast

[Eimulis]

Hi, is it possible to use old Sirio 4k HMI head and new arri or similar ballast

Will it be enough just to make an adapter cable?

The head appears to have an older LTM connector, which is rather strange since the 575's and 1200's came with VEAM connectors like you need for this. If you have the tools and knowledge, you could likely swap out the connector for less than the cost of an adapter, but either way you would need to make that conversion. Once that's (correctly) done there's no reason it shouldn't work.
