Hi everyone, I contacted control4 and they confirmed via the serial numbers the amp and audio matrix were first sold to a dealer in 2013! 8 years old!
He claims he didnt know it was old products! (hes not a C4 expert)
I have spoken to the company who installed it and they are due back today to install a new triad amp, audio matrix and controller.
I am very luckily the amp didnt work otherwise I may not have worked out this was very old stock.
I have learnt a valuable lesson, only use authorised dealers!
