The machines have already been delivered and are currently being used on the Australian Open tennis.
The investment comprises six high definition servers and four standard definition ones.
Gearhouse Broadcast managing director Eamonn Dowdall said: “The new HD XT EVS's transform the possibilities of all our productions.
“With native Codecs of all the mainstream editing systems and two completely independent network protocols this increased flexibility leaves you hard pushed to stretch it's bandwidth even in HD and of course the powerful and consistently reliable replay functionality which made the EVS famous remains.”
The new servers will also be used on coverage of the BBC's Rugby Union Six Nations Championship and Champions League football for ITV Sport.
