Thank you Alain davehouck Moderator Username: davehouck Post Number: 7854 Registered: 5-2002 Posted on Wednesday, April 08, 2009 - 8:57 pm:    I can't tell, and the manual doesn't say anything about it. jimmyj Junior Username: jimmyj Post Number: 48 Registered: 8-2008 Posted on Wednesday, April 08, 2009 - 11:19 pm:    It is obviously capable of operating on any of those three marked input voltages but there is no indication whether it is "self sensing" or you need to move some internal switch or jumpers. Research it before you try! pacificshine Junior Username: pacificshine Post Number: 26 Registered: 7-2008 Posted on Thursday, April 09, 2009 - 9:50 am:    All Aguilar power amps require an internal (I saw it done once and it was simple) wiring modification when switching AC power input. They will not sense the voltage change and there is no external (back panel) switch for that. That includes the new DB-751 model.
