Hello

Two questions, please, about my beomaster 5000 amp: i have had it for some time but after a house move I am trying to re-set it up and i was clearly not clever enough to make note of things in tearing it down and am at a loss now...

FIRST question: the speaker cables... they have bare wires at one end for the speakers and, at the amp end there is a flat bit and a pin bit - i assume these are 2 pin DIN: the question is, which, flat or pointy, please, is +ve and which is -ve (which i assume is necessary so that phasing is correct)

(EDIT: found the first answer, cheers: blade is -ve, pin is +ve!!) 

SECOND question which is where i am at a total loss: i had only the speakers and a CD/DVD player connected to the amp - and my DVD/CD player has only phono connectors for audio output.

I am also certain that i am correct in recalling that it was hooked up to the AUX because i am sure it was always AUX/CD I pressed on the MCP to turn it on - - but I have no cables with 7pin connectors on one end and can't for the life of me see how the CD/DVD player was possibly connected to the AUX/CD without 7pin connectors such since the phono plug connections seem, according to the manual and the 5000, to be for phone, tape2, line and pre-amp: the AUX seems to be only 7pin and without 7pin connectors i see no way to connect to it - - and the only cables i can find have phono plugs on both ends or phono plugs one end and bare wires the other ( i have waaay too many cables and made the stupid mistake of putting the existing set up cables in a box with many others!) but i have none with the 7pin connector...
 
failing that second question making any sense at all, i can also simply ask: what is the best way to connect my CD/DVD to the beomaster 5000 amp for playback, given that I have cables with phono plugs on both ends, on one end with bare wire on the other?

apologies if i my questions are posed poorly but i hope the points are clear - and thanks for any help!
