Shpeaker Cablesh

[MarcAshken]

Ello folks, i've got alesis m1 mk2 active monitors and the hum i'm gettin could shake the house down. I reckon i've wired the cables up wrong, i aint sure how i've done it but its an XLR to jack connection. The cable only has two wires, hot and cold ( i'm guessin) Do i need an earth? On the xlr, what is hot and what is cold, likewise on the jack, is the ring or the tip hot? And should i wire hot to hot and cold to cold? Man i wish i'd listened in audio electronics now.
Thanx for any help u can give.

Whats up cuz! i have the same speakers but im not using the xlr's im just using the reg old 1/4 mono moster cable. i cant say why your getting a a hum but look at something like what i got.

for the 1/4" connector the tip is the hot (+) connection / the sleeve is the cold/ground (-) connection...for the xlr, pin 2 is the hot(+) connection / pin 3 is cold(-) / pin 1 is the ground...therefore you need to connect the tip(+) of the 1/4" to pin 2(+) of the xlr...connect the sleeve (-) to pin 3 (-) and pin 1(ground) of the xlr...you need to split the connection from the sleeve between pins 3 and 1 because this completes the ground path...subsequently whatever is picked up by the ground path is shared by the (-) side of the cable therefore introducing it into the signal...what would help the hum if it is in fact due to noise is using a TRS 1/4" connector and 2-conductor plus shield cable...these mate better with the xlr connectors which are intended for balanced use...hope this bit of info helps...also make sure that your solder is done judiciously and sufficiently...peace
