#1 balanced connection to a 4 channel amp...will this work
Posted: Fri Sep 21, 2012 12:35 am
Hi everyone, looking for someone with more experience than me as to an idea I have with some recently acquired HiFi.
I have an M-DAC which has the option of balanced output via XLR. I have just bought a beast of a SS amp off ebay - it is a DBX DX3 4 channel power amp.
It has 2x stereo phono inputs, with 3 modes, 4 way, 3 way and bridged 2 way. Someone suggested I could make up special XLR to 2 phono cables. Hot to one phono cold to the other, both sharing the earth. These 2 cables could then be used as the input with the amp in 4 way mode. connecting the speakers to only the red terminals.
I have never used balanced connections and this is pushing my knowledge to the limit. But as i understand this arrangement, the speaker would see the differential between the +ve and -ve polarity on the two speaker posts and this would cancel out any common noise. Have I got this right and does this sound like a sensible plan?
The alternative is to switch the amp into bridge mode and connect up using a single set of unbalanced phono cables.
thanks for any help here...
