Okay so here is my dillema.
I have an Orion Concept 97.2 and it is capable of converting a non-balanced input into a balanced output. My Treo SSX 75.4 amp is capable of running in balanced mode also.

Now here is my problem, the EQ outputs the balanced signal via mini XLR connector and the amp can only recieve via RCA, whether the signal is balanced or unbalanced.

Now I have been doing research into this situation for almost a month in my spare time so I am fairley educated on the subject. I know I can build a cable that has the XLR on one end and standard RCA on the other. I also understand that when an RCA carries a balanced signal the center pin carries the normal phase, the outer collar carries the inverted phase of the signal while the chassis ground of the amp will serve as the ground referance. On the other hand the XLR outputs both phases of signal and the ground referance in one connector.

So if I were to build a cable that is XLR on one end and RCA on the other, what do I do with the ground referance signal from the EQ?? The EQ does not output a balanced signal via RCA only via XLR, so that is out of the question.
The other question I have is whther acheiving a balanced signal is really worth all of the hassel it will put me through??

I am willing to do it if it is worth it.

I have never heard the differance between the two so if you have experience with balanced signal please help me out.

Thanks,

Chris

balance eliminates all noises picked up by the cables by canceling them
the ground should be from one chassis ground to the other

How close is the 97.2 to the amp?

Will you be running balanced from the deck to the 97.2?

I dont get how a 'balanced amp' (Treo) can only have RCA inpputs (RCA's are unbalanced)... what am I missing [img]graemlins/dunno.gif[/img]

balanced can be used on rca's they just use say the centre as in phase and the sheild as out of phase
and then run a wire to chassis ground
some of the older kenwood ps series amps used balanced input as well

I havent heard of an RCA input (on an amp) that would except a balanced in. I'm using balanced in my car and the benifits are worth it.

The Audio Control uses RCA for balanced inputs..... and in alot of case you just float the shield gnd at one end where the rca is..... and connect to the XLR end.

I do agree the benefit of running balanced is worth it..... as my system is also balanced. [img]smile.gif[/img]

I tried both,

First, My Eclipse CD8053 via balanced RCA's at 16 volts to a Zapco C2K 2.0 amp via Symbilink.

And now, from the same deck via unbalanced at 8 volts to a JL Audio 300/2.

The result...Both signal are extremely quiet and clean. In all honesty, I was enable to hear ANY differences in term of signal quality from both amps.

i've never had a problem with decent rca cables and proper installation.
