In the case of sending an unbalanced signal to a balanced input, for non-inverting operation; one may drop the inverting(-) input to ground with a 10k resistor and feed the unbalanced input to the non-inverting(+) pin. Ground remains equivalent.
Higher end equipment may use a proper balun to actually 'convert' the unbalanced signal to balanced, but this is normally unnecessary since the good effects of balanced operation are lost because of an unbalanced source in the first place.
I picked up a 1/4" balanced to rca converter cord at Sam Ash music center. But, now I have another problem. Samson rates it's RCA inputs on it's amps as -10dBV as compared to +4dBV for balanced.
WHat I think this means is that normal home audio rca outputs don't put out enough voltage todrive the amp to full output. In order to get nearly decent power out of the amp (for subwoofers), I have to crank the volume controls on it full throttle and adjust the output on my sub crossover.
Although, this does push the sub amp into clipping territory(clip lights flash) at fairly low output. This sucker is 275wpc channel and should push these 88-90db subwoofers with relative ease, but that's not true.
I suppose I could look into some type of voltage stepup transformer.
Does anyone know what the standard max voltage output from pro/live gear is comapred to 2V for home audio?
+4dB balanced is broadcast, -10dB unbalanced is consumer (although in reality it is often much higher). Meaning if you want to connect it to the output of a mixing desk or a broadcast cart player or the like, the +4 input is best, but the -10dB can be used by most consumer gear.
