2023年1月10日 · 2) The "best" way to connect a RCA based pre-amp to XLR power amp is using a XLR cable terminated with a RCA connector. If the cables are not long (whatever that is) a RCA (female) to XLR (male) may work very well. And no, no damage to the speakers or the amplifiers in the speakers - if the contacts are correctly connected.

2020年8月5日 · Just to clarify (which I already corrected) I messed up with saying XLR -> RCA. I need the reverse of RCA -> XLR, which I corrected the title and post #1 to say. My AVR has rca outs and my desktop dsp only has RCA outs. Everything I currently have only has RCA outs. So I need to make RCA to XLR cables as all my external amps have XLR inputs.

2020年7月16日 · Virtually any amp with XLR connectors will work with an RCA -> XLR cable, but many amps are optimized to be drive by differential input which one cannot get from a single-ended input with only an RCA->XLR cable. They will usually operate but at -6dB output level; in effect only 1/2 of the amp is amplifying an active signal.

2022年6月14日 · Being a low source impedance, both RCA based and XLR based cables can be long or short. Where XLR shines is its balanced nature. This makes pickup of hum and EMI much less of an issue since these are cancelled by the common mode rejection of the receiving component. It is much more common to use XLR for long cable runs because of this.

2020年4月29日 · Back to XLR to RCA adapters: There are three and a half types of balanced output stages: 1] transformer 2] impedance / passive 3a] active / powered / grounding tolerant 3b] active / powered / grounding intolerant no single XLR to RCA adapter will work in all cases.

2024年3月12日 · Genelec recommends an XLR-RCA cable with XLR pin 2 -> RCA tip; XLR pin 3 -> RCA sleeve; XLR pin 1 (shield) -> RCA sleeve. Thus, the XLR’s pins 3 and 1 are tied at the RCA. All the other stuff you mentioned is of little or no concern. Just connect your gear and enjoy it.

2024年1月2日 · Lets say you used the amp without converting the XLR input, as in you went XLR -> XLR and the pre-out voltage was 2V (+1 - (-1)). With an input gain of 28db, that would be 50V amp output. Now lets say you used an RCA to XLR cable. As in, going from RCA at the preout to XLR on the amp side. The RCA preout voltage is also 2V (+2 - 0).

2019年6月6日 · if you DIY, pin 2-> RCA "hot"(center of the rca), pin 3 &1 -> RCA"cold"(exterior of the RCA). I use this kind of DIY cable between amp and DAC with neutrik NC3MXX connector and copper silver plated/ptfe wire for years, no troubles at all . In my case, without any shielding (2 braided independant wires) I just connect the pin 3 to the 1 with an ...

2018年5月20日 · It is possible that the XLR > RCA cable used is shorting half of the output stage to ground, upsetting it - check cable pinout. Generally adapting this way round only makes sense if it is the only way to connect two devices at all, as reaping the benefits of a balanced connection hinges on the balanced input stage.

2023年1月10日 · You can find active RCA to XLR converter boxes that use amplifiers to generate a true differential output. The converter would have a short RCA cable to the DAC and long XLR cables to the speakers. And the old-school unbalanced to balanced transformers are still available, which require no power but may not have a flat frquency response.
