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.

2022年9月4日 · As someone who installs pro amps with xlr inputs to consumer gear with rca cables for a living there are a couple of things being overlooked. Xlr will reject noise much better than r a cables. RCA output run at -10db, xlr pro gear at +4db. This makes to the noise vs music separation, ie noise floor. It can also make pro amps sound weak.

2023年6月17日 · This is a review and detailed measurements of the Neutrik NA2F-D0B-TX XLR to RCA (and vice versa) adapter. It is on kind loan from a member and costs US $35. View attachment 292813 The device feels very solid and oozes quality when you look at the RCA connector: View attachment 292814

2023年12月17日 · For testing I focused on RCA to XLR since many want to hook up amplifiers with unbalanced out to an amplifier with only balanced input. EDIT: added the reverse conversion measurements as well. The Matchbox HD Performance Measurement I hooked up RCA out at 0.83 volts to get nominal 4 volts out of XLR connection:

2023年9月22日 · The difference between XLR and RCA is not a sound quality difference. The XLR cable is "balanced". The RCA cable has signal + ground. The XLR cable has signal + , signal - , and ground. The signal - is exactly reverse polarity with signal +. On the XLR balanced cable, the signal + and signal - are summed together to noise cancel each other.

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).

2024年12月30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.

2021年10月4日 · Unlike with RCA, in an XLR interconnect the ground/shield conductor that equalises the ground potential between the two devices, and therefore carries a current, is not used to carry the signal. That which can be asserted …

2023年1月1日 · Differential ("balanced") XLR components ideally have higher SNR (less noise for the same signal level) and lower lower distortion compared to single-ended RCA components. In practice, for audio, the difference is usually negligible and the difference between them is related to other things like the design implementation.

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.
