input sensitivity..which is better??

Just have a question regarding the input sensitivity ratings of RCA line inputs on AVRs. Example, input sensitivity=500 mV. Another example, input sensitivity=1V. Which of these would be considered better?? I don't have much knowledge on this so any input would help. Thanks!!

Both are a bit low, 2V is the usual.Political Correctness'.........defined

Really?? I've never seen an AVR that has their RCA line level inputs at 2V...I've seen that in car audio head units..but I'm referring to home audio lol.My Setup: Denon AVR X3600h, Polk Signature S50 Fronts w/ S30 Center and S15 Rears, LG UBK90 4K Player, TCL 6-Series 65”4k TV -
You're right, don't know what I was thinking about. It would be in mV. My AVR is 400mV, some other gear I have are 330mV and 200mV.Political Correctness'.........defined

I believe input sensitivity is the amount of power needed from the source in order for the preamp to produce max output. But I do believe most sources output at >1.5v, therefore either spec would be met. Similiar the input sensitivity on my power amp is 1.3v, it would at least that from the pre-outs to reach its max gain of of 28db.Oh, Listen here mister. We got no way of understandin' this world. But we got as much sense of this bird flyin in the sky. Now there is a lot that bird don't know, but it don't change the fact that the world is happening to him all the same.

If I understand this correctly, the 500 mV input sensitivity will play louder/better than the 1V input sensitivity??...as far as home audio is concerned??My Setup: Denon AVR X3600h, Polk Signature S50 Fronts w/ S30 Center and S15 Rears, LG UBK90 4K Player, TCL 6-Series 65”4k TV -
It would be saying that it reaches full output with less signal in when you have the lower number. But I don't know that I would consider that better in any way at all. Actually, it could be the opposite.
Many preamps have too much gain. You can't use much of the pot travel...forcing you to use the first little bit all the time.
Possibly related could also be that it'd be easy to overload the inputs with too much level. Some CD players in particular are known for voltage out way above the -10 "normal", which is .775 volts.

PS...overall system gain is something you just don't see talked about much considering how much it plays into ease of use and even fidelity. In an integrated, it should be taken into account but a real low sensativity doesn't seem to be an advantage I can think of once it's too low.A so called science type proudly says... "I do realize that I would fool myself all the time, about listening conclusions and many other observations, if I did listen before buying. That’s why I don’t, I bought all of my current gear based on technical parameters alone, such as specs and measurements."

Yup. Your 2V number is the standard output of most modern sources; CD player, DAC, etc and preamps can be much higher.
The input sensitivity is the voltage required to drive the amplifier section to full rated output, or average rated output depending on how the manufacturer lists it. One of the issues that receivers and integrated can have if not well designed is clipping the pre section, while not fulling driving the amp section. -
That would be it Jake, thanks.Political Correctness'.........defined

Always happy to put in my .02. :redface:That would be it Jake, thanks.Just have a question regarding the input sensitivity ratings of RCA line inputs on AVRs. Example, input sensitivity=500 mV.

Neither is better. If you are using a standard source with a fixed output of 2V, either receiver will be fully driven; stand-alone phono preamps and tuners can be different. Input sensitivity really only matters these days with matching preamps and amps. -
^^I agree, with the exception of using the analog out of an mp3 player as a source. The output is well under 2v requiring a low input sensitivity for max output. I wouldn't suggest this method for any decent sq, however.Oh, Listen here mister. We got no way of understandin' this world. But we got as much sense of this bird flyin in the sky.

What about the analog audio out on a Bluetooth reciever??My Setup: Denon AVR X3600h, Polk Signature S50 Fronts w/ S30 Center and S15 Rears, LG UBK90 4K Player, TCL 6-Series 65”4k TV

I wouldn't use it if I didn't have too, the built in dac wouldn't be as good as the one the receiver. If it has a digital out use that instead.Oh, Listen here mister.

I kinda have to...but the Bluetooth receiver has aptX decoding which is nice:-)My Setup: Denon AVR X3600h, Polk Signature S50 Fronts w/ S30 Center and S15 Rears, LG UBK90 4K Player, TCL 6-Series 65”4k TV -
Bluetooth is never a preferred format if you are going for sound quality. What is your digital source; your phone, iPod?

Are you are referring to the Bluetooth receiver in your sig? I thought the Rocketfish receivers had a digital out. The Bluetooth adapter from my Onkyo the UBT-1 maintains the digital signal throughout, no analog conversion, therefore the sound quality isn't compromised any more than the original aptx file compression. I agree with you Jake, if going for sound quality then certainly do not use bluetooth, however, with AptX and the avr's dac, it is very acceptable.Oh, Listen here mister.

You're correct the Rocketfish receivers do have a digital out, but I cannot use it b/c the Sony AVR had its last run :-(. As of right now, I'm using a basic stereo receiver with analog only inputs. Surprisingly, I don't find any difference in sq with the analog inputs vs the digital. I guess using monster cable brand RCA cables helps a little huh?
